Material: 304 Stainless Steel with Nickel Plating
Stainless steel is the most commonly used, cost-effective material for making battery contacts. The nickel-plating not only enhances the electrical conductivity but also provides some resistance to corrosion.
In addition to stainless steel, we can also use the following materials for manufacturing battery contacts:
-
Phosphor Bronze: Known for its excellent wear resistance and elasticity, making it ideal for components that undergo frequent friction, like battery contacts.
-
Beryllium Copper: Offers superior elasticity and fatigue resistance, maintaining its form after up to 100,000 compressions.
While copper-based materials offer better mechanical and electrical properties, they come at a higher price, making them more suitable for applications requiring higher performance.
Depending on the requirements for conductivity and corrosion resistance, we can also apply other surface coatings such as tin, silver, or gold plating.
Progressive Stamping for Efficient Production
Our progressive stamping process consists of 8 stations, each performing a specific action such as punching (in multiple steps), deep-drawing, bending, and blanking. After production, the finished parts automatically fall into collection bins.
With a stamping speed of up to 150 cycles per minute, we can produce two battery contacts per cycle, resulting in a production rate of 300 units per minute. This ensures high efficiency in manufacturing.

Manual Spring Assembly
The spring in this battery spring contact is manually assembled. Each time, the spring and the plate are placed together on the stamping machine by an operator. However, for large-scale production, it is possible to automate the spring installation process.
If the spring does not require plating, the stamping and spring assembly can be done in a single operation. For contacts that require plating, a different approach is needed, where the stamping and spring assembly are carried out as separate processes.
