Foaming Extruder Production Line
This Foaming Extruder is a high-efficiency device specifically designed for producing foam materials. Through precise extrusion processes, it mixes plastic raw materials with foaming agents to create lightweight, high-strength foam products with excellent thermal insulation and soundproofing properties. Widely used in construction, packaging, automotive, and electronics industries, the machine produces various foam pipes, sheets, and profiles. By controlling temperature, pressure, and foaming agent ratios, it ensures uniform foaming effects and stable product quality. Common foam materials include polystyrene (PS), polyurethane (PU), and polyethylene (PE), which excel in thermal insulation, shock absorption, and noise reduction. These materials are widely applied in insulation pipes, packaging, automotive interiors, and building walls. With its efficient and eco-friendly production, the foam extruder has become indispensable in modern manufacturing, meeting the growing demand for lightweight, high-performance products.

Production Process
Production Line Composition
The extruder main unit is the core of the production line, responsible for efficiently plasticizing and extruding raw materials to ensure tubing quality and production efficiency. It features a high-precision screw and barrel design, paired with an advanced multi-zone temperature control system to guarantee stability and uniformity during extrusion. Driven by a powerful motor, the unit enables continuous, high-efficiency production and adapts to tubing of various specifications.
The cooling system is a critical component of the line, rapidly cooling and shaping extruded tubing to ensure dimensional stability and surface quality. It consists of stainless steel cooling water tanks and a precision-controlled cooling circulation unit.
This system ensures stable pulling of the tubing from the cooling tank at a constant speed, maintaining dimensional accuracy and consistency. Equipped with multiple traction belts or pulleys and a precise speed control system, it accommodates tubing of varying specifications and wall thicknesses.
These final stages ensure seamless transition from production to packaging:
- Cutting System: Precisely cuts continuous tubing into preset lengths using high-accuracy blades.
- Collection System: Automatically coils or stacks cut tubing for organized storage and transport.
Product Introduction
Technical Background
Foaming extruders are pivotal in polymer processing for producing lightweight, closed/open-cell foam products (e.g., XPS insulation boards, EVA foam). The technology utilizes physical/chemical foaming agents injected into polymer melts under high pressure. Recent advancements focus on optimizing foam ratio, cell uniformity, and eco-friendliness:
- Twin-stage screw designs and dynamic mixing elements enhance melt homogenization.
- Multi-stage vacuum degassing controls foaming agent concentration.
- Precision temperature control (±1°C) and mold flow simulation improve dimensional stability.
- Supercritical CO₂ foaming replaces traditional agents, reducing emissions while enabling microcellular foams (<50μm pores).
- Smart control systems with adaptive algorithms adjust screw speed and foaming agent injection in real time for high-end applications in construction and automotive industries.
