Make molds according to different shapes of products. Precision casting includes many process types. Gold casting. Ceramic casting. Silica sol casting and investment casting. Although stainless steel precision casting is precision casting, but each casting process has its own characteristics and industry status. It can be said that any precision casting process is independent.

Aluminum alloy molds are used to produce large quantities of industrial wax solid models. Normally, an industrial wax solid model can only correspond to a rough product.

The essence of stainless steel precision casting is to apply great mechanical pressure to the liquid metal in the quantitative casting cavity to make it formed. The invention relates to a process method for obtaining blank parts by crystallization solidification. This process is also called "liquid metal die forging". "liquid metal stamping". Liquid metal forging. International die casting Association unified name "punch pressure crystallization" Squeezecasting according to translation, domestic collectively known as squeeze casting.

Precision casting

Compared with other casting methods and parts forming methods, precision casting, also known as investment casting, has the following characteristics:

The dimensional accuracy of castings is high, the surface roughness is fine, the dimensional accuracy of castings can be up to 4-6, the surface roughness can be up to 0.4 -- 3.2μm, which can greatly reduce the machining allowance of castings, realize no surplus manufacturing, and reduce the production cost.

The shape of the casting is complex and difficult to be processed by other methods. The contour size of the casting is as small as a few millimeters to a few thousand millimeters. The wall thickness is 0.5mm and the Z hole is less than 1.0mm.

Alloy material is not limited: such as carbon steel: stainless steel. Alloy steel. Copper alloy. Aluminum alloy and superalloy. Titanium alloy, precious metals and other materials can be produced by casting. Weld-cut alloy materials are especially suitable for investment casting.

Precision casting is a kind of casting with little or no cutting, and the surface is beautiful. The overall precision is high and the quality is good. Many buyers also buy precision castings for these features. Among them, the demand for stainless steel precision castings is the most vigorous.

Precision casting parts

Compared with the precision castings of other materials, the service life of stainless steel precision castings is longer, and many people think that this is related to the stainless steel material will not rust. Is this popular guess really correct?

In fact, stainless steel material is not really rust, if the production process is not handled properly, the surface of stainless steel precision castings will still rust. So, in order to prevent the rust of precision castings, what do precision foundries usually do? Usually, in order to reduce the rust factor of precision castings, precision casting manufacturers will carefully consider from multiple angles to minimize the chance of rust.

Precision casting parts

1. In terms of structural design, precision casting manufacturers will carry out, which is conducive to the model. Core box production and modeling design. When selecting the mold core, the precision foundry will ensure the permeability of the mold and steadily discharge the large amount of gas generated during the pouring of stainless steel metal liquid; The structure of precision castings should be closed as far as possible during cooling and solidification

2. In external casting, the appearance of precision castings should be simple and easy to cast, to fully ensure the flatness of each plane of the castings, to prevent dust or part of the chemical composition hidden in the holes, resulting in chemical corrosion of the castings.
