Key Features & Technical Advantages

• TiAlN Surface Coating
  Titanium Aluminum Nitride coating improves surface hardness, wear resistance, and thermal stability, reducing cavity wear during long production cycles.

• SUS303 Stainless Steel Substrate
  Provides good machinability, corrosion resistance, and dimensional stability for injection molding cavity components.

• High Dimensional Accuracy
  Precision machining with controlled tolerances ensures reliable part consistency across multi-cavity molds.

• Optimized Surface Quality
  Controlled surface finish supports stable plastic flow and reduces adhesion during demolding.

• Built-to-Print Manufacturing
  All cavity parts are produced strictly according to customer drawings and technical specifications.
