Manganese Steel Investment Casting Process
The technical department develops the mold, and the quality department uses the three coordinates to carry out the dimensional inspection.
The workshop uses automatic waxing machines to set the waxing pressure, holding time, etc. and to produce high quality was patterns.
The workshop has 4 automatic production lines, able to produce 1800 sets of shells. DaWang manganese steel casting foundry uses hygrothermograph, aerometer, and PH to monitor humidity, temperature, and concentration of liquor aluminum chloride.
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.
The manganese steel casting process is fully equipped with 8 heat treatment furnaces, 3 quenching furnaces, 1 central shot blasting machine and 11 large shot blasting machines.
All blank dimensions are checked using a CMM. DaWang manganese steel casting foundry have rockwell hardness machine, dynamic balance instrument, roundness meter, etc. The company’s quality department has certified employees to do UT, PT, MT testing.
The TechnologyManganese Steel Sand Casting Process
DaWang manganese steel casting foundry each manganese steel casting process is executed in strict accordance with the Standard Operation Procedure (SOP). The main manganese steel casting 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.
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. DaWang manganese steel casting foundry’s mold is mainly made of aluminum.
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.
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)
Pour qualified molten metal into the sand box equipped with the mold. The pouring stage has high safety requirement, and DaWang manganese steel casting foundry has rigorous process control to protect the safety of our employees.
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.
All blank dimensions are checked using a CMM. DaWang manganese steel casting foundry has rockwell hardness machine, dynamic balance instrument, roundness meter, etc. The company’s quality department has certified employees to do UT, PT, MT testing.
