Cold feed extruder for making rubber blanks

The cold feed rubber preformer is a versatile rubber processing machine integrating multiple functions such as filtering, extrusion, cutting, automated weighing, and counting. Unlike its hot feed counterparts, the cold feed preformer employs a continuous cold feed approach. This innovative approach not only boosts rubber product manufacturing efficiency but also significantly reduces labor intensity.

Our cold feed rubber preformers are available in two distinct structures: one with a gear pump and another without (screw-type). The gear pump structure allows for precision preforming of various rubber materials, ensuring stable extrusion under controlled pressure, and guaranteeing precise blank weight. While the screw-type preformer produces rubber blanks with weight precision closely tied to shape, size, type of rubber, and hardness. This option is ideal for production using standard rubber materials or primary rubber products with less stringent weight accuracy requirements.

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.
Cold feed preformer is a process where rubber compound is directly fed without the need for a milling machine to mill the rubber.

Cold preformer offers several advantages, and some of the key ones include:

  • Continuous feeding
  • No need for preheating with a milling machine
Our company's preforming equipment can handle circular rubber products, rubber seal and rubber strip, 3D rubber part and various complex rubber blanks.
We provide training for rubber equipment operators.
Our company has extensive experience in the design, research, manufacturing, sales, and after-sales service of rubber processing equipment. We provide comprehensive solutions for rubber product manufacturers. To date, rubber product manufacturers from various countries such as Brazil, Thailand, India, the United States, Russia, and South Korea have purchased our rubber equipment and provided positive feedback.
