It is a metallurgical process in which the springs are heated to the temperature of about 850 C so that the conversion to austenite takes place. These springs are then taken out of the furnace and are placed in the bath of water so that rapid cooling takes place.

The spring manufacturing process allows for flexibility and versatility of spring design and function, whether for advanced commercial or heavy industrial applications or for ordinary everyday products. Our Tool & Die Shop can handcraft prototypes to verify that your product design meets your requirements prior to fabricating the final tooling.

The invention provides a manufacturing process of a high-stress spring, which comprises the following steps: winding the spring raw material into a semi-finished spring by using spring coiling equipment, and checking and screening the free length of the semi-finished spring; tempering the screened qualified semi-finished spring for the first time; placing the semi-finished spring into an

We build springs following three basic steps: Coiling First, we feed the wire through a straightening process. The straighter the wire as it enters the coiler, the better the part it will produce.

Hot winding is a spring manufacturing technique used for thicker wire or bar stock. The spring material can be coiled into springs if the metal is heated to make it flexible. Standard industrial coiling machines can handle steel bars up to 3 inches in diameter, and custom springs have reportedly been made from bars as much as 6 inches thick.

as possible to the spring manufacturer in meeting these require- a process of manipulating the formulas for spring rate and torsional stress (see p. 8).

Compared to steel springs the optimized composite spring has strength that are much lower, the natural frequency is high and the spring weight is nearly 80% lower. D. Abdul Budan and T.S. Manjunatha has investigated the use of different composite material in helical coil spring of suspension system and other automotive applications.

Fakkir et al, in the present work emphasizes on the reduction in weight of suspension system by using composite material instead of customary leaf spring [5]. The process begins with selection of
