Metal Casting • Plymouth Foundry

Sometimes called non-expendable mold casting, permanent mold casting uses permanent molds that are reused after each production cycle. Although permanent mold casting produces repeatable parts due to re-use of the same mold, it can only produce simple castings as the mold needs to be opened to remove the castings.

Classification of sand casting process – ZHY Casting

The mold for low pressure casting can be sand mold, shell mold, ceramic mold, metal mold, graphite mold, etc. On the basis of low-pressure casting, the method of filling and solidification of liquid metal under differential pressure is called differential pressure casting, which is a special form of low-pressure casting.

Investment Casting Supplier

Investment castings, which are often referred to as lost-wax castings, are metal parts that are produced by the investment casting process. This expendable mold process (along with the components it produces) is extremely popular for countless applications in numerous industries.

Graphite Permanent Mold Casting

The graphite permanent mold casting process begins with pneumatically clamping two graphite blocks in a press. Molten metal is poured into a sprue or pouring basin at the top of the mold. Once the metal has solidified, the graphite molds are separated and the castings are removed.

Permanent Mold Casting

Permanent mold casting, like die casting, uses a metal mold (die) that is typically made from steel or cast iron and can be reused for several thousand cycles. Because the molten metal is poured into the die and not forcibly injected, permanent mold casting is often referred to as gravity die casting.

Permanent Mold Zinc Castings

ISO 9000 QS 9000 certified mold casting services including zinc permanent mold casting. Castings range from 3 oz. to 1,760 oz. Castings can be designed with thinner walls lower weight, also the cast surfaces are smoother closer dimensional tolerances can be maintained.

Graphite Mold Casting,Graphite Mold Casting

Graphite mold casting is a cheaper alternative to other casting methods which helps mass production of quality casting like camera housings. Process: Graphite mold casting process is a simple process where a plastic aggregate consisting of graphite grains, pitch, carbonaceous cement, starch and water are use for making the mold.

Aluminum gravity casting,Permanent mold casting

Like other casting processes, aluminum gravity casting process starts from the developping of mold by CNC machines. Then, melt aluminum ingots into liquid status, and pour the aluminum liquid water into the permanent molds to fill the cavity by handwork or by gravity casting machines.

Investment Castings

Very similar to die casting, permanent mold casting sees molten metal gravity-poured into cast iron molds and coated with ceramic mold wash. Cores can be metal, sand, sand shell, or other material. Once the process is complete, the molds are opened and castings are ejected.

Investment casting

Investment casting is an industrial process based on lost-wax casting, one of the oldest known metal-forming techniques.[1] The term lost-wax casting can also refer to modern investment casting processes. Investment casting has been used in various forms for the last 5,000 years. In its earliest forms, beeswax was used to form patterns

Permanent mold casting

Permanent mold and sand casting have similar processes by pouring a liquid metal solution in the mold to produce the permanent cast. While sand casting has been used readily for centuries, permanent mold castings usually have better mechanical properties than sand castings because solidification is quicker, and the fill is more consistent and accurate.
