How we do
1. Roughness :
A good roughness for aluminum enclosure or aluminum housing, it not only requie a high precision CNC machines but also ask very rich experience.
Our factory have 6 years experience on custom aluminum parts, continuous accumulation of machining experience, below are photos for reference.
2. Package:
We use EPE foam or vacuum package to protect aluminum surface very well.
Also we will wrap them during aluminum CNC machining process to avoid any damage.
Machining Process
Our main process is Raw material incoming – Machining – Secondary process – Surface treatment – QC report – Package & Shipping , please check below more details.
Our main machines in workshop are high-speed CNC machines with 3 axis and 4 axis, all cutting tools and machines are service for alumunim material, we have the strong advantage than other suppliers.
This is our CNC aluminum milling video for reference, you can have a look.
Quality Control
Our QC team have 3~4 workers, main test instruments are 2.5D, 3D CMM , Roughness instruments and Hardness instruments.
100% inspection before shipping including material checking, dimensions inspection, roughness checking, hardness checking and appearance checking.

Below custom aluminum parts were made for some customers before, they are all not confidential..
But there are still lots of nice and complicated parts can’t be able to show as they are secret to customers, we signed the NDA agreement to protect it.
