Our precision investment casting process at QINGDAO SAYHEY INDUSTRY CO., LTD. utilizes advanced technology to produce high quality, detailed parts with a smooth surface finish. With over 20 years of experience in the industry, we have perfected our techniques to ensure precise and accurate results for our customers, Our investment casting process starts with creating a wax model of the desired part, which is then coated with a ceramic shell to create a mold. Once the mold is formed, it is heated to remove the wax and create a cavity for the molten metal to be poured. This process allows for intricate and complex designs to be accurately reproduced
