MoldStar®150 & MoldStar®90
The High-Performance, Beryllium-Free Copper Alloys
For The Blow Molding & Injection Molding Industries

The plastics industry has proven MoldStar®150 & MoldStar®90 dependable as the materials of choice for blow molding and injection molding applications.

In many mold applications, the placement of cooling passages is dictated by mold shape, size and complexity. The excellent thermal conductivity of our alloys helps compensate for uneven wall thickness or part configuration.

In a tested application, core temperatures during mold cycles ranged from 120-1400F with tool steel components. The addition of our copper alloys as inserts or major cores reduced temperatures to 80-900F.  In addition to lower temperatures, there was less of a temperature variation, resulting in greater stability from cavity to cavity. 

In addition to superior thermal conductivity, MoldStar®150 and MoldStar®90 offers the following advantages:
  • Accepts and maintains high surface finishes 
  • Accepts etching and texturing.
  • Offers welding compatibility with other copper alloys, tool steels and stainless steels to provide composite materials for increased surface hardness in specific areas.
  • Requires no additional heat treatment. 
  • Retains the inherent corrosion resistance of copper. 
  • Can be readily machined using conventional practices as well as the electrical discharge method (EDM).
