Manganese Steel Investment 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, Wax pattern, Shell preparation, Metal pouring, Cleaning and Heat treatment, Inspection, Warehouse packaging, and Shipping.

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.

Manganese 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.

Questions About Stainless Steel Casting Service

What Is The Advantage Of Manganese Steel?

High hardness, wear resistance, good impact toughness.

What Are The Characteristics Of Manganese Steel?

Manganese steel is a kind of high strength wear – resistant steel, mainly used in the need to withstand shocks, extrusion, material wear and bad working conditions, is the most important characteristics of high manganese steel under the condition of strong shocks, extrusion, surface rapidly work hardening phenomenon, make its heart remained austenite good toughness and plasticity of hardening layer with good wear resistance at the same time.
