Recently, many customers were contacted because of the problem of burrs of silicone rubber products , which caused them some problems, and they found our Yongyong silicone rubber. There are many factors affecting the burr size of silicone rubber products, which have been introduced in previous articles. This issue will share with you a little dry goods, how to control the size of the product's burr.
The first is the mold, mold structure design, demolding method, processing accuracy, and so on are all related to the size of the burr that is produced from the final product.
The second is the molding process. It is necessary to consider which molding process to use in accordance with the product structure, appearance requirements, and order volume, except of course specified by the customer. Generally used is flat pressing, which is suitable for products with simple structure and low burr requirements. The other is that the transfer process is generally suitable for silicone rubber products with high dimensional tolerances and burrs. There is also a type of liquid silicone that mainly competes with high-end precision silicone parts and silicone rubber products, but the cost of the mold is relatively high, and a special liquid silicone injection machine is needed to produce it.
The third molding parameter is mainly the curing temperature, curing time, molding pressure, etc. of silicone rubber products . Of course, all parameters are not absolute, and many times require some experience values!
After the fourth raw edge processing, quite a few companies still use traditional manual trimming. Simple products also use die-cutting. With the development of technology, some of them are slowly being used. Raw edges have their own advantages.
