Silicone rubber is an ideal material for the injection molding
process due to its good flow characteristics and very fast cure at high temperatures.
In 1984, Hendry, now a consultant, introduced the SST process to a British structural-foam molder, Peerless Foam Molding
of the five different classes of TPEs can be relatively easy if you follow a few simple guidelines.
At the K 2004 show, Erlenbach Maschinen of Germany showed a video of molding
an automotive part in which solid PP shells are robotically loaded into the female half of a six-cavity EPP mold, while metal fittings are inserted with a fixture into the male half.
Many outsource some or all to custom molders, though perhaps no more than a dozen injection molders have experience molding
3D blow molding
also fosters parts integration, which opens avenues for cost cutting through eliminating assembly steps.
Internal gas molding
typically cores or hollows out a part, a rib, or bosses, while external gas molding
applies gas pressure to some or all of the nonappearance side of the part.
CPI practices and licenses technology for its "direct-feed thermoplastic" (DFT) process for compression molding
They will be fully integrated into the OEM's product-development cycle and will operate more like a contract manufacturer that has molding
as just one of its core competencies.
Multi-shot processes such as overmolding can drive down part costs by squeezing what would otherwise have been two distinct molding
jobs plus an assembly operation into a single manufacturing step.
Barber-Colman controls will also be featured on a new 20-ton insert press from Boston Matthews Injection Molding
Machinery of Dayton, Ohio.
Clamp-tonnage predictions are also enhanced by using pvT/compressibility material data to simulate the common molding
practice of stopping the ram before the cavity is completely filled, allowing the compressed melt to expand into the remaining area.
