For diecasting, the options for rapid manufacturing are machined tooling, laser-based die insert
fabrication and plaster molding.
The die insert
induces melt redistribution, resulting in layered extruded films by altering the discrete thermoplastic resin streams in a film extrudate at the die lip, in the die, or before the die.

casting and comprised of the facing layer and the chamotte-basis backing layer.
The use of HEAT can also enhance small-volume-parts production of stamping die insert
blocks, variable thickness punches, mold cores, inserts, and slide blocks.
As a die insert
moves from the back to the front of the die case, it doesn't have to be pressed the full length of the bore in the case, like a straight die does.
Normal die insert
costs using SLS fall between $6,000 and $8,000.
Once a die insert
is treated, the tool often lasts 10 times longer.
A rash of large H-13 diecasting die insert
failures prompted a study that revealed a corrosion fatigue mechanism as the culprit.

Among the parts Philadelphia Carbide has manufactured are products as diverse as water jet plungers, punches, dies and die inserts
, high viscosity mixer pins, homogenizer replacement parts, industrial guide rings (G rings), contact tips and pads.
