Machine Made Sheet Quality Control Inspected by engineer and sales with the standard of size on the signed profile drawing. Final-inspection by clients on site or by video or pictures. --Customer's recognition for machines and sheets are the basic principles.

Machine Frame Using planer milling machine to process surface of machine frame to improve the flatness. Good flatness frame ensure all the wall plate can be installed in the same level. It is extreme important to the final steel products.

Stocking System Customized Machines Roll forming industry is a non-standard industry, all machines are produced newly according to different client requirements. There are no stocking machines or second-used machines for sell.

Rollers Every rollers use CNC machine to polish and machining into designed rollers shape, it can improve rollers accuracy. Main Roller Material: No.45 steel rollers are plated 0.05mm hard chrome to improve the hardness. Having bearing inside the rollers to make machine run with less loading so that rollers not easy to damage. • Ensure the same speed between the rollers, no speed difference between rollers, improve the forming accuracy. • Bearings are helping to prolong machine life.

Toroidal bearings: Add into the wall, reducing friction during the rotation of the shafts to ensure longer machine lifespan.

Cutting Blade Using high quality Cr12 Mov steel to ensure good mechanical behavior while cutting. It is being wire cutting to ensure cutting blade has high precision. Being polish in the plane grinding machine to remove the rags on the cutter and get high flatness.

Shaft Solid steel shafts are being tooling twice with grinding machine to ensure final precision.

Services to Customers --Spare Parts 1) Machine will be delivered with one free cost spare parts box. Normally, these spare parts are enough for machine running in 2-3 years. 2) Within the warranty, Zhongyuan will send a new onefreely to customer in the shortest time if confirm not man-made damage. Out of warranty, Zhongyuan will send a new one in the shortest time after client pays spare cost. 3) Saving whole machine design drawings lifetime, Zhongyuan can response immediately to make a new spare parts as saved data. --Just tell your spare parts requirement, Zhongyuan can supply accurate one, no matter how old your machine is.
