Our company


Unimed S.A. is a swiss company active in the biomedical engineering field. We produce on demand a large number of medical needles and instruments for the medical, pharmalogical and laboratory fields and have become experts contract manufacturer in the shaping of stainless steel tubes.

Our Origins

The company's origins date back to 1936, when Pierre-Jean Guisan, son of a medical doctor and nephew of the famous swiss General Guisan, founded the company P.-J Guisan S.A and started the manufacturing of hypodermic needles for medical doctors and dentists in Lausanne.

In 1943, Mr. Guisan wanted to acquire the know-how of the drawing process used to produce stainless steel tubes. In order to do so, he founded a company named Microtubes.

In 1944, a company named Wander, bought 50% of both P.-J. Guisan S.A. and Microtubes S.A.
In 1946, M.Künzli, who was in charge of the medical activities of Wander, conducted a MBO. He founded Intramed and bought back the shares of Wander. He rapidly developed a vast number of products based on the syringes and medical needles. Unfortunately, the sales did not follow.

In 1950, the company entered into liquidation and was entirely bought by a company named Socorex. Following this acquisition, Socorex oriented the production towards syringes and medical needles, which became worldwide renown.

In 1954, Socorex's management decided to sell the hypodermic needles and syringes activities through a MBO conducted by two executives; Mr. Hertig and Mr. Karl Schoenholzer. The newly associates changed the company name into Socorex Medical Instruments, while the activities and manufacturing facilities remained unchanged. At that time, 80% of the manufactured needles and syringes were exported.

Unimed's creation

In 1958, the associates separate. Mr. Hertig is taking over the syringe activity and changes the company name; Socorex Instruments Médicaux becomes Socorex-Isba. Mr. Schoenholzer creates Unimed S.A. and is taking over the medical needles activity.

Under his leadership, Unimed S.A. developed the catalogue of medical needles proposed to the healthcare professionals and reinforces its activities regarding surgical suture needles, which started in 1951 with Socorex, as well as veterinary needles that integrates and complements the catalogue. By that time, the needles made by Unimed are sold in more than 70 countries.

In 1981, the son of Karl Schoenholzer, Mr. Patrick Schoenholzer joins the company. In the late 1980s, the fears regarding AIDS virus will lead to a rapid decline of the sales of reusable medical products. The activity of the company has to be reconsidered.

The whole range of the products produced until that time are considered as standard products from the field. It is decided to start a new activity by using the company's know-how in the field of stainless steel tube working and shaping. This new activity has major impacts for Unimed, that not only is a manufacturer, but also becomes a contract manufacturer for new clients in the fields of medical device, pharmaceutical or laboratories.

Today, Unimed possesses more than 1'500 active customers, spread across more than 70 countries. The customized products have become the main activity of the company and Unimed a strategic partner to answer technical, logistical and economical imperatives of each product manufactured for a world-renown clientele.
