All stamping terminals and pins Hai Tong manufacture are customized and all rights will be reserved and non-disclosed to third party without written agreement from customer, this phosphorous bronze terminal is needed 6 million per year. Designed for application in automotive, we stamped this terminal from phosphorous bronze coil that was 0.5mm thick and apply tin plating as a finish and bulk packed for delivery. Our tolerances were maintained at ±0.02mm throughout the processes and we worked with the inventory to keep a schedule for just-in-time delivery, our production is 120000pcs daily with progressive die stamping, very cheap production cost to keep us competitive in the market and long term business relationship with customers.

Hai Tong focus on sheet metal parts and we are professional sheet metal bender in China, we develop various kinds of sheet metal boxes using blanking, bending, TIG welding, grinding, and powder coating, some sheet metal boxes can be waterproof with IP65.

Metal stamping pin, contact, terminal are widely used on electronics like socket, switch, plug, battery, PCB, car antenna, car charger, material usually is copper, beryllium; copper, phosphor bronze with super electrical conductivity, and they can be silver, gold, tin, nickel plated with 4-10 micron thickness.

Metal spring, Metal bracket, metal enclosure with high tight tolerance and big volume demand in battery and electronics industries,we design high precision progressive die and production on high speed press machine with at least 150000pcs daily, low production cost and high precision are the characteristic of our small stampings,you can choose stainless steel, 65Mn, and the stampings will be heat treated with salt bath, which minimize the deformation, after heat treatment, the stamping parts will have super good spring.
