Main application scenarios?
A: General formed parts such as appliance casings, furniture, sheet metal parts, brackets, non-load-bearing structures, and galvanized substrates.
Can SPCC be used for deep-drawn parts?
A: Yes, for small deformations; however, large deformations and complex shapes are prone to cracking. SPCE should be preferred, and the n/r value and annealing quality should be confirmed.
How to prevent rust after welding?
A: Clean spatter and weld slag; apply zinc-rich paint or touch up the weld and heat-affected zone; overall coating is recommended if possible.
Common causes of stamping cracks?
A: Material hardness too high/insufficient elongation, die radius too small/lack lubrication, drawing coefficient too small, inclusions in the material/edge cracks; countermeasures: annealing, optimizing the die and process, and strictly controlling incoming material quality.
How to avoid scratches on inventory?
A: Use layered paper/film, handle with care, and avoid contact with sharp objects; the contact surfaces between shelves and transport vehicles must be smooth.
