摘要:
A process for in-mold coating and a mold is disclosed. The process entails (i) obtaining a mold having at least two cavities, (ii) molding a thermoplastic substrate in a first cavity, (iii) introducing the substrate into a second cavity, and (iv) coating said substrate with lacquer, the coating being carried out under enhanced pressure.
摘要:
A process for the production of a molded article is disclosed. The process comprise a) placing a plastic film abutting the inside wall of a first half of a mold, said mold including a first and second halves, b) combining said second half with said first half in a manner creating a mold cavity, c) injecting resin into said cavity to produce an article to which surface adherently bonded is said plastic film, d) separating one of the halves from the other half, said article remaining with said other half, e) combining a supplemental half with said other half in a manner forming a gap between the inner wall of said supplemental half and the surface of said molded article, f) injecting lacquer into said gap, g) curing the lacquer to produce a lacquered molded article, and h) cooling and removing the lacquered molded article from the mold. The inventive process is particularly suitable for making vehicular mirrors.
摘要:
The invention relates to a method for producing an optical moulded body (2), in particular a lens element (2), comprising producing a pre-moulding (4) in a moulding tool by injection moulding of a first plastics material and producing at least one covering layer (6.1, 6.2) on the pre-moulding (4) by injection moulding of a second plastics material, wherein the temperature of the moulding tool for producing the pre-moulding (4) is from 30% to 60% lower than the temperature of the moulding tool for producing the at least one covering layer (6.1, 6.2).

The safety bumper includes: (a) a bumper basic body (4) having a forward surface; (b) a bumper bar (5); (c) a mounting member (11); (d) a cross-bar (10) of the vehicle, (e) at least one of a deployable energy-absorbing element (9; 32, 33, 39, 41; 52, 60) positioned above the mounting member (11) and a deployable energy-absorbing element (17, 20; 38, 46; 64) positioned below mounting member (11); and (f) an impact sensor (6) located in bumper bar (5). The bumper bar (5) is connected to bumper basic body (4) and extends through to the forward surface of bumper basic body (4), bumper bar (5) is also connected to mounting member (11), and mounting member (11) is located behind bumper basic body (4) and bumper bar (5). The mounting member (11) is connected to cross-bar (10), which is located behind mounting member (11). The deployable energy-absorbing elements are controlled by impact sensor (6), and upon actuation thereby are deployed and form (either singly or together) a substantially continuous contour and a substantially common front together with the forward surface of bumper basic body (4).
摘要:
Multi-layer composites comprising: (a) a first scratch-resistant coating layer comprising a first coating (primer); (b) a thermoplastic layer; and (c) a second scratch-resistant coating layer comprising a second coating (primer); wherein the first scratch-resistant coating layer and the second scratch-resistant coating layer are disposed on opposing sides of the thermoplastic layer; wherein the first coating and the second coating are not the same; and wherein the first scratch-resistant coating layer and the second scratch-resistant coating layer are selected such that a multi-layer composite having the first scratch-resistant layer disposed on both sides of the thermoplastic layer has a lower critical impact speed for tough/brittle transition at −30° C. according to DIN EN ISO 6603-1 than a multi-layer composite having the second scratch-resistant layer disposed on both sides of the thermoplastic layer; processes for producing the same; and uses therefor.
