Molded & Overmolded Components
Electrical Molded Parts
Precision Injection Molding for High-Performance Electrical Applications
The Impermeable Shield for High-Performance Power
Engineered from high-dielectric polymers, our custom-molded components provide the unbreakable moisture, thermal, and mechanical protection required.
Manufacturing Process
This process delivers precision-molded components with high dielectric strength and mechanical reliability. The process of creating electrical molded parts at PML follows a robust, quality-controlled sequence:
1
Mold Design
Custom molds developed to support complex geometries and insert placement
2
Material Selection
Selection of insulating and, where applicable, conductive materials
3
Insert Placement
Metal inserts placed in-mold for components requiring conductivity
4
Injection Molding
Molten polymer is injected to encapsulate inserts and form the part
5
Cooling
Controlled cooling ensures material integrity and dimensional accuracy
6
Ejection
The solidified part is removed from the mold
7
Post-Processing
Includes trimming, deburring, and quality inspection
Tooling Used
Technical Specification
These tools are critical for repeatability, integration, and quality in molding electrical components.
