Injection molding, also known as injection molding, is a molding method that combines injection and molding. The advantages of injection molding method are fast production speed, high efficiency, operation can be automated, variety of designs and colors, shapes can be from simple to complex, sizes can be from large to small, and the product size is accurate, the product is …

Today let us talk about the principle, characteristics, application and process of injection molding by injection molding machine. 1. The principle of injection molding. Add granular or powdered plastic into the hopper of the injection machine. The plastic is heated and melted in the injection machine to keep it flowing, and then injected into a closed mold under a certain …

There are always problems with the injection part of the injection molding machine, how to solve it? 1. Cannot shoot glue Approach: 1) The nozzle is blocked by foreign matter. Check whether the nozzle is blocked, clean or replace the nozzle. 2) The glue nozzle is broken. Disassemble the flange to check whether the glue nozzle is broken, and replace …

When using an injection molding machine, the possible failures of the hydraulic system of the injection molding machine are diverse. It is the result of a combination of many factors, and the dispersion is relatively large. Therefore, when performing fault diagnosis, it is necessary to analyze the factors that cause the fault one by one, pay attention to their internal …

When we choose a injection molding machine,we have to face the situations of mold repair,thus let us talk about it! (1) When the single parting surface injection mold is opened, the movable mold and the fixed mold are separated to take out the plastic part, which is called a single parting surface mold, also called a double-plate mold. It is …

Knowledge sharing of injection mold hot runner technology in injection molding machine Hot runner gating system can be understood as an extension of injection molding machinery. The function of the hot runner system is to deliver the thermoplastic melt to the vicinity of the molding die or directly into the die adiabatically. The hot runner can be heated independently, but …

There are two templates on the injection molding machine, one is not moving, called the fixed template; the other can be moved, called the moving template. The mold is fixed on the two templates by screws and pressing plates respectively. When the mold is opened, the movable template of the injection molding machine moves, thereby driving the mold to open. …

In the production of injection molding parts, it is inevitable to use plastic raw materials. Today we will explain the production process of pe, the world’s main 11 types of polyethylene PE production technology At present, there are many companies with polyethylene technology in the world, including 7 companies with LDPE technology, 10 companies with LDPE and full-density technology, and …

Anyone who can adjust the machine knows the five elements of injection molding, but on whom are these five elements built? The most important thing is the injection molding machine. Of course, there are also some auxiliary equipment (such as mold temperature controller, temperature control box, etc.) to help complete it. So how much can you know about the performance …

As a injection molding machine,it will face many problems about mold. What does mold EDM mean Mold EDM is EDM. Electric discharge machining is a special machining method that uses the electric erosion effect generated by the pulse discharge between the two electrodes immersed in the working fluid to abate conductive materials. It is also called electric discharge machining or …

How does the injection molding machine screw unusual sound slip to do If the screw begins to slip during the preforming phase, the axial motion of the screw stops as the screw continues to rotate. Usually the screw slip will lead to degradation of materials before injection molding.but also short shot, extended processing cycle and other product quality problems. Influence …

Calculation of Cooling Time of Plastic Injection Molded Parts. As a injection molding machine,in injection production, the cooling time of plastic injection molded parts accounts for about 80% of the entire injection production cycle. Poor cooling often results in product warpage or surface defects, which affects the dimensional stability of the product. Reasonable arrangement of injection, holding pressure and cooling …
