Electroplated copper stamping parts have excellent machinability
Stamping is done at room temperature, using the die on the press to
exert pressure on the sheet metal, causing separation or plastic
deformation to achieve a specific shape, size and performance of
the part.Thin, even, light and strong are the characteristics of
punched parts.
Stamping parts have thin, uniform, light and strong
characteristics. Since precision moulds are used in the stamping
parts, the accuracy of the workpiece can reach the micron level,
and the repeat accuracy is high and the specifications are
consistent, so the application of the stamping parts is also very
wide.
Copper stamping parts are widely used because of their excellent
electrical conductivity and wear resistance.
Our company offers a full range of services from materials to
finished parts and helps many companies produce precision copper
parts and meet their surface quality, accuracy and tolerance
specifications.
- Electrical Contacts: Copper stamping parts are widely used in
electrical connectors, switches, relays, circuit breakers, and
other electrical devices. The high conductivity of copper ensures
efficient electrical current flow, while the stamping process
allows for the creation of intricate contact designs.
- Automotive Components: Copper stamping parts are found in various
automotive components, including fuel system components, electrical
connectors, terminals, and sensor housings. Copper's electrical
conductivity and corrosion resistance are beneficial in automotive
electrical and electronic systems.
- Terminals and Connectors: Copper stamping parts are employed in the
manufacturing of terminals and connectors used in electrical wiring
and cable assemblies. These parts
With our advanced technology, our copper profiles can be stamped
according to our customers' drawings to meet their exact
engineering needs.Copper stamping parts are manufactured through a
process called copper stamping or copper sheet metal stamping. This
process involves the following steps:
- Material Selection: High-quality copper or copper alloy sheets are
selected for stamping parts. The specific copper material is chosen
based on the desired properties, such as conductivity,
malleability, and corrosion resistance.
- Die Design and Preparation: A die, which consists of two parts (the
punch and the die), is designed to create the desired shape of the
copper stamping part. The die is typically made of hardened steel
and is customized to match the specific dimensions and features of
the part.Sheet Metal Preparation: The copper sheet is prepared by
cutting it into the required size and shape. This can be done
through shearing or cutting methods such as laser cutting or water
jet cutting. The sheet is then cleaned and deburred to remove any
sharp edges or surface imperfections.
- Stamping Process: The prepared copper sheet is placed between the
punch and the die in a stamping press. The stamping press applies
pressure to the copper sheet, forcing it to conform to the shape of
the die cavity. The punch, which is a hardened steel tool, pushes
the copper sheet into the die, thus forming the desired shape.
- Forming and Bending: In addition to basic shaping, the stamping
process can involve forming and bending operations to create more
complex features or angles. This is achieved by using additional
punches, dies, or bending tools within the stamping press. Multiple
stamping operations may be performed to achieve the final shape.
- Trimming and Piercing: Trimming and piercing operations may be
carried out to remove excess material or create holes and openings
in the copper stamping part.
- Secondary Operations: After the initial stamping process, secondary
operations may be performed depending on the specific requirements
of the part. These can include deburring, surface finishing (such
as polishing or plating), welding, or assembly processes to join
multiple stamped parts together.
- Quality Control: Throughout the manufacturing process, copper
stamping parts undergo quality control inspections to ensure they
meet the required specifications and dimensional tolerances. This
can involve dimensional measurements, visual inspections, surface
quality assessments, and other testing methods.
