Case Study: The plumbing industry requires tight dimensional tolerances – the structural foam process delivers. Since there are multiple injection points, and cavity pressures are less than 500 psi in most cases, there is little to no internal stress molded into the part. The result is dimensional repeatability.
Unique Features:
- Parts hold single millimeter tolerances
- Improved flatness – reduced warpage
- Ability to change pipe fitting sizes with quick-change inserts
Process Replaced:
- Injection molding
Advantages for the Customer:
- Lower tool cost with aluminum tools
- Lower tool maintenance costs
- Increased part performance
- Ability to run on smaller SF machines than on very large, expensive injection machines
