HDPE Extrusion Coating Production Line

Application of HDPE Extrusion Coating Production Line
This line is designed to process HDPE pellet raw materials through pre-treatment and melt plasticization, then precisely coat the molten HDPE onto the surface of substrates (such as carbon fiber and metal). After shaping, cooling and traction conveying, it continuously produces HDPE-coated composite parts. It realizes substrate protection, ensures uniform, well-adhered and stably formed coating layers, and achieves efficient and continuous mass production.

High Forming Precision: The single-screw extruder ensures uniform melting of raw materials. Combined with special-purpose coating dies, it enables the HDPE layer to feature uniform thickness, tight adhesion and excellent bonding strength with the substrate.
Precise Substrate Positioning: Equipped with a busbar straightener, it can stably correct the conveying state of substrates, prevent deviation and bending, stabilize the coating process and reduce coating errors.
Excellent Shaping Effect: The circulating cooling water enables rapid cooling and shaping, accelerating the hardening speed of the HDPE coating layer and ensuring stable formed dimensions, which guarantees the consistency of the finished products’ appearance and specifications.
Continuous & High Efficiency: The entire process—from raw material feeding to finished product traction—is connected in a fully automated manner. The traction machine provides unified rhythm control, making it suitable for large-batch continuous production with high efficiency.
Wide Applicability: It is compatible with various substrates including carbon fiber and metal, and can complete coating according to preset shapes, meeting the production requirements of different types of composite parts.

Are you a factory or a trading company?
