Exceeding 230\u00b0C will degrade the polyurethane structure, leading to low viscosity and severe flashing.<\/li>\n
  • Low Mold Temperature:<\/strong> Maintained cold between 15\u00b0C and 40\u00b0C (59\u00b0F to 104\u00b0F) using pressurized water chillers. Rapid cooling is mandatory to prevent the soft elastomeric part from sticking to the mold core.<\/li>\n

We apply vapor-honed or bead-blasted textures on core\/cavity surfaces and implement broad ejector pins or stripper plates to ensure clean release.<\/li>\n
  • High Elastic Shrinkage:<\/strong> TPU exhibits high shrinkage (typically 1.0% to 2.0% depending on durometer hardness). Our tooling division scales mold cavities precisely to compensate for this shrinkage.<\/li>\n<\/ul>\n<\/section>\n
