A surfacing material that is mold-releasable and electrically conductive. This surfacing material can be co-cured with a curable composite substrate and can be in contact with a mold surface such that when the cured composite part is removed from the mold, the surfacing material is releasable from the mold with ease. The mold-releasable surfacing material can effectively eliminate the need for mold release agents and mold surface preparation.

A mold cavity which is a mold die includes a die body and a plating layer provided on the surface of a mold surface. In this case, the mold surface has a leather-grain transfer surface for forming a grain pattern. The leather-grain transfer surface includes a first uneven-shape part and a second uneven-shape part formed at the surface of the first uneven-shape part and smaller in an uneven-shape width than the first uneven-shape part. The uneven-shape width falls within a range of 10 μm or more and less than 500 μm. The plating layer is an electroless-plating layer. A thickness of at least part of the plating layer falls within a range of 0.1 μm or more and less than 10 μm.

A mold for manufacturing a body made of a porous material derived from precursors of the porous material in a sol-gel process carried out within the mold can have a lower part defining an interior volume for receiving the precursors of the porous material, wherein the interior volume defines the shape of the body to be manufactured, and at least a first opening through which the body is removable from the lower part. Surfaces of the lower part facing the interior volume are at least partially provided with a coating made of a material that is electrically dissipative and non-sticky to a gel formed from the precursors of the porous material and/or the body.

Apparatus (1) for forming plastic preforms (10) into plastic containers (20). In a closed state of a blow mould (14), a contact area is formed between side parts (14a, 14b), in which the two side parts (14a, 14b) rest against each other, the side parts (14a, 14b) form a mould separation seam (5) in the contact area. In accordance with the invention, at least one section of at least one side part (14a, 14b) has a coating and/or an additional element (60) in a region of the mould separation seam (5), so that a heat transfer between the plastic preform (10) and the inner wall (52, 54) in the contact area can be delayed at least in places at these at least one section.

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.
