company profile

Natural Technology International Limited. (Formerly know as: Natural Chemical Work Company) was established in Hong Kong in 1994. With one subsidiary setting up in Guangzhou in 2000 and the other in Suzhou in 2003, our production base was established in Jiangmen in 2006. Over the past 22 years, we have been committing to the R&D, manufacturing and selling of welding materials. The company mainly produces solder bar, solder wire, solder paste etc, and all the products have passed ISO9001 Quality System Certification and ISO014000 Environmental Management System Certification, and all lead-free products conform to ROHS standard. Besides, we are devoting ourselves into manufacturing and developing other welding materials with applications in various fields. Since 2003, we have been developing aluminum-copper and aluminum- aluminum flux cored solder materials, and the company has obtained 17 patents of invention. In the future, we will uphold the enterprise aim of “technology leading, continuous innovation”, and keep improving our products and services.

Technical Advantage

Technology research and development center is founded in 2009. In recent years, the company has obtained 8 patents for invention and 3 of them have realized the commercialization of research findings. The solder ring developed by Lichuang has meet requirement of copper clad aluminum composite tube soldering.
Strict Quality Control Process:
Notice of incoming quality control→incoming quality inspection material into warehouse process inspection→semi-finished/finished product acceptance→warehousing finished product → outgoing quality control
