Detailed introduction

Dalian injection molding plastic products can melt into liquid after the plastic is heated to a certain temperature. The molten liquid is injected into the closed mold cavity with high pressure, cooled and shaped, and ejected after opening the mold to obtain the required plastic products. In injection molding, these elements are interrelated and cannot be set arbitrarily independently. Instead, the relationship between the shape of the formed product, the type of resin and the structure of the mold should be considered and set according to the state of injection molding. And from the strength of molded products, the gate is too small and the strength becomes weak.


Which one is better for Dalian hollow molding? On the contrary, if the gate is too large, there will be excess residual stress around the gate, which is the cause of deformation and crack. Dalian hollow molded plastic products refer to hollow plastic products of various shapes and volumes such as bottles, barrels, cans and boxes in plastic products. This kind of plastic products has the characteristics of light weight, high strength, good sealing, not easy to damage, water and moisture resistance, corrosion resistance and good barrier. It can be used for the packaging of various liquids, powder and granular articles. It is not only beautiful and hygienic, but also convenient for carrying and transportation.


How much is injection molding? The production and molding process of plastic hollow products is: according to the requirements of product material formula, the main raw materials and auxiliary materials are measured separately and mixed together, stirred and mixed evenly by mixer, and then put into extruder or injection molding machine after mixing, plasticizing, extrusion and granulation (powder can also be directly put into powder extruder or injection molding machine), The raw material is plasticized and melted, the molten material is extruded or injected into the parison for molding products through the parison mold, and then the parison is placed in the cavity of the hollow product molding mold.
