  • High PrecisionEnsures stable assembly and minimizes flash.
  • Design OptimizationExtrusion/molding/injection analysis – reduces defects & shortens cycle time.
  • Premium SteelHeat treatment & surface coating tailored to production volume.
  • Fast SupportMaintenance, refurbishment & improvement of running molds.

Rubber Molds

Design optimized for vulcanization, filling, and venting; improves durability and dimensional repeatability.

Rubber Molding Die (Compression/Transfer/Injection)

Reasonable runner & vent layout, shrinkage calculation, and flash control at parting lines, 3–5 axis CNC, surface/cylindrical grinding, EDM, mirror polishing; mold refurbishing & productivity enhancement.

Process Optimization for Extrusion & Molding

Use flow and thermal simulation to balance sections, equalize temperature, and reduce expansion and warpage.

  • Micro vent design
  • Rubber shrinkage analysis
  • Compound proposal & post-curing treatment

Plastic Production Molds

Optimizing flow – cooling – venting for injection, extrusion, and thermoforming; reducing cycle time and surface defects.

Injection Mold

Proper gate, runner & cooling system layout; resin shrinkage, deformation & flash control.

PVC Extrusion Die

Die design for PVC pipes/profiles with stable cross-sections & uniform wall thickness; heating & cooling draw-down advisory.

Vacuum/Thermoforming Mold

Vacuum hole layout, transition radius, and venting design; mold material suggestion & rib reinforcement for rigidity.

DFM/DFA Solutions for Plastics

Review wall thickness, draft angles, rib layout, ejector pins, A/B surfaces; propose improvements before mold approval.

  • Moldflow simulation analysis
  • Hot runner / cold runner design
  • Preventive maintenance plan per cycle
