Steel casting process

Steel castings themselves can participate in the general assembly without processing, such as track chains, etc. But most castings can form parts after being processed. So castings are basically rough machining parts, especially in some parts of high precision size requirements. They can take part in the assembly, and equipment is also the basic approaches after processing. So what is the cast steel mould casting process?

The process:

1. Make white foam mold, combination of gating system, gasification mold surface brush, spray paint and a special high-temperature drying.

2. Put special compartment flask on a vibrating bench, fill in the bottom sand (dry sand) tap, evenness, and then place the drying gasification mold on the bottom sand, fill the dry sand, calibrating the box mouth during the micro-vibration time.

3. Cover with plastic film, place pouring cup, then contace the vacuum system to suck vacuum, dry sand molding fastening for casting, white mold vaporized away the molten metal replaces its position.

4. Release the vacuum, turn boxes after cast condensation, then remove the casting from the loose dry sand.
