What are the difficulties in the encapsulation process of hardware silicone products?personalized silicone pacifier clip Processor

　　In the silicone product industry, in terms of the complexity of the process and the accuracy of the product, is it because the two-color process and the encapsulation process are a bit complicated, labor is consumed in the production process of silicone products manufacturers, and the defect rate is not well controlled. Phenomenon, we are also more common in the market, and the products of this process are also more popular in the market, and the more popular products are in the production and processing process for a longer time, so it is similar to silicone spoons, silicone spatulas, etc. All silicone encapsulation process products are simple and clear, but when it comes to the difficulties in the process, compared to many friends, they are confused. How much do you know about silicone encapsulated hardware or PV and other materials?

　　Hardware lagging is to use silicone rubber to wrap the hardware or partially wrap it for high-temperature vulcanization. During the whole vulcanization process, the offset phenomenon of other parts except the silicone part is the most difficult to control. Nylon and other products need to do positioning standards, the general positioning of the seat can be divided into several methods to do.

　　1. When the mold structure is complex, three-layer templates can be opened. Now, vulcanize the rubber material at the bottom of the silicone and the seat where the hardware is placed in the middle mold to form a positioning groove for the hardware. After the hardware is placed inside, the middle layer template is finally removed. After that, the effect of internal hardware package can be achieved, but this method of redundant small products is not feasible! Usually it is a method that can be used for larger products,

　　2. For the double-layer board, if there is no requirement for the appearance, you can choose to add several positioning pins in the middle of the mold, and put the hardware in the positioning of the last layer of rubber and Template, the product will not appear offset, this method can be used for relatively long or round hardware.

　　3. The hardware is relatively small, and the margin of the silicone part is relatively large, so it is possible to directly wrap the hardware by hand for direct molding. This method is not easy for the hardware to be offset and positioned well for products.

　　Generally speaking, the offset leakage of hardware is the biggest difficulty of hardware encapsulation products. Generally, we can solve and improve it in several ways. Excessive pressure on the machine may lead to the phenomenon of hardware offset. When you need to focus on control! The temperature is controlled within a certain range, etc. In short, there are many difficulties in any process for silicone rubber products, depending on how you control it!
