Cold feed extruder with gear pump for the continuous production of rubber blanks

Our gear pump rubber preformers combine the plasticizing characteristics of cold feed screw extruders with the stability of gear pumps. The integration of these technologies ensures a continuous and stable material supply to the cutting system, regardless of variations in material or feed pressure. This results in enhanced cutting accuracy and consistent quality of rubber preforms throughout the production process.

Compared to traditional rubber preformers, our gear pump cold feed extruders offer uninterrupted rubber production and high capacity, and eliminate the need for preheating rubber on the open mill. This design offers high performance as well as user-friendly operation and labor-saving advantages.

We are a rubber machinery manufacturer. We primarily manufacture equipment such as rubber preformer machines, ram extruders, rubber blank manufacturing equipment, rubber strainers, rubber cooling conveyor systems, and more.
A gear pump in an extruder optimizes the extrusion process of thermoplastic plastics and polymers. It generates a constant pressure and ensures a consistent extrusion of materials, thus relieving pressure buildup in plastic or rubber extruders.

Rubber extrusion is a process used to manufacture rubber products. This process involves using an extruder with various shaping dies to form primary rubber products of different shapes under high pressure.

In hot feed preforming, the rubber strip fed into the machine must be preheated and plasticized on a rubber mill before processing.
In cold feed preforming, the rubber strip does not require heating and is directly fed into the extruder.

We offer a default 12-month warranty service, and even after the warranty period, we continue to provide discounted technical support and rubber machine parts for our rubber machinery.
We provide training for rubber equipment operators.
