Springs and pressings for medical technology. Certified production under highest cleanliness requirements.

Meet us at MD&M South in Charlotte, NC and see the leading design and manufacturing technologies up close.

Medical technology is in our DNA

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

We have am expansive network of production plants around the world with exceptional expertise and equipment dedicated to the medical sector.

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

Our medical technological high-quality standards are achieved through state-of-the-art production facilities and production technology, a large 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 springspower springsconstant force springsdeep drawn parts as well as stampings and bending parts.

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 and clean manufacturing solutions in spring technology for economical large-scale production with standard or special packaging.

In the production of our springs, we use state-of-the-art camera technology to ensure the manufacturing process and compliance 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.

Blood Lancet Devices

Compression springs, stampings and bending parts are commonly an integral component part in blood lancet testing units. These components deliver critically precise accuracy with certified technical cleaniness and are used to gain safe access to the blood. Our controlled ‘clean-room’ production environment guarantees the function and cleanliness of our springs, stampings and bending component parts. Consistent quality management is achieved through specifically designed washing and packaging concepts. Our medical manufacturing capabilities feature a high degree of automation, enabling efficient series production tailored to your project requirements.

Continues Glucose Monitoring

For continuous glucose monitoring, a sensor is placed under the skin. The latest generation of Glucose Monitoring (CGM) devices use an attachment that is controlled by constant force springs or compression springs. Precisely calculated torques and pressure forces ensure that the sensor is attached safely and comfortably.

Sustainability is a priority at Lesjöfors. We continously monitor our environmental impact through data analysis of our on-site production plants and our local supply chains.

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. Right from the start of the project, we take into account the spring separation, cleanliness requirements and series 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 compression 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, pressings, stampings and bending 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 spring technology for diagnostic and laboratory equipment covers the entire product development process, from the manufacture of sample parts to series production.
