Product Description Technical information Engineering difficulty

Metal enclosure used in semiconductor controller

1. Material: Aluminum
2. Surface treatment: Oil painting and silk screen
3. Process: Laser cutting and bending --- Riveting ---Brushing --- Oil painting --- Silk screen

1. Need exactly 90 degree angles in corners;
2. Matt Fine Texture, it's made manually, matt size should be symmetrical;
3. Can't paint the inside of the box;
4. Straight strictly on the edge.
5. No scratch at all.

Aluminum Metal box used in power supply

1. Material: SUS and aluminum
2. Surface treatment: None and anodizing
4. Process: Stamping---Punching holes--- Anodizing

1. The aluminum enclosure has many convex and hump, easy to break if tooling is not so good;
2. Stainless steel cover has over 200 holes, meanwhile, the edge between holes are only 0.5mm; easy to break or generate burrs;
3. These two parts should assembly exactly.

SUS metal cover used in construction

1. Material: SUS
2. Surface treatment: Brushing
4. Process: Laser cutting and bending --- Riveting ---Plant bolts --- Welding --- Brushing --- Pickling --- Laser etching

1. 3.5mm stainless steel, hard material, difficult to fabricate;
2. The part should pass 168H salt spray testing;
3. When the bolt is planted, can't be visible on the other side surface, meanwhile when standing 350N strength, the bolt won't fall off;
4. Welding and laser cutting mark should not be visible;
5. No burrs, no sharp edges, smooth feeling when touching;
6. Brushing lines should exactly be parallel, very straight and cannot be distorted;
6. After variety of manufacturing processes, final surface not allow any scratch, stamp or bumps.
