Dongguan Foundry

1 Overview

Dongguan Precision Casting is also called&"dewaxed casting GG". Generally, several layers of refractory are applied to the wax mold profile. After it has hardened and dried, the wax mold is melted away to form a shell, which is then baked However, the casting is left behind, and a kind of system for obtaining castings. Because the obtained castings have higher dimensional accuracy and roughness, it is also called"investment precision casting"

Dongguan FoundryProcess. The types of alloys that can be produced by precision casting include carbon steel, alloy steel, heat-resistant alloys, stainless steel, precision alloys, permanent magnet alloys, bearing alloys, copper alloys, aluminum alloys, titanium alloys, and ductile iron.

The shapes of wax mold castings for dewaxing casting are individually complicated. The minimum diameter of the holes that can be cast on the castings can reach 0.5mm, and the minimum wall thickness of the castings is 0.3mm. In production, some parts can be assembled from several parts from the original source. The structure of the parts is transformed through the process, and the parts are designed to be integral parts and directly cast by precision casting. The processing time and the waste of metal materials are saved to make the parts The structure is double fair.

The weight of investment castings is mostly a few dozens of cattle (that is, tens of grams to several kilograms). It is more troublesome to produce heavy castings by precision casting, but the weight of large investment castings has reached 800 cattle.

The precision casting process is more complicated, and it is not easy to control, and the materials for operation and consumption are more expensive. Therefore, it is suitable for the production of small parts with complex shapes, high precision requirements, or difficult to perform other processing, such as the blades of turbomachines, etc. .
