Low pressure molding
1972 :France IBM first time.
1987 :Eruope automotive start to molding for electronics
1993 :Use for France automotive wiring harness industry
1995 :Wide use for automotive and extended to electronic
2000 :Use for PCB, Sensoring Device and connectors.
After2000: Wide range use for worldwide inudstries.
The low pressure injection molding process is a packaging process that uses a very low injection pressure to inject the encapsulating aterial into the mold and quickly solidation. In order to achieve insulation, temperature resistance, impact resistance, reduce moisture, waterproof, dust, chemical resistance.
Applies to: circuit boards, electronic connectors, wiring harnesses, batteries, switches, LED lights, coils, etc..
