Precision molded plastics

Precision molded plastics

When you need precision plastic parts in bulk, custom injection molds and molding will meet your needs for plastic product tolerances.

Muyoung  Mould is an ISO certified injection mold manufacturing and molding company with advanced equipment and extensive experience in producing precision products, and we have been a trusted supplier for aerospace, medical and mechanical company.

Technical focus of Precision molded plastics

  • Clamping force: in the precision molding process, generally need a very high injection pressure to mold
  • Metering accuracy: To maintain high stability of plastic products, the amount of hot melt plastic injected into the mold cavity must be equal each time.
  • Injection speed: injection speed is an important function of precision injection molding machine
  • Injection pressure: Precision injection molding requires higher injection pressure to improve the density of plastic products, reduce shrinkage deformation and ensure the accuracy of plastic products.
  • Pressure-holding: reasonable pressure-holding time has an important influence on the accuracy of plastic products.
  • Mold temperature: The temperature change of mold cavity surface should be controlled within ±1℃.

H13 steel is the most widely used and most representative hot work die steel grade, its main characteristics are

(1) High hardenability and high toughness.

(2) Excellent resistance to thermal cracking and can be water cooled in the workplace.

(3) Medium wear resistance, carburizing or nitriding can also be used to improve its surface hardness, but to slightly reduce the resistance to thermal cracking.

(4) Poor secondary hardening ability in tempering due to its low carbon content.

(5) Softening resistance at higher temperatures, but a rapid drop in hardness at operating temperatures above 540°C (1000°F) (i.e. a working temperature of 540°C can be tolerated).

(6) Small deformation from heat treatment.

(7) Moderate and high machinability.

(8) Medium resistance to decarburization.
