Continuous fiber-reinforced high-performance thermoplastic composites have gradually attracted the attention of the composite industry due to their unique advantages such as light weight, high strength, good impact resistance, short molding cycle, secondary molding, and recyclable

1. Case study When a manufacturer makes black masterbatch, carbon black 40%, using EVA wax as a dispersant, some are very brittle when pulling strips, and some are even unbreakable, the judgment is that the carbon

Twin screw extruders are often used in plastic production and processing. In the actual production, twin screw extruders use their own advantages to improve the utilization rate of material resources and reduce the residual amount

The segmentation of the screw and its function The screw is generally divided into 5 sections: intake and conveying section, melting section, mixing section, exhaust section and homogenization section. Screw arrangement segmentation and temperature setting

Today, with advanced technology, cleaning plastic extruders is not a big problem, but how to properly and economically clean plastic extruders and keep the screw and barrel from being damaged is a problem. Today we

Selection of carbon black Carbon black is the most cheap, high-quality and excellent ultraviolet stabilizer. If carbon black particle size is very small (20 nm), the carbon black concentration is generally set at 2.5%+0.5%. According

Screw extruder is the core equipment of plastic forming and blending modification. In the actual blending modification production process, the screws of the extruder are exposed to harsh high pressure and high temperature environment, and

Plastic materials are divided into 1-7 according to the recyclable grade. The higher the number, the better the recyclable grade, not the safer the material. Each plastic container has a number at the bottom (it

The price of ordinary CaCo3 powder is much cheaper than plastic, the addition of  CaCo3 powder will reduce the cost of plastic products. The CaCo3 powder is called filler. At present, The main purpose of adding CaCo3

The mechanical principle of the extruder is to add water or appropriate liquid into the raw powder and stir it continuously, and then extrude the well-mixed material from the porous head or metal mesh with high

In recent years, with the implementation of the “plastic ban”, biodegradable plastics have gradually entered the public’s vision, which is of vital significance for the development of environmental protection packaging industry. At present, there are

Underwater pelletizing system is the most widely used particle granulation system at present. It is mainly composed of drive valve, die head, pelletizer head, water circulation system and pipe fittings, dehydration and drying system, vibration

3D printing metal materials are mainly in the form of powder and wire. Powder materials are the most commonly used materials, which can be used in a variety of 3D printing processes such as Selective

The underwater pelletizing line is generally composed of start-up valve, die head, pelletizer, water bypass system and pipe fittings, centrifugal dehydrator and control system. Underwater pelletizing line is a kind of “Hot-face cutting”. When uniform high-temperature

3D printing technology is an intelligent manufacturing technology that originated in the 1980s and integrates machinery, computer, numerical control and materials. The basic principle of this technology is that according to the two-dimensional section information

Twin screw extruder is used to extrude molten plastic through a fixed shape extrusion mouth under the action of the screw, and cut it after being water-cooling or air-cooling. It is used in the filling, blending,
