How does the clamping system ensure welding quality?

The pneumatic key pressing plates automatically eliminate gaps of longitudinal seam assembling and compress the workpiece evenly to prevent distortion.

What is the lead time for production?

The average lead time is 1-3 months during the off-season and 3-6 months during the peak season.

What payment terms are accepted?

We accept LC, T/T, D/P, PayPal, Western Union, Small-amount payment, and Money Gram.
