Molded & Overmolded Components
Insert Molded Parts
High-Precision Multi-Material Components for Enhanced Performance
The Seamless Fusion of Strength and Conductivity
Master the connection where high-grade metal meets high-performance polymers.
Manufacturing Process
The insert molding process at PML follows these precision steps:
Insert Placement
Metal or plastic insert is accurately positioned in the mold.
Mold Closure
The mold closes, securing the insert in place.
Injection
Thermoplastic material is injected around the insert.
Cooling
The part solidifies under controlled cooling.
Ejection
The molded component is removed from the mold.
Post-Processing
Excess material is trimmed, and the part is inspected.
Forged for ±0.05 mm Geometric Perfection
At PML, we specialize in multi-insert moulding with tight tolerances up to ±0.05 mm, depending on raw material grade and part geometry.
