China Customized Investment Casting Iron Rods with Surface Treatment

Surface Finish, Part Weight & Size Parameters

For industrial applications, the size limit of investment castings is usually between 3 g (≈0.1oz.) and 5 kg (≈11lbs.). The cross-sectional limit is usually between 0.6 mm (≈0.024") and 75 mm (3.0"). ). The typical tolerances are: 0.1 mm for the first 25 mm (0.005 inches for the first inch), and 0.02 mm for each additional centimeter (0.002 inches for each additional inch). The standard surface finish is 1.3 to 4 microns (≈50-125µin) RMS. Of course, all measurements depend on the design and complexity of the part.

Yifei Casting needs design drawings of parts to determine whether the weight and size can be produced by precision casting. If precision casting is not the best way to manufacture your parts, then we can also use other metal casting services to produce high-quality, high-precision parts.

Investment Castings for All Applications

Investment castings are used in the power generation industry to produce turbine blades with complex shapes or cooling systems. Blades produced by investment casting can include single crystal (SX), directional solidification (DS) or conventional equiaxed blades.

No matter what parts are used, any sophisticated investment casting foundry can produce close to the final shape in small castings with very high dimensional accuracy, although the tolerances will increase as the size of the casting increases.

Due to higher mold costs and higher than average total costs, precision castings are usually produced in larger production volumes.

We can provide you with investment casting parts, railway casting parts, railway parts, excavator machinery parts, mining machinery parts, construction machinery, agricultural machinery parts, sand casting, bucket teeth, auto parts, stamping and forging and valve parts. We have the ability to manufacture non-standard metal processing.
