Advantageous features of continuous non-stop screen changer

1、Smaller fluctuation of material flow pressure in the process of screen changing, which can ensure the continuous and stable production of products. 2、Equipped with filter plate preheating work and exhaust structure, material pressure, material flow, material temperature balance transition during screen changing, especially suitable for high transparent and high precision products. 3、To achieve no leakage of material, no film breakage, no thread breakage, no fluctuation, no downtime to change t

Is it necessary to install a screen changer on a plastic film extrusion line?

The installation of screen changers (melt filters) is necessary in plastic film extrusion lines, especially in scenarios with high product quality requirements, long continuous production times or the use of recycled materials. The following is a specific analysis: 1. Why is it necessary to install a screen changer? (1) Core functions Filtering impurities: removing carbonized particles, metal shavings, gels, etc. from the melt (to avoid defects such as fish eyes and crystal spots in the film). P

Application Scope of Manual Screen Changers

The application scope of manual extrusion screen changers is relatively broad, primarily concentrated in high-viscosity melt extrusion production scenarios across various industries. By manually switching filter screens to remove impurities, they ensure production continuity and product quality. Below are their specific applications: 1. Plastic Processing Industry Plastic Extrusion Molding Film Production: In the manufacturing of cast films (CPP/CPE) and blown films (PE/PP), manual screen change

Plastic extrusion screen changer for extruder

Screen changer is widely used in plastics, rubber, chemical fiber, coating, ink, adhesive and other industries, and plays a key role in the production process of extrusion, injection molding, blown film, wire drawing and so on. It can filter the impurities in the materials, ensure the continuous and stable operation of the production line, and improve the purity and quality of the products. In the process of plastic extrusion, rubber vulcanization, chemical fiber spinning, etc., the screen chang

Extruder and screen changer matching principle

The principle of matching the extruder to the screen changer is based on the following aspects: Extruder type and model: Single-screw extruders differ from twin-screw extruders in their structure and working principle, so the type and configuration of screen changer required will also differ. The type of extruder determines its production capacity, which in turn affects the filter area and filtration accuracy of the screen changer. Throughput and filtration requirements: Extruder throughput dete
