With the development of the sheet metal industry, users have higher and higher requirements for the surface quality of sheet metal parts, especially stainless steel parts and aluminum parts. Higher aesthetics can improve the product's grade and price, and improve the company's brand image, especially for the bending of stainless steel plates and aluminum materials, requiring no scratches on the surface.
Ordinary traditional process solutions: 1. Increase the'V' opening fillet of the bending lower knife, although the effect is improved, but still can not change the scratch; 2. Pad rubber on the bending knife, but the life of the rubber very short.
The bending protection film has been verified by customer experiments, in addition to ensuring the surface quality, it also greatly improves the service life. The bending protective film acts as a buffer between the work piece and the corners of the lower mold, so as to prevent the work piece from producing indentation during bending. It is only necessary to spread the bending film on the lower mold during use.
Bending protective film specifications:
①30M*110MM*0.6MM ②30M*150MM*0.6MM For general thickness
③30M*110MM*1.0MM ④30M*150MM*1.0MM for extra thick plate
⑤30M*110MM*0.3MM ⑥30M*150MM*0.3MM For ultra-thin plate thickness
Color: transparent and milky white
Durability: Regarding product durability, the durability varies according to different plates and thicknesses. For details, please contact customer service.
Example: ① paragraph
Bending 3MM aluminum plate, each stress point, durability is about 5-600 knives
Compared with ordinary plastics, the anti-indentation protective film for bending has the following properties:
1. Strong wear resistance
2. Strong tear resistance
3. Excellent bending performance
4. High tensile strength and elongation at break
5. Resistant to low and high temperatures
6. Long-term compression deformation rate is low
7. Resistant to oils, lubricants and aliphatic hydrocarbon solvents
8. Resistance to oxygen and ozone oil, anti-aging properties
