Spring formed components

Spring formed components

The fourslide process from Lee Spring delivers stamped and formed flat springs to custom designs and for extended runs of manufacturer standards. Fourslide manufactured parts find application throughout manufacturing across industries such as electronics, aerospace, automation, white goods, specialist vehicles, rail, building/construction – wherever a custom strip or wire fixing or fitting is required in high volume and to low cost. This includes flat springs, brackets, clips, flat terminals, or any stamped and formed metal components otherwise requiring custom tooling to produce intricate metal parts from flat strip material or from drawn or rolled wire.

The fourslide process can reduce part cost, accelerate product delivery and streamline quality assurance with an integrated stamping and forming operation. Fourslide production has low to moderate tooling costs and produces accurate repeatable parts quickly and reliably.

The most commonly used materials with fourslide manufacturing are low-carbon or high-carbon cold rolled steel, type 300 and 400 stainless spring steels, copper alloys including beryllium-copper, bronze alloys including phosphor bronze. The greatest advantage of the fourslide machine however is its ability to complete all of the actions required to produce a part from start to finish economically. It can handle certain parts that transfer or progressive dies cannot, since it can manipulate from four axes. Because this process requires less machinery, setups and handling, the cost of the finished part is reduced.

Rapid response is paramount in all industries, so when an engineer or technician reaches for an item and finds a gap on the rack, that’s when frustration and delays kick in. With that in mind Lee Spring have developed spring kits which meet a comprehensive range of needs for design, prototyping and development purposes.

The kits provide a selection of different sizes and are available for standard compression, extension and torsion springs, as well as instrument springs. They are housed in a heavy duty selection case, coded so that each type of spring can be quickly identified by using a reference chart inside the lid, or by colour coding where appropriate.

A comprehensive selection of compression springs is available in plated music wire or passivated stainless steel, likewise each extension kit comes in a robust case with each compartment containing three pairs of extension springs. 216 instrument springs in 108 different sizes are available at the flip of a lid with each pair of compression, extension and torsion springs in easily identifiable compartments. Instrument springs are available in music wire only.
