XPS Extrusion Equipment for XPS Foam Board Production

GreenEarth supplies advanced XPS extrusion equipment for manufacturing high‑performance extruded polystyrene (XPS) foam boards with controllable density, fine cell structure and high compressive strength. Our production system integrates raw‑material conveying, high‑torque twin‑screw extrusion, CO₂ foaming, cooling extrusion, board forming, cutting and finishing processes to deliver a complete manufacturing solution.

GreenEarth boasts project experience dating back to 2008 and has delivered more than 200 XPS production lines worldwide. We provide equipment configuration, process optimization, installation, training and after‑sales technical support for manufacturers, thermal‑insulation material producers and industrial investors.

XPS Extrusion Equipment Models and Output Capacity

GreenEarth offers a wide range of equipment configurations to meet diverse production requirements. The suitable model can be selected according to target output, board specifications, product density and plant‑site demands.

Models	Output Capacity
GE75-200	700kg/h
GE95-250	900kg/h
GE110-300	1300kg/h
GE135-400	2,000 kg/h
GE150-500	2400kg/h

Equipment configurations can be customized according to the required output capacity and XPS board specifications. GreenEarth can also supply complete XPS board production lines covering extrusion, cooling, cutting, milling, stacking, packaging and recycling.

Advanced Technologies for XPS Foam Board Production

Automatic Proportioning & Feeding System

A stable supply of raw materials is critical to guaranteeing XPS board quality. GreenEarth adopts automatic proportioning and loss‑in‑weight feeding technology to achieve precise and continuous raw‑material metering.

The digital formula management system allows adjustments to production parameters. The integrated vacuum conveying system can be configured to match plant layout and material‑circulation requirements, helping maintain an orderly and clean production environment.

High‑Torque Twin‑Screw Extruder

The twin‑screw extrusion system delivers efficient material mixing, plasticization and dispersion before foaming. GreenEarth’s high‑torque reducer reaches a specific torque coefficient of up to 10.3 N·m/cm³, compared with approximately 4.9 N·m/cm³ for conventional systems.

Higher torque capacity helps lower material temperature inside the barrel, enables efficient additive dispersion and ensures stable processing of high‑performance XPS formulations.

Fully CNC‑machined barrel and screw elements ensure precise fitting between the screw and barrel, resulting in consistent material dispersion and controlled residence time.

High‑Efficiency Cooling Single‑Screw Extruder

Accurate temperature control is essential during XPS foaming and forming. GreenEarth‑cooled single‑screw extruders adopt an optimized cooling barrel and screw structure to improve heat transfer and melt‑temperature regulation.

The latest cooling structure provides up to 80% higher cooling efficiency than conventional designs, while the optimized secondary extrusion system can reduce energy consumption by approximately 30%.

Active melt sealing technology also helps prevent material leakage and reduces the need for frequent packing replacement.

CO₂ Foaming Agent Injection System

CO₂ foaming requires accurate control of temperature, pressure and injection volume because the physical properties of CO₂ change significantly under different processing conditions.

GreenEarth's foaming agent injection system coordinates CO₂ temperature, pressure and mass flow to maintain stable foaming conditions. A multi-agent injection configuration can also support different product grades and production requirements.

This technology enables manufacturers to produce XPS boards with fine cellular structures while reducing dependence on conventional fluorinated blowing agents.

DCS Intelligent Control System

The intelligent DCS control system integrates production data, formulation records, operating parameters and equipment alarms into a centralized platform.

Operators can manage production formulas, monitor operating conditions and review historical data through the control system. Maintenance reminders generated from alarm and service records can also support equipment maintenance and troubleshooting.

Remote technical diagnosis can further improve after-sales support and reduce downtime during production.

Complete XPS Production Equipment

A complete XPS manufacturing system requires more than the primary extrusion units. GreenEarth integrates auxiliary equipment into the production line to create a coordinated manufacturing process.

The complete equipment configuration can include:

Automatic vacuum raw material conveying
Loss-in-weight and gain-in-weight feeding systems
Twin-screw extrusion system
Cooling single-screw extruder
CO₂ foaming injection system
Edge trimming and grooving equipment
Double-blade and triple-blade cross cutting
Cooling turnover racks
Four-side precision milling
Automatic stacking
Automatic packaging
Online recycling pelletizing
Central dust removal
Laboratory testing equipment

These systems can be configured according to production capacity, board dimensions, factory layout and automation requirements.

For projects involving multiple types of polymer processing, GreenEarth also provides industrial polymer production equipment for different extrusion and processing applications.
