The present invention relates to an enhanced method for the manufacture of a plastic component (135), in particular a cushioning element for sports apparel, the method comprising: opening a mold (100) by a predetermined amount into a loading position, wherein the mold comprises at least two mold parts (110, 112) and wherein the amount by which the mold is opened influences an available loading volume of the mold, loading a material comprising expanded particles (130) into the loading volume, closing the mold into a closed position, wherein during closing of the mold the mold parts are moved together over different distances (140) in different areas of the mold, compressing the expanded particles by closing the mold and fusing at least the surfaces of the expanded particles to mold the plastic component.

An ignition coil includes a not-illustrated coil, a plate assembly, and a case assembly. The plate assembly and the case assembly are combined with each other by laser welding at a recess and a rib (projection) which are respective abutting portions, thereby forming storage spaces for storing the coil.

Preform assembly for blow moulding a container, comprising at least a first and a second perform, wherein the first perform is positioned inside the second perform before blow moulding the performs into the container, wherein each perform has a body forming portion having a wall thickness of less than about 8 millimetres, preferably less than about 6 mm.

A method for the production of an elastic laminate, with the following steps in a production line: coextrudeing a first web of elastic film with at least three layers, with at least two different polymer materials, to feed contemporaneously said coextruded first elastic film web and two second nonwoven webs to a thermal, binding calender, wherein the first elastic film web is arranged between said two second nonwoven webs when entering the calender; wherein said first elastic film web, during the movement from the coextrusion step to the thermal binding step, passes from a melted state, to a solidified and cold state when entering the calender, to join, through spot welding in said calender, said second nonwoven webs with respective opposite outer layers of said first elastic film web, thus producing an intermediate web, to stretch mechanically said intermediate web according to a direction transverse to the same web.

The present invention relates to high-voltage components, especially for electromobility, containing polymer compositions based on at least one polyester and at least one sulfide containing cerium, and to the use thereof for production of polyester-based high-voltage components or for marking of polyester-based products as high-voltage components by laser.

To provide resin composition, a pellet and a powder for use in new powder additive manufacturing, as well as a shaped article using the same, and a method for manufacturing such shaped article. The resin composition comprises a polybutylene terephthalate that contains a terephthalic acid-derived structural unit and a 1,4-butanediol-derived structural unit, for use in powder additive manufacturing, the resin composition having a value (α), defined by mathematical formula [1] below, of 40 or smaller:

α=|(MVR.sub.1−MVR.sub.0)/MVR.sub.0|×100  [1] where, MVR.sub.0 is melt volume flow rate (in cm.sup.3/10 min), and MVR.sub.1 is melt volume flow rate (in cm.sup.3/10 min).

Embodiments herein are directed to an assembly that includes a circuit board, a plurality of terminal pins, a first material layer, a second material layer, and a third material layer. The plurality of terminal pins extend from the circuit board. The first material layer encases a portion of the circuit board. The second material layer encapsulates a portion of the plurality of terminal pins and encases the first material layer. The second material layer defines a connector interface. A material of the second material layer is different from a material of the first material layer. The third material layer encases the first material layer and at least a portion of the second material layer. The third material layer defines a housing that is formed from a material different then the material of the first material layer and different from the material of the second material.
