A method for making a molded composite includes the steps of providing a lower mold that has an upward depressed surface having first and second surface regions and an interconnecting region, placing a mold release film on the upward depressed surface to cover at least the first and second surface regions and the interconnecting region, placing a molding material on the mold release film such that the mold release film is disposed between the upward depressed surface and the molding material, and hot pressing the molding material by pressing a downward pressing region of an upper mold toward the upward depressed region of the lower mold so as to form the molding material into a molded composite.

The invention relates to a welding tool and to a method for pulse welding of plastic films for medical packs formed as bags. In general, the invention provides that the film material which is plastified during welding and thus free-flowing is specifically displaced into a deepened, edge-side inner region of the sealing surface by increasing the sealing surface area. The film material accumulated in the recess leads to an increase in the film thickness in the inner region (25i) of the weld seam (6, 7, 8). As a result, the mechanical stability of the medical pack formed as a bag can be improved.

Surface material of a mold molding surface and surface treatment method. A molding surface of material including metal and in which the molding surface reaches 50° C. or higher during molding is subjected to rapid thermal processing by injecting a substantially spherical shot with a hardness equal to or greater than the surface hardness of the mold and a size of #220 (JIS R6001-1973) or smaller at an injection pressure of 0.2 MPa or more and bombarding the surface with the shot, causing the temperature to rise locally and instantaneously at a bombarded portion to refine the surface structure of the surface and to form numerous smooth arc-shaped indentations on the entire surface of the surface. Then, powder including titanium having size of #100 or smaller is injected at an injection pressure of 0.2 MPa or more to form a coating of titanium oxide on the surface of the surface.
