Low pressure molding, also known as LPM, is a manufacturing process that involves injecting a fluid (usually a thermoplastic or thermosetting material) into a mold or cavity at a low pressure. Low pressure molding machines are specialized machines that are designed specifically for this process.
Low pressure molding is a relatively new manufacturing process that has gained popularity in recent years due to its ability to produce high-quality parts with a high degree of precision and accuracy. It is especially well-suited for use in the production of small, delicate parts that require a high level of detail and a smooth finish.
Low pressure molding machines typically use a plunger or a screw to inject the fluid into the mold at a low pressure (usually between 10 and 100 psi). The low pressure allows the fluid to flow more easily and smoothly into the mold, which helps to ensure that the parts have a high level of accuracy and detail.
Low pressure molding is a versatile process that can be used to produce a wide range of parts, including electrical components, automotive parts, medical devices, and other products that require a high level of precision and detail. It is an efficient and cost-effective process that offers many benefits, including reduced material waste, high precision, and fast cycle times.
