Investment Casting Lost Wax Casting

 Lost wax investment casting can reach dimensional tolerance grade CT 5-7 according to ISO 8062. Our fully organized equipment and automation process controls allow for consistent and repeatable tolerances as close as ±0.1 mm. The lost wax casting parts can also be produced in a wide size range, they may be as small as 10 mm long x 10 mm wide x 10 mm high and weigh as little as 0.01 kg, or as big as 1000 mm in length and weigh as much as 100 kg.

 Investment casting, which is also known lost wax casting or precision casting, refers to the formation of ceramic around the wax patterns to create a multi or single part mold to receive molten metal. This process utilizes an expendable injection molded wax pattern process to achieve complex forms with exceptional surface qualities. To create a mold, a wax pattern, or cluster of patterns, is dipped into ceramic material several times to build a thick shell. Die-wax process is then followed by the shell dry process. The wax-less ceramic shell is then produced. Molten metal is then poured into the ceramic shell cavities or cluster, and once solid and cooled, the ceramic shell is broken off to reveal the final cast metal object. Investment castings can achieve exceptional accuracy for both small and large castings in a wide range of materials.

Conventional enzyme production is mainly produced by hand, hand-sliced, hand-fermentation, the company every step of the process are used self-developed technology and equipment to automate production. Moreover, the conventional enzyme production have adopted a fermentation technology, enzyme often taste discomfort, sour and other issues, I produced using a variety of enzymes, probiotics composite grade fermentation technology, fermentation at different times with different strains, and two or three times through fermentation, enzymes such pure taste, streptozotocin balanced nutrients.
