Products Description
Relay Brass Stampings are not merely physical supports, but also complex conductive mechanisms. Our products possess the following key characteristics:
Multi-dimensional geometric consistency: Utilizing a multi-station progressive die process, we ensure that the dimensional tolerances of each batch of parts remain at the micron level, even under complex bending and folding designs.
Excellent elastic return performance: Particularly for relay springs and contact supports, precise springback compensation design ensures that parts maintain their original contact pressure after millions of physical cycles.
Outstanding surface physical properties: The stamped parts have a smooth surface, free of microcracks or stress marks, which is crucial for subsequent electroplating (such as gold, silver, or nickel plating) and precision welding.
Material Advantages: A Perfect Blend of Scientific Proportions and Electrical Performance
Carefully Selected Grades (e.g., C2680 / C2600 / C2801)
We offer brass options with varying zinc contents to suit different application scenarios. The high-purity copper matrix ensures extremely low resistivity, effectively reducing temperature rise during high-current applications.
Controlled Grain Size
Through rigorous screening of raw material annealing conditions, we ensure our brass exhibits excellent ductility during stamping. This means that even with bending at 90° or more complex angles, grain boundary fractures will not occur at the material edges, guaranteeing the structural integrity of the parts.
Anti-oxidation Protection
All Brass Contacts Crimp Terminal Block Assembly For Socket Switches undergo anti-oxidation passivation treatment before leaving the factory, ensuring that no oxide scale will form due to contact with air during storage and assembly, thus preventing impact on conductivity or weld strength.
Production Process: The Transformation from Coil to Premium Products
| Material Warehousing and Inspection | Incoming brass strip undergoes rigorous hardness and tensile testing, compositional spectral analysis, and dimensional tolerance inspection to ensure source control. |
| Precision Progressive Stamping | On a high-speed Brass Metal Stamping Parts Electrical Accessories Components press, the strip is fed into the die at a frequency of 100-500 times per minute. Through dozens of continuous stamping steps, the metal undergoes instantaneous plastic deformation, forming the parts. |
| Cleaning and Degreasing | Environmentally friendly industrial cleaning agents are used for multiple ultrasonic cleaning processes to thoroughly remove Sheet Metal Brass Stamping oil and fine metal shavings, ensuring clean, oil-free parts that meet stringent electrical insulation requirements. |
| Heat Treatment (Annealing) | For severely work-hardened parts, bright annealing is performed to eliminate internal stress, restore material toughness, and prevent brittle fracture during subsequent use. |
| Surface Treatment (Optional) | Tin plating, silver plating, nickel plating, or passivation treatments are performed according to customer requirements to enhance conductivity or corrosion resistance. |
| Final inspection and packaging | Random sampling is conducted using a 2D image measuring instrument, height gauge, and micrometer, and full inspection is carried out in conjunction with calipers. Finally, vacuum packaging or moisture-proof packaging is used to ensure that the product does not oxidize or suffer physical damage during transportation. |
Detail Showcase: Quality Revealed in the Tiniest Details
Edge Quality
Under a microscope, the Electrical Contact Stamping Brass Parts Customs exhibit sharp, clear edges with no tear layers or visible burrs. The surface feels smooth to the touch, without any sharp edges – a testament to the precision of the molds and high-precision stamping.
Bending Angle Transition
Bending angles are smooth and seamless, without cracks. The material's fiber structure remains continuous and fluid, ensuring that even under repeated stress, these stress concentration points remain resilient.
Hole Wall Smoothness
The inner walls of the punched holes are bright and flat, without taper deviation, ensuring smooth insertion of rivets or wires and maximizing contact area.
Surface Texture
The characteristic golden yellow color of brass is uniform and consistent, without oxidation discoloration, water stains, or indentations. For Brass Sheet Metal Stamping Parts requiring subsequent electroplating, this perfect surface substrate is a prerequisite for obtaining high-quality plating.
