Theoretical knowledge of injection molding machine screw: The screw is a key component of the plasticized part, and it is in direct contact with the plastic. The effective length of the plastic passing through the screw groove passes through a long thermal history and undergoes a three-state (glass state, viscoelastic state, and viscous fluid state). The screw The length, geometry, …

Our traditional injection molding industry has also used injection molding machine manipulators instead of manual operations to reduce labor, ensure product quality, improve production efficiency, reduce production costs, and enhance corporate competitiveness. The four major points of management, safety, quality and efficiency of manipulators used in the injection molding industry are summarized as follows: To 一、Management To 1. Use the injection molding …

With the development of industry 4.0 intelligence, manipulators are widely used in traditional industries. As one of the injection manipulators, it is widely used in various injection molding industries, bringing standardized management, high safety，and Stabilizing product quality, reducing scrap rate, improving production efficiency and other advantages, thereby reducing enterprise production costs and enhancing enterprise competitiveness, etc. play an extremely important …

Plastic extruder is a kind of common plastic machinery and equipment. In the process of daily operation of extruder, it is inevitable that various failures will occur, which will affect the normal production of extruder. Below we will detail the failures of extruder Analysis. The main motor cannot start Cause: (1) There is an error in the driving procedure. To …

Generally speaking, most of the customers who have been engaged in the injection molding industry for many years have the ability to judge by themselves and choose the appropriate injection molding machine to produce. However, in some cases, the customer may need the assistance of the manufacturer to decide which injection molding machine to use, or even the customer may only have the …

How to clean the plastic extruder correctly and economically without damage to the screw and barrel, I have compiled some methods for you to clean the plastic extruder correctly, let’s take a look. How to clean the screw properly 1Select the correct heating device Burning or roasting to remove the plastic solid on the screw is the most common and …

The operation and maintenance of the injection molding machine is dangerous, so professionals must be required to operate it When using the injection molding machine, you must pay attention to the safety of the operation. Please check the safety of the machine, the safety of the ejector rod and the reliability of the safety door at the beginning of each …

Injection mold should be designed of  exhaust groove and is a tool for producing plastic products; it is also a tool for giving plastic products a complete structure and precise dimensions. Injection molding is a processing method used in the mass production of some complex-shaped parts. Specifically, it refers to the high-pressure injection of the plastic melted by heat into …

Setting of injection mold temperature Mold temperature affects the molding cycle and molding quality. In actual operation, it is set from the lowest appropriate mold temperature of the material used, and then adjusted to a higher level according to the quality condition. ·   To put it right, mold temperature refers to the temperature of the cavity surface when molding …

The plastic wall thickness  processing has a great influence on quality. If the wall thickness is too small, the flow resistance is large, and it is difficult for large and complex plastic parts to fill the cavity. The minimum size of the processed wall thickness of plastic parts should meet the following requirements: Have sufficient strength and rigidity; It can withstand …

Introduction Compared with ordinary runner molds, hot runner molds have significant advantages such as time-saving, material-saving, high efficiency, and stable quality. However, it was once easy to cause failures in use, which affected its wide application. With the technological progress of the mold industry, hot runner molding has made great progress in runner melt temperature control, structural reliability, and hot runner …
