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 and In bulk.

After-sale-service:

1. The Seller has passed ISO9001 quality system certification since 1997, and always execute strictly this quality
management system in our company and on our products.

standard.
2. Warranty is one year since the date of B/L, or final acceptance date of heavy duty machinery. Longer warranty
could be purchased by the user.
3. Commissioning: For heavy-duty machinery, the Seller sends technicians (electrical hydraulic & mechanical)
to guide the installation, testing and training the operators from 7 days to 45 days after the machine
reaches the factory of user. But the round-trip air tickets, local accommodation and allowance
(USD100/person·day) in the User's country will be burdened by the Buyer. The above charges do not be
included in the offer. This clauses will be shown in the contract.
