Medical devices getting smaller by the day

Written by: Lee Spring Ltd | Published:

The latest technology means that devices are getting smaller every day. So the latest Spring technology has had to follow suit. Lee Spring responded by bringing its smallest Bantam ™ mini compression springs into the company's now 20,000 strong catalogue range.

Bantam™ mini compression springs are a unique line of miniature springs available in wire diameters of .0040", 0.0045", 0.0040" and 0.0055" with external diameters of 0.0025", 0.040" and 0.057". Available in a range of lengths from 0.005" to 0.0625". In order to maximise the performance of a diverse range of applications, notably for the Medical industry, Lee Spring chose 'Elgiloy' as the alloy most suitable for these springs.

Egiloy is a Nickel-Cobalt alloy known for its durability. It is 10% stronger than type 316 Stainless steel. It demonstrates a greater resistance to corrosive environments including lactic acid, ammonium chloride, citric acid, sodium chloride and sodium sulphate. This material performs well in temperatures up to 850°F and is non magnetic.

Bantam mini compression springs are used in many applications in diverse industries such as:

Medical Devices

Pharmaceutical delivery devices

Petro-chemical processes


Marine industry

Security and locking devices


Electronic and illuminations controls

Communication devices

Precision instruments
