Combination Products

A combination product is the combination of a physical part and a drug which can be implanted or worn on the body for long-term treatments. Combination products offer several advantages when compared with drug delivery via oral, injection, and infusion methods:

  • Controlled release of the Active Pharmaceutical Ingredients (API): the controlled release as opposed to the bolus-type delivery facilitates consistent API concentrations within an optimal therapeutic range

  • Targeted delivery of the API: this strength of drug-eluting devices, particularly implanted devices, permits higher therapeutic dosages to be delivered while minimizing adverse side effects

  • Improved Patient Compliance: combination products improve patient compliance and most healthcare practitioners agree that within an aging population, compliance becomes less certain and therefore more important

  • Prevention of infection: an API added to a device can improve the device function and help to prevent local, as well as systemic infection

Product category: Extrusion

Custom Extrusion

Trelleborg Sealing Solutions has a long-standing history of producing extruded silicone hose and tube for the medical, pharmaceutical and biotech industries.

Trelleborg can vary inside diameter, outside diameter or wall thickness to exact specifications, as well as layer cross-sections from different materials to create products with unique features. In addition, we can manufacture very small extrusions, under 0.02 inch / 5 mm in diameter.

Our processes can create a myriad of designs including thin walled, thick walled, ribbed, perforated or split hosing and tubing. In addition, we can engineer any formed extrusion profile, including bends, coils or pigtails in single or multiple planes.

The vast majority of Trelleborg’s extrusions are custom fabricated to meet each customer’s unique requirements. The process typically begins in the tool room with the precision manufacture of a die and mandrel. Post-processing extrusion capabilities include services such as post curing, cutting, spooling, printing and drilling.

LSR & Rubber Molded Parts

Liquid Silicone Rubber (LSR) molded parts offer a virtually unlimited range of design. These are produced as a single part and can be manufactured in high volumes.

Advantages of LSR molded parts:

Limitless design – Enables production of part geometries and technical solutions not possible otherwise

Consistent – Provides the highest consistency in product dimension, precision and overall quality due to lean manufacturing processes

Pure – Silicone is one of the most extensively tested materials with a long history of safe use

Precise – Flashless, wasteless tool design concepts for parts from 0.002 grams to several hundred grams in weight

Reliable – Using latest technology in machinery, tooling and automation

Quality – ‘0’ Defect Quality Level through in-process controls

Fast – Enables highest volume production as a result of short cycle times; from several thousand to millions

Clean – Utilizing state-of-the-art processing techniques and production in Class 7 and 8 cleanrooms

Cost-effective – Offers lowest Total Cost of Ownership (TCO) for the customer

Trelleborg´s LSR components are the result of your and our designers’ imagination plus the quest for innovative solutions of our toolmakers and process engineers. LSR experts partner with customers using a holistic approach based on customers’ specifications and requirements.

Product category: Tubings and tubing equipment, Implants (passive)


Geometric transitioning allows for silicone tubing to change cross section during the extrusion process to eliminate molding and secondary bonding steps. This process reduces total cost of ownership for device manufacturer while improving part quality, device function and hygienic design. With GeoTransTM technology, assembled joints that may be weak, create additional failure modes or internal misalignments, where fluids can become turbulent or stagnate, can be eliminated.  

HCR silicone’s unique green strength, the strength of rubber in its unvulcanized state, allows for highly complex geometries in continuous extrusion processes. In the GeoTransTM process, tool components can be moved during extrusion to change cross sections substantially. This opens up new design possibilities in a wide range of medical devices, including wound drains, spinal and hemodialysis catheters.

A major advantage to the device manufacturer is that overall processing time and costs can be lowered. Although running a simple extrusion is faster than running a geometric transition extrusion, overall manufacturing, assembly, and quality testing time can be significantly reduced with the GeoTransTM process. For instance, the production volume of many long-term implants does not justify complex, automated assembly. However, a redesign to include a geometric transition can eliminate the need for manual assembly of a portion of the device.

Additionally, with less components and secondary processes the design validation step may be significantly shorter, and it can be easier to meet international standards and regulatory requirements for a single part, due to risk mitigation.

The technology is applied to custom applications with precision tolerances. Typical changes include:

  • Transition of a tube from a single to multiple lumens or splitting a multi-lumen tube into two or three single lumen tubes

  • One or more lumen stops and restarts within a multiple lumen tube, eliminating the need for secondary operations, such as backfilling a lumen used for filling a catheter balloon

  • A wound drain that comprises three separate pieces; an extruded tube, complex cross-section extrusion and molded hub, can be created as a single extrusion with two or more distinct geometric cross-sections and a smooth, integrated transition instead of a hub

  • Off-ration bump tubing, for applications requiring a variable outer diameter with either a constant or variable inner diameter, can be created with very short transitions down to fractions of an inch

  • Bifurcated tubing, which traditionally has four components: a two-lumen tube, two single-lumen tubes, and a molded hub, can be produced in one extrusion process
The GeoTransTM extrusion process has been used to manufacture products between 7 French and 24 French (on the catheter scale).

Multicomponent Technology

Increasing cleanliness and hygiene with 2C LSR technology

The simultaneous injection of LSR in combination with technical plastics, known as the 2C LSR technology, is one of Trelleborg´s outstanding capabilities. In what is commonly referred to as 2K, 2-shot, multi-component injection molding or co-injection, Trelleborg´s LSR experts employ highly advanced and sophisticated tool and process engineering to develop the most innovation solutions, combining two, three or more individual materials into one fully bonded, robust component.

The advantages of 2C LSR Technology are:

  • Offers designers much more latitude in design solutions
  • Can integrate multiple components into one fully-bonded solution
  • Single component is more robust than an assembly of individual parts
  • Provides lighter weight components
  • Risks and costs associated with secondary assembly can be avoided
  • Lowers cost by reducing the number of components in the customer’s supply chain
  • Increases cleanliness and hygiene by eliminating dead space and potential bacteria growth in the finished product
  • Enhanced processing options for more hygienic designs
Trelleborg Healthcare & Medical is at the forefront of tool, process and automation technology for 2C or two shot liquid injection molding. In a fully automated and closed loop system, either a combination of thermoplastic and liquid silicone or two dissimilar grades of liquid silicone are co-molded into a bonded component that offers a wealth of benefits in both assembly and function of the finished product.

A second process option for two component parts, suited for lower production runs and commonly applied by Trelleborg Healthcare & Medical is overmolding. Here, Liquid Silicone Rubber is injected over either a thermoplastic or metal component to create a fully bonded part.
