Thermal sealing for joining of polymer parts

Polymer parts can permanently be joined by using thermal sealing processes without the use of solvents.

Components remain dimensionally stable: With our various hot presses, the pressing force and duration, temperature and air pressure can accurately be adjustedfor an optimal sealing result.

Process development on finely adjustable hot presses

Starting from the selection of suitable  sealing films to custom-fit manufacturing of sealing tools and on through to joining the plastics on the hot press: We advise and support you in the evaluation and implementation for your product. For process development, multiple hot presses are available that enable high-precision parameter settings. Thus, exact and robust processes can be developed - in concordance with the requirements of your product.
From process development to mass production: After a successful trial, the developed processes can seamlessly be transferred and ramped-up on our pilot line.

Firmly connecting plastic parts: Our thermal sealing expertise

Hahn-Schickard has many years of experience in thermal sealing of polymer cartridges and components. In our application development, we evaluate how micro-thermoformed films, hot embossed parts or injection molded parts can be firmly bonded to each other. Particularly in the production of diagnostic products, the advantages of the process are manifest e.g. for packaging of fluidically leak-tight and functional lab-on-a-chip systems: Custom-made films allow reliable sealing without microchannel deformation and without thermally or chemically harming pre-stored reagents.
