Reliable heavy-duty power switching demands optimal material integrity. Our custom components for automotive relay for power switching are manufactured using:
-
High-Conductivity Copper Alloys: Premium phosphor bronze with nickel or tin plating to ensure minimal contact resistance and prevent thermal runaway.
-
Industrial-Grade Stainless Steel: Grade $SUS304$ or $316L$ for high-vibration and corrosive automotive environments, ensuring mechanical longevity.
Advanced CNC Turning & Precision Grinding Process
At Caiyi, we utilize top-tier CNC turning, precision grinding, and electrochemical polishing to achieve strict automotive-grade tolerances. The stepped interfaces and cylindrical shapes are crafted with a precision-machined bore for seamless pin insertion or threaded connections. Our polished surfaces guarantee an ultra-smooth finish that enhances coating adhesion and prevents micro-arcing during high-voltage switching.
Fully Customizable Dimensions & Form Factors
We understand that every automotive electronic control unit (ECU) or power distribution box has unique layout constraints. Our manufacturing setup accommodates a versatile size range tailored to your blueprints:
-
Diameter Range: $\Phi8\text{mm} – \Phi25\text{mm}$ (fully customizable)
-
Height Range: $10\text{mm} – 40\text{mm}$ (fully customizable)
-
Internal Layout: Options for internal threads, blind holes, or custom stepped geometric interfaces.
Strict QA & Automotive-Grade Compliance
As a trusted automotive hardware manufacturer, Caiyi maintains rigorous quality control protocols. Every batch undergoes layer-thickness testing for the nickel/tin plating to guarantee maximum anti-oxidation and excellent solderability, making our parts ideal for high-current automotive relays, starters, and new energy vehicle (NEV) power management systems.
