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. Weld Repair of MoldMAX V Unlike MoldMAX products made up of copper and beryllium, MoldMAX V is made of copper, nickel and silicon, and it does not weld easily. 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.
