Production technological process
Steel plate to warehouse →physical & chemical inspection→ steel plate ball blasting (dustproof) processing → cutting through CNC flame cutting machine → cutting and processing to each welding junction plane → compound welding→ Air protecting welding → Stress relief by electrical furnace →processing through heavy-duty floor type boring and milling machine, heavy-duty gantry milling machine → Fabrication.

Packing: Coating with anti-rust oil on working surface, with plastic film layer for whole machine. Packed in container or in bulk.

After-sale-service:
1. The Seller has passed ISO9001 quality system certification since 1997, and always execute strictly this quality
