Product Introduction

The automotive aluminum alloy door lock components are specially designed for the lightweight and high safety of modern automobiles. They are made of high-strength aluminum alloy and processed by precision CNC technology to create high-precision and fatigue-resistant core lock body components. Covering key components such as door lock housings, ratchets, plates, and transmission rods, it is compatible with fuel vehicles, new energy vehicles, and special vehicles, meeting the requirements of automotive-grade strength, weather resistance, and functional integration, and providing reliable solutions for door systems.

Product Parameter

Product Name: Automotive Aluminum Alloy Door Lock components

The product material is 6061-T6/7075 aviation aluminum

Product specifications support non-standard customization

The product processing method is CNC precision processing

Surface treatment: anodizing or electrophoretic coating

Product Feature And Application

Lightweight and high-strength structure

It adopts 7075/6061-T6 aviation aluminum material, with a tensile strength of ≥550MPa. Its weight is 35%-45% lower than that of traditional zinc alloy, reducing the energy consumption of the car door.

Precision CNC process

Four-axis and five-axis CNC machining ensures that the accuracy of key mating surfaces is ±0.02mm, guaranteeing smooth meshing between the lock tongue and the lock buckle and eliminating the risk of jamming.

Extra-long durability

It has passed the 200,000-cycle opening and closing life test, with a dynamic load of ≥1500N and a wear-resistant coating hardness HV of ≥600.

Adaptability to harsh environments

Micro-arc oxidation/hard anodizing treatment, salt spray resistance ≥2000 hours (GB/T 10125), operating temperature -50℃ to +120℃.

Intelligent function integration

Supports modular design such as motor installation positions for electric door locks, keyless entry into sensor slots, and anti-pinch hand safety mechanisms.

Application scenarios

Passenger vehicles: Electric door lock systems for sedans/SUVs, hidden door handle lock bodies.

Commercial vehicles: High-load door locks for heavy-duty trucks, low-temperature special lock cores for refrigerated trucks.

New energy vehicles: Electronic child lock, automatic locking mechanism for charging ports.

Special vehicles: Bulletproof vehicle door locks, military vehicle shock-resistant lock bodies.

High-end models: Frameless door invisible locks, intelligent welcome lighting integrated components.

FAQ

Q1: Can the components of aluminum alloy door locks meet the anti-theft safety requirements?

A: Made of 7075-T6 material and featuring an anti-prying structure design, the lock tongue has a shear strength of ≥800MPa, complies with UL 437 anti-theft certification, and can be integrated with an electronic anti-theft chip slot.

Q2: Can a damp environment cause the lock body to get stuck?

A: The micro-arc oxide layer isolates water and oxygen penetration. Combined with the self-lubricating bearing design, it has passed the 85℃/85%RH damp heat test for 2000 hours without any abnormalities.

Q3: Is the cost of CNC machining much higher than that of die-casting?

A: For small-batch orders (< 1000 pieces), CNC is more cost-effective (no mold fee). For large quantities, the die-casting +CNC composite process can be selected, reducing the unit cost by 40%.

Q4: Can it be compatible with the original vehicle lock core and the electronic control system?

A: Support customizing key tooth shape codes and motor-driven racks according to the original vehicle interface to ensure signal matching with the BCM (Body Control Module).

Q5: Is surface color customization available?

A: Supports anodic oxidation coloring (black/gray/gold), sandblasting matte and other treatments, with a color difference ΔE≤1.0 (conforming to the GSB international color card).

Q6: What is the minimum order quantity (MOQ)?

A: CNC process requires a minimum order of 1 piece, and die-casting process MOQ requires 1,000 pieces. We support mixed model production to reduce inventory pressure.
