THE MOLDMAX® ADVANTAGE
Through the unique combination of thermal conductivity and strength available in The MoldMAX product line, these copper mold alloys provide:
- Shorter cycle time
- Improved plastic part dimensional control
- Better parting line maintenance
- Excellent corrosion resistance
MoldMAX provides strength and wear resistance similar to that of many tool steels. In addition, MoldMAX offers a thermal conductivity up to ten times greater than steel and comparable to aluminum. MoldMAX is typically specified for:
- Injection mold components and cavity inserts
- Blow mold pinch offs, neck rings and handle inserts
- Hot runner system injection nozzles and manifolds
MoldMAX SC provides the highest thermal conductivity available in a mold material…ten times greater than steel and twice that of aluminum. MoldMAX SC also offers a hardness and strength exceeding aluminum. MoldMAX SC is specifically designed for foam processing, hot runner systems, blow molds and other applications where maximum heat removal or control is required.
