VERTICAL INJECTION MOULDING MACHINES

Compared to horizontal presses, vertical injection moulding machines are less common. The two presses resemble each other in the way the injection unit is mounted horizontally. The tool opening, however, is in the vertical position. Vertical injection moulding machines are mainly used for products that are overmoulded. Overmolding is usually a process in which a softer, malleable material is injected over a rigid plastic. There are three options for overmolding: Insert molding, two-shot molding and co-injection. These methods differ in the technique of forming parts.

HORIZONTAL INJECTION MOULDING MACHINES

Horizontal injection moulding machines are the most common machines on the market. It bears its name because the mould and the injection unit open and close horizontally. To ensure that injection moulding machines of this type maintain heat stabilization, the sprue bushing remains in contact with the injection unit. Maintaining heat stabilization is the key to optimal injection. This ensures that the quantity of surplus material is kept to a minimum and the quality of the sprayed product is free of defects. Once injected, gravity helps eject the part as soon as the mold opens.
