Leaf spring manufacturer
The leaf spring is one of the oldest variants of mechanical springs. Think for example of leaf springs under carriages and vehicles. It is a resilient product which can be manufactured in a wide variety of geometrical shapes. The most characteristic feature of the leaf springs or flat springs is that they are being produced out of resilient belt- and or strip material. The flat springs are, both as single pieces and as smaller series, laser cut or wire cut. The desired final shape is subsequently created by using folding machines and brake presses. Larger series are punched and folded by means of an automated stamping press. Afterwards, they get the required heat treatment and a possible surface treatment.
Applications
Flat springs or leaf springs are used in enormous varieties; they are therefore common in so many different markets. Think hereby of the automotive industry, mechanical engineering, aviation, household devices, precision industry etc. They are currently used in the most diverse applications. Think for instance of current flow and switches in the precision industry and electrical devices such as coffee machines and printer/photocopiers, as weapon clamp, as a spring for batteries, as clamping mechanisms at spots and ventilation systems, etc.
Materials
Frequently used types of materials for flat springs and leaf springs are stainless steel- spring steel 1.4310), C75 (1.1248) and copper alloys as Phosphor Bronze (2.1020 / CuSn6), Brass (2.0321 / CuZn37) and Beryliumcopper (2.1247 / BeCu). There are of course many more exotic materials applicable, mostly because of the resistance against high temperatures or aggressive environmental and ambient conditions.
Characteristics
Usually manufactured from strip- or sheet material, it possesses its own resilient features due to strong mechanical deformation of the starting material or due to a thermal curing process. Due to the wide range of production methods such as wire EDM, lasering, folding, stamping, corrugating; almost all shapes are possible. Material with a minimal thickness of 0,15 mm can be processed within our own factory. There are, for maximum dimensions, no limitations to mention. We can also produce leaf springs with a length of >1m. The ultimate resilience is being determined by the material thickness / the width ratio and the design. An important feature is the mostly compact overall dimension.
