In the fierce competition of modern society, product quality is an important factor to ensure the survival and development of an enterprise. Since its establishment, Zhongzhi has strictly controlled the product quality and formulated a strict quality testing system in all links of production to ensure that our products meet or exceed the requirements of customers and achieve zero defects in the delivery of products.

We have passed the ISO 9001:2000 quality management system certification and ISO 14001:2004 environmental system certification, and carry out product testing in strict accordance with the relevant provisions of the quality management system. The quality inspection department of the company is equipped with 20 quality inspectors, including inspectors, sequence inspectors and final inspectors to check the products at all levels. 38 product testing procedures have been established, which can carry out professional and all-round testing of products, increase investment in testing equipment, introduce foreign advanced equipment, and establish a strong testing team to provide strong support for each testing. At the same time, producers use special measuring tools for self inspection, and a strong quality inspection system has become a strong guarantee for the high-quality products and market competitiveness of Zhongzhi.
