Injection molding machine problems about mold
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 …
Causes of screw wear of vertical injection molding machine
The injection system of the vertical injection molding machine is composed of a plasticizing device and a power transmission device. The injection screw plasticizing device is mainly composed of a feeding device, a barrel, a screw, and a nozzle. The power transmission device includes an injection cylinder, an injection seat moving cylinder and a screw Drive device. The injection screw …
how to choose proper mold and case of die loss
Mold selection Die Material Selection is a very important link in the whole die making process. Die Material Selection needs to meet three principles, die to meet the wear resistance, strength and toughness and other work requirements, die to meet the process requirements, and die should meet the economic applicability. The folding condition requires 1. Wear resistance. When the blank …
injection molding machine of structure:work, advantages (compared with other ones）
Injection molding is an important industrial method. It is somewhat similar to die casting, but the difference lies in the raw materials used. In die casting, the metals we use require extremely high temperatures to melt, but injection molding is mainly performed on glass, elastomers, and the most common thermoplastic and thermosetting polymers, but this technology has been widely used to make thermoplastic materials. The process is completed by heating the raw material and applying pressure at a specific temperature to inject it into the mold cavity without any change in its chemical composition.
How to divide the mold accuracy level
1. Moulds refer to precision forming tools used for batch forming, stamping and other products. The accuracy of the mold includes the accuracy of the parts obtained in processing and the production time guarantee It can prove the quality awareness of product accuracy, but the mold accuracy usually refers to the accuracy of mold working parts. â‘ . The concept of …
Why use baked plastic raw materials?
Why use baked plastic raw materials? ABS, PC, PA6 types of plastic raw materials need to be baked, but PP, TPO, POM types do not need to be baked? In the injection molding process, the moisture content of the material must be in a relatively low range to ensure the normal injection molding and the normal physical properties of the …
China mold industry is growing faster than GDP!
China mold industry is growing faster than GDP! According to the “Basic Situation of National Mould Professional Factory” compiled by the Operation Management Committee of China Mould Industry Association, China’s mould is growing at an average rate of over 15%, which is more than double the average value-added of domestic GDP. Among them, casting molds account for about 5% of …
