For use with coating machines coating rods

Solve coating-related issues — such as uneven thickness, defects and material waste — to ensure precise and efficient coating processes.

Coating Rods Design and Manufacturing

By adopting proprietary technology, we lower the friction coefficient between the grooved surface and sizing roller. This reduces the driving torque of the coating rod and prolongs the service life of both sizing bar and sizing roller.

Under the same bar-to-roller pressure, our design optimizes film and paper coating quality and minimizes abnormal wear of the metering rod. Utilizing the inherent properties of coating materials enhances the release performance between coating media and coating bars, effectively lowering groove blockage risks.

We supply grooved coating rods in a full range of specifications tailored to customer production needs, enabling accurate adjustment of coating weight and stable film quality for different application demands.

Applications of HM Coating Rods

We adopt proprietary technology to reduce the friction coefficient between grooved surfaces and sizing rollers.

It lowers driving torque and extends the service life of sizing bars and rollers.

Under identical rod-to-roller pressure, our design optimizes coating film and paper quality.

It also reduces abnormal wear of the metering rod.

We utilize coating material properties to boost release performance between coating media and coating rods.

This prevents groove blockage and guarantees stable coating operation.

Coating Rods Quality and Troubleshooting

Coating rods evenly coat base paper, cardboard and film surfaces.

It ensures consistent layers for subsequent coating procedures.

It enhances paper surface performance and coating uniformity.

It also improves the appearance and printability of coated paper, supporting high-quality paper and film production.

The metering bar coating system includes four core parts: metering bar, coating roller, coating tank and drive control system.
