About the Operation of Injection Molding Machine Tips for injection molding machine operation Before booting Check whether there is water or oil in the electrical control box. If the electrical appliance is damp, do not turn it on. Maintenance personnel should dry the electrical parts before turning it on. Check whether the power supply voltage … Read more
Injection Compression Molding Technology What is the injection compression molding technology? Injection compression molding (icm) is an advanced form of traditional injection molding. It can increase the injection length/wall thickness ratio of injection molded parts. And it can use smaller clamping force and injection pressure. Besides, it will reduce material internal stress and improve processing productivity. Injection … Read more
How to Deal with the Vibration and Noise of Hydraulic System? Reasons for the vibration of hydraulic system Vibration and noise of hydraulic equipment mainly come from the mechanical transmission part and the hydraulic system itself. Generally, the inspector can preliminarily judge the part where the vibration and noise occur by ear-listening. The main reason … Read more

And the most basic are the factors of plastic materials, injection molds, injection molding processes and injection molding equipment. In the early designing plastic products, first select the necessary engineering plastics according to the environment. … Read more
About the Five General Plastics Plastic is a polymer compound that is polymerized by addition polymerization or polycondensation reaction with monomer as raw material. It is commonly known as plastic or resin. The composition and shape can be changed freely. It is composed of synthetic resin and fillers, plasticizers, stabilizers, and lubricants pigment and other additives. … Read more
The Reasons of the Demoulding Difficulty of Plastic Injection Mold After the plastic part is injection molded, the plastic part is ejected from the mold cavity. Whether it is a single or multi-element ejection mechanism, the demolding work is generally completed at one time. But sometimes due to the special shape of the plastic part … Read more
