A thermostatic bimetal consists of two or more layers of different alloys firmly bonded together, having different coefficient of thermal expansion result i.e. high expansion and low expansion. One layer consists of an alloy having a high coefficient of expansion while the other layer is one with a lower coefficient of expansion

A thermostatic bimetal consists of two or more layers of different alloys firmly bonded together, having different coefficient of thermal expansion result i.e. high expansion and low expansion. One layer consists of an alloy having a high coefficient of expansion while the other layer is one with a lower coefficient of expansion.   Thermostatic Bimetals have a wide array of applications but these can be classified under the following broad headings: Temperature indication. Control of any parameter against temperature. Compensation (usually for ambient temperature). Thermo-mechanical applications where heat is converted into mechanical energy.   The shapes most commonly used are: Cantilever strip Simple Beams Spiral and helix coils U-Shapes Discs Snap elements

shivalik manufactures and supplies various types of bimetallic helical and spiral coils. The configuration of the component varies on the basis of the end application. These configurations are precision manufactured to retain a uniform pitch and provide large movements for small temperature changes in a relatively small space. main applications: thermometers (spiral / helical)    maximum demand meters steam traps fan clutches ventilators dampers ambient temperature compensators. heat actuators

the snap acting thermostat metal disc is becoming increasing popular as a cost effective protection of small motors and appliances.   a disc of thermostat metal is pretensioned by dishing or doming. With a rise in temperature, the thermal stresses produced due to the bimetal action reach a point where they equal the pretensioning stresses. At this point the disc snaps to the opposite concave. Upon cooling the reverse action takes place but at a lower temperature. the upper and lower snapping temperatures depend upon the disc geometry. No exact mathematical formulas are possible to determine these temperatures but certain guidelines will help to establish the size and geometry of trial discs.

shivalik precision shunt resistors are characterized by low temperature co-efficient, high stability of electrical resistance, low watt loss, and good heat dissipation. Furthermore, since mounting generally involves contact with copper, the copper welded to each side facilitates the mounting without the problems of thermo ef and galvanic action.   electron beam welded shunt manufactured by us (using copper & resistance alloy strips) forms an integral part of "battery management system" (bms) or "intelligent battery sensor" (ibs) for vehicles as well as "electronic energy meter.” we have an integrated manufacturing capability from designing stage to bulk supplies.

To reduce the cost of labour and assembly Shivalik offers pre-soldered strip. The solder strip thickness and location can be varied as per customer's requirements. The base metals could be any steels, coppers and brasses. Such strips would eliminate the need for solder preforms or paste, besides enabling simple automation.

shivalik has in house stamping facility consisting of 10t, 20t, 40t, 50t stamping process that enable us to produce customize precision parts and components. we have our own sophisticated tool room consisting of the following machines cnc wire edm, edm drill, rotary grinder, milling machine, surface grinder, drill machine and lathe machine.

Electronics (Shunt Resistors) Shivalik Bimetal Controls Ltd. can design and supply customized shunt-resistors to suit customer's specific requirement. Electron Beam Welded Shunt manufactured by us (using Copper& Resistance Alloy Strips) forms an integral part of "Electronic Energy Meter." We have an integrated manufacturing capability from designing stage to bulk supplies. Shunt Resistors are used in: Inverters and UPS Power Modules AC/DC Converters Radio and TV Transmitters Frequency Converters

Our electron beam welding machines allow material to be selectively annealed at any location across the width. These soft zones will allow sharp bends in otherwise hard rolled materials. Shivalik can edge weld various combinations of alloys using the latest Electron Beam Welding Technology. Presently Shivalik has three Electron Beam Welding lines at its Solan facility

we can supply bimetal strips in thickness ranging from 0.1mm to 2.0mm and width ranging from 1mm to 72mm. Thickness and width outside this range can be supplied by special arrangement.
