Definitions
- the invention relates to a method for producing multi-component molded plastic parts from a first, thermoplastic component and a second component from a crosslinking elastomer.
- thermoplastic injection molded parts each consisting of a thermoplastic plastic
- the first component is a thermoplastic hard component
- the second component is a thermoplastic elastomer such as TPE.
- a plasma spraying device is inserted between the mold halves after opening the injection mold and the molded part made of the thermoplastic hard component is subjected to a plasma gas jet.
- the plasma spraying device is moved out of the open injection mold, the mold halves are rotated and in the next step, a thermoplastic elastomer is molded onto the pretreated molded part as a second component, while another mold part is molded from the other thermoplastic hard component is generated.
- thermoplastic hard component is molded in a first injection step and then a corona treatment of the thermoplastic hard component is carried out in the adhesion area.
- the soft component which also contains a cross-linking elastomer such as e.g. Silicone rubber can be molded.
- the object of the invention is to provide a method which, with an equally good connection of the thermoplastic hard component to the crosslinking elastomer, results in less stress on the hard component and is easier to control.
- thermoplastic hard component a thermoplastic hard component and a crosslinking elastomer is also possible if the hard component is replaced with a plasma gas stream the corona treatment, which is difficult to control.
- environmentally harmful adhesion promoters can be dispensed with entirely.
- thermoplastic hard component is usually injected into a cooled tool, while the cavity for the crosslinking elastomer has to be heated so that the crosslinking can take place.
- the thermoplastic hard components include: PC; PA, PBT, PP and others.
- LSR Liquid Silicon Rubber
- HNBR, NBR, ACM, EPDM, FPM and similar cross-linking elastomers are also used depending on the area of application.
- the lower mold half 1 of an injection molding tool is clamped on a turntable 17 and can form two different cavities with the upper mold half, not shown here.
- a preform 2 is produced from a thermoplastic hard component in a first cavity of the injection mold (on the right-hand side in FIGS. 1 and 2).
- a plasma nozzle 4 is moved over the pre-molded part 2 by means of a suitable handling device 18 and a plasma gas stream 5 is applied to the latter.
- the turntable 17 and thus the lower mold half 1 is then rotated and closed again. Now, in a second cycle in the second cavity (on the left in FIGS.
- a suitable plasma nozzle 4 has a stainless steel housing 6 with a nozzle head 7 and an insulation layer 8 on the inner wall of the housing 6.
- a gas line 9 opens into the cover of the plasma nozzle 4 and is connected to a gas supply station (not shown here).
- a pinhole 10 divides the inside of the housing 6 into a gas supply chamber 11 and a gas discharge chamber 12.
- a first electrode 13 is attached to the pinhole 10 and is connected via a line 14 to a high-voltage source, not shown here.
- the nozzle head 7 of the stainless steel housing 6 acts as a second electrode which is grounded.
- a plasma 15 is ignited between the electrode 13 and the nozzle head 7, which emerges from the nozzle and strikes the surface of the molded part 16 as a plasma gas stream 5. With this plasma gas flow, a uniform and comparatively gentle treatment of the preforms is possible.
- Rotary tool - lower mold half First component pre-molded part made of thermoplastic hard component
- Second component cross-linking elastomer
- Pinhole gas supply chamber Gas discharge chamber
- Electrode Electrical line Gas discharge section Molding surface Turntable handling device
