1. The importance of product accuracy. Error in accuracy may be a problem with the rollers design of ppgi aluminum c purlin roll forming machine, or the debugging is not perfect, especially if the design is unreasonable, it is difficult for the after-sales debugging personnel to deal with it later,because it involves the change of the rollers.
2. Acceptance of roller material. The material of the roll is the main component related to the life of the equipment, especially the customized c z purlin roll forming machine , the roller is easy to wear, and once it is worn and needs to be replaced, it is a big project. If the roll forming machine from china manufacturer does not use the roller material according to the standard, the quality of the equipment is difficult to guarantee.
3. Acceptance of frame materials. If the material used is not contract, the equipment is easy to deform, affecting the accuracy of the product produced, or it has been seriously deformed during transportation.Our frame is welded by 400# H-shaped steel. The H-shaped frame and the design of the inclined strut and bolster increase the strength of the frame,which are important factors in keeping the frame stable and reliable.
4.Inspection of the material of shearing device. The cutter is very easy to wear, and a high standard of material should be used.Otherwise in the later production, it is easy to break,or not sharp enough for a few days of production.
5. Acceptance of cutting and punching rough edges. If the raw edge is too serious, it will affect the sales of the product produced by stud and track/drywall/c channel/main channel/wall angle frame roll forming machinery. Such problems can be found and dealt with in a timely manner in the factory.
6. Brand and quality of electrical components. This involves the stability of the circuit in the future, such as the brand of PLC, the brand of inverter, relays and so on.
