Marsh Alliance can assist you in design, prototyping and testing of complex springs or offer advice on the approach to manufacture your component to ensure a long and reliable lifespan. Our unique spring product features are:
- Spring wire diameters available from 0.25mm to 16mm.
- Material selection to suit your application needs: hard-drawn, galvanised, 304 and 316 grade stainless-steel, and oil-tempered materials in stock or sourced globally.
- Full range of ends including all squared, open, closed, ground, pigtail ends.
- Marsh specialty coatings division offers a range of protective finishes including painted, zinc-plated, magni-coated and other anti-corrosive coatings.
- Cold coiled production method with stress relieving and strengthening process undertaken in-house, under controlled environment to deliver consistent results.
- Large and small production runs welcome depending on your needs.
Compression springs resist applied compression forces by utilising the energy that they store within. Commonly made from round wire, they are normally cylindrical in shape.
A compression spring may be coiled ‘left or right hand’, and several end options can apply. The most commonly used are ‘closed (square) only’ or ‘closed & ground’.
Marsh Springs produces a wide range of compression springs. We have automatic high-speed coilers for effective large volume production, or we can make up ‘1 or 2’ specific springs for any urgent requirements.
An extension spring resists a ‘pulling force’ exerted against it through energy stored. Normally made from round wire, the coils are ‘close-wound’, with some ‘initial tension’ included.
Many types of ‘hook’ formations are used to secure the spring in its application including full hooks, extended hooks, swivel hooks, and half hooks.
Marsh Springs manufacture a full range of extension springs, from small hearing aid and lock springs to large agricultural equipment springs.
The company also has developed in-house a range of automated equipment to economically produce high volume runs (eg: trampoline springs).
Torsion springs react to applied rotational force, either providing ‘torque’, or using stored rotational energy when the spring is set. The rotation force used allows the spring to decrease in diameter and increase in body length.
Marsh Springs has banks of machinery, including the latest CNC equipment, for torsion spring manufacture. We supply torsion springs for garage doors, window furnishings, agricultural equipment, and locks and latches to name a few.
