Embodiment Construction

[0033] figure 1 A cross-sectional view showing a first step S1 of the method for manufacturing a composite component 1 (see image 3 ), wherein only the associated components are partially shown.

[0034] In step S1 , the molded body 2 is formed from plastic, for example polycarbonate here, advantageously by injection molding with the aid of a first (“casting”) tool as casting mold. The mold is very simple, since the molded body 2 can be a simple imitation of the first tool W1.

[0035] The molded body 2 produced in this way has at least one depression 3 , which has, for example, a rectangular cross-sectional shape. The depression 3 is, for example, elongated in its longitudinal direction (perpendicular to the plane of the drawing) and can thus be referred to or regarded as a groove or elongated groove. Depression 3 in figure 1 neutralize figure 2 is shown with a port opening 4a pointing downwards and a bottom or base 4b above it.

[0036] The depression 3 transitions...

Abstract

The invention relates to a method (S1-S3) for producing a composite component (1) from a plastic material and an electrically conductive filler material. The method has at least the following steps: molding a molded body (2) from the plastic material, said molded body (2) having at least one recess (3), which is arranged adjacently to at least one projection (6) (S1); pressing the at least one projection (6) such that plastic material (7) of the molded body (2) is thereby displaced into an opening-side region of the adjacent recess (3) (S2); and introducing flowable filler material (9) into atleast one recess (3) and solidifying the filler material (9) (S3). A composite component (1) made of plastic material (2) and electrically conductive filler material (9) is produced according to themethod (S1-S3). The invention can be used in particular on a lighting device, which comprises at least one plastic / metal composite component (1) in particular.

Description

technical field [0001] The invention relates to a method for producing a composite component from a plastic material and an electrically conductive filler material, wherein the method has at least the following steps: forming a shaped body from the plastic material, the shaped body having at least one depression; and A flowable filling material is introduced into the at least one depression and the filling material is cured. The invention also relates to a composite component made of plastic and an electrically conductive filler material, which is produced according to the method. The invention can be used in particular for luminaires, which in particular have at least one plastic-metal composite component. Background technique [0002] Combining plastic injection molding and metal die-casting into a multi-material process is known from the information brochure "Integrated Metal-Plastic Injection Molding" of the Institute of Plastics Processing for Industry and Handicrafts ...
