Product Description Customized all kinds of Springs and Metal Parts for Different Applications Compression Springs provide resistance to external load pressure. Compression springs are generally wire coiled with equal pitch and have a fixed wire diameter. Compression springs use multiple open coils to provide resistance to external load pressure (such as gravity pressing down on a wheel, or a body pressing down on a mattress), that is, they push back to resist external pressure. Round wire is the most common compression spring, but there are also compression springs made of square, rectangular and special shapes of wire. In addition, there are conical compression springs, or springs with a combination of conical and straight shapes. Depending on the application, compression springs can be used to resist pressure and/or store energy. Compression springs are used in everything from household appliances to motorized equipment, motors, etc., because it is the type of spring required. Compression springs are designed to be compressed by a load acting on them or their ends are compressed, and the wire of the compression spring is compressed to try to return the spring to its original shape, thereby pushing the load back.Main application areas: medical respiratory equipment, medical mobile equipment, hand tools, home care equipment, shock absorption, engine valve springs. Torsion springs use the principle of levers to twist or rotate soft, tough elastic materials to give them great mechanical energy. It is a spring that withstands torsion deformation, and its working part is also each circle is either tightly wrapped or separated. The end structure of the torsion spring is processed into various shapes of torsion arms, from single to double torsion, and even various torsion bar deformations, which can be formed according to the design. Torsion springs are often used in balancing mechanisms in machinery and are widely used in industrial production such as automobiles, machine tools, and electrical appliances.Extension springs are helical springs that bear axial tension. Extension springs are generally made of circular cross-section materials. When not under load, the coils of the extension spring are generally tight and there is no gap between them. When the two ends of the extension spring are pulled apart, the spring will try to pull them back together to absorb and store energy. Extension springs, also known as helical extension springs, are generally of equal pitch and circular cross-section. They can be used in many occasions, such as medical respiratory equipment, motion control, medical mobile equipment, hand tools, home care equipment, shock absorption, pump springs, mechanical and electronic protective hardware, fluid control valves, mechanical aerospace components, actuators, and switch equipment.Volute Spiral Springs is divided into contact vortex spring and non-contact vortex spring. For example, the tape measure in life is fixed by the mandrel and one end is pulled out for use. This kind of spring is called a spring spring or a constant force spring. The other is a non-contact vortex spring. This spring is often used in car seat recliners. We adjust the angle of the seat by twisting the car seat recliner.The volute spring, also known as the spring spring / clockword spring, is a variant of the torsion spring and also works through torque.Main application directions: car electric lift doors, seat back springs, winding box springs, yachts, lawn mowers, chainsaws and other engine startersMetal Stamping parts, most commonly used in hardware processing refers to the use of molds for steel/non-ferrous metals and other plates at room temperature, and the press provides the pressure required for processing to form them into a specified shape. It is widely used in various fields in our lives, including some electronic devices, auto parts, decorative materials, etc. The stamping parts we usually refer to are generally cold stamping parts.For example, if you want to turn a piece of iron plate into a fast food plate, you have to design a set of molds first. The working surface of the mold is the shape of the plate. Press the iron plate with the mold to become the plate you want. This is cold stamping, which is to directly use the mold to stamp the hardware material.Advantages of wire forming process:- Easy to operate: Friendly operation interface, flexible and convenient programming, only need to operate a switch to complete the whole complex bending process.- High efficiency: Adopt CNC three-axis numerical control system, AC servo motor drive, good consistency of processed products, fast speed.- Stable and reliable: The whole machine has perfect protection function, computer fault diagnosis function, and all high-quality components are used. - Strong adaptability: It can use high and low molds, and has a core pulling device. It has great advantages in bending complex pipes. It can store 9999 programs, which can be called and processed at any time, and has a computer interface.- Cost saving: Wire forming can avoid mold opening time and mold opening costs, saving customers' costsProduct DescriptionCNC Parts, CNC lathes and turning centers are high-precision and high-efficiency automated machining lathes. Equipped with multi-station turrets or power turrets, they have a wide range of machining process capabilities and can process straight cylinders, oblique cylinders, arcs and various threads, grooves, worms, etc. CNC lathe parts, with various compensation functions for linear interpolation, and have played a good economic effect in the mass production of complex parts.Baishun is equipped with more than a dozen CNC lathes, milling machines, drilling machines, cams, etc., and can customize various types of CNC control components.HOW to make customized products and its process:Customization process Customization based on drawings and samples 1.
