How does the shrink lamination systems work?

Shrink lamination systems are specialized machine used in the manufacture of medical catheters to cover and seal the outer material of the catheter. It works based on hot air technology and the following are the basic steps and concepts of how it works:

1. Material Preparation:
Before starting the laminating process, it is first necessary to prepare the substrate of the catheter as well as the thermoplastic material to be used for covering.

2. Hot Air Generation:
Shrink lamination systems have a built-in hot air generator which produces a precisely controlled stream of hot air. The temperature of this hot air stream can be adjusted to accommodate different laminating materials and catheter substrates.

3. Shrink lamination process:
Heating: Hot air is blown and applied directly to the laminating material to rapidly warm it to a soft or semi-molten state. This temperature must be precisely controlled to ensure that the material can be molded without being burned or damaged.

Laminating: The soft thermoplastic material is pressed against the surface of the catheter substrate. In some cases, the use of a mold may also be necessary to help form the specific shape of the overlay.

Cooling: The material on the overlay needs to be cooled to cure the shape after it has been tightened against the conduit substrate. CM80 shrink lamination system has air cooling system to help speed up this process.

4. Quality Control:
Once the overlay is complete, Operator will check the consistency and integrity of the overlay to ensure that there are no air bubbles, wrinkles, or other defects.

CatheterMelt CM80 Shrink lamination systems highly accurate temperature control and hot air flow adjustment features ensure a fine and repeatable laminating process. Therefore, It accommodates a wide range of different medical grade materials and complex catheter designs.
