What are Electrical Contacts Stamping Brass Parts Custom?
Electrical Contacts Stamping Brass Parts Custom are manufactured from brass sheet or strip through precision blanking, punching and forming processes. Brass provides a conductive base material with the ductility required for terminal profiles, socket contact structures, and connector components. For assemblies requiring additional contact elements, stamping and riveting can be integrated into the production sequence. Component geometry, material grade, thickness, hole positions and riveting locations are defined by approved customer drawings. Factory production supports custom development, OEM manufacturing, and wholesale orders for electrical socket switches, plug terminals and connector assemblies.
Core Manufacturing & Technological Advantages of Switches and Sockets Brass Copper Terminal
Precision Stamping Technology
High-speed press lines operating at up to 600 strokes per minute utilize multi-stage progressive carbide dies to stamp complex contact geometries. Strip feeding mechanisms maintain pitch accuracy within ±0.005 mm, preventing edge burrs and edge-curvature distortion on high-volume production runs.
Integrated Stamping-Riveting Process
Automated in-die riveting technology feeds silver alloy contact tip rivets directly into the stamped brass substrate during the primary stamping pass. This eliminates separate secondary assembly operations, maintaining joint shear strength above 120 MPa while avoiding oxidation layer formation between the rivet and the brass blade interface.
Automated Production & Continuous Improvement
Real-time tonnage monitoring integrated into every stamping press detects punch wear or material thickness deviations instantly, mitigating micro-cracking risks during sharp bend formations. Closed-loop servo feeders systematically adjust coil advancement rates to eliminate strip slippage, keeping overall scrap rates below 0.3%.

Frequently Asked Questions about Metal Brass Terminal Contact
How do you prevent stress corrosion cracking (SCC) in Electrical Brass Terminal Contact Accessories?
+
-
We apply thermal stress-relief annealing post-stamping at controlled temperatures (250°C–300°C) to eliminate internal residual stresses induced during severe forming operations, neutralizing SCC susceptibility in humid or ammoniacal service environments.
Can your facility integrate silver contact tip riveting directly inside the stamping die?
+
-
Yes, our progressive dies utilize automated in-die riveting units that feed, insert, and stake solid or bimetal silver contact rivets directly into the brass strip during continuous press operation, maintaining joint shear strength above 120 MPa.
What is the achievable burr height limit on your Electrical Switch Socket Brass Terminal Contact Stamping Parts?
+
-
Using high-precision carbide dies with punch-to-die clearances maintained between 5% and 8% of sheet thickness, we consistently control maximum burr height to under 0.015 mm across production runs.
How do you ensure lot-to-lot consistency in spring retention force?
+
-
We enforce strict tensile strength (±20 MPa) and Vickers hardness (±5 HV) acceptance bands on incoming raw material coils. Furthermore, automated spring-back compensation in die tooling maintains bending angle tolerances within ±0.5 degrees.
What are the standard lead times for custom tooling and initial production samples?
+
-
Standard progressive die design, fabrication, and sample submission require 10 to 15 working days. Upon sample approval, mass production lead times typically range from 10 to 15 days based on order quantity.
