As part of the mold base and materials procurement process.the various types of metals must also be selected.Just as there are many different plastics suitable for injection molding,there are many ferrous and non-ferrous metals that are suitable for use in injection molds.           Some of the more common metals and their properties are provided in Appendix B.Of all these metals,AISI P20 is the most common due to it's favorable combination of properties.However,P20 is sometimes improperly specified in many molding applications since other metals would provide better performance,lower mold molding making cost,or materials will be discussed.     Hello,i am Cherry,if you need more details,pls contact me by email:injectionmold2008@163.com.
