What is the return material for a metal strip cutting machine? What are the methods for returning material in a metal strip cutting machine? Let's learn about it together below.

Rubber Ring Scraping Method. This technique is commonly used for thicker materials or wide strip finished plates.

Typically, the material return O-rings used are mainly made of oil and wear-resistant rubber, such as polyurethane, also known as Urethane, among others. Another commonly used rubber is nitrile rubber.

The choice of these materials is primarily due to their high wear resistance, strong oil resistance, excellent corrosion resistance, and good deformation recovery capabilities. In actual production, adjustments to the hardness are made based on the type of material sheared by the metal strip cutting machine, taking into account the thickness and texture of the cut sheets for the manufacturing of the component.

Generally, the hardness range should be maintained between 60 to 90 degrees. Additionally, attention must be given to the reasonable selection of the gasket's size. The gasket size is primarily determined by the blade's dimensions and the blade separator's size, which dictate the inner diameter.

That is to say, when processing sheets with the metal striping machine, selecting the appropriate return rubber ring based on the thickness of the sheet is essential to ensure the smooth appearance and surface quality of the finished strips.

Another method of unloading material for metal strip cutting machines is called panel unloading. Currently, the unloading boards most commonly used are made of harder materials like bakelite and red-stained solid wood, with an additional layer of anti-scratch material applied to the surface.
