The molded silicone product is obtained by uniformly mixing the raw materials into a mixing rubber through a kneading machine, transferring the mold into a vulcanization molding machine, and then pressing the mold to form, solidify or vulcanize, and then releasing the mold to obtain a silica gel product, but Some defects in the process itself often cause some problems, which is worthy of our attention.

Molded silicone products problem:
1, foaming. Silicone products custom company introduced mold material curing is not complete, the mold temperature is too high, so that a certain component of the material vaporized or decomposed, improve the mold temperature or extend the holding time, reduce the mold temperature.

2, lack of materials. The mold matching gap is too large or the overflow hole is too large, the amount of the release agent is too much, the operation is too slow or too fast, the mold tolerance and the size of the overflow hole are adjusted, and the appropriate mold clamping temperature and pressurization timing are adjusted.

3, molded silicone products problem: burnt. The air is trapped in the billet, and after being compressed, the temperature is raised to decompose the resin, and an effective deflation operation is employed to extend the mold closing time and appropriately reduce the mold temperature.

4, warping. The curing is incomplete, the mold release process is improper, the material shrinkage rate is too large, the curing conditions are improved, and the mold is redesigned to make the ejection device reasonable. Try to release the mold after cooling evenly. Use a shrink holder (shaper).

5, sticking mold. The surface of the mold is rough, the mold temperature is adjusted, the mold temperature is generally lowered appropriately, and the mold release surface is improved by using a suitable mold release agent. The mold should be chrome-plated, the mold material is not added with the mold release agent or improperly added, the mold surface is rough or the new mold is not ground. Use, the pressing pressure is too high, by adding an appropriate amount of effective internal release agent to improve the surface finish of the mold, and then pressing the FRP with the compression molding powder, and appropriately reducing the pressure.

Silicone Products Customized Company Introduction Molded silicone products are currently the most widely used in the silicone industry. Mainly used for only silicone industrial accessories, buttons, silicone gifts, silicone bracelets, silicone watches, key cases, mobile phone sets, silicone kitchen utensils, silicone pads, ice trays, cake molds and so on.
