Valve-tek provides a one-stop casting solution, specializing in the manufacturing of high-quality investment casting products. Lost wax casting, also known as investment casting, is utilized to manufacture parts with tight tolerances, thinner walls, and surface finishes that require minimal post-processing. We insist on using premium casting wax imported from Japan to ensure the stability and quality of our products. Additionally, we use casting sands imported from the United States and Australia to ensure the high-temperature performance of our shell molds.

Casting Sand (Process of Dipping & Stuccoing)

We use casting sands imported from the United States and Australia, which have the characteristics of high temperature resistance. Depending on the size and shape of the casting design, we sequentially coat different particle sizes of casting sands, at least four layers, and up to six layers, to form a shell mold. Our shell mold production process is rigorous, ensuring that every casting obtains the best surface smoothness and accuracy.
