Coil Springs

Compression Springs
The open-coil helical Compression springs are springs that offer resistance to a compressive force applied axially. They are used to resist applied compression forces or to store energy. Compression springs are most commonly used in engineering, tools, automotives, aerospace and consumer applications.
Wire Selection: Springs are made out of Round, Square or special-sections, with round being the most adaptable.
Dimensional Limits: Governed by the pitch allotted with regard to allowable solid height, outer and inner diameters.
Stress Level: Determined by the dimensional limits together with the load and deflection requirements. Our compression springs are stress-relieved to remove residual bending stresses produced by the coiling operation.
Tension Springs
Tension springs are stressed in shear but are “pulled” rather than “pushed”, in order to effect energy transfer. By this stress mode these springs take different end forms to achieve and effect the actuation of the energy stored. The forms of the ends is varied and available in all shapes to suit the end user application. However there are a number of standard or commonly used shapes.
Wire Size: 0.3mm to 10mm
Material: Round – Spring steel wires & stainless steel wires, and also Pb wires.
Ends: There is a large variety of end types that can be put on a tension spring including machine loops, extended loops, double loops, tapers, threaded inserts, hooks or eye lets at various positions, extended hooks.
Torsion Springs
Torsion or double torsion are helical springs used to apply torque or store rotational energy. A torsion spring exerts a force in a circular arc and the arms rotate about the central axis. The stress is in bending and not in torsion. It is customary to specify torque with deflection or with the arms at a definite position.
Special types of torsion springs include a double torsion spring having a space between the coils to minimize friction. Double torsion springs consist of one right-hand and one left-hand coil section connected together and working in parallels.

Part I. The Metallurgy of: “Alloy Selection for Elevated Temperature Application”

Introduction This is a complex subject in part due to the time dependant mechanical behaviour of metals under load at elevated temperature. At room temperature, we understand that a part is failing once it is past it’s yield point – plastic deformation is occurring. The part is completely destroyed once…

Part II. The Metallurgy of: “Alloy Selection for Elevated Temperature Application”

Malabou cast special alloys that allow for castings to be used at elevated temperature’s, in some cases in excess of 1000°C. These heat resistant casting alloys consist of predominantly of combinations of nickel, chromium and iron together with small percentages of other elements. Castings made of these high temperature alloys…
