Silicone rubber products believe that everyone is no stranger, but do you understand the hardware package silicone rubber? Today, let's talk about the process of silicone rubber packaging silicone rubber products, the main one is the packaging process of silicone rubber and plastic, and the packaging process of silicone rubber and hardware:
The silicone rubber coated products we say are not the kind of parts that are ready to be coated with silicone rubber products and then assembled together, but the plastic or hardware is made first, and then placed into the silicone rubber mold to position it, and then into the silicone rubber material for secondary molding. Compared with the general glue, or set together, it has the advantages of high dimensional accuracy, firm combination and no falling off.
There is also a liquid silicone encapsulation process, commonly known as LSR. Similar to plastic wrap, but this only applies to silicone wrap. This process cost is high, the mold cost is also high, generally used for large quantities, high precision silicone coated products.
Whether it is silicone or rubber in combination with hardware, such as stainless steel, aluminum alloy materials, etc., need to pay special attention to the surface treatment of hardware, if necessary, need to be degreased. This is related to the adhesion of silicone rubber and hardware, and the hot vulcanized glue selected for different silicone rubber materials is not the same.
