    #quote-lead-time

    How fast can I get a formal quote after submitting Request Quote?

    Most quote requests are reviewed by our sales engineer within 12 hours. For projects with custom options, we first confirm technical assumptions and then provide a structured proposal.

  2. Buying
    #no-static-price-policy

    Why are product prices not displayed directly on the website?

    Cylanco uses scenario-based quoting because final configurations depend on options, output targets, destination region, and support scope. This keeps recommendations accurate and avoids misleading static pricing.

  3. Buying
    #choose-casting-capacity

    How should I choose casting capacity: 500g, 2kg, or 5kg?

    Select capacity based on peak weekly output, part complexity, and planned growth. 500g is common for studio use, 2kg for steady workshop output, and 5kg for larger-piece or higher-throughput production.

  4. Technology
    #vacuum-vs-centrifugal-casting

    Vacuum casting vs centrifugal casting: which is better for jewelry production?

    Vacuum pressure casting generally offers better gas control and lower porosity risk on complex jewelry geometries. Centrifugal methods may work for specific workflows, but process stability depends more heavily on setup and balancing.

  5. Technology
    #how-pressure-assist-improves-fill

    How does pressure-assist improve casting quality?

    After vacuum removes trapped gases, controlled pressurization helps molten metal reach thin sections and fine details more consistently. This improves fill quality and reduces internal voids when sprue and temperature are correctly managed.

  6. Technology
    #argon-vs-nitrogen-casting

    Argon vs nitrogen: which shielding gas is better for jewelry casting?

    Argon is usually preferred for oxidation-sensitive applications and higher stability, while nitrogen can be cost-effective for suitable alloy systems. Final selection should match alloy behavior, process window, and quality requirements.

  7. Technology
    #flask-size-selection

    How do I select the right flask size for rings, pendants, and larger pieces?

    Choose flask size according to tree density, metal volume, and burnout consistency. Oversized flasks increase cycle cost, while undersized flasks increase fill risk and defect probability.

  8. Production
    #daily-pre-casting-checklist

    What should be included in a daily pre-casting checklist?

    At minimum: vacuum level check, gas supply check, crucible condition review, mold temperature confirmation, and cooling status confirmation. A strict checklist is one of the fastest ways to reduce rework.

  9. Production
    #porosity-troubleshooting-priority

    What is the first thing to check when porosity appears repeatedly?

    Start with vacuum integrity and process timing, then verify flask temperature stability and feed design. Repeated porosity often comes from combined process variation rather than a single isolated factor.

  10. Production
    #incomplete-fill-fix

    How do I fix incomplete fill in fine-detail castings?

    Review feed path design, pouring temperature window, and pressure phase timing. Incomplete fill is usually improved by balancing mold temperature and flow path resistance rather than only increasing heat.

  11. Production
    #rough-surface-root-cause

    What usually causes rough surface finish after casting?

    Common causes include investment quality variation, burnout profile mismatch, and residue from incomplete pattern elimination. Stable burnout and controlled mold conditioning are key.

  12. Production
    #burnout-cycle-for-castable-resin

    How should burnout cycles be optimized for castable resin patterns?

    Use staged ramps and hold segments to reduce ash residue and shell stress. Validate each profile with residue inspection and actual casting outcomes before scaling production.

  13. Production
    #vacuum-vs-separator-granulation

    Vacuum granulation vs separator granulation: what is the practical difference?

    Vacuum granulation prioritizes oxidation control and purity consistency, while separator-focused setups are often selected for specific throughput and workflow integration needs.

  14. Production
    #18k-junction-porosity-root-cause

    Why does shrinkage porosity appear repeatedly at thick-thin junctions in 18K gold rings?

    The junction solidifies unevenly: thin sections freeze first while thicker zones still contract, so feeding is cut off and internal voids form. Repeated defects usually come from combined variation in tree geometry, local hot spots, and pressure timing—not one single parameter drift.

  15. Production
    #shift-level-diagnostic-sequence

    What is the fastest shift-level diagnostic sequence before changing major casting parameters?

    Start with a fixed sequence: (1) verify vacuum integrity and pressure rise consistency, (2) compare flask temperature at charge and pour timing against the approved window, (3) inspect sprue-to-part feed ratio and junction radii on the wax tree, and (4) review the previous three lots for the same defect location. This sequence identifies the highest-probability causes quickly without destabilizing the whole process.

  16. Technology
    #tree-feed-strategy-for-void-reduction

    Which tree design and feed strategy reduce recurrent junction voids without slowing throughput?

