Because the IC tray has light weight, good toughness, and easy forming. Low cost and other advantages, so in modern industry and IC trays, more and more plastics are used instead of other materials, especially in optical instruments and packaging industries, and the development is particularly rapid. However, due to the requirements of good plasticity, high wear-resistant parts, and good …

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 …

Generally, after using the air-cooled chiller for a long period of time, some problems cannot be avoided. If there is a failure, we should carefully check the operating conditions of the various parts of the injection machine. The main points are to check the refrigeration system, electrical system, air system, and water system. To judge whether their homework is normal, the editor …

injection molding conditions is the important thing for workshop owner to master. Injection molding is an industry with a wide range of knowledge, technology and practice. Plastic raw materials, toners, nozzle materials, molds, injection molding machines, peripheral equipment, fixtures, sprays, various auxiliary materials and packaging materials are used in the injection molding production process, which brings a lot of work to the management …

Injection molding machine basic structure is really important for businessman. According to the requirements of the injection molding process, the injection molding machine is a model with strong mechatronics. It is mainly composed of injection parts, clamping parts, fuselage, hydraulic system, heating system, control system, feeding device, etc. At present, common ear injection devices have single-cylinder type and double-cylinder type. …

The screw fracture temperature is also related, but it is rare, almost all of the screw itself is of poor toughness, or the screw has been used for a long time, refurbish the screw! The injection molding materials are rough. For example, adding GF [glass fiber] to the injection molding materials is the most expensive screw and machine! This injection molding material has poor …

The effect of back pressure on injection molding is very important, and it directly affects the filling of the melt and the quality of the plastic parts.   (1) Proper back pressure can improve the quality of products   ①It can compact the melt in the barrel, increase the density, and improve the injection volume, product weight and dimensional stability;   ②The …

1. Preparations before starting the china injection molding machine 1. Wear the safety protective clothing prescribed by the workshop before starting production. 2. Clean up the environment around the equipment, and don’t store anything unrelated to production. 3. Clean up the debris inside and outside the workbench and equipment, wipe the injection seat guide rail and the tie rod of …

Abstract: The proportion of plastic materials in life is getting higher and higher.And the requirements for its quality are getting higher and higher. As an important production method, injection molding is more and more urgent for the improvement of technology. There are many influencing factors, but the injection molding process conditions are one of the important influencing factors. The following …

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 …

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 …

1: The die must be grinded after a long time use, after grinding the edge surface must be demagnetized, can not have magnetic, otherwise easy to occur blocking material. In order to find out which parts and components have been damaged and the degree of wear, the enterprises should make detailed records and statistics of their use, care (lubrication, cleaning, …
