Frequently Asked Questions (FAQ)
Q1: What file formats do you accept for laser cutting?
We accept .dwg, .dxf, .step, .igs, .pdf, and .ai files. Our engineers can also convert your 2D/3D drawings into suitable cutting programs.
Q2: Can you fabricate parts from both stainless steel and aluminum in one order?
Absolutely. We handle mixed-material orders and can weld stainless steel to aluminum using specialized transition inserts (bimetallic strips) if required.
Q3: What is the minimum order quantity (MOQ) for custom steel box parts?
For prototypes, MOQ is 1 piece. For mass production, typical MOQ is 100 pieces, but we are flexible — please contact us with your quantity.
Q4: Do you provide surface treatment like powder coating or anodizing?
Yes. We offer powder coating (any RAL color), anodizing (clear or dyed), sandblasting, and brushing. We can also match your existing color.
Q5: How do you ensure the welding quality for aluminum parts?
We use pulsed MIG welding with argon shielding, pre-cleaning, and proper filler wire (e.g., ER5356). Weld strength is tested by tensile samples per your specification.
Q6: What is your typical lead time for a 500-piece order of steel boxes?
After drawing approval, production takes 20–25 working days. Express delivery can be arranged for an additional fee.
Q7: Do you offer any warranty on your fabrication work?
Yes, we provide a 12-month warranty against defects in material and workmanship. Any non-conforming parts will be replaced or reworked at no cost.
Q8: Can you produce parts according to our specific tolerance requirements stricter than ±0.1mm?
Yes, we can achieve ±0.05mm on laser cutting and ±0.2mm on welding assemblies. Please specify your tolerance on the drawing.