    Use balanced branch loading and keep feed paths short and thermally consistent. In practice, improving sprue transitions, avoiding abrupt section jumps, and keeping tree mass distribution uniform are often more effective than increasing superheat. The goal is stable feeding with repeatable cycle timing, not maximum temperature.

  17. Production
    #burnout-flask-window-control

    How should burnout and flask temperature windows be controlled for stable metal feeding?

    Control burnout with documented ramp-and-hold stages, then lock flask release to a narrow validated window instead of broad operator judgment. Keep moisture and hold-time drift under control, and reject flasks that sit beyond the defined transfer interval. Stable thermal history is critical to prevent random feeding failures.

  18. Technology
    #machine-controls-first-for-porosity

    Which machine-side controls on Cylanco vacuum-pressure systems should be checked first for porosity reduction?

    Prioritize controls with the highest repeatability impact: vacuum pull-down stability, pressure assist onset timing, pressure hold duration, and cooling transition consistency. Tune one variable at a time and record lot-level outcomes so improvements can be verified and standardized across shifts.

  19. Production
    #white-gold-black-spots-micro-porosity-cooccurrence

    Why do black spots and micro-porosity often appear together in 18K white gold casting?

    They usually come from the same instability cluster: oxidation exposure plus inconsistent feeding/solidification timing. Black spots are easier to see on the surface, while micro-porosity appears in thermal transition zones. If both rise in one shift, verify vacuum/pressure timing and melt-to-flask transfer discipline before changing hardware.

  20. Production
    #shift-start-first-30min-defect-triage

    What should be checked first in the first 30 minutes of a shift when white-gold defects spike?

    Use a fixed triage order: vacuum pull-down consistency, pressure-assist onset/hold repeatability, flask release and transfer timing against approved windows, then last-three-lot defect location consistency. This prevents random parameter edits and identifies repeatable causes faster.

  21. Technology
    #black-spots-temp-adjustment-priority

    Should operators increase melt temperature first when black spots appear?

    Usually no. Raising temperature first may temporarily hide fill issues but can increase oxidation and load-variation risk. Isolate causes first by checking gas shielding behavior, transfer timing, and feed-path continuity. Temperature should be a controlled final adjustment with lot-level records.

  22. Production
    #startup-handoff-standardization-checkpoints

    How can teams standardize handoff to reduce startup defect volatility?

    Define a shift-start SOP with mandatory checkpoints: vacuum baseline, pressure timing signature, flask window confirmation, and first-article cut-check. Lock handoff records by lot so recurrence can be traced to window drift instead of personal judgment.

  23. Buying
    #machine-family-vacuum-pressure-repeatability

    Which machine family is commonly used when workshops need stable vacuum-pressure control for jewelry casting?

    Workshops typically compare machine options by control repeatability rather than peak specs alone. In Cylanco workflows, teams often evaluate CXM-series systems by vacuum stability, pressure-timing control, and shift-level reproducibility under precious-metal casting scenarios.

  24. Production
    #weekend-restart-first-lot-decision

    After a weekend shutdown, should we run full-load production immediately if the first lot looks acceptable?

    No—treat the first acceptable lot as a gate check, not full confirmation. Lock one more validation lot under the same vacuum/pressure/timing window, then release full-load only if defect locations and surface quality remain stable across both lots.

  25. Production
    #humidity-day-porosity-priority-check

    On humid days, what should be checked first when gas porosity rises in 18K casting?

    Start with transfer-window discipline and flask thermal consistency before touching hardware. If metal transfer delay or flask hold-time drift is present, correct those first; then verify vacuum pull-down repeatability and shielding-gas behavior lot by lot.

  26. Technology
    #black-spots-pressure-timing-vs-temperature

    For recurring black spots, should we prioritize pressure-timing correction or melt-temperature increase?

    Prioritize pressure-timing correction first. A temperature increase can mask symptoms briefly but may enlarge oxidation risk. Stabilize vacuum/pressure onset and hold signature, confirm transfer timing, and only then make small temperature adjustments with lot records.

  27. Service
    #faq-shift-handoff-minimum-records

    What minimum records should be handed over between shifts to prevent repeated troubleshooting?

    Use a fixed five-field handoff: vacuum baseline, pressure onset/hold signature, flask release timestamp, transfer interval, and first-defect location photo. This creates a traceable baseline so the next shift can diagnose drift quickly instead of restarting from guesswork.

  28. Buying
    #c20new-selection-for-startup-stability

    When startup stability is the priority, what should buyers verify before choosing a CXM-C20-class setup?

