Medical technology places the highest demands on reliability and process safety in the production process. Particular attention is paid to the assembly of medical products – not only because of the high regulatory requirements. It is not uncommon for bonding, encapsulation or sealing to take place under cleanroom conditions.
Our dosing systems and dosing components enable you to manufacture medical devices and parts with process reliability. Even with the most demanding requirements. After all, your customers’ lives depend on it!
Our purely volumetric dispensers allow continuous and pulsation-free dosing. And this is regardless of the viscosity of the adhesives, sealants, or potting compounds to be processed. The technology is particularly gentle and low-shear. This video clearly demonstrates the advantages of our pharmaceutical dispenser series.
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 dosing 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 used for bonding the components of catheters. RTV silicones or UV-curing adhesives are typically dispensed depending on whether the catheters are made of glass, plastic, or metal. We guarantee fast and consistent adhesive application with a repeatability of over 99%.
The potential of adhesive bonding technology in automated catheter production is evident when looking at developments in catheters. Catheters are used in various medical fields, such as intensive care medicine, urology, and cardiology.
Simply put, the manufacturing of a catheter begins with extruding tubes, which are then bonded to connectors. This adhesive connection ensures the tightness of the catheter. With our micro dispensing brand preeflow, even small amounts of adhesive are applied accurately. The volume remains consistent throughout the entire production cycle, and the delivery rate can be adjusted if needed for specific catheter components. The dosage remains precise even after the delivery rate is changed.
An optimal process combines extrusion, cutting, and bonding through automation.
Process-reliable filling of high-viscosity products in medical technology
Our dosing technology enables the process-safe filling of viscous, shear-sensitive, or abrasive products and so-called semi-solids. It is perfectly suited, for example, for dermal fillers such as hyaluronic acid or liposome-based depot drugs.
Filling is flexible but highly precise. The net dosing time can be less than one second per syringe – with a filling accuracy of >99%. Our special design allows a programmable suck-back, which ensures a defined thread break and prevents unintentional dripping or thread pulling.
