Waterproofing Electronics
Made Easy with Low Pressure Molding

The Low Pressure Molding (LPM) technology is an innovative procedure for waterproofing electronics, employing thermoplastic hot melt adhesives. This process shapes the material around the electronic components using low pressure and comparatively low temperatures, thus ensuring a water-resistant seal.
In the course of the LPM process, a specialized LPM adhesive resin is used, which is melted in a melting reservoir and then injected into the mold at low pressure. The mold-set, made of stainless steel, securely holds the inserted electronics for encapsulation. With the reduced pressure and low temperature, the adhesive material is gently molded around the electronics, forming a watertight seal without damage.

Waterproof Sealing:

The Low Pressure Molding process ensures a lasting, waterproof seal around electronic components, providing protection against water, dirt, and other environmental influences.

Gentle to Sensitive Components:

Low Pressure Molding ensures sensitive electronic components are treated with care, avoiding damage or deformations due to high temperature and pressure in the molding process.


Fast Process:

Low pressure molding enables swift and efficient waterproof housing production for electronic components, reducing time compared to other techniques like potting, conformal coating, gasket sealing or laser welding.


Enhanced Durability:

Low Pressure Molding creates a durable housing for electronic components, increasing their resilience and longevity in demanding environments.


Low Pressure Molding allows for the shaping of the encapsulant in various forms and sizes, meeting the unique requirements of the electronic components.


Cost Efficiency:

Efficient material use and swift process make Low Pressure Molding cost-effective. It requires fewer materials and can reduce production time.

of Low Pressure Molding

Low Pressure Molding is especially advantageous in fields like automotive, medical, agriculture, telecommunications, white goods, and consumer electronics, where a watertight seal for electronic components is critical. Leveraging the LPM process significantly enhances reliability, protection, and performance in these applications.
