Aluminum die-casting finished product assembly process

The assembly process of aluminum die-casting products is usually a subsequent process after die-casting manufacturing is completed. The assembly steps are described as follows:
 

Pre-treatment of die-casting products

Deburring and trimming
 
Remove the flash, burrs, and gates on the surface of die-casting products.
 
Use a deburring machine, hand tools, or polishing to trim the appearance.
 
Check the size and appearance
 
Check whether the dimensional accuracy meets the standard.
 
Check for defects such as pores, cracks, and deformation.
 
Surface treatment
 
Sandblasting, anodizing, spraying, powder coating, etc. are performed as required.
 
Improve the appearance quality and corrosion resistance.
 

Parts preparation

Other accessories processing
 
If the finished product needs to be combined with other parts such as plastics, rubber, screws, circuit boards, etc., it needs to be processed and prepared in advance.
 
Prepare screws/nuts/washers, etc.
 
Prepare all the required hardware, wires, seals and other assembly materials.
 

Assembly work

Mechanical or manual assembly
 
Use screws, rivets, tenons, glue, welding and other methods to combine die castings and other parts.
 
Arrange the assembly sequence according to the design drawings.
 
Precision alignment and locking
 
Use jigs to assist alignment to ensure assembly accuracy.
 
Control the torque when locking the screws to avoid over-tightening or over-loosening.
 

Post-assembly testing and inspection

Functional testing
 
Test mechanical, electronic or airtight performance to confirm normal function.
 
If there are electrical components, power-on testing is required.
 
Appearance and structural inspection
 
Ensure that there are no scratches, stains, or defects on the surface.
 
The structure is firm and not loose.
 

Packaging

Cleaning and protection
 
Clean the surface oil and apply dust bags and anti-collision foam when necessary.
 

Packaging and labeling

Classify and package according to item specifications, and mark the product name, batch number and quantity.
 

Shipment

Store or ship to customers, subsequent assembly lines or final assembly lines.
