Product Features
Low Contact Resistance: Manufactured using high-purity silver-based materials and precision composite processes, effectively reducing contact resistance, energy loss, and temperature rise.
Excellent Arc Resistance: Optimized alloy ratio and microstructure allow it to withstand arc impacts from frequent switching, reducing material burn-off and extending service life.
Good Anti-Welding Capability: Different material solutions are developed for medium-to-high load conditions, effectively reducing the risk of contact welding and adhesion, and improving equipment reliability.
Stable Electrical Performance: Strict raw material control, heat treatment, and online testing ensure consistent performance between batches, meeting long-term stable operation requirements.
Suitable for Automated Assembly: Precision cold heading and CNC machining processes ensure consistent product dimensions, facilitating automated high-speed assembly production.
Custom Development Support: Customized product solutions can be provided based on operating current, voltage level, electrical life, and installation structure requirements.
Manufacturing Process
Raw Material Inspection: All raw materials undergo chemical composition analysis, conductivity testing, and batch management to ensure stable and reliable material quality.
Alloy Melting: Vacuum melting or protective atmosphere melting processes are used to improve material purity and microstructure uniformity.
Contact Material Preparation: Powder metallurgy, internal oxidation, melt infiltration, or composite processing techniques are employed depending on the material system to achieve excellent electrical properties.
Cold Heading: Rivet structures are machined using high-speed cold heading equipment to improve dimensional consistency and production efficiency.
Precision Machining: Key dimensions and surface quality are controlled through turning, grinding, and polishing processes.
Heat Treatment: Annealing processes are implemented based on material characteristics to optimize conductivity and mechanical properties.
Online Inspection: Dimensional inspection equipment, vision inspection systems, and resistance testing equipment are used to monitor key indicators throughout the process.
Cleaning and Packaging: After ultrasonic cleaning, materials are delivered in anti-oxidation packaging, moisture-proof packaging, or customer-specified packaging.
Quality Assurance System
Chemical Composition Analysis: Verifies that the raw material composition meets technical requirements.
Metallographic Structure Testing: Assesses the uniformity and internal quality of the material's structure.
Contact Resistance Testing: Tests the stability of the product's electrical conductivity.
Anti-Welding Test: Assesses the material's resistance to adhesion under electric arc conditions.
Electrical Life Testing: Simulates actual operating conditions to verify the product's durability.
Dimensional Inspection: Uses automated inspection equipment to control critical dimensional tolerances.
Batch Traceability Management: Enables full traceability of raw materials, production processes, and testing data.
