    The most attractive feature of newest spot welding equipment is that the energy delivered to the spot can be controlled to produce reliable welds.

  • Heat Shrink Oven

    Heat Shrink Oven
    The Heat Shrink Oven shrinks tubing in a fraction of the time required by a heat gun as it reaches the optimum operating temperature to quickly and uniformly shrink tubing.

  • Soldering Stations

    Soldering Stations
    Our dedicated and ESD protected soldering stations allow us to manage multiple assemblies during our 24/7 operation.

  • Wire Cutting and Stripping

    Each custom battery pack that requires a plastic enclosure can be sealed by adhesives, mechanical screws or the latest in ultrasonic technology.

  • Pull Test Equipment

    Pull Test Equipment
    Used to measure the strengths of the tab welds on the cells to ensure that the connections last while in use.

  • Final Assembly

    Final Assembly
    At this step all of the pieces are put together in the final assembly. These can include printed circuit boards, thermistors, membrane switches and many other products depending upon the features of the battery pack.

  • Custom Testing Equipment and Procedures

    Custom Testing Equipment and Procedures
    Battery testing is done on battery packs at both the prototype and production levels. Our in-house capabilities allow us the ability for programming and testing that may be required at the customer level.

America's Oldest. A History of Innovation.

Today at Epec, the customer comes first, and everything we do must be put through that filter. Whether it is developing e-commerce platforms to make it easier to work with us, or creating a NPI (new product introduction) process that helps our customers get to market faster, or the other 10 new projects we have in process, we must focus on building the new. By doing that every day, and by always making the customer our top priority, we plan on being here for another 65 years and then some.
