Backflush Automatic Hydraulic Screen Changer for Plastic Granulation Production Line

The backflush automatic hydraulic screen changer is an essential core filtration device specially designed for modern plastic granulation production lines, widely used in the processing of recycled plastic particles, new plastic granulation and various extrusion granulation scenarios. Different from traditional manual and semi-automatic screen changers, this hydraulic-driven backflush model solves the core pain points of frequent shutdowns, low efficiency and high material waste that plague trad

Application Scope of Single Plate Hydraulic Screen Changers

Single plate hydraulic screen changers are essential melt filtration equipment in plastic processing, widely applied across multiple industries due to their efficient impurity removal, non-stop operation, and stable performance. Their core function is to filter out contaminants like metal particles, dust, and degraded plastic from molten thermoplastics, ensuring the purity and quality of finished plastic products. In the plastic extrusion sector, they are indispensable for film and sheet product

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
