Techsil launches PUR Form-in-Place-Foam-Gasketing service

UK-based industrial sealants and adhesives company Techsil has announced that it has launched a new PUR Form-in-Place-Foam-Gasketing (FIPFG) service.

Using a single-component liquid polyurethane foam sealing system and machine technology Techsil’s gasketing service is the economical and reliable solution for replacing labour intensive peel and stick gasket applications.

Taking measured quantities of material and compressed air the mixture is homogenised and through shear forces is converted to a uniform foam structure upon application to the component. The curing process takes place without any chemical reaction forming a fine, closed-cell structure. The automated system can vary the ratio of material to air and create a wide range of foam hardness depending on the customer’s specification.

Steve Green, technical sales manager, said: “Offering a contract gasketing service is a new venture for Techsil that has come about through customer need and dovetails nicely with our existing product portfolio. I can reveal that this service has particularly captured the interest of manufacturers in the lighting, electronics, automotive and packaging sectors.

“Techsil’s contract gasketing service uses sophisticated six axis robot dispensing systems that provide the perfect bespoke gasket every time. Short cycle times save time and money. If a manufacturer produces small volumes or has intermittent production, then subcontracting their FIPG system will be very cost effective.”

Dispensing of only one component ensures that even very small sealing gaskets can be produced accurately without any problems. However intricate the part, a perfectly engineered foam gasket can be applied; from micro-dispensing of gaskets to replace o-rings, to high volume applications of foam to doors of switch cabinets. Furthermore, the thixotropic properties of the foam ensure that very complicated tri-dimensional shapes and cross-sectional variations can be accommodated.
