Silicone products appear viscose phenomenon how to deal with

There are a lot of process details in the front end of the production of silica gel products, and QC at the back end of the product is also a lot of common detection problems, hot formed product surface adhesive for a lot of silica gel products manufacturers have a headache, then how to professional silica gel products manufacturers to solve?


Problems for the silicone products manufacturer, all kinds of bad is not the reason for the raw material color mixing, molding technology and mould design is reasonable, and the product of stick in the first place in the mold die to find the main reason, in the process of production of silicone products after the vulcanization is introduced two mold mold core need to set aside to thoroughly will flash and raw rubber from the product, because the product inside groove die structure makes it hard for take out the product in the second vulcanization is the groove in the rubber processing clean; Secondly, there is no accurate control of the weight of raw materials during production, so that too much raw glue flows into the mold and there are no cracks in the mold, and the cleaning of the mold after the mold is not clean enough, which leads to the raw glue and the rough edges of the mold. The last important reason is that many silica gel products manufacturers for a large number of products need to catch up with the output, the vulcanization time will reduce the product surface soft, coupled with the structure of the mold, so the emergence of rubber products close to the reason.


How to deal with:
1. Control the precision of the mold in order to make the mold release faster and make the product cleaner.
2. During the production process, in order to achieve the production effect, the product should be cleaned as much as possible before the secondary vulcanization, and the rubber material should be controlled within a certain weight range while the raw materials are placed, so as to reduce the temperature and time in the vulcanization process and avoid the soft phenomenon of the product.
3. You can use a dust-free cloth dipped in stripper water to wipe back and forth. For soft products, you can use a blade to scrape to see if they can be cleaned.
