CRI 3000KN Rubber Injection Molding Machine
- Model: CRI-3000
- Heating Plate Size: 650 mm×700 mm
- Clamping Force: 3000 KN
Compact and efficient, CHAP rubber injection molding machine is particularly suitable for producing rubber products that are difficult to mold, like those with complex shapes.
- The PLC control system ensures operation is stable and reliable, with a low failure rate. Omaron or Siemens PLC systems are available upon request.
- This rubber molding machine's heating plate is heated using an electric heating pipe. It uses a PID closed loop control to strictly monitor the heating plate temperature uniformity of the heating plate.
- The CRI3000 rubber injection molding machine features a four-cylinder parallel injection structure which improves the balance during the rubber injection process, and cuts down on the longitudinal space of the injection component. As a result, the injection plunger is easy to remove.
- This molding machine uses electro-hydraulic proportional variable pump technology and is equipped with a German proportional variable pump, which significantly reduces system energy consumption while increasing operation speed.

The rubber injection molding machine works by injecting plasticized and metered materials into a closed mold cavity and thus producing parts of desired shapes.
What are the advantages of injection molding compared to compression molding?For complex parts, high-volume production and multi-cavity molding, injection is more suitable in terms of better repeatability and less manual intervention.
The actual production efficiency, material utilization and product consistency depend on material formulation, mold design and other parameters.
A rubber injection molding machine from us can be used for rubber molding and vulcanization/curing.
What are the configurable parameters of a rubber injection molding machine?Injection volume, injection pressure, screw speed, temperature, and curing cycle, etc.
What are the applicable materials for a rubber injection molding machine?Both natural and synthetic rubbers can be processed using the rubber injection molding machine.
Different rubber compounds may vary in viscosity, flow behavior, curing temperature and suitable product design. Therefore, you should adjust injection pressure, screw speed and temperature based on actual processes.
Examples: natural rubber (NR), nitrile rubber (NBR), EPDM rubber, styrene-butadiene rubber (SBR), chloroprene rubber (CR) and fluoroelastomer (FKM).
Specialty materials can be suitable depending on the actual compound formulation, Mooney viscosity, curing system, product geometry, and mold design.
The rubber injection molding machine can be used for complex rubber parts, and rubber products requiring repeatability and consistency.
Examples: O-Rings, oil seals, rubber seals, rubber gaskets, rubber bushings, anti-vibration parts / vibration dampers, rubber boots / dust boots, rubber diaphragms, rubber-to-metal bonded parts, etc.
With 3,000 kN clamping force and 3,000 cm³ theoretical injection capacity, the product range extends to automotive rubber components, industrial seals, pump and valve rubber parts, electrical rubber components, other damping and sealing products.
The suitability for a specific product depends on part dimensions, rubber compound weight per part, mold dimensions, cavity count, required shot volume, and curing process.
