Molded & Overmolded Components
High-Precision Multi-Material Components for Enhanced Performance
Master the connection where high-grade metal meets high-performance polymers.
The insert molding process at PML follows these precision steps:
Metal or plastic insert is accurately positioned in the mold.
The mold closes, securing the insert in place.
Thermoplastic material is injected around the insert.
The part solidifies under controlled cooling.
The molded component is removed from the mold.
Excess material is trimmed, and the part is inspected.
At PML, we specialize in multi-insert moulding with tight tolerances up to ±0.05 mm, depending on raw material grade and part geometry.
PML is equipped with advanced insert moulding machines for a wide range of component sizes and applications:
| Tool Type | Function |
|---|---|
| Custom Molds | Shape and hold inserts during injection molding |
| Insert Holders | Secure placement of connectors and terminals |
| Injection Mold Cavities | Create complex geometries around inserts |
| Ejection Systems | Remove parts post-cooling with minimal deformation |
| Thermal Regulation Units | Maintain optimal flow and curing conditions |
