How to Achieve Zero-Leakage Filtration Using Batte High-Pressure Hydraulic Screen Changer

Polymer extrusion of PA12 and PET poses severe challenges to traditional screen changers. Both materials feature high melt viscosity and generate frequent pressure spikes during continuous production. Sudden pressure surges can easily break ordinary seal structures, leading to melt leakage, material waste, product defects and potential safety hazards. Conventional single-cylinder screen changers rely on simple rubber sealing rings, which deform under fluctuating high pressure. Every time operato

PET Extrusion Screen Changer: A Key Component for High-Quality Production

The PET extrusion screen changer is an indispensable device in plastic extrusion lines, especially for polyethylene terephthalate (PET) processing, including sheet, strap, bottle preform and pellet production. Its core function is to filter impurities from molten PET, such as unmelted raw material particles, metal fragments, carbon deposits and gels, ensuring the purity and consistency of the final product. There are two main types of screen changers widely used in PET extrusion: manual screen c

Single-Column Hydraulic Screen Changer for PC Corrugated Extrusion Production Line

PC corrugated sheets are widely favored in packaging, construction, and industrial fields for their excellent impact resistance, light weight, and weather resistance. In PC corrugated extrusion production, melt filtration stability directly determines sheet surface smoothness, thickness uniformity, and finished product yield. As a professional core auxiliary device, the single-column hydraulic screen changer has become the preferred filtration solution for high-efficiency PC corrugated extrusion

Column type hydraulic screen changer

Column type screen changer is a core filtration equipment suitable for continuous extrusion production of polymer materials, with different application scenarios focusing on different subdivision types: 1、 Single column type screen changer scene This type of equipment has a compact structure, high cost-effectiveness, and is suitable for conventional production lines with moderate tolerance for pressure fluctuations. It can be used in scenarios such as plastic granulation, pipe extrusion, ordinar

What Are the Benefits of a Single-Column Screen Changer?

As a classic type of column-style screen changer, the single-column screen changer is an indispensable core filtration device in polymer extrusion production lines. Thanks to its ingenious design and stable performance, it has become a cost-effective choice for small and medium-sized extrusion production lines. Its core structural characteristics and performance advantages can be broken down into two main aspects: I. Robust Materials, Suited for Demanding Extrusion Conditions The main body of th
