PU Elastomer Casting Machine for Extrusion Rollers

Product Overview

Specially designed for the production of polyurethane rollers for extrusion industry, widely suitable for extrusion molding equipment such as plastic, rubber and metal plates.

This PU casting machine is purpose-built for manufacturing polyurethane rollers used in extrusion production lines. The 2A2B two-component system includes a dedicated wear-resistant additive tank, compatible with reinforcing fillers to produce rubber layers that are wear-resistant, tear-resistant, and stable under pressure without deformation after long-term extrusion. The system supports flexible switching between MOCA and BDO chain extenders, allowing adjustment of hardness and resilience to suit different material extrusion conditions. Dynamic precise metering and temperature control ensure uniform rubber layer hardness, minimal compression set, and stable operation, guaranteeing the dimensional accuracy of extruded products while avoiding scratches and deformation. With strong adhesion between the rubber layer and the roller core, the machine delivers stable and reliable operation for long-term continuous production, extending roller service life and adapting to high-load continuous operation across various extrusion production lines.

Operation Workflow

Raw Material & Additive Preparation

Prepare CPU prepolymer and chain extender (MOCA or BDO) at the target mix ratio (MOCA: 100:9-12; BDO: 100:3-6); select wear-resistant additives and reinforcing fillers and load them into the dedicated additive tank.

Tank Loading & Temperature Setting

Load prepolymer into Tank A and chain extender into Tank B. Set Tank A temperature to 30–80°C, and Tank B temperature based on the selected formula (MOCA: 90–115°C; BDO: 25–50°C).

Vacuum Defoaming

Activate the vacuum defoaming system to achieve vacuum level ≤-0.095MPa, removing bubbles from all components to ensure dense, pore-free rubber layers with consistent mechanical properties.

Precision Metering, Mixing & Casting

The PLC-controlled dynamic metering system dispenses materials precisely. The mixing head runs at 7000–11000 r/min for homogeneous blending. Pouring rate is adjustable 60–1100 g/s to fit various roller specifications.

Frequently Asked Questions

What extrusion applications is this machine designed for?
This machine is specially designed for producing polyurethane rollers used in extrusion molding equipment for plastic, rubber and metal plates. It is used for material guiding, pressing and conveying, adapting to high-load continuous operation across various extrusion production lines.
How does the machine ensure wear resistance for extrusion rollers?
The 2A2B configuration includes a dedicated wear-resistant additive tank compatible with reinforcing fillers. This produces rubber layers that are wear-resistant and tear-resistant, stable under pressure and not deformed after long-term extrusion, significantly extending roller service life.
How does the machine ensure dimensional accuracy of extruded products?
Dynamic precise metering and temperature control ensure uniform rubber layer hardness and minimal compression set. The stable operation of the rollers helps maintain consistent contact pressure, guaranteeing the dimensional accuracy of extruded products while avoiding scratches and deformation.
Can I adjust the hardness of the produced rollers?
Yes. The machine supports flexible switching between MOCA and BDO chain extenders, allowing you to adjust hardness and resilience to suit different material extrusion conditions and specific application requirements.
How is the adhesion between the rubber layer and the roller core?
The machine ensures strong adhesion between the rubber layer and the roller core, which is critical for long-term continuous production. This strong bond prevents delamination, ensures stable operation, and prolongs the overall service life of the rollers.
What quality certifications does this equipment hold?
Documentation and conformity requirements are reviewed for the selected equipment configuration and destination market. Request the applicable declarations and supporting records for the quoted model. A company quality-management certificate does not certify the equipment or finished-part performance.
