Vertical Rubber Injection Machine For Sale

Vertical Rubber Injection Machine is a kind of equipment specially used for the production of rubber products, which is a kind of rubber injection machine. Compared with the horizontal rubber injection machine, the structural difference of the vertical injection machine is that the injection unit and the mould clamping unit are arranged vertically, and during the injection process, the injection unit opens upwards and the mould opens vertically. This equipment is more suitable for the production of some rubber products which need to fill complex moulds or have special shapes.

Working Principle

The working principle of the vertical rubber injection machine is similar to that of the horizontal rubber injection machine, which involves the steps of heating, injecting, cooling, and taking out of rubber, etc. The control of the injection process is realized through the setting of parameters such as temperature, pressure, and injection speed as follows:

Heating: Solid rubber granules or lumps will be put into the hopper of the injection machine, which will be heated and processed to transform it into a molten state that can be injected.

Injection: The rubber material, which has reached the molten state, is injected into the mold under the high-pressure push of the screw, filling every void in the mold evenly.

Cooling and curing: after the injection is completed, the mold remains closed under the action of the tightening unit, and the rubber is cooled and cured in the mold.

Mould opening: after the rubber has cured, the mold is opened by the mold clamping unit, and the final rubber product is taken out.

Key Advantages and Features

Vertical rubber injection machines have some specific advantages and features over horizontal injection machines, making them more suitable for specific rubber product production.

Small footprint: Because of its vertical structure, it occupies less floor space, making it suitable for production environments with limited space.

High production efficiency: as the injection process is vertical, under the effect of the gravity factor, it helps the rubber material to fill the mold more smoothly and improve the injection efficiency.

Convenient installation and replacement of molds: the moulds are installed from above the equipment, and the molds are opened vertically during the injection process, which makes it easier to install and replace the molds.

High injection precision: the injection direction is vertical which helps to precisely control the flow of rubber material and improve the precision and consistency of material molding.

Adaptation and special process requirements: Due to its vertical injection direction and structure, it is more adaptable to some special process requirements.
