Bonding, Potting, Sealing: With maximum reliability and process security

Medical technology places stringent requirements on the production process in terms of reliability and process security. Special attention is paid to the assembly of medical devices, not only due to the high regulatory requirements. These processes often take place under clean room conditions.

Our dosing systems and dosing components enable you to manufacture medical devices and parts with a high degree of process security under even the most stringent requirements. At the end of the day, your customers’ lives depend on it!

Our purely volumetric dispensers enable continuous and pulsation-free dosing. And this regardless of viscosities of the adhesives, sealants or potting compounds that must be handled. The technology is particularly gentle and low shear force. In the video you can see the advantages of our pharma dispenser series in detail.

Application examples for medical technology

Bonding Pacemaker Shells


One application for our dosing pumps is bonding of pacemaker shells. Both with one-component and two-component adhesives.

We guarantee absolutely precise work in all applications: Because even with very fine dosing dots or lines with extremely small volumes of material, we achieve an exact mixing ratio. From the beginning to the end of the dispensing bead.

You benefit from an adhesive bond in many ways:

  • Low or non-existent thermal load on the joining materials.
  • Surface and microstructure of the components to be joined remain unchanged during bonding.
  • An adhesive bond can also have sealing properties.
  • Nearly all components can be bonded – from very small to very large.
  • An adhesive joint with UV adhesives allows repositioning of components during assembly.

At best, medical devices are manufactured fully automatically. Since manual handling is the biggest cost driver. You can read here how the gaps in partially automated processes can be closed.

Bonding Catheter Components


Our dispensers are also used to bond catheter components. Depending on whether the catheters are made of glass, plastic or metal, RTV silicones or UV-curing adhesives are generally dispensed here. We guarantee very fast application with reproducible adhesive application – with a repeatability of >99 %.

A look at the developments in catheters shows the potential of, for example, adhesive bonding technology as a component of automated production in the field of catheter manufacturing. There is hardly a medical field in which catheters are not used. Whether in intensive care medicine for ventilation, in urology as a bladder catheter or in cardiology as a heart catheter – the list could go on.

In simple terms, the manufacturing of a catheter always begins with the extrusion of the tubes, which in the next step must be bonded to the so-called connectors. This adhesive connection must simultaneously ensure the tightness of the catheter. With our micro dispensing brand preeflow, even the smallest quantities of adhesive are applied with pinpoint accuracy. The volume is demonstrably the same throughout the entire production cycle. The delivery rate can be optionally changed if required by a specific component of the catheter, such as balloon, cuffs or even connectors. Even after the delivery rate has been adjusted, the dosage is exact.

An optimal process combines extrusion, cutting and bonding via an automated process. As the error potential is highest during manual joining. We will be happy to advise you on the implementation of such a process – simply fill out our contact form.

Process safe filling of highly viscous products in dental industry and medical industry

Dental care

Our dosing technology enables the process safe filling of highly viscous products like for example dental ceramics, tooth whitening gels and polymers for dental products as well as medical products like hyaluronic acid. It is also suitable for abrasive materials like polishing pastes.

Process safe dosing with a deviation of ± 1 % in volumes (from 0.1 ml) are assured through absolute linearity between the rotor speed and the output quantity as well as by a controlled break of the thread (= no drip effect) through adjustable reverse flow after dosing.

Read here how you can save time and material with our semi- and fully automatic systems. For example, when filling composites.
