What is Low Pressure Injection Molding?
Low pressure injection molding is a manufacturing technique that involves injecting thermoplastic materials into a mold under controlled low pressure. This technology is particularly beneficial for encapsulating electronic components, where traditional potting methods often fall short. The low pressure ensures minimal stress on the components, preserving their integrity while providing a robust protective layer.
Advantages of Low Pressure Injection Molding
1. Reduced Material Usage
Low pressure molding allows for precise material application, significantly reducing waste. The innovative materials used, such as those from LPMS USA, are designed to wrap around components, allowing for a minimum thickness while still achieving optimal protection. This results in cost savings and environmental benefits.
2. Enhanced Performance
The low pressure injection method enables the use of thermoplastics derived from plant-based fatty acids, which are both REACH and RoHS compliant. This eco-friendly approach not only meets regulatory standards but also provides excellent mechanical properties like UV resistance and thermal stability.
3. Process Efficiency
With customizable machines, such as those offered by www.lpms-usa.com, production processes can be tailored to specific requirements, enhancing throughput. Features like programmable ejection systems and multi-language PLCs make operation smooth and user-friendly.
