Injection Molds

Precision injection molds for thermoplastics — from single-cavity prototype tools to high-volume multi-cavity production systems. Our engineers handle DFM and QC. Manufacturing by specialized partners.

Injection Mold Delivery

Injection molding is the most widely used plastic manufacturing process. Getting the mold right is the single most important factor in part quality and production efficiency.

Common Applications

  • Automotive interior and exterior components
  • Consumer electronics housings and enclosures
  • Medical device components
  • Packaging — caps, closures, thin-wall containers
  • Industrial equipment parts and connectors
  • Home appliance components

Steel Options for Injection Molds

The right steel depends on your production volume, plastic material, and surface finish. Our engineers guide your selection.

GradeHardnessBest For
P2028-32 HRCGeneral purpose, low-volume production
718H33-37 HRCMedium production, good polishability
NAK8038-42 HRCHigh polish, optical parts, lenses
S13648-52 HRCCorrosion resistant, medical, food-grade
H1346-50 HRCHigh-temp, die-casting, engineering resins
M33350-54 HRCHigh-wear, glass-filled materials

Our QC for Injection Molds

Every injection mold goes through our comprehensive QC checklist — independently verified, not factory self-inspected.

1CMM dimensional inspection — full report with GD&T
2Mold trial — sample parts with measurement data
3Steel certification — grade verification via spectrometer
4Hardness testing — cavity and core before and after heat treatment
5Cooling circuit — flow rate and pressure test
6Ejection system — full function and cycle test
7Surface finish — visual inspection under standardized lighting
8Rust prevention and export crating verification
