Mesh belt type hydraulic screen changer

The mesh belt-type fully automatic screen changer is a critical piece of equipment used in plastic extrusion, film production, and other fields to filter impurities from molten materials. Its core feature is the continuous circulation of the mesh belt structure, enabling non-stop automatic screen changes while balancing high-efficiency production with precision filtration requirements. 1. Maintains stable material flow pressure during screen changes, preventing film thickness variations or optic

Core Structure and Functions of Manual Screen Changers

1. Frame: The Foundation Frame for Stable Support As the primary load-bearing component, the frame is constructed from high-strength materials (such as carbon steel or alloy steel). It possesses sufficient rigidity and durability to securely anchor the screen changer body, ensuring no deformation occurs under manual operation or extrusion pressure. This provides fundamental support for the stable operation of the entire equipment. 2. Filter Screen: The Core Barrier for Impurity Filtration The fi

What is a Screen Changer? A Must-Know for Plastic Processors! Simply put, a screen changer is the cleaning expert of plastic extrusion production lines. Its primarily installed between the extruder and the die, filtering impurities and carbonized particles from the melt to ensure material purity. After all, plastic raw materials may contain dust or metal shavings, and processing can generate carbon particles. If these enter the mold, they can cause product defects or even damage equipment.

Blown Film ExtruderScreen Changer

The blown film screen changer serves as the core filtration equipment in blown film production. Its primary function is to filter impurities from the melt through screens, ensuring film quality, while enhancing production continuity through non-stop screen changing technology. I. Working Principle and Structural Types Dual-Column/Dual-Plate Screen Changer Structure: Features a dual-channel, dual-station design where two screens operate simultaneously (one active, one standby).

Analysis of Screen Changers for Plastic Sheet Extrusion

I. Core Functions and Value Impurity Filtration and Product Purity Assurance Screen changers intercept impurities such as metal debris, scorched material, and unplasticized particles within the plastic melt through built-in filters, ensuring pure melt enters the extrusion die. For instance, in medical tubing and food packaging film production, impurity filtration prevents defects like black spots and crystalline inclusions, elevating hygiene standards. Enhanced Production Continuity Non-stop Scr
