Quality Control

With the company's R & D center as the core, we adopt a combination of independent research and development and open research and development, and work closely with many domestic universities and research institutes. The use of the latest research results and the latest domestic advanced technical means to produce the most cutting-edge products in the casting industry. Science and technology leads to fashion, science and technology creates wealth.

Quality Control

Raw Material: choose high quality edge materials from steel mills and high quality cold pressed plates from automobile manufacturers to press the briquettes.
Modeling: adopt iron mould covering sand process to improve the appearance quality and inner toughness of the product.
Formula of Furnace Charge: through computer sampling test to reach product qualified ratio, production can continue.
Melting and Pouring: Adopt advanced American Inda intermediate frequency furnace, chemical composition for quality inspection before furnace, to achieve melting ratio needs. The pouring machine is controlled by computer imported from USA, and the bottom method of pouring is implemented to improve the quality of iron, which must be finished within the effective time. If not, it will be returned to the furnace for new melting ratio until qualified.
Sand Clearing: Set a certain time to separate the semi-finished products from the sand clearing process.
Heat Treatment: Adopt self-developed heat treatment process, with fully automated computer programming control, using isothermal heat treatment, the secondary stress relief.
Substandard Products and Waste Products: In the whole stress treatment process, any substandard products and waste products will be returned to the raw material.
Finished Products: We use six quality control processes to eliminate the secondary stress and finally reach qualified products.
