In 2017, the in-house laboratory of Guangdong Zhongxiang New Materials Co., Ltd was established to monitor the whole production process, ensure the stability of raw materials, mixed-rubber compounds chemical analysis, and the reliability of the production process. The consistency of product quality, and the uniqueness of quality control. so as to achieve high-quality products. And the experimental equipment has been improved year by year, which can meet the needs of testing various performance of products. We test all materials and products to meet industrial, national standards, and customer-specific requirements.
