New Casting Method for Castings: Lost Foam Casting

New Casting Method for Castings: Lost Foam Casting

Casting technology for vanishing molds has been rapidly developed in recent years. With the disappearance of the completion and production of the die casting production line, significant economic and social benefits have been generated in the entire foundry industry. This has made the disappearing die casting technology still show its most powerful vitality.

1
Gas chamber: The gas chamber is an integral part of the mold. Its role is through hot steam, water and air. The gas chamber is sealed. Its size and height have an impact on the quality of the model and the production cycle. Careful consideration must be given when designing the air chamber for each part.

2
The connection of the material gun: The mold design should also be filled with beads from the storage tank into the material gun.

3
Back plate: The back plate is located on the back of the mold and acts as a cover plate to seal the air chamber.

4
, Public equipment connection: The model must communicate with steam, water and compressed air circulation. The water and steam pipes are installed on the back of the cavity to ensure the uniform circulation of steam and the rapid discharge of water during cooling. The air channel should be designed The top or side of the cavity.

5
Mold cavity: The mold cavity foams the beads. The manufacturing method of the mold determines the accuracy of the cavity. The surface of the mold cavity must be polished and have no back-slope.

6
Fixation of the mold: The mold (upper and lower) is fastened to the plate of the molding machine. The choice of the fixed part and type of mold varies with the characteristics of the molding machine and molding operation.

Disappearing molds are mainly used for the casting of vanishing molds. They mold the foam molds into compacted dry sands, so that the molten metal is poured under high vacuum and the metal liquids will be plastic. Mold gasification, combustion, and instead of forming a metal casting process.

Disappearing the mold can increase the dimensional accuracy of the casting and reduce the error rate of the casting.

2
Application of the surface of the casting mold disappears evaporative pattern casting and casting dry sand without binder evaporative pattern casting according to the casting molding material into its self-hardening sand.

,
Disappeared die casting without core, so that there is no parting surface, and flexible

The advantages of vanishing molds compared to traditional vanishing mold casting techniques are the unparalleled advantages of the vanishing mold casting techniques, which can save the foundry workers a great deal of time and effort.

Design process. this is okay

Produce castings in various shapes, thin-walled, porous channels.

,
Disappearing mold castings are very small, and the overall weight is very light, which can save a lot of processing time.
