Copper

Today, the use of copper is extremely high due to its versatility and exceptional physical and chemical properties. This metal plays a crucial role in countless economic and industrial activities and is considered a strategic resource in sectors such as automotive, electrical, industrial manufacturing, and construction. Its high conductivity, corrosion resistance, and mechanical strength make it indispensable in the design and production of modern components.

At Sumiparts SAS, we have extensive experience and technical capacity in copper engineering processes, guaranteeing precision, efficiency, and quality in every stage of production. Below are the main processes we develop with copper and its alloys:

CNC Machining 

Our CNC machining process is carried out under the concept of fast dry machining, using air cooling when necessary. This method provides high precision, superior surface finish, and reduced production costs, making it the optimal choice for complex copper projects that require both dimensional accuracy and consistent quality.

Copper Welding

We perform copper welding using both soldering and brazing techniques, depending on the application and thickness of the material. These methods preserve the metal’s electrical and thermal conductivity, ensuring strong, clean joints that meet the highest industry standards. Our specialized procedures guarantee reliability and performance in every welded component.

Punching and Stamping 

Copper sheets and their alloys are ideal for punching and stamping operations thanks to their excellent ductility and machinability. At Sumiparts, we execute precise engravings, complex geometries, and holes with tight tolerances and repeatable accuracy, adapting to the requirements of each design.

Laser Cutting

Our laser cutting technology is the most recommended option for copper projects that demand tight tolerances, clean edges, and intricate geometries. This process offers high cutting speed, excellent productivity, and outstanding finishing quality, making it the preferred solution for mass production and high-performance applications.

Bending and Forming

We apply specialized bending and forming procedures, carefully analyzing the grain direction at the microscopic level to maintain the structural integrity of the material. This ensures that each copper part retains its original mechanical and conductive properties, even after deformation.

Finishes

Given copper’s excellent electrical conductivity, proper finishing is essential to ensure safety and durability. At Sumiparts, we protect copper surfaces with insulating coatings and protective layers such as rubber or polymeric materials. This process prevents corrosion, enhances electrical insulation, and guarantees optimal performance in every industrial environment.
