Precision casting is now the key is for steel and metal materials class production and processing more, many of the metal materials must be precision casting and then complete the other actual operation, in precision casting must ensure that the quality of the upgrade, then will find that the production and processing will be much easier later. The basic practice of high precision casting or more simple. Precision vacuum casting alone from the process seems to be able to carry out a multi-faceted grasp of its process. To ensure the quality of castings goods, you need to master each manufacturing process.
1. mould shell overall planning: stainless steel plate castings of the appearance of the solution first from the mould shell, the appearance of the machine tool to solve the clean, that is, the appearance of the sandpaper wiped clean with sanding brush fluorine benzene paint material, high-precision castings using metal materials or injection mold, the development of the smoothness of the appearance of the mould shell. Sanding overall planning: sanding stage to get rid of the hairy edge burrs, the appearance of the uneven place, carry out sanding solution, wetting too much. About heat treatment process finished castings using grinding fine polishing solution. 2. process overall planning: strict control process, before closing the box, to ensure that the appearance and sand core is with temperature situation, pouring to ensure the flow of steel, the appearance is not smooth damage to the area using Fosco ISOMOL300 alcohol oil zirconium powder architectural coating to carry out brushing after hitting the fire baking, so that the cast appearance wetting.
3. wall thickness overall planning: precision casting manufacturer details due to the metal material type exhaust heat fast, so the stainless steel plate forging small wall thickness should be larger than the sand mold forging castings, a variety of forging aluminum alloy. Not the same size forging small wall thickness.
