Suppliers are offering injection molds made of durable materials or with tough surface finishes.

The latest injection molds from China now exceed the typical 500,000 to 1 million-shot life span, many reaching 3 million or 300 million cycles.

Makers are offering different materials and surface treatment options that strengthen and improve the form of the mold and parts created. A number of molds come in various types of steel, including stainless for better rust resistance, and are polished. Polishing makes the mold surface smooth. Some molds achieve a sleek mirrorlike polished look that also yields smooth parts. Other molds are textured or underwent EDM or Electrical Discharge Machining for the surfaces to transform into complicated or sharp shapes.

China-made injection molds are suitable for a range of applications. Molds in the featured selection are suitable for making parts for the medical, automotive, hardware, electronics and packaging industries.

The products in the gallery below were selected by our China-based Market Analyst for representing trends in injection molds.
