Anyone with certain social experience may know that many plastic products are produced by injection molding. I have watched a video before, that is, the bathtub we take in a bath is injection molded in one step. In fact, plastic trash cans work the same way. The finished product is molded by one-time injection molding of the abrasive tool, which is seamless, beautiful, simple to operate, and low cost!

So careful people will find that when we buy some plastic trash cans, we may encounter some situations where the price is lower than the market price. These may be some defective products, most of which have air bubbles. This is mainly due to the improper operation of the plastic trash can during injection and some conditions caused by poor craftsmanship. So how to avoid bubbles in the injection molding process? We can look at the beauty created by plastic trash can manufacturers.

In order to solve the bubble problem in the production of plastic trash cans, we need to increase the injection energy, consider the pressure, speed, time and material volume, increase the back pressure, ensure the fullness of the filling mold, increase the smooth flow of the material temperature, and reduce the material temperature and The shrinkage rate, appropriately increase the mold temperature, especially the local mold temperature that forms the vacuum bubble. The gate is set on the thicker part of the workpiece to improve the flow conditions of the nozzle, runner and gate and reduce pressure consumption. Improve mold exhaust conditions. The uneven flow of plastic in the mold keeps air trapped in it.
