  I. What is liquid silicone rubber molding? Liquid silicone rubber (LSR) molding, sometimes called liquid injection molding (LIM), is a thermosetting process in which two compounds are mixed and then heat-cured using a platinum catalyst inside a mold to create flexible silicone parts. Low compression permanent deformation and the ability to resist extreme temperatures make LSR molded pieces durable and ideal for challenging applications. LSR elastomers offer superior optical clarity, durability, and design flexibility while operating over a wide temperature range (-50℃ to 250℃). LSR injection molding is suitable for manufacturing complex geometric shapes, and because of its design and mold flexibility, multiple functional components can be combined into a single part. LIM has considerable advantages in terms of product reliability and total tooling cost. II.How is LSR different from injection molding? LSR molding is very similar to the way traditional injection molded parts are ...

 The reason for affecting the precision of silicone seals ? For products with high precision requirements, it is necessary to function within the range of its tolerance. In the silicone rubber industry, the precision tolerance requirements of products are not very strict. There are often some special silicone rubber electronic parts, silicone rubber precision accessories, and other products that need high precision requirements. So there are some difficulties in the custom processing of silicone rubber products that want to achieve high precision. The primary reason is the horizontal calibration of the machine. The precision silicone manufacturing machines. The size of the silicone products is better, and the deviation of the larger product size is 0.3-0.5mm or so, which is a common phenomenon. The problem of the machine mainly stems from whether the upper and lower bearings are symmetric, whether the template is symmetric and whether the ground is symmetric and other factors! The ...

   Silicone overmolding and doubt shot molding are two silicone molding technologies widely applied in custom silicone products & parts. The two silicone molding technologies are complex and difficult to operate and grasp because they need to obey strict tolerance. Silicone overmolding is done with a normal injection molding machine, and then take out the first forming products, and add another injection molding machine. The Double Shot Molding is completed by a Double color injection Molding machine, a molding that can have two kinds of color effects and different materials. Here, we will discuss double-shot molding and the difference between the two silicone molding and their advantages.   I. Silicone Overmolding   Silicone overmolding is the silicone rubber material forming sheet, and plastic parts, such as tubing and plate shape. In general, the substrate material (the first block to bonding with other materials) is into the injection mold, then coating form...
