We offer advanced PCBA Low-Pressure Molding (LPM) solutions, a revolutionary technology that encapsulates and protects sensitive electronic components safely and rapidly using hot-melt materials at extremely low pressures. For projects demanding high efficiency, superior reliability, and ultimate component safety, LPM is the perfect upgrade and alternative to traditional epoxy potting.
The Core Value LPM Brings to Your Product
Our LPM service is designed to provide your product with a comprehensive set of advantages that traditional methods cannot match:
- Protection for Delicate Components: With injection pressures as low as 1.5 bar and low processing temperatures, our process is exceptionally gentle. It will not damage fragile solder joints, inductors, connectors, or sensitive chips, ensuring 100% functional integrity.
- Extreme Production Efficiency: Cycle times measured in seconds mean your product is ready for the next step almost immediately after molding. Compared to the hours-long curing time of traditional potting, LPM can boost your production efficiency by orders of magnitude, significantly shortening your time-to-market.
- Superior Waterproofing & Sealing: The LPM material forms a seamless, molecular-level bond with the component, providing excellent protection against moisture and dust, easily achieving IP67/IP68 ratings.
- Excellent Physical Properties: The encapsulated product exhibits outstanding resistance to vibration, thermal shock (-40°C to 150°C), and chemicals, dramatically enhancing its durability and reliability.
The Advantages of Low-Pressure Molding
We are more than just an LPM service provider; we are your trusted technical partner.
- Expert-Level Mold Design & Manufacturing: Our engineers start with an analysis of your product’s structure, using advanced mold-flow simulation software to design and build high-precision aluminum molds. We optimize the mold’s runners, venting, and cooling systems to ensure uniform material flow, a flawless finish, and maximum production efficiency.
- Precise Material Selection & Application: We maintain a rich library of LPM materials (primarily hot-melt polyamides) and possess a deep understanding of each material’s unique properties regarding adhesion, hardness, flame retardant rating, temperature resistance, and color. We will recommend the most cost-effective and best-performing material for your specific application, whether it’s an automotive sensor or a consumer electronics connector.
- Lean Process Control & Quality Assurance: Our experienced engineering team has an in-depth understanding of the LPM process. We establish the optimal injection temperature, pressure, speed, and cooling time for your project to prevent common defects like flash, air bubbles, short shots, or internal stress.
Our Engagement Process
- Requirement & Product Analysis: You provide the 3D model and technical requirements for your product (PCBA or component).
- Solution & Mold Design: We propose an LPM solution and commence the mold design and manufacturing process.
