Many people have questions about how the plastic products we usually use, such as water basins, buckets, storage boxes, flower pots, etc., are made. Today I will reveal the secret for you.

Commonly used plastic products, such as mineral water bottles, are blow molded, some small plastic accessories are drip molded, and most of them are injection molded (such as plastic water basins, mobile phone cases, computer cases, and even some handles on cars, etc.). As long as they are thermoplastic materials, most of them can be made with injection molding machines. The injection molding machine is a special plastic molding machine. It uses the thermoplasticity of the plastic. After being heated and melted, it is quickly poured into the mold cavity by a high pressure. After a period of pressure and cooling, it becomes a plastic product of various shapes.

How to make plastic water basin injection mold

First of all, there must be an injection molding machine and a blow molding machine. Specifically, injection molding is to put the raw materials into the injection molding machine, melt them and inject them into the mold to cool and shape, while blow molding first melts the raw materials into a tube blank, and then puts the tube blank into the mold. Compressed air will take shape. Then process or purchase the corresponding molds, purchase the corresponding plastic particles after assembly and debugging, and adjust the color to start work.

Generally it is made of plaster, first use wax to make the look you want, then make a box and put your wax model into it, then pour the plaster, mix it with water and make a small hole at the joint with the wax, and the plaster is shaped after heating, the wax will flow out from the small holes, and then pour high-purity cement into it. After molding, the plaster will be broken and the cement base will be ready.

Find an iron container, put the plastic to be melted into it, heat it, and wait for the plastic to melt, then pour it into the mold (determine the size of the mold and the number of cavities according to the product and the injection molding machine). Design the feeding system. Calculate the dimensions of the cavity and core. Design the ejection method. And design heating-cooling system.
