Whether the venting screw leaks material is directly related to the extrusion process, plastic properties, and the design of the screw and vent. Therefore, when manufacturers use venting extruders for production and processing, they must have a detailed understanding of the processing technology, resin characteristics, and equipment performance to ensure that the venting extruder can operate normally and stably.

Advances in twin screw extruders offer opportunities for processing that is shear sensitive or limited by torque and/or temperature. Regardless of the formulation and/or end product, it is important for processors to understand and employ the latest technology to achieve success.

Filler masterbatch refers to the granules and powders obtained by mixing and kneading various additives and fillers with a small amount of carrier resin in the process of plastic processing and molding for the convenience of operation. The main component of filler masterbatch is filler, which is mainly used for the processing and molding of polyolefins (polyethylene and polypropylene), and is also called polyolefin filler masterbatch.

The future development trend of PC/ABS alloy will focus on technological innovation, market demand growth, expansion of application areas and performance improvement, and the prospects are broad.

Hot melt adhesive is a plastic adhesive. Its physical state will change with the change of temperature within a certain temperature range. Its chemical properties are non-toxic and odorless, and it is an environmentally friendly chemical.

11 important principles of plastic extrusion 01Mechanical Principle 02Heat principle 03Deceleration principle 04Feed acts as coolant 05In the feeding area, it sticks to the barrel and slides onto the screw 06Materials cost the most 07Energy costs are relatively unimportant 08The pressure at the end of the screw is important 09Output = displacement of the last thread +/- pressure flow and leakage 10 Shear rate plays a major role in viscosity 11The motor and the cylinder are opposite to each other

Extruder screen changer, as the name implies, is a device used in plastic extrusion production lines. Its main function is to filter out impurities and particles in the melt to ensure the purity and consistency of the extruded material. The screen changer contains one or more filters, which can be replaced according to production needs to achieve a continuous filtering effect. In the plastic extrusion process, the presence of the screen changer effectively avoids production line interruptions and product quality problems caused by impurities.

PBAT (polybutylene adipate/terephthalate) is a biodegradable plastic that is widely used in many fields due to its good biodegradability and physical properties.

The basic concept of plastics and the performance characteristics of commonly used engineering plastics.
