Injection moulding is a manufacturing process widely used for producing parts by injecting molten material into a mould. It is a highly versatile technique that can be applied to a variety of materials, including plastics, metals (known as die-casting), and glasses. This process is favoured for its ability to produce high volumes of identical items […]

What are the advantages of hot runner molds? What is a hot runner? Hot runner technology is an advanced technology applied to the pouring runner system of plastic injection hot runner molds, and is a hot direction in the development of plastic injection molding technology. The so-called hot runner molding means that the plastic sent

Structure and working principle: Vertical injection molding machine: The injection device and the clamping device are on the same vertical center line, and the mold opens and closes in the vertical direction. This design occupies a small area and is suitable for occasions with limited space.Horizontal injection molding machine: The injection device and the clamping

What is Plastic Molding? In short, plastic molding is the manufacturing process of various plastic parts. Through different plastic molding techniques, plastics can be made into plastic products with various shapes, sizes, and functions, such as: common plastic chairs, plastic cups, plastic trash cans and other daily necessities in life, so that they can be

Nylon products are strong and wear-resistant. They will fade if left outside for a long time. When ignited with an open flame, the flame is blue with a yellow tip. It burns slowly and drips like a candle. It emits a pungent odor when burning. In order to meet the requirements of the product, it

The plastic skin formed on the mold wall reduces the cross-sectional area of ​​the plastic flow, resulting in a pressure drop. There is a maximum limit to the pressure that can be obtained on the injection molding machine to push the screw at the set injection speed. The pressure required to push the screw forward

Do you know the 10 factors that affect the quality of injection molds? Mold manufacturing is a complex process, from design, processing, assembly, debugging and other steps to the final actual use. In the entire life cycle, the factors that affect the quality of the mold are mainly the following 10 aspects. Steel is the

Color difference is a common defect in injection molding. There are many factors affecting color difference, including raw material resin, masterbatch, mixing of masterbatch with raw material, injection molding process, injection molding machine, etc. In the actual production process, we generally control color difference from the following five aspects. Choose an injection molding machine with

As the plastic flows through the injection molding machine and different parts of the mold, there is a loss of pressure on the plastic flow front due to drag and friction. In addition, as the plastic contacts the mold wall, it begins to cool, increasing the viscosity of the plastic and requiring additional pressure to

1) Viscosity curve The purpose of making a viscosity curve is to select a suitable injection speed injection molding process . When there are slight fluctuations in various parameters, it will not cause a large change in melt viscosity. The fluctuation between each mold should be as small as possible to ensure the repeatability of