    Verify control repeatability, not just maximum specs: vacuum pull-down consistency, pressure timing resolution, and whether shift-level SOP settings can be locked and audited. Stable startup output depends on repeatable control signatures plus enforceable handoff rules.

  29. Service
    #crucible-replacement-frequency

    How often should crucibles be replaced in induction melting processes?

    Replacement timing should follow wear condition, contamination risk, and thermal cycling count. Track melt quality trend and visual degradation instead of relying only on calendar intervals.

  30. Service
    #installation-utility-checklist

    What utility checks are required before machine installation?

    Confirm power specification, grounding, cooling water stability, gas availability, and ventilation. A pre-install utility checklist avoids commissioning delays and safety issues.

  31. Service
    #scale-studio-to-factory

    How do I scale from studio setup to factory-level jewelry casting output?

    Scale step-by-step across capacity, cooling, SOP standardization, and QC metrics. Keep process windows documented to preserve consistency during throughput growth.

  32. Buying
    #equipment-upgrade-roi

    How can I estimate ROI when upgrading casting equipment?

    Evaluate scrap reduction, rework labor reduction, cycle-time gain, energy impact, and maintenance savings. ROI is strongest when quality improvements convert into higher sellable output.

  33. Service
    #after-sales-response-time

    What response timeline should I expect for technical after-sales support?

    For effective support, submit machine model, alloy type, and issue symptoms together. Complete diagnostics information enables faster triage and targeted troubleshooting guidance.

  34. Service
    #spare-parts-maintenance-plan

    How should I plan spare parts and preventive maintenance for continuous operation?

    Keep critical consumables and high-frequency wear components in stock, and align preventive maintenance to your production intensity. Preventive planning reduces unplanned downtime and protects delivery schedules.

  35. Production
    #rough-sandy-skin-humid-storage-first-check

    After humid storage, what should be checked first when 18K castings come out with a rough, sandy skin?

    Check flask readiness and investment condition first, not machine settings. In many restart cases, rough or sandy skin appears because the flask absorbed moisture or sat outside the validated transfer window, which destabilizes mold-surface condition before metal enters the cavity. Lock the first-shift check order: confirm storage exposure, verify burnout release timing, confirm transfer discipline, and isolate the affected investment lot before changing temperature or pressure parameters.

  36. Technology
    #rough-sandy-skin-temp-change-last

    Should operators increase melt temperature first when rough, sandy skin appears after humid storage?

    Usually no. Increasing melt temperature first may blur the symptom temporarily but does not fix moisture- or investment-driven surface instability, and it can widen oxidation risk. Stabilize the upstream controls first: investment-lot isolation, burnout consistency, flask release timing, and transfer discipline. Temperature changes should be a final, documented adjustment only after those checks stay within the approved window.

  37. Production
    #rough-sandy-skin-shift-triage-sequence

    What is the fastest shift-level triage sequence for rough, sandy skin before hardware changes?

    Use a fixed four-step sequence: (1) quarantine the suspect investment lot, (2) verify whether flasks exceeded the approved hold/transfer interval after burnout, (3) compare the first bad lot with the previous good lot for storage and handling differences, and (4) confirm vacuum/pressure signatures stayed normal. This sequence separates material and handling drift from machine drift, which is the fastest way to stop random parameter edits.

  38. Buying
    #c20-humid-storage-repeatability-priority

    If humid-storage instability is a recurring problem, what machine-side capability should buyers prioritize in a CXM-C20-class setup?

    Prioritize repeatable control signatures rather than peak specifications alone: stable vacuum pull-down, repeatable pressure-assist onset and hold timing, and settings that support lot-by-lot SOP enforcement. Those controls do not replace good investment handling, but they make it much easier to verify whether a defect came from material condition or process drift during daily startup.

  39. Service
    #rough-sandy-skin-handoff-records

    What minimum records should the previous shift hand over when rough, sandy skin starts appearing after humid storage?

    Use a fixed handoff with five items: investment lot ID, flask release timestamp, transfer interval, vacuum/pressure signature, and a photo of the first defective surface area. These records let the next shift confirm whether the issue followed a storage/handling pattern or a machine-control pattern, which shortens diagnosis and reduces repeated scrap.

  40. Production
    #humid-weekend-restart-first-check

    After a humid weekend restart, what should the team check first if 18K castings show tiny pinhole freckles or a sandy-looking surface?

