Nantong Juntai Alloy Fiber Co., Ltd. is located in Rugao City, Jiangsu Province, which is known as the hometown of longevity in China.  It is a professional enterprise specializing in the production of resistance microfilaments and electrothermal microfilaments. The company has a team of R&D and management talents, a perfect quality assurance system, advanced testing equipment and technology, and has passed ISO9001 quality system certification, 14001 environmental system certification, and EU-approved RoHS, ELV, REACH and other tests.  In October 2021, Nantong Juntai Electronic Materials Technology Co., Ltd. was established to specialize in the research and development of high-tech materials in the fields of aerospace and electronic components.
The modern production line that integrates drawing and annealing independently developed by the company has done well in the processing of wire arrangement, disk loosening, wire clamping, and resistance balance. During the heat treatment process, by improving the special process, the welding performance of the product for users has been improved.  At the same time, the equipment has computer numerical control frequency conversion control, constant tension winding, and the internal and external quality of each axis of alloy wire produced is consistent.  It provides high-quality quality assurance for users in the instrument and meter industry as well as the resistance and electrothermal industries, and also wins a good reputation for our company.

 

The buyer is visiting the factory to see the debugging and production of the machine. The buyer is visiting the factory on site:
We will conduct on-site inspections of the production workshops and production processes of the factory, focusing on whether the production equipment of the factory meets the standard requirements and whether the employee operations are standardized.
Products will be randomly selected for inspection to determine whether the quality of the products meets contractual and standard requirements.
I will understand the training situation of factory employees, including production operation specifications, quality control awareness, etc.
