The LSR overmolding injection process, also known as Liquid Silicone Rubber overmolding or two shot molding, is a sophisticated manufacturing technique that involves molding silicone material over a pre-formed substrate or part such as plastic, metal or electronic, which enables the silicone to bond seamlessly with the substrate once cured. This process offers a myriad of benefits, including enhanced product durability, resistance to extreme temperatures, chemical stability, and flexibility. Its professional application in industries such as aerospace, automotive, healthcare, consumer goods, home appliances and electronics allows for the creation of high-quality products that meet stringent industry standards. The precise control of material flow, injection parameters, and curing conditions in LSR overmolding ensures consistent and precise part production while minimizing waste and ensuring cost efficiency. By leveraging the LSR overmolding process, manufacturers can achieve complex geometries, intricate designs, and seamless encapsulation of electronic components, leading to superior product performance and reliability. Overall, the LSR overmolding process stands out as a cutting-edge solution for creating durable, high-precision products across a wide range of industries, showcasing professionalism, innovation, and quality craftsmanship.

The process of liquid injection over molding mainly includes the following steps:

– Mold design and manufacturing: Design and manufacture precision molds according to the shape, size, and performance requirements of the product. The mold material is usually a high hardness, deformation-resistant metal to ensure multiple uses and high precision production.

– Material preparation: Select liquid silicone rubber materials that meet the product requirements, mix and stir according to the formula requirements to ensure material uniformity and stability. Liquid silicone rubber usually needs to be mixed with curing agents, pigments, additives, etc., and degassed to remove air bubbles.

– Injection molding: Inject the mixed liquid silicone rubber into the mold, covering the surface of the preformed substrate such as plastic, metal and electronics. This process requires precise control of injection speed, pressure, and silicone rubber temperature to ensure product consistency and quality.

– Curing: The liquid silicone rubber injected into the mold undergoes a curing reaction under certain time and temperature conditions, forming a stable silicone rubber layer. The curing process determines the physical properties and surface quality of the final product.

– Demolding and post-processing: After curing, remove the silicone rubber product from the mold and carry out post-processing steps such as trimming, cleaning, and surface finishing to achieve the final appearance and performance requirements of the customer.
