Precise Dimensional Tolerance

Smooth Surface Roughness

Cost Reduction

Investment casting, also known as "precision casting", "lost-wax casting" and "casting", can melt a wide range of materials and is not restricted by the complexity of product shape and structure. Its most important features include precise dimensional control, minimal machining allowance, and flat and smooth surface. With the gradual launch of new equipment and advanced technologies, its applicable scope is becoming wider and wider. In the field of hot working, investment casting can be applied to parts that are difficult to obtain materials, difficult to form, and some forged parts with high processing costs; in the field of casting, some products can use investment casting instead of other forms of casting, reducing machining allowance to lower costs, improving dimensional accuracy, surface roughness and mechanical properties of materials, thereby achieving the purpose of upgrading product quality.

We undertake processing cooperation with drawings and samples at home and even around the world. If you have products that need quotation, please submit relevant inquiry materials, and we will send you the best price as soon as possible. 
Mature technological processes, rich historical experience, professional large-scale production, and effective cost management have forged our strong comprehensive competitiveness that stands out from peers. It is not only reflected in our high product quality, but also the highly competitive price is the winning weapon for us to gain a broad market at home and abroad.
