Which steel mill and grade? What hardness after heat treatment? Do you provide material certificates and heat treatment reports?

We select materials per product requirements and deliver with full transparency: Steel grade:For optical/transparent parts -Sweden ASSAB S136 SUP (or equivalent import), HRC 48-52.For structural parts-Baosteel SWG 718H pre-hardened,HRC 33-37. Documentation: Supplied with original mill certificates, our in-house heat treatment furnace temperature curves, and per-piece hardness inspection records. Core components (cores, slides) are stamped with serial numbers for lifetime traceability.

Do you heat-treat core components (cores, slides) in-house or outsource? How is the process controlled?

All critical heat treatment is performed in our wholly-owned heat treatment workshop -never subcontracted to small shops. Process controls include: Vacuum quenching + cryogenic treatment for minimal distortion; Furnace coupons per batch with metallographic inspection to ensure grain size compliance; Minimum two tempering cycles post-quench to relieve stress. We stand behind our process.

What is the design life in shots?

Design life is contractually guaranteed: S136 high-polish molds: 1,000,000+ shots. 718H class: 500,000+ shots (excluding normal wear). Warranty: typically 18 months after mold acceptance or first 80% of design life, whichever comes first. During this period, any non-human-induced core cracking, slide fracture, ejector plate deformation, etc., will be remade or repaired free of charge, with downtime labor costs compensated per agreed rates.

How are the cooling channels routed? Straight-line or conformal cooling? What mold temperature uniformity do you guarantee?

Cooling design is the core of efficiency and yield. Our approach: Mold flow analysis first to optimize cooling, delivering a 'Cooling Time vs. Mold Temperature Uniformity'report. Conformal cooling inserts (laser-sintered) or high-efficiency beryllium-copper inserts for hot spots and deep cavities;straight/baffle channels elsewhere.Critical zone temperature variance kept within plus or minus 3 degree Celsius Guaranteed improvement: Our cooling solution can reduce cycle time by 10-25% vs. convent

How many cavities do you recommend? Provide a comparison of 1-cavity vs. 2-cavity: output, yield, and mold cost.

We don't push -we present an investment analysis: Option A (1+1):Lower mold cost, easy maintenance, stable yield - ideal for fluctuating order volumes. Option B (1+2): ~80% higher mold cost, but ~25% lower per-unit cost and doubled output - ideal for stable high-volume orders. We'll provide total mold price, estimated cycle time, daily output, and payback period for both, so you can decide based on your order forecast.

What hot runner brand? Manifold heating method? Include extra thermocouples and heater bands as spares.

We only use field-proven brands: Brands: YUDO, HRS, Mould-Tip, BEST, SURE. Manifolds use integrated tubular heaters or embedded cartridge heaters for uniform thermal distribution. Standard spares included free: 2 full sets of thermocouples (all specs), 2 sets of heater bands (main nozzle + manifold), and 1 set of manifold seals.

Must the trial run be at your factory? Can I bring my molding technician to watch and measure dimensions on-site?

Absolutely -this is our standard service: The entire trial is open to you. We strongly recommend bringing your molding tech and QC inspector; using your designated injection machine is even better. We have CMM and vision measurement equipment on-site -parts are inspected immediately, and dimensional reports are confirmed on the spot. We only proceed to the next step after you sign off the trial report.

If your machining equipment fails, do you have backup partner factories? How do you guarantee my delivery date?

We have a robust contingency mechanism: Capacity-sharing and emergency collaboration agreements with 3 peer mold shops. Critical equipment - 5-axis CNC, wire EDM, die spotting presses - all have backup resources. If primary equipment fails, backup activates within 4 hours, machining data syncs via cloud, and maximum schedule deviation is capped at 2 working days. You will be notified immediately -we never leave you in the dark.

Provide a wear-parts list with part numbers and suppliers. How many spare sets are included with the mold?

Standard spare parts delivered with the mold: Wear-parts list: Detailed breakdown of ejector pins, sleeves, slide wear plates, springs, locating rings- including part numbers and OEM suppliers. Included free: 2 pieces of each ejector pin and sleeve spec, full spring set, 1 set of wear plates, 1 spare set of hot runner heating elements, plus assorted water fittings and plugs. Ready for stable production from day one- no extra parts to source.

FAQ

Which steel mill and grade? What hardness after heat treatment? Do you provide material certificates and heat treatment reports?: We select materials per product requirements and deliver with full transparency: Steel grade:For optical/transparent parts -Sweden ASSAB S136 SUP (or equivalent import), HRC 48-52.For structural parts-Baosteel SWG 718H pre-hardened,HRC 33-37. Documentation: Supplied with original mill certificates, our in-house heat treatment furnace temperature curves, and per-piece hardness inspection records. Core components (cores, slides) are stamped with serial numbers for lifetime traceability.
Do you heat-treat core components (cores, slides) in-house or outsource? How is the process controlled?: All critical heat treatment is performed in our wholly-owned heat treatment workshop -never subcontracted to small shops. Process controls include: Vacuum quenching + cryogenic treatment for minimal distortion; Furnace coupons per batch with metallographic inspection to ensure grain size compliance; Minimum two tempering cycles post-quench to relieve stress. We stand behind our process.

Warranty: typically 18 months after mold acceptance or first 80% of design life, whichever comes first. During this period, any non-human-induced core cracking, slide fracture, ejector plate deformation, etc., will be remade or repaired free of charge, with downtime labor costs compensated per agreed rates.
How are the cooling channels routed? Straight-line or conformal cooling? What mold temperature uniformity do you guarantee?: Cooling design is the core of efficiency and yield. Our approach: Mold flow analysis first to optimize cooling, delivering a 'Cooling Time vs. Mold Temperature Uniformity'report. Conformal cooling inserts (laser-sintered) or high-efficiency beryllium-copper inserts for hot spots and deep cavities;straight/baffle channels elsewhere.Critical zone temperature variance kept within plus or minus 3 degree Celsius Guaranteed improvement: Our cooling solution can reduce cycle time by 10-25% vs. convent
How many cavities do you recommend? Provide a comparison of 1-cavity vs. 2-cavity: output, yield, and mold cost.: We don't push -we present an investment analysis: Option A (1+1):Lower mold cost, easy maintenance, stable yield - ideal for fluctuating order volumes. Option B (1+2): ~80% higher mold cost, but ~25% lower per-unit cost and doubled output - ideal for stable high-volume orders. We'll provide total mold price, estimated cycle time, daily output, and payback period for both, so you can decide based on your order forecast.

Critical equipment - 5-axis CNC, wire EDM, die spotting presses - all have backup resources. If primary equipment fails, backup activates within 4 hours, machining data syncs via cloud, and maximum schedule deviation is capped at 2 working days. You will be notified immediately -we never leave you in the dark.
