Seeking affordable stainless steel investment casting manufacturers? Do not hesitate to contact us.  

Mold Development

The technical department develops the mold, and the quality department uses the three coordinates to carry out the dimensional inspection.

Wax Pattern

The workshop uses automatic waxing machines to set the waxing pressure, holding time, etc. and to produce high quality was patterns.

Shell Preparation

The workshop has 4 automatic production lines, able to produce 1800 sets of shells. We use hygrothermograph, aerometer, and PH to monitor humidity, temperature, and concentration of liquor aluminum chloride.

Metal Pouring

4 sets of 500KG furnaces are in production, and 3 sets of 500KG spare furnaces are ready when capacity increases. The operators conduct rigorous tests to fulfill material requirements.

Clean and Heat Treat

The workshop is fully equipped with 8 heat treatment furnaces, 3 quenching furnaces, 1 central shot blasting machine and 11 large shot blasting machines.

Inspection

All blank dimensions are checked using a CMM. We have rockwell hardness machine, dynamic balance instrument, roundness meter, etc. The company's quality department has certified employees to do UT, PT, MT testing.

Stainless Steel sand casting Process

Each process of our production is executed in strict accordance with the Standard Operation Procedure (SOP). The main process is as the following: Pouring simulation, Mold development, Raw material inspection, Modeling (Core-Making), Melting, Metal pouring, Cleaning and Heat treatment, Inspection, Warehouse packaging, and Shipping.

Mold Development

Design and produce molds according to the requirements of the drawings. Generally, wood molds can be used for single-piece production, plastic molds and metal molds are made for mass production, and templates can be made for mass castings. Our mold is mainly made of aluminum.

Modeling (core-making)

Includes modeling (forming the cavity of the casting with molding sand), core-making (forming the inner shape of the casting), and mold matching (putting the core into the cavity and closing the upper and lower flasks). Modeling is a key process in casting.

Melting

According to the required metal composition, the chemical composition is matched, and the appropriate melting furnace is selected to melt the alloy material to form a qualified liquid metal liquid (including qualified composition and qualified temperature)

Metal Pouring

Pour qualified molten metal into the sand box equipped with the mold. The pouring stage has high safety requirement, and we have rigorous process control to protect the safety of our employees.

Clean and Heat Treat

After the molten metal is poured and solidified, the molding sand is removed, and the gate and other attachments are knocked out to form the required casting.

Inspection

All blank dimensions are checked using a CMM. We have rockwell hardness machine, dynamic balance instrument, roundness meter, etc. The company's quality department has certified employees to do UT, PT, MT testing.

As the leader stainless steel castings manufacturer in China, we are always trying to provide efficient and high-quality casting process.

As one of the best stainless steel castings manufacturers in China, we provide a reasonable price for our customers.

The basic raw casting price start from 5 USD/KG.

Yes. As the leader stainless steel castings manufacturer in China, we have discounts for our customers when they purchase an amount of casting parts.

About stainless steel casting parts: when the total weight (1 kind) reach 10 tons or quantity reach 10,000 pieces, return the mold fee.

The main difference is the carbon content. 304 is qualified if the carbon content is below 0.08%, while 304L is qualified below 0.03%. The more popular carbon content means the quality. The lower the carbon content, the better the corrosion resistance of the material. Most stainless steel castings manufacturers can provide different types according to the customers’ requirements.
