Home Resource Center Technical Papers Alloys MoldMax Alloys MoldMax® Alloys FOR PLASTIC TOOLING Resources Our library of Tech Briefs offers in-depth information covering a range of topics related to our MoldMAX plastic tooling alloy products, including cleaning, weld repair, EDM of MoldMAX molds and more. If you cannot find the information you need or would like to request additional technical product details, please feel free to contact us for more information. Testing Molded Plastic Food Containers for Beryllium Transfer Discussed in this document, a study initiated by Materion’s Product Stewardship department demonstrates that the use of copper beryllium as a plastic tooling alloy does not risk the transfer of beryllium to the finished molded, plastic product. Weld Repair of MoldMAX V Alloy Unlike MoldMAX products made up of copper and beryllium, MoldMAX V is made of copper, nickel and silicon, and it does not weld easily. Machining Guide for MoldMAX® and PROtherm® Mold Alloys This Tech Brief covers recommendations about machining MoldMAX® and PROtherm® mold alloys for plastic mold making. Cleaning MoldMAX Molds This Tech Brief covers procedures to remove corrosion and brighten the surface of MoldMAX® molds. EDM Of MoldMAX This Tech Brief covers the electrical discharge machining of copper beryllium mold materials, including MoldMAX® and PROtherm®. Polishing MoldMAX Molds This Technical Brief includes detailed information about polishing the surface of MoldMAX® and PROtherm® high performance mold alloys. Processing PVC With MoldMAX Processing polyvinyl chloride (PVC) can create hydrochloric acid (HCl) that can corrode even corrosion-resistant MoldMAX tools. Damage to tooling by HCl can be prevented by proper compounding, processing and maintenance. Surface Coatings For Plastic Molds Using MoldMAX Alloys MoldMAX alloys often have sufficient surface hardness to resist wear and abrasion caused by the injected resin or the mold parting line. When additional hardness is required, MoldMAX may be coated with a harder material. Weld Repair Of MoldMAX and PROtherm Mold Alloys MoldMAX HH® , MoldMAX LH® and PROtherm® copper beryllium alloys can be effectively and safely welded using conventional welding equipment and processes.
