316 1.4016 Customized Stainless Steel Precision Casting Parts

Customized 316 Stainless Steel Material Investment Casting Precision Casting Parts

Ningbo Suijin specializes in the production of heat-resistant, wear-resistant, corrosion-resistant alloy steel, heat-resistant steel castings, stainless steel castings, heat-resistant steel and other precision investment castings, realizing centrifugal casting, lost wax precision casting, negative compaction casting, and machining Wait

In stainless steel precision casting, the use of high-frequency welding is to use the skin effect and proximity effect to form an electromagnetic induction loop at the opening, thereby generating a concentrated and powerful thermal effect, so that the edge of the weld is quickly heated to the temperature required for welding, and then After the metal becomes molten, it is squeezed to realize the bonding between the crystals. Finally, through cooling, a firm butt weld is formed.

There are many processes in stainless steel precision casting, and the main processes are:

Mold making → smelting → pouring → vibrating shell → cutting → rough grinding → pickling → hoisting polishing → fine spraying → solid solution → hoisting polishing → shaping → passivation → pickling → final inspection and storage
