Multicomponent Injection Molding Of Thermoplastics And Liquid Silicone Rubber (LSR) – Either Cured By Heat Or UV Light
Abstract
For processing thermally curing liquid silicone rubber (LSR) as well as UV light curing LSR for multicompo-nent injection molding with thermoplastics in an compa-rable way a processing center was designed and set into operation.
For the production of the multicomponent specimens a modular tool was designed. In there a thermoplastic plate gets molded on the one side, then gets transferred auto-matically by a robot system and gets overmolded by the silicone on the other side. The complete silicone side of the tool is easily changeable from a heated cavity, which is more or less state of the art, to a transparent cavity, wherein the UV LSR gets cured by according LEDs.
In first studies tests have been carried out concerning the adhesion between several thermoplastic materials and different LSR types, cured by heat as well as by UV light. The adhesion has been tested according to VDI 2019.
The used injection molding technique makes an interme-diate treatment like surface activation of the thermoplastic plate possible before it gets overmolded. Therefore exem-plarily different surface treatments and their effects on the adhesion strength of the material composite were evaluat-ed.
