Heyiarbeit 20mm OD 10mm ID 40mm Long Spring Steel Spiral Stamping Die Spring - Medium Load Compression Mold for 3D Printers (Red, 1PCS) - Perfect for CNC Machines, Industrial Presses & DIY Projects

Die Spring Characteristics The loading grade of die springs in various colors (from lightest load to extra heavy load): yellow, blue, red, green, brown; In addition, because die springs are well suited for high stress applications, they are also suitable for a variety of other applications as well. Feature 1. Made of Spring steel material, the surface is painted, not easy to rust, more durable. 2. Die springs are harder than ordinary springs, and their durability is better than ordinary springs, which helps 3D printers print more stably. 3. The diameter of the hole on the Mold, that is, the outer diameter of the spring. The diameter of the rod that is to be inserted into this spring, that is, the inner diameter of the spring. Die Spring are more stiffer, keeps print bed lever better! Quick and Easy Installation Unscrew the adjustment knobs from the bottom of your print bed.And replace those stock springs with these new ones.Screw the adjustment knobs back into the print bed with these new springs.Then you're free to go! Level your bed and keep on printing! High-quality Steel: High Hardness, Not Easy to Deform Compression Die Springs are made of spring steel, which has the characteristics of fatigue resistance and good toughness. Professional Design: Stress Concentration During Springback The shape of the compression spring is in the shape of a rectangular section with rounded corners. It is designed by professional engineers and uses space meticulously, which can reduce the stress concentration of the spring when it is squeezed and rebounded at high speed. Surface Strengthening: Extended Service Life The surface of the spring is strengthened to make the surface structure tight, improve the strength of stress concentration, and prolong the service life of the spring. High Pressure Treatment: High Quality and High Frequency After more than three times of strong pressure treatment, the internal stress before use is eliminated, and the deformation, shortening and breaking of the spring are avoided. Application Compression Die Springs are widely used in stamping die, metal diecasting die, plastic die and other elasticmotion precision mechanical equipment, automotive field. Mold springs are harder than regular springs, which helps your 3D printer be more stable when printing. Die springs are primarily used in die machinery, for plastic injection. Because die springs are well suited for high stress applications, they are also suitable for a variety of other applications as well.
