The main products are various types of cotton gin, wool peeling machine, seed cotton washing machine, baling machine and other products. In 2005, we completed the product transformation, focusing on the production of cotton machinery parts, especially the production of cotton saw blades. Our factory has been devoted to the research of cotton saw blade technology for many years. The production scale and technical quality of cotton saw blade are in the leading position in the precision casting industry. In 2008, the seamless quenched empressed saw blade developed won the Hebei Provincial Science and Technology Progress Award, and saw blade sales steadily increased year by year. In 2005 to develop foreign markets, seamless quenched embossed saw blade by foreign users praise. In 2010, the company achieved sales revenue of 22 million yuan, profits and taxes of 2 million yuan, indirect export business of more than 10 million yuan foundry manufacturers. (1) Uneven thickness and unstable hardness occasionally occur in the cold rolling process of strip steel, which requires technical guidance.

(2) the hardness is not stable when quenching, and the toughness can not meet the process requirements, so technical guidance is needed. As production workers age and retire, companies are in urgent need of metallurgical and foundry personnel or expert guidance.
