The present disclosure is directed to an apparatus for manufacturing a composite component. The apparatus includes a mold onto which the composite component is formed. The mold is disposed within a grid defined by a first axis and a second axis. The apparatus further includes a first frame assembly disposed above the mold, and a plurality of machine heads coupled to the first frame assembly within the grid in an adjacent arrangement along the first axis. At least one of the mold or the plurality of machine heads is moveable along the first axis, the second axis, or both. At least one of the machine heads of the plurality of machine heads is moveable independently of one another along a third axis.

A method for manufacturing a microprojection unit (10) according to the invention involves: a microprojection tool forming step of forming a microprojection tool (1) by bringing a projecting mold part (11) into contact from one surface (2D) side of a base sheet (2A) including a thermoplastic resin, and thus forming a protrusion (3) that protrudes from another surface (2U) side, and withdrawing the projecting mold part (11) from the interior of the protrusion (3); a joining step of joining the one surface (2D) side of the base sheet (2A), in which the microprojection tool (1) has been formed, and a tip end of a base component (4); and a cutting step of cutting the base sheet (2A), to which the base component (4) has been joined, along a contour (4L) of the base component (4) at a position more inward than the base component's contour (4L) in a planar view of the base sheet (2A) as viewed from the microprojection tool (1) side, to manufacture a microprojection unit (10).

Method for producing a spray wall drilled with a network of holes for the pressurised fluid substance to pass through so as to be sprayed in fine droplets. The method includes the steps of (a) moulding a nozzle having a front wall integrally formed with an assembly wall, the assembly wall surrounding the front wall, the front wall having a curved initial configuration upon removal from the mould; (b) drilling the curved front wall with a network of holes having a defined initial orientation; and (c) deforming the drilled curved front wall into a final spray configuration defining a spray wall, the defined initial orientation of the holes being subsequently modified.

A forming module for forming a composite laminate part over a tool is provided. The forming module comprises a base, a ply carrier control assembly adapted for controlling the position of a flexible ply carrier on which composite resin plies are mounted, and a head section mounted on the base and adapted for automatically forming the composite resin plies from the ply carrier onto the tool.

An additive manufacturing machine and associated method for making a part layerwise by firstly using additive manufacture to make a mold to define a space for the layer, and secondly filling the space with a paste to make a layer of the part. The machine comprises a first mold forming station with inkjet nozzles to form the mold using standard 3D printing, and a second paste dispensing station distanced from the first station, with a dispensing die slot for dispensing paste into the space to form a layer. The machine operates on multiple parts simultaneously, each being conveyed along a path through the stations.

Methods, apparatus, and systems for cutting material used in fused deposition modeling systems are provided, which comprise a ribbon including one or more perforations. Material is passed through at least one perforation and movement of the ribbon cuts the material. A further embodiment comprises a disk including one or more blade structures, each forming at least one cavity. Material is passed through at least one cavity and a rotational movement of the disk cuts the material. A further embodiment comprises a slider-crank mechanism including a slider coupled to a set of parallel rails of a guide shaft. The slider moves along a length of the rails to cut the material. Yet another embodiment comprises one or more rotatable blade structures coupled to at least one rod. The rotation of the blade structures causes the blade structures to intersect and cut extruded material during each rotation.

A method of forming a nipple for a baby bottle, comprises: forming a lower conical wall section; forming a higher conical wall section molded above the lower conical wall section; preventing deformation of the higher conical wall section; and cutting an opening through the higher conical wall section into an interior section of the nipple.

A hollow molded article having a joining site where two or more split objects are welded by plastic welding and comes into contact with pressurized hydrogen, wherein an average spherulite size in a portion which is 500 μm deep inside from a surface of the hollow molded article is 20 μm or less, and a tensile strength of a test piece containing the joining site of the hollow molded article is 80% or more based on a tensile strength of a test piece not containing the joining site of the hollow molded article.

The present invention is an optically clear, curable adhesive including a polyvinylbutyral, a polyurethane (meth)acrylate, a (meth)acrylate monomer, and a photoinitiator. The polyvinylbutyral has a dynamic viscosity of between about 9 and about 13 mPa.Math.s and a polyvinyl alcohol weight percent of less than about 18%. The polyurethane (meth)acrylate includes the reaction product of a diol, at least one diisocyanate, and a hydroxyfunctional (meth)acrylate or an isocyanatofunctional (meth)acrylate. When the optically clear, curable adhesive is placed between two transparent substrates and made into a laminate, the laminate has a haze of less than about 6%, a transmission of greater than about 88%, and an optical clarity of greater than about 98% when cured. The optically clear, curable adhesive also has a peel adhesion of at least about 100 g/cm based on ASTM 3330 when cured.
