A styrene-based, expendable pattern casting material, compatible with most standard foundry processes.

Applications

Create patterns directly rather than through indirect methods

Complex investment casting patterns

Reactive metals like titanium

Low melt-temperature metals such as aluminum, magnesium and zinc

Ferrous and non-ferrous metals

Economic, low-volume production castings without tooling

Smaller parts can be joined to create very large patterns

Sacrificial, expendable patterns

Features

Functions like foundry wax and is "foundry friendly"

Low residual ash content (less than 0.02%)

Short burnout cycle

Easy-to-process plastic

Good plastic powder recycle characteristics

Benefits

Create complex patterns without welds or joints

Reduce lead times resulting in faster time-to-market

Compatible with autoclaves, low-temperature furnaces, and vacuum plaster casting methods

Easy to assemble and repair patterns

Rapidly test new designs in iterative process
