Product Description Product Description:Introduction to Spring Sheets#### Manufacturing and Technology- ** Bending processing ** : Spring sheets usually need to undergo bending processing during forming. To avoid generating excessive stress, the bending radius should be at least five times the thickness of the plate during the design.- ** Stress concentration ** : Spring plates often have stepped sections and openings. Stress concentration may occur at the stepped sections where the dimensions change sharply. The smaller the diameter of the hole and the wider the plate, the higher the stress concentration coefficient.- ** Heat treatment ** : After being made, spring sheets usually need to undergo heat treatment to enhance their performance. The hardness after heat treatment is generally between 36 and 52HRC.#### Features- ** Structure and Shape ** : Spring plates come in various shapes and structures depending on their applications. They can be classified into two types based on their appearance: straight leaf springs and curved leaf springs. According to the shape of the plates, they can be categorized as rectangular, trapezoidal, triangular, and stage-shaped, etc.- ** Mechanical Properties ** : The spring sheet is prone to bending in only one direction (the plane with the minimum stiffness), while it has a relatively large tensile stiffness and bending stiffness in the other direction. This characteristic makes it highly suitable for use as sensitive components, elastic supports, positioning devices and flexible connections in detection instruments or automatic devices.- ** Material Requirements ** : The manufacturing materials for spring sheets typically need to have high elastic limits, fatigue limits, impact toughness, and good heat treatment performance. Commonly used materials include carbon spring steel, alloy spring steel, stainless steel, copper alloy, etc.We can provide following OEM one-stop services:Product Description: Specification: Die Design & OpenWe use the most advanced die design software Auto CAD, Solidworks, UG (dwg), we open dies and tools ourselves.Our Capabilities:We use advanced technology, unmatched skill, professional equipments and rich experience technicians to fit our customers' requirements, like tooling manufacturing, stamping, deep drawing, welding, tube bending and surface coating serviceRange of Materials:Metal sheets include carbon steel, stainless steel, alloy steel, aluminum, copper, etc.Range of Material Thickness:It is 0.2-10mm for punching, stamping, forming, no thickness limit for welding.Processing Range:Progression die, Cutting, Stamping, Deep drawing, Bending, Punching, Threading, Welding, Tapping, Riveting, GrindingSurface Range:Plating(zinc, nickel, chrome), electrophoresis, painting, powder coating, electrostatic spraying, hot dip galvanized, dacromet, anodic oxidation, blacking, polishing, anti-rust oilPackaging & deliveryOur products are all packed in strong cartons and pallets/wooden cases to ensure zero damage.
