Vacuum Mold

The CUMSA vacuum system removes the air from the plastic mold before filling, creating a negative pressure that allows the injection to be completed in an instant.

It can shorten the molding cycle time, solve the weld line of the product porous position filling, and avoid the product air trap and burning issue, reduce injection pressure. When the material is filled at high speed in the mold cavity, it is often difficult to fill due to the complex product structure and the principle of fluid mechanics, which is air trap.

The air trap is usually located in the area at the end of filling, so the mold must be designed with sufficient venting channels or use the mold vacuum negative pressure adsorption technology to achieve.

In the past, Immetech Industrial and CUMSA vacuum negative pressure adsorption solution provider have provided a series of innovative solutions to customers around the world, bringing high quality molds and products to customers. The molding cycle time is shortened, the defect rate and production cost of the product are reduced.

For example, Dorel's 5-star car seat; Honda's complex auto parts; China Mobile high-end mobile accessories.
