METAL MOLD CASTING | BUSINESS

Gravity casting

This method injects molten metal directly into a mold made from cast iron or heat-resistant steel alloy.

The cooling speed when casting is quicker than sand mold casting. Other features include a beautiful casting surface and the ability to support more precise dimensions.
In terms of costs, metal mold production costs are higher than those for sand molds, but the cost of the product is low because a sand mold does not have to be produced every time.

This method is suitable for mass production, but we also cast metal molds for small-lot orders.

Durville casting

This method uses equipment that can be tilted at a certain angle. While controlling the inclinable speed of molten aluminum saved in a pouring basin, it pours the molten metal gently into the mold. The pouring flow is less turbulent than standard gravity casting, and it reduces contamination by impurities due to oxidization.

Durville casting is for orders of at least 30 pieces a lot and it is used for objects that are not thin-walled. Items needed for the core can be produced by the following methods.
(1) In-house cold-box casting (2) In-house furan casting (3) Outsourced shell casting

Low-pressure casting

Low-pressure casting uses a metal mold.
The casting surface is more beautiful than that of a sand mold, and it can achieve more precise casting dimensions.
It is suitable for orders of at least 30 pieces in the lot.
Items needed for the core can be produced by the following methods.
(1) In-house cold-box casting
(2) Outsourced shell casting
