TEVEMA Product Introduction

The Netherlands' Tevema offers a wide variety of technical springs. TEVEMA specializes in customizing technical springs in large volumes or as single units. TEVEMA's standard spring catalog comprises 11 major categories, including the following products:

1). Tevema Compression Springs: Tevema compression springs are helical springs that withstand axial compressive forces. Springs are generally classified into constant-pitch and variable-pitch types. Compression spring shapes include cylindrical, conical, convex, concave, and a few non-circular forms. There is a certain gap between the coils of a compression spring; when subjected to external loads, the spring contracts and deforms, storing deformation energy. Variable-pitch springs are becoming increasingly common, moving beyond just constant-pitch designs, as they can perform differently under various conditions.

2). Tevema Extension Springs: Tevema extension springs are helical springs that withstand axial tensile forces and are generally manufactured from round cross-section materials. When not under load, the coils of an extension spring are typically tightly closed with no gap. They operate using the restoring force (tension) after extension, used to control component movement, store energy, measure force magnitude, etc., and are widely used in machinery and instruments. Hook forms include side-hook, long-hook, British-hook, German-hook, semi-circular hook, and duck-bill hook extension springs. Materials include stainless steel, music wire, high-carbon steel, phosphor bronze, beryllium copper, and oil-tempered alloy spring steel.

3). Tevema Die Springs: Tevema die springs are widely used in stamping dies, metal die-casting molds, plastic molds, other precision mechanical equipment with elastic movements, automotive applications, and more. Die spring material is generally selected from chromium alloy steel. Chromium alloy spring steel features high-temperature resistance, high rigidity, and long service life.

4). Tevema Torsion Springs: Tevema torsion springs leverage the principle of levers, twisting or rotating elastic materials with softness and high toughness to generate significant mechanical energy. These springs withstand torsional deformation, with their working parts consisting of coils that are either tightly wound or separately wound. The end structures of torsion springs are processed into various shaped torque arms, ranging from single to double torsion, and even various torque bar deformations, formed according to design requirements. Torsion springs are commonly used in balancing mechanisms in machinery and are widely applied in industrial production sectors such as automotive, machine tools, and electrical appliances.

5). Tevema Disc Springs: Tevema disc springs, also known as Belleville spring washers, were invented by the Frenchman Belleville. They are cone-shaped discs that can be used individually or in series/parallel combinations. They withstand static or dynamic axial loads at the upper inner edge and lower outer edge, deforming upon compression until flattened, storing energy as live loads. When necessary, they automatically convert into additional compressive loads required for sealing, reducing the continuous tightening requirements for gaskets and packing.

6). Tevema Constant Force Springs: Tevema constant force springs are a special type of extension spring suitable for applications with large extension amounts and non-increasing loads. Constant force springs consist of spiral metal strips, with the inner side of each strip curved so that each coil wraps tightly around the inner coil. When the metal strip is extended (twisted), internal stress resists the load force, similar to ordinary extension springs, but with a coefficient close to constant (zero).

7). Tevema Wave Spring Washers: Tevema spring washers are widely used in load-bearing and non-load-bearing structures of general mechanical products, characterized by low cost and easy installation, making them suitable for frequently assembled and disassembled parts. In the screw industry, spring washers are often called elastic washers. Materials include stainless steel and carbon steel (iron). Commonly used spring washer specifications include M3, M4, M5, M6, M8, M10.M12, M14, M16. These specifications are relatively common.

8). Tevema Nitrogen Gas Springs: Tevema mold-specific nitrogen gas springs (abbreviated as punch die nitrogen springs, nitrogen springs, nitrogen cylinders, or nitrogen tanks) are a new type of elastic component using high-pressure nitrogen as the working medium. They feature small size, high elasticity, long stroke, smooth operation, precise manufacturing, long service life (one million cycles), a flat elasticity curve, and no need for pre-tightening. They perform tasks difficult for conventional elastic components like metal springs, rubber, and air cushions, simplifying mold design and manufacturing, facilitating mold installation and adjustment, extending mold service life, and ensuring stable product quality. They can also be designed as a nitrogen spring system, participating as part of the mold, easily achieving constant pressure and delayed action within the system, representing a new generation of ideal elastic components with flexible performance.

9). Tevema Air Springs: Tevema air springs are non-metallic springs that achieve elastic effects by adding pressurized air into a flexible sealed container, utilizing the compressibility of air. They can be roughly divided into bladder-type and diaphragm-type. Air springs have excellent elastic characteristics; when used in high-end vehicle suspension systems, they significantly improve vehicle ride smoothness and thus greatly enhance driving comfort. Therefore, air springs are widely used in automobiles and railway locomotives. Additionally, due to their many advantages over ordinary steel springs, they are also applied in some mechanical equipment and precision instruments.

10). Tevema Ring Springs: Tevema ring springs consist of extension springs and connecting springs. The pitch and winding direction of the extension and connecting springs are the same. A specialized fixture clamps one end of the extension spring and screws it into the connecting spring. The other end of the extension spring is then rotated and fitted into the other end of the connecting spring. Rotational force connects the connecting spring inside the extension spring, forming a ring spring. This utility model ring spring does not affect the shape and elasticity of the connection point and is securely applied in various situations requiring ring springs.

11). Tevema Automotive Suspension Springs: Tevema automotive suspension springs are elastic elements in vehicle suspensions, providing an elastic connection between the axle and the frame or body, bearing and transmitting vertical loads, and mitigating and suppressing impacts caused by uneven road surfaces.

TEVEMA spring is a mechanical component that operates using elasticity. Components made of elastic material deform under external force and return to their original shape after the force is removed. They are generally made of spring steel. Spring types are complex and diverse; classified by shape, they mainly include TEVEMA helical springs, TEVEMA spiral springs, TEVEMA leaf springs, and TEVEMA special-shaped springs. TEVEMA can also produce large and small batches of TEVEMA compression springs, TEVEMA extension springs, TEVEMA torsion and leaf springs, TEVEMA spring wire, TEVEMA clock springs, TEVEMA precision springs, TEVEMA medical and suspension springs, etc., according to customer specifications.
