The Custom LSR Molding Process for Electronics
Step 1: Design and Mold Fabrication
Our engineers collaborate with clients to develop precise CAD models tailored to their electronic component specifications. Custom molds are crafted with high-precision CNC machining and multi-cavity configurations to facilitate high-volume production.
Step 2: Material Selection
Based on the application requirements—such as temperature range, chemical exposure, or biocompatibility—we select the most appropriate LSR formulations. Common options include standard, flame-retardant, and medical-grade silicones.
Step 3: Injection Molding
The liquid silicone is injected into the mold under high pressure, filling all intricate features. The process is conducted at controlled temperatures to ensure uniform curing and dimensional accuracy.
Step 4: Curing and Demolding
Post-injection, the parts are cured in specialized ovens, achieving full vulcanization. The molds are then opened, and finished parts are carefully demolded, inspected, and prepared for quality control.
Step 5: Quality Assurance and Testing
Each batch undergoes rigorous testing—including dimensional verification, electrical insulation tests, and environmental stress assessments—to ensure compliance with industry standards.
Key Considerations for Successful LSR Molding in Electronics
Design Optimization
Draft angles are incorporated to facilitate easy demolding.
Thin-wall designs are optimized for material flow and curing times.
Inclusion of venting features prevents air entrapment.
Material Compatibility
Choosing the right silicone formulation is critical to match electrical, thermal, and mechanical properties required by the application.
Mold Maintenance
Regular mold cleaning and calibration are essential to maintain dimensional accuracy and surface quality, especially in high-volume production.
Regulatory Compliance
Adherence to industry-specific standards such as UL, RoHS, REACH, and ISO ensures product safety and market acceptance.
