Tool design→Die casting→Deburring→CNC finishing→Plating / paint / anodising→CMM inspection
Common Pain Points
  • One design rarely fits all steering-wheel diameters
  • Colour drift and porosity across large batches
  • Inconsistent critical holes causing rattles after assembly
  • Long changeover times versus supply cadence
Selected Cases
Steering wheel assister · zinc casting + 4-colour anodised ring
ChallengeClamp design must fit many wheel diameters, with tight tolerance between magnetic base and ring.
ApproachOne-piece cast clamp, toleranced magnetic seat, knurled grip surface; colour-swappable anodised ring with badge/LOGO customisation.
DeliveryPrototype → test fit → volume, with tiered pricing and OEM/ODM support.
Bearing bracket · casting + critical-hole machining
ChallengePosition and concentricity of critical holes drive running smoothness.
ApproachCast with stock allowance, then CNC-finish the critical holes to drawing tolerance; CMM report shipped with goods.
DeliverySmall-batch prototyping and test fitting, with batch sampling and process records in volume.

Common Pain Points
  • Weight reduction versus structural strength
  • Uneven fin walls causing incomplete fill
  • Mounting-hole accuracy affecting whole-pack assembly
  • Material and process must meet environmental rules
Selected Cases
Heat-sink part · integrally cast fins
ChallengeNarrow fin pitch and thin walls are prone to incomplete fill.
ApproachFin pitch and wall thickness optimised against both thermal requirement and casting feasibility; venting and gating designed in, then tuned over trial shots.
DeliveryTrial samples for thermal validation before volume release.
Aluminium mounting bracket · lightweight + machined holes

FAQ

FAQ

Answers to the questions customers ask most about our services and capabilities

How long does mold development usually take?

Simple molds take 15-20 days; complex molds 25-35 days, depending on part geometry, mold size and tolerance. We confirm an exact schedule after evaluation.

What is your MOQ?

No MOQ for mold development. Die castings typically start at 500 pcs, negotiable by part and process. Low-volume prototyping is welcome.

Can you provide samples?

Yes. T0/T1 trial shots are free after mold completion; standalone prototyping carries a sample fee, refundable once volume reaches the agreed quantity.

What payment terms do you accept?

Mold: 50% deposit, 50% after successful sampling. Production: 30% deposit, 70% before shipment. Credit terms negotiable for long-term partners. T/T, WeChat Pay and Alipay accepted.

How are quality issues handled?

For defects on our account we repair, replace or refund free of charge including freight. Non-human mold damage within warranty is repaired free so your production is never interrupted.

Do you export? Which trade terms?

Yes — we ship worldwide. EXW/FOB/CIF supported. We assist with customs and inspection paperwork and provide English drawings and inspection reports.
