Liquid Rubber Injection Machine

Liquid rubber injection machine is the equipment that inject two kinds of liquid rubber at different ratio into the mold through dosing units and then mold by vulcanization. The rubber injection machine is composed of dosing unit, injection unit and clamping unit, among which, the clamping unit can be divided into horizontal type and vertical type to meet different requirements. The machine is broadly applied for producing electric appliance, medical facility, baby products, electronic components, auto parts and sports goods, etc.


Horizontal liquid silicone rubber injection machine:

1. Horizontal liquid silicone rubber injection machine is equipped with German Reinhardt-Technik dosing and feeding system, which ensures its stable performance.
2. The dosing and feeding process are controlled by gas pressure and valves with the precision rate up to 0.2-0.3%.
3. The dosing unit can automatically cut-off while the raw material is used up for less material wastage and long service life.
4. The injection unit of the horizontal liquid silicone rubber injection machine adopts direct hydraulic clamping mechanism and closed-loop control of clamping force, which realize high precision control of clamping position.
5. Single injection cylinder guarantees precision control of injection volume and pressure.

Vertical liquid silicone RIM:

1. The vertical liquid silicone RIM adopts servo-driven motor plunger and high pressure oil pump as the machine’s power source to realize energy-saving, water-saving and cost-saving;
2. By adopting S98 Smart B&R control system and the world famous brand electrical components, the machine can effectively reduce little fault of the electrical parts; 10.4-inch color display and user-friendly man-machine interface are also mounted on the machine.
3. We can access instant working conditions and production data of vertical liquid silicone RIM whenever and wherever via iSee Mobile Apps;
4. The metering device can be continuously measured and it is able to meet the requirements of different products on rubber injection volume;
5. Imported high-quality static mixer ensures an even mixture of material A and B;
6. The machine adopts gas as the power source to maintain clean and hygienic working condition; 7. The standard ammeter provides intuitive feeling and energy-saving benefits.
8. The Ethernet interface realizes remote VNC control functions and long distance maintenance procedures.
9. The whole series of DKM rubber injection machine are accredited by CE certificate, which is safe and reliable.


Liquid silicon rubber injection machines are developed special for producing the liquid silicon rubber articles; they adopt high precision dosing unit and mature clamping unit to realize the advantages of high precision, high efficiency, energy saving and stability to produce all kinds of liquid silicon rubber articles.
