Why choose investment casting?

1). Investment castings have high dimensional accuracy, general linear tolerance is 1%, angle tolerance is ± 0.5°.

2). Beautiful appearance, surface finish up to Ra 1.6-3.2, save material and machining cost.

3). Text or LOGO can be cast on the products to show company’s brand.

4). The performance of materials for investment casting are very extensive, wear-resistant, heat-resistant and corrosion- resistant, the hardness of the material up to HRC15-60, to meet the demands of different industries.

5). Investment casting approved flexible production volume, from a small number to high-volume production, high efficiency and good reproducibility;Low-cost mold, less input in the early product development.
