Low Pressure Casting Process

Low-Pressure Casting Technique - Kurtz Ersa

The low-pressure casting process proves itself to be predestined for the conversion of exceptionally high quality demands. In low-pressure casting, the furnace is pressurized whereby the molten aluminum is brought into the casting die through the riser tube. The die is filled by slowly climbing, controlled, and above all, constant pressure.

Low Pressure Molding (LPM) | Cavist

Low Pressure Molding (LPM) uses thermoplastic materials with very low viscosity, allowing for overmolding and encapsulation of even the most sensitive circuit board assemblies. Because the materials are natural adhesives, the process is well-suited to sealing circuitry against dirt, dust and moisture…in many cases, up to an IP-68 rating.
