Custom Bus Bar Manufacturer
Sengrin is a subsidiary of Wcon. In 2023, Wcon (Weifeng Electronics Co., Ltd.) invested in Sengrin. Since then, our main business has become supplying components for international electric vehicles, and we also provide OEM services for busbars and other component products for small and medium-sized enterprises. We are committed to becoming a top-tier manufacturer and solution provider of high-end precision connector products.
Our company's structure focuses on production and research and development. We have 46 people in mold design, 107 in mold manufacturing, and 125 in metalworking and injection molding processes, providing full-process solutions from planning and design to manufacturing.
Mold Manufacturing: This is the step that tests our ability to implement plans. We have numerous machines, including Mitsui automatic surface grinders, Mitsubishi mirror EDM machines, CNC machining centers, and Charmilles precision wire-cutting machines.
Plastic Injection Molding: We have plastic injection molding machines with tonnages ranging from 7 tons to 30–450 tons. The brands of our machines include 19 Fanuc units, 38 Nissei units, 7 Sumitomo units, and 3 Nikkon units. We have 1,350 sets of plastic molds, all equipped with a fully automatic central feeding system.
