Master unit die molds lower total costs and turnaround time for prototype revisions. The inserts can be easily removed, redesigned, and re-inserted while leaving the larger part of the tool in the injection mold machine. If there is a requirement for significant repairing or adjustment to the injection molded part then MUD inserts are a good option. Making prototype molds is as much an art as it is a science.

Ramtec has the complete package necessary to deliver on any prototype mold project - one time or on a long-term basis. Our equipment allows us to perform simultaneous operations and minimize turnaround time. Combined with our 30 years of mold manufacturing know-how, this equipment investment has allowed us to deliver on the precise and cost-effective prototype mold manufacturing services that we claim.
