What is precision casting?

Precision casting refers to the general term for the process of obtaining precise size castings. Compared with the traditional sand casting process, the castings obtained by precision casting are more accurate in size and have a better surface finish. It includes investment casting, ceramic casting, metal casting, pressure casting, and lost foam casting. One of the more commonly used is investment casting, also known as lost wax casting. Its products are precise, complex, and close to the final shape of the parts, and can be used directly without or with little machining. Shenzhen Yujiaxin Tech Co., Ltd uses lost wax investment casting to produce products.Produce all kinds of precision metal parts, such as pump body parts, connecting claws,Stainless steel side lugs, stainless steel pot handles, spiral nozzles, motorcycle parts, auto parts, equipment hardware, jewelry hardware, lock hardware.etc.

Precision Casting About Lost Wax Casting 2.0
Lost wax casting is now called investment casting. It is a precision casting process with little or no cutting. It is not only suitable for precision casting of various types and alloys but also produces castings with higher dimensional accuracy and surface quality than other precision casting methods. We use two kinds of wax materials to produce steel castings, namely yellow low-temperature wax and green medium-temperature wax, to meet the needs of different customers.

Create Wax Patterns
From the time we collect the customer's drawings, to the two parties reaching a consensus on the production conditions.The engineer completes the design and production of the mold according to the drawings. Use an automatic wax injection machine to make wax patterns. After the worker trims the wax patterns, it is handed over to the inspector for inspection. After passing the test, it will be transferred to the tree assembly process.

Tree Assembly
Wax patterns are connected to a central wax stick called a runner which includes the sprue to form the tree assembly. It should be noted that different products have different tree forming processes to maximize benefits. The role of the central wax stick is to create a flow path for the alloy solution to flow into the various hollow crevices of the wax mold.
