1. Why choose investment casting?

1). Investment castings have high dimensional accuracy, general linear tolerance is 1%,
The angle tolerance is ± 0.5° , good surface finish, up to Ra 1.6-3.2, to save materials
& reduce machining cost.
2). Investment casting can produce parts or components with complex shapes, or cast
Several parts into one whole, to avoid combination or welding.
3). Beautiful text or LOGO images can be cast on the products to improve the image
Of your products.
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.
