Rubber injection moulding machines
Based on customer needs we offer high-quality process solutions. Yizumi has developed 6 conventional machine models and customized machine models according to the customer’s moulding process.
Yizumi rubber machines, which continue to innovate technologically, improve the customer experience and continuously improve customer competitiveness, won the national burner program in 2012, which focuses on high-tech companies.
Similar to thermoplastic injection moulding, rubber injection moulding involves the transfer of free-flowing granules into a processable (viscous) state. The unit is tempered to low temperatures between 60 – 100 °C for this purpose. Crosslinking is then carried out on the heavily heated injection mould.
Two rubber injection moulding machines are available in the Yizumi Germany program. These differ in the construction of the machine beds and the access to the tool. One is the C-Line, which is characterized by a power transmission via a C-frame. This allows easy access to the tool and the finished product.
In addition to the C-Line, Yizumi offers the H-Line as the most compact small injection moulding machine in a horizontal series.
High-strength, reliable and durable
The clamping unit strongly determines the machine type in the Yizumi product portfolio. A distinction can be made between two-platen clamping units and toggle-joint clamping units (electric / hydraulic). All Yizumi clamping units are high-strength, reliable and durable.
In the A5 series, the uniform stress forming technology and the highly rigid T-slot plate design protect the plates and moulds and increase the service life of the overall system. Special anti-tilt plate support design and low pressure mould protection can effectively protect the mould. Forced ejector reset allows for better mold usability.
Precise and stable with superior plasticizing effect
The optimized design of the injection unit increases stiffness, ensures coaxiality of forces on movement and injection and reduces resistance. The highly efficient mixing screw is standard on the entire machine series, which significantly increases plasticizing efficiency and quality and achieves an excellent color mixing effect.
Energy saving, high efficiency and low noise level
With regard to the optimization of the servo system, it redefines the higher-level configuration. Combined with a renowned special motor, an imported high-pressure gear pump and an Inovance servo amplifier, the third-generation servo system can react quietly, powerfully and quickly.

Questions & Answers
What is the difference between rubber injection moulding and thermoplastic injection moulding?
The basic process of forming (injection moulding) is identical. However, since elastomer molding compounds crosslink to form an elastomer from a material-dependent activation temperature onwards, the two processes differ essentially in their temperature control. In elastomer injection moulding, the material is initially only brought to a moderate processing temperature. In the hot mould, the cross-linking then takes place. In thermoplastic injection molding, the molding compound is first heated to a high temperature and cooled in the mold.
Rubber injection moulding and thermoplastic injection moulding can be reproduced on one machine.
In principle this is possible. However, the problem of different temperature control must be solved with smart tool technology.
