Precision Casting for Industrial Rubber Rollers
The HF-CPUE-2A2B casting machine delivers consistent elastomer layers for rubber rollers, with dual-process compatibility and high-output capacity up to 1200 g/s.
This machine is tailored for casting polyurethane rubber rollers used in printing, conveying, papermaking, and machine tools. The 2A2B tank configuration supports MOCA (100:9~12) and BDO (100:3~6) systems, enabling flexible production of rollers with varying hardness, wear resistance, and resilience. Equipped with PLC + touch screen control and recipe storage, it ensures repeatable quality for batch production. The integrated vacuum defoaming and automatic cleaning system minimize downtime and maintain material purity.
How to Produce Rubber Rollers with the Casting Machine
Material Preparation
Preheat A-tank (30~80°C) and B-tank (MOCA: 90~115°C / BDO: 25~50°C). Charge prepolymer and chain extender into respective tanks under vacuum defoaming.
Recipe Setting
Select stored recipe or input new mixing ratio on touch screen. The PLC system automatically calculates and adjusts metering pumps for ≤±0.3% accuracy.
Casting & Curing
Start the mixing head at 6000~10000 r/min, pour the elastomer onto the roller core. The flow rate (80~1200 g/s) is controlled for uniform thickness. Cure according to material system requirements.
Post-Processing
After curing, demold and trim the roller. Use automatic circulation cleaning to purge residual material from the mixing head and lines.

Key Features & Advantages
Engineered for precision, durability, and production flexibility in industrial rubber roller casting.
2A2B Configuration with Additive Tanks
Supports installation of color paste and wear-resistant additive tanks, meeting diverse rubber roller color matching and performance enhancement requirements for different industrial applications.
Dual Chain Extender Compatibility
Compatible with both MOCA and BDO chain extender processes. MOCA formula delivers excellent wear resistance and compression resistance for heavy-load operations, while BDO formula features high resilience for dynamic applications.
High-Precision Metering System
Closed-loop metering achieves accuracy of ≤±0.3%, ensuring uniform rubber layer thickness and consistent mechanical properties that maintain operational precision in printing, conveying, and machine tool applications.
Integrated Vacuum Defoaming
Built-in vacuum defoaming system eliminates entrapped air and bubbles from the polyurethane mixture, delivering dense, compact castings with superior adhesion and resistance to delamination under heavy-load operation.
Stable Medium-Flow Casting
Optimized flow rate range of 80～1200 g/s ensures stable medium-flow casting with uniform rubber layer thickness, supporting high-efficiency mass production with consistent quality from batch to batch.
PLC Multi-Recipe Management
Intuitive touch screen interface with PLC-controlled multi-recipe storage allows quick recall of formulation settings for MOCA, BDO, and color paste combinations, reducing setup time and operator error.
