MoldMAX® Alloys Technical Resources 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. 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 Alloy Molds This technical brief descibes procedures to remove corrosion product from and brighten the surface of MoldMAX® molds. EDM Of MoldMAX Alloys This Technical Brief discusses the electrical discharge machining of copper beryllium mold materials, including MoldMAX® and PROtherm. Polishing MoldMAX and PROtherm Molds This Technical Brief discusses how to polish the surface of MoldMAX and Protherm high performance mold materials. Processing PVC With MoldMAX Tools Processing of polyvinyl chloride (PVC) can create hydrochloric acid (HCl) that can corrode even the 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 Family of 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 to enhance wear resistance and prolong tool life, MoldMAX may be coated with a harder material. 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. Weld Repair Of MoldMAX HH, MoldMAX LH and PROtherm Mold Materials MoldMAX HH, MoldMAX LH and PROtherm copper beryllium alloys can be effectively and safely welded using conventional welding equipment and processes. This paper presents guidelines and recommended welding and heat treating practices.
