COMPRESSION SPRINGS

These type of springs are typically manufactured from round wire and in a cylindrical shape. However, square or rectangular wire can also be utilised and spring can be shaped in barrel, conical, hourglass and other profiles

Spacing between coils can also be varied to provide different spring rates throughout the operating range of the spring. This type of spring represents an extremely flexible design approach to force resistance and energy storage.

In these type of springs, we have capacity to produce in automatic or CNC machines from wire diameter 0.15mm to 14.00mm and manually up to wire diameter 20.00mm. Most of the materials that are used in these types of spring are alloy steel wire, piano wires and spring wire. Depending on the nature of requirement of customer, specific material is used to get the required results and for long life of the spring.

All the machinery related with the processes of heat treatment, grinding, shot peening etc. are available in-house for smooth running of production.

EXTENSION SPRINGS

To fit the function of extension springs, a multitude of hook or loop is used. Close winding of the body is used to provide initial tension in the spring to help manipulate the load and rate.

The travel of the extension spring may be manipulated by the hook length to also give the optimum load preference. Applications for extension springs include automotive interior and exteriors, toys etc.

In these type of springs, we have capacity to produce complete spring on machine that can use maximum wire diameter up to 5.00mm. No hand work is required after processing of wire on those machines. Complete spring as per required criteria is produced with accuracy and of same size using CNC Spring Making Machine.

In these type of springs, we have capacity to produce complete spring on machine that can use maximum wire diameter up to 5.00mm. No hand work is required after processing of wire on those machines. Complete spring as per required criteria is produced with accuracy and of same size using CNC Spring Making Machine having sensors to control sizes of the spring.

PARTS:

TORSION SPRINGS

Torsion Springs, whose ends are rotated in an angular deflection, offer resistance to externally applied torque. The wire itself is subjected to bending stresses rather than torsional stresses, as might be expected from the name.

Springs of this type are usually close wound, reduce in coil diameter, increase in body length as they are deflected. Special types of torsion springs include double torsion springs and springs having a space between coils to minimise friction.

Most common materials used in these type of springs are round wire, square and rectangular wires. Automotive applications of these type of springs include windows regulators, seat recliners, door handles, pedals, mechanical assemblies, etc.

In these type of springs, we have capacity to produce complete spring on machine that can use maximum wire diameter up to 5.00mm. No hand work is required after processing of wire on those machines. Complete spring as per required criteria is produced with accuracy and of same size using CNC Spring Making Machine.

PARTS:

WIRE FORMS, RETAINING RINGS, CLIPS, SPRING STEEL PARTS

At this time, we are making different wire forms, clips, retaining rings and spring steel material parts for different customers. Different materials of standard quality are used to manufacture these parts as per the requirement of applications. Materials that we use include Spring Steel material SK5, SK7 etc.

These parts as per their applications are properly heat treated and tested to qualify for their fitment. These parts are manufactured on manual as well as on automatic forming machines.
