Whatever you want to call it…

We Believe In Do-It-Yourself

From prototype to production, our complete production facilities have the capability to produce your products 100% in-house.

This includes extruding our own wire & cable, cutting our own tools, and having Engineering, R&D and compliance experts on staff.

Having a complete Tool Shop onsite at each production facility means we’re able to swiftly address any tooling needs that arise. Whether it’s creating tooling for quick prototypes or cutting full production-scale tooling for large runs, our tool shops can handle it all.

In addition, key tooling is duplicated at each site to minimize downtime and ensure quick response to your needs.

DSM&T carries approvals to produce the most common types of wires and cables, such as UL 1007/1015, SJT’s and SPT’s.

This ensures consistent lead times, competitive pricing and top quality.

With a combined 60 years of interconnect experience, our R&D department provides quick and customized solutions. Whether you need a Custom Connector, need to find alternate components, or desire electrical interconnect guidance, our R&D team can help.

UL is part of our DNA. In addition to researching and designing our in house products to UL standards, our UL specialists can guide you through your UL journey, ensuring a quick and efficient application process.
