Molds for injection molding with ABS and SAN plastics

[FredB]

This really depends on the size/complexity and number of parts needed.

There is a thread on this here:

Injection molding with new high temp resin

I can understand you about the materials… it took me quite a lot of time and money to find the right materials, properties and techniques before I reached perfect castings. My company is making 99% engineering parts, most of them are complex and with tight tolerances. There are a lot of great urethanes with properties very, very close to those of the thermoplastics infact. After trying a lot of brands, I can say we are now settled using Axson and BJB - I can hardly tell the difference between t…

Part of that thread is pressurized castings (another good option)
