Technical springs, bent parts and stamped parts for
medical technology. Certified production under highest
cleanliness requirements.

MEDICAL

Lesjöfors manufactures and supplies the medical industry with technical springs, bent parts and stamped parts from wire or strip material for disposable medical products, medical equipment and hygiene-related products.

For this purpose, we have several production plants around the world with the expertise and equipment for your medical project. 

Regardless of the quantity and application, we offer innovative solutions for  manufacturing, cleanliness, packaging and automation.

We achieve our high quality standard in medical technology through state-of-the-art production facilities and production technology, a large vertical range of products, use of the latest laboratory technology and certified standards.

Injectors for
drug administration

Autoinjectors, drug delivery devices, or pen injectors utilize compression springs, torsion springs, constant force springs, power springs, roller springs as well as stamped parts and bent parts, depending on the design and application.

The use of technical springs ensures exact dosing of the drug as well as a high level of safety for the user. We offer automated manufacturing solutions for economical large-scale production, taking into account cleanliness requirements and standard or special packaging. In the production of our springs, we use the latest camera technology to ensure the manufacturing process is compliant with spring tolerances.

In addition to technical cleanliness, we are also familiar with the requirements for organic and biological cleanliness in the field of medical technology.

Syringes

Syringes for medical technology mainly use compression springs. Release and retraction mechanisms of safety syringes, or needle shields, are controlled by spring technology. Depending on the application and specification, we configure and calculate the optimum material grade and spring design.

Essentially, stainless steel materials in different material grades and surface finishes are used. At the beginning of a project we take into account all factors, including spring separation (tangling), cleanliness requirements and series production packaging as well as the further processing of the spring in the final assembly process.

Blood collection and
infusion technology

One of the newest and most common ways of venous blood collection and infusion is via winged cannulas (butterflys). To avoid unintentional transmission of infection caused by needle sticks, winged cannulas are increasingly being equipped with needle retraction systems, or needle shields.

The needle retraction is controlled by a spring. In the field of medical technology for blood collection, we work with the highest requirements in terms of technical and organic or biological cleanliness. We achieve this through special spatial conditions and automated spring production.

diagnostic and laboratory equipment

Like the variety of our springs, stampings and bent parts, the applications in the field of diagnostic and laboratory equipment in medical technology are almost unlimited. Examples for the use of our springs would be applications in the field of radiology (MRT), lancing devices, and blood glucose meters.

Our equipment in the field of medical technology is also ideally suited for medium and small production batches. Our expertise in the field of spring technology for diagnostic and laboratory equipment covers the entire product development process, from the manufacture of sample parts to series production.

inhalers and pump sprays

Depending on the design, compression springs, bent parts and stamped parts are used for inhalers and pump sprays in the medical field. The requirements for technical cleanliness, organic cleanliness and biological cleanliness are particularly high here.

We therefore manufacture these products under special cleanliness and hygiene conditions. We offer a complete cleanliness chain from the selection of suitable materials, manufacturing processes, packaging concepts to residual dirt analyses. We are a full-service provider for our product portfolio and handle all stages of the value chain.

medical equipment

Technical springs, bent parts, stamped parts and gas springs are an integral part of medical technology. They are used in a wide variety of applications in small, medium and large quantities.

Examples of the use of our products would be compression springs for hospital beds, power springs for climbing aids, constant force springs for x-ray equipment balancing, stamped parts for patient transport trolleys, constant force springs for automatic fall detection systems, wire bending parts for prostheses, bent parts for hearing protection, and many more.

medical hygiene products

Requirements in the field of hygiene are becoming increasingly important. We supply customers in medical technology, cosmetics and sterilization. Our technical springs play a major role in ensuring that the hygiene products are safe. In addition to the requirements for cleanliness, the precision and service life of our springs also play an important role. Applications for medical hygiene products include soap dispensers, disinfectant dispensers, paper towel dispensers, fragrance dispensers and various applications in cosmetics. With our locations in Europe, Asia and the USA, we meet the highest standards of quality and delivery performance.