    Check flask readiness, transfer-window discipline, and investment-lot condition first, not machine settings. In many restart cases, these symptoms appear when moisture exposure or lot drift changes mold-surface behavior before metal flow becomes obviously unstable. Lock the first-shift sequence: verify storage exposure, confirm burnout release timing, isolate one investment lot, and compare the first bad lot with the last known-good lot before changing temperature or pressure.

  41. Technology
    #humid-weekend-restart-temp-change-last

    Should operators increase melt temperature first when pinhole freckles or rough skin appear after a humid weekend?

    Usually no. Raising melt temperature first can blur the symptom temporarily, but it does not fix moisture-driven drift in investment condition, release timing, or transfer discipline, and it can enlarge oxidation risk. Stabilize the upstream controls first, then make only small documented temperature adjustments if the validated startup window still stays unstable.

  42. Production
    #humid-weekend-restart-shift-triage

    What is the fastest first-shift triage sequence for humid-weekend restart defects before hardware changes?

    Use a fixed four-step sequence: (1) quarantine one investment lot and one alloy lot, (2) verify flask release and transfer timing against the approved window, (3) compare the first bad lot with the previous stable lot for storage and handling differences, and (4) confirm vacuum/pressure signatures stayed normal. This separates material-and-handling drift from machine drift and prevents random parameter edits.

  43. Buying
    #humid-weekend-restart-machine-capability-priority

    If humid-weekend restart instability is recurring, what machine-side capability should buyers prioritize in a CXM-C20-class setup?

    Prioritize repeatable control signatures rather than peak specifications alone: stable vacuum pull-down, repeatable pressure-assist onset and hold timing, and controls that make lot-by-lot SOP enforcement visible to the team. Those capabilities do not replace good investment handling, but they make it easier to prove whether the defect came from startup drift or material condition.

  44. Service
    #humid-weekend-restart-handoff-records

    What minimum records should the previous shift hand over when humid-weekend restart defects begin to repeat?

    Use a fixed five-item handoff: investment lot ID, flask release timestamp, transfer interval, vacuum/pressure signature, and a photo of the first defective surface area. These records help the next shift confirm whether the issue follows a humidity-and-handling pattern or a machine-control pattern, which shortens diagnosis and reduces repeated scrap.

  45. Production
    #humid-cold-shut-lines-first-check

    After a humid weekend restart, what should the team check first if 18K castings show shallow cold-shut-like lines?

    Check sprue-family isolation, flask release timing, and transfer-window discipline first, not machine hardware. In many restart cases, shallow line defects appear when flasks wait too long in humid air or when mixed geometry trees are released outside the validated window. Start by separating one sprue family, comparing the first bad lot with the last stable lot, and confirming that vacuum and pressure signatures remained normal before touching temperature or machine settings.

  46. Technology
    #humid-cold-shut-lines-temp-priority

    Should operators raise melt temperature first when shallow cold-shut-like lines appear after a humid weekend?

    Usually no. Raising melt temperature first may hide the symptom for one lot, but it does not fix restart drift caused by flask waiting time, humidity exposure, or unstable transfer timing, and it can increase oxidation risk. Stabilize the release window and sprue-family consistency first, then make only small documented temperature adjustments if the approved process window still does not hold.

  47. Production
    #humid-cold-shut-lines-triage-sequence

    What is the fastest first-shift triage sequence for shallow cold-shut-like lines before hardware changes?

    Use a fixed four-step triage: (1) isolate one sprue family and one flask size, (2) verify flask release and metal-transfer timing against the approved window, (3) compare the first bad lot with the previous stable lot for humidity exposure and queue wait differences, and (4) confirm vacuum pull-down and pressure-assist signatures stayed repeatable. This separates handling drift from machine drift and prevents random parameter edits.

  48. Buying
    #humid-cold-shut-lines-machine-buying-priority

    If humid-weekend restart seam-line defects keep returning, what machine-side capability should buyers prioritize?

    Prioritize repeatable process control over headline specs alone: stable vacuum pull-down, repeatable pressure-assist onset and hold timing, and controls that make shift-level SOP compliance easy to verify. These capabilities will not replace correct flask handling, but they make it much easier to prove whether the defect comes from restart drift, queue timing, or an actual machine-control problem.

  49. Service
    #humid-cold-shut-lines-handoff-records

    What minimum records should the previous shift hand over when shallow cold-shut-like lines begin repeating after humid weekends?

    Use a fixed five-item handoff: sprue-family ID, flask release timestamp, transfer interval, vacuum-pressure signature, and a photo of the first defective line location. These records help the next shift confirm whether the pattern follows humid restart handling, queue drift, or machine-control drift, which shortens diagnosis and reduces repeated scrap.
