Double-sided Single Screw Extrusion Coating Machine

Machine introduction:

The double-sided single screw extrusion coating machine is a specialized machine used to apply a uniform layer of coating material (e.g., polymer, adhesive, or resin) onto both sides of a substrate simultaneously using a single screw extrusion system. This machine is mainly used in the fields of shoe materials, automobile interiors, textiles, garments, and more.

 

Main features:
1.The use of high-precision alloy steel die head, so that the coating effect is more ideal, double-sided coating at the same time to effectively solve the problem of wrinkles caused by the second coating, low efficiency, low-grade products.

2.High Efficiency: Capable of high-speed production.

3.Versatility: Suitable for a wide range of substrates and coatings.

4.Cost-Effective: Reduces material waste and operational costs.

5.Consistent Quality: Delivers high-quality, consistent coatings.

6.Energy Efficiency: Designed to minimize power consumption.

Technical parameter:

Model
Coating Width	200-2000mm
Coatinig Weight	20-200g/m
Coating Speed	250m/min
Unwind Diameter	1000mm
Rewind Diameter	500-1000mm

Advantages

1. High Efficiency & Uniform Coating

Single-screw extrusion system ensures stable melting and even polymer distribution.

Simultaneous double-sided coating improves production speed vs. single-side machines.

2. Cost-Effective Production

Reduces processing steps by coating both sides in one pass, saving time and energy.

Lower material waste due to precise extrusion control.

3. Advanced Control Systems

PLC automation for precise temperature, speed, and thickness adjustments.

Real-time monitoring of coating weight .

4. Compact & Energy-Saving Design

Integrated heating/cooling systems optimize energy use.

Smaller footprint than tandem extrusion lines.
