Preferred material

CNC Machining Aluminum uses high-purity aluminum water rod as raw material, which has stable performance, high toughness, and easy processing

Flat cut

The company is equipped with large cutting machines, shearing machines, sawing machines, and leveling machines

Surface treatment

It is treated with fine processes such as chemical technology polishing, anodizing, spraying, fluorocarbon, etc., and the appearance is bright and the feel is comfortable and smooth

Size/Specifications

The design of dimensions and specifications needs to accurately match the thickness, length and installation scenario, with the core goal of ensuring firm, flat and easy adjustment.

Virgin aluminum

1. Raw material source:It is extracted from aluminum ore and extracted pure aluminum through an electrolyzer.

 

2.Production process: The production process is complex and requires a lot of electricity and fuel, and the production of 1 ton of virgin aluminum requires about 13-14 megawatt-hours of electrical energy.

 

3.Performance differences: Strength, hardness, toughness, and oxidation resistance are stronger, and the service life is longer.

Recycled aluminum

1. Source of raw materials: It is recycled from waste aluminum products (such as waste car parts, cans, etc.) and re-smelted.

 

2.Production process: Recycled aluminum: The production process is relatively simple and consumes much less energy.

 

 

3. Performance difference: its performance is slightly inferior, impurities are easy to rust, rough and dull, easy to deform and break and short life

The inspection process of CNC machined aluminum alloy products can be simplified into three major links to efficiently control quality:

1. Incoming material inspection
Check the aluminum alloy grade (such as 6061, 7075) and heat treatment status, check the hardness and size (thickness/diameter deviation ≤± 0.1mm), and check for surface cracks, oxidation spots and other defects to ensure raw material compliance.

2. Process inspection
The first part must be inspected for full size (use three coordinates to measure the key dimensions, tolerance within ±0.01mm), shape and position tolerance (flatness ≤ 0.005mm/100mm); Inspect the surface knife pattern and burr between processes, measure the thickness uniformity of thin-walled parts, and correct the processing deviation in time.

3. Finished product inspection
Full inspection of appearance (no scratches, color difference), surface roughness (Ra 0.8-3.2um), sampling and assembly adaptability (such as gap 0.01-0.03mm), additional inspection of internal defects of key parts (ultrasonic flaw detection), classification of unqualified products for rework or scrapping, the whole process can be traced.
