Factory Capabilities & Technical Parameters
Our two machining facilities feature over 200 machines, dedicated to custom high-precision automotive and industrial parts.
Product Overview & Advantages
Targeting the specific working environment of automotive oil pump covers, we optimize processes to solve sealing, pressure, and corrosion challenges.
Core Advantages
Exceptional Surface Flatness & Airtightness
Through high-precision CNC milling and grinding, the mounting surface of the oil pump cover is perfectly flat, effectively preventing oil or hydraulic fluid leaks.
Hard Anodizing & Corrosion Resistance
The surface generates a dense aluminum oxide protective film, significantly enhancing the cover's corrosion and wear resistance in high-temperature, oily environments.
Lightweight & High Strength
Using 6061-T6 aerospace-grade aluminum alloy, it significantly reduces the weight of engine accessories while ensuring structural strength, contributing to automotive lightweighting.
Strict Dimensional & Geometric Tolerance Control
For the dual counterbored mounting holes and complex outer contours, strict CMM inspection is implemented to ensure perfect assembly for every batch.

FAQs
Yes. Our commonly used 6061-T6 aluminum combined with hard anodizing can excellently withstand the high temperatures and oil corrosion environments around engines. It is widely used in oil pump covers, timing covers, and other components.
We use high-precision CNC milling machines for machining, followed by surface grinding or fine turning. Combined with a CMM, we strictly control the flatness of the surface (typically within 0.02mm) to ensure absolute sealing after assembly.
We use a comprehensive quality management system. During mass production, we conduct First Article Inspections (FAI), in-process patrol inspections, and use CMMs and dedicated gauges for final full-dimensional inspections.
Absolutely. We support low-volume flexible production. Our Minimum Order Quantity (MOQ) starts from just 1 piece for prototyping, making it perfect for automotive modification R&D or new project testing.
