Stremet has been collaborating with clients in the electronics industry since the company’s inception. Copper is a familiar material for us, and we specialize in both copper piercing and laser cutting. We can pierce copper from 0.5 mm up to 2 mm thickness, and for thicker copper sheets, we utilize laser cutting up to 6 mm thickness. Copper is commonly used in electrical conductors within the electronics industry. In addition to copper, we also offer punching of Bakelite (which is a typical insulating material used in the electronics industry) as well as manufacturing of electrical cabinets from sheet metal for this customer segment.

Copper is a highly expensive material, which is why minimizing waste during its processing is crucial. Due to the toughness of the material, expertise in tool selection is required for copper punching. We have a dedicated punch press for copper piercing, where tooling and clearances are optimized for this specific purpose.

Copper laser cutting is challenging due to the material’s reflectivity, and it’s not widely offered due to the inherent risks in the process. Laser-cut works are typically laser cutted busbars, serving as an alternative to using copper bars. With laser cutting, we can give the conductor a shape that allows it to fit better into any electrical cabinet compared to rectangular flat pieces. We also create straight parts with flat shapes. We offer various options for copper coating as well.
