Pbear has made a breakthrough in fully automatic rubber injection molding. By fully automatic, we mean automatic dosing, preheating, injection molding, automatic dismantling and mold opening can be achieved by simply placing the rubber strip into the feeder. This greatly improves production efficiency and saves labor and material costs.

As a leading automatic rubber injection molding manufacturer in China, our company has more than 30 years of experience in the rubber injection molding machine industry. We have a unique and innovative ability to lead the industry worldwide!

FIFO Rubber Injiection Machine Applicaiton

The Pbear vertical rubber injection molding machine is our best-selling and most widely used model. Equipped with a vertical clamping system and a FILO vertical injection system, it is suitable for most rubber molded products in the automotive, energy, rail transportation, industrial, medical, and household appliance sectors. This rubber molding machine is suitable for a variety of rubber compounds, including NR, NBR, EPDM, SBR, HNBR, FKM, SILICONE, ACM, and AEM.

rubber injection machine manufacturing

1. This rubber injection molding machine consists of a four-column clamping mechanism and injection mechanism, ensuring ultra-stable injection force.
2. The optimized injection rod significantly reduces glue leakage, making maintenance and glue changes quick and easy.
3. The innovative injection tube constant temperature system and ultra-short nozzle minimize excess material and pressure loss.
4. Specifications below 500 tons utilize the internationally popular FIFO (First-in-First-out) injection method.
5. Zoned heating control on the hot plate ensures more uniform temperature.
6. The machine boasts a compact structure and a rational layout, offering fast injection speeds, uniform heating, precise material storage, reliable operation, and a low failure rate.
7. The mold base and injection position are both controlled by an electronic scale, ensuring precise positioning, high material storage, and injection accuracy, effectively reducing waste and defect rates.
8. Optional metering pumps with dual proportional valves, dual proportional variable pumps, and servo pumps are available. Combined with the electronic scale, these pumps enable three-stage control of mold base and injection pressure and flow, meeting various process conditions. 9. Pay attention to operational safety. The operation area is protected by a grating and can be started by both hands, with no safety hazards or blind spots.
