Coil spring is a helical spring that offers resistance to a compressive force applied axially. Most coil springs with material diameter less than 9mm are cold coiled. Almost all custom coil springs using over 14in bar stock are hot coiled. There is an overlapping area from 9mm to 14mm material size in which the custom coil springs may be either cold coiled or hot coiled. Custom hot –coiled helical springs are usually preset. They are wounded to a length greater than the finished length; heat treated, then compressed solid three or more times to bring them to the specified length. Presetting introduces beneficial residual stresses which allow the springs to support greater loads than would be otherwise possible. Service life is increased by shot peening, which is particularly effective when both the hardness and working stress are high. Rust leads to pitting and pitting to early failure, so some form of protective finish is recommended. The kind of coating required will depend on the environment which the springs are expected to encounter in storage and service. The transportation industry is the largest user of hot coil springs.   In ordering coil springs give the following information as completely as possible: Free length, maximum, minimum. Controlling diameter, outside diameter maximum. Inside diameter minimum. Pitch diameter. Works inside (dia.hole). Works over (Dia.Shaft). Number of coils. Wire size. Decimal size if possible. Material, Kind and Grade. Loads at deflected positions. Finish. Plain unless otherwise specified. Maximum solid length. Frequency of compression Heavy duty coil spring is one of the coil springs. Especially it is designed to carry more weight such as in cars and trucks. Whereas heavy duty coil springs normally thicker and shorter than stock springs. Moreover, the thickness may be same but there are fewer coils. It is called under the stronger springs

MINI Barrel Springs are a type of compression spring where the coils are reduced in diameter as they get closer to the ends of the spring. As in regular compression springs, loads can be changed by varying the material size, active coils and free length. The shape of the barrel can also affect the loads. MINI Barrel Springs tend to buckle less under load and may be designed to allow some coils to compress inside one another to give a lower solid height.To speed up the production process and lower costs for the buyer, automated equipment is used to produce most barrel springs. Barrel (convex) Springs are produced so that they have a higher tolerance to buckling under certain stresses. Unlike a typical compression spring, the barrel spring is convex in shape, which allows for a lower solid height under load.

With the latest technology and proficient manpower, MISPL excels in the manufacturing of Compression Springs, Constant and Variable Rate Springs, Leaf Springs, Conical Springs, Pigtailed Springs, Mini Block Springs, Hot Wound Springs, Piston Rods and Bright Bars.

MISPL manufactures custom compression springs to the exact requirements of our customers’ needs. Instead of going over what the technical definition of a compression spring is, we would like to share what we believe will help people the most when designing or buying compression springs. Compression springs are a type of wire spring used in everything from appliances to motorized equipment, motors and more because it is the required type of spring. Compression springs are compressed by load acting upon them or their ends are compressed, the design of the wire tries to return the spring back to the original shape thus pushing the load back. One can control the action of the compression spring by how it is designed. The diameter of the coil, the numbers of coils, the style of the ends even the length and diameter and shape of the wire can all make different compression springs. This is why it is so important to have all the right dimensions when ordering a spring so its performance will meet the needs of the application.

Conical Compression springs are often specified where the large end is meant to work in a bore and the small end is meant to work over a rod. They offer the advantage of a reduced solid height compared to straight compression springs, especially when capable of “telescoping.” Conical Springs are Cone shaped compression springs designed to provide a near constant spring rate and a solid height lower than a normal spring.
