An injection mold assembly for injection molding an object includes a first mold tool having a first tool surface and a second mold tool having a second tool surface. The first and the second tool surfaces are cooperatively configured to define a mold cavity between the tool surfaces for an injection molding of an object. The first mold tool has a tool element with a first side that has the first tool surface, and with a second side opposite the first side. Multiple fins extend from the second side of the tool element. A base supports the fins. The tool element, the fins and the base define a coolant flow cavity at the second side of the tool element. A method of designing the mold assembly is also disclosed.

To solve the above problems, a pouch molding method according to an embodiment of the present invention includes: a seating step of seating a pouch film on a top surface of a die; a stripper descending step of allowing a stripper disposed above the die to descend; a fixing step of fixing the pouch film using the stripper; a molding preparation step of allowing a Blank holder disposed at a central portion of the die to ascend to contact one surface of the pouch film and allowing a punch disposed at a central portion of the stripper to descend to contact the other surface of the pouch film; and a molding step of allowing the punch and the Blank holder to descend along with each other to form a cup part in the pouch film.

Systems and methods are provided for composite part fabrication. One embodiment is a method for fabricating a composite part. The method includes selecting a tool with sides made of a core material in a desired size and shape, disposing a preform of a fiber reinforced material that surrounds the tool, resulting in a lamina assembly comprising the preform and the tool, heating the tool and the preform, co-bonding the tool to the fiber reinforced material within the lamina assembly, and hardening the preform and the tool into a hybrid composite part.

A hot stamping apparatus and a hot stamping method are for collectively decorating a plurality of decoration objects using a decorative sheet. In a hot stamping apparatus, an upper chamber and a lower chamber are partitioned by a partition sheet and pressing bodies, so that decorative sheet pieces can be used instead of a decorative sheet having a large area. Then, by using the decorative sheet pieces, local thermal deformation can be prevented. A usage amount of the decorative sheet can be reduced, and three-dimensional decoration can be implemented as needed on a portion requiring decoration.

A method for transferring a negative structure of a surface of an inner wall (51) of a blow molding tool (1) onto a surface of a plastic container. The method comprises the steps of heating at least one region (511) of a mold cavity (6) of a molding body (4) of the blow molding tool (1), on which the negative structure is formed, inserting a preform into the mold cavity (6), closing the blow molding tool (1), molding the plastic container by inflating the preform and bringing the preform to lie against the inner wall (51) of the mold cavity (6), cooling the region (511) by supplying a coolant through temperature control channels (54), and removing the plastic container from the mold.

A molding system for direct injection manufacturing of footwear. The molding system includes a mold cavity for receiving injection material for molding a sole part of the footwear. The system further includes a plurality of basic direct injection molds, each of which is attachable to injection molding equipment, and a plurality of sets of direct injection mold inserts, each set of direct injection mold inserts being configured to define at least part of an inner surface of the mold cavity when inserted in one of the plurality of basic direct injection molds. At least two of the plurality of basic direct injection molds differ from each other in size, corresponding to different ranges of sole part sizes.

A binder for an injection moulding composition including: from 40 to 55 volume percent of a polymeric base, from 35 to 45 volume percent of a mixture of waxes or a mixture of wax and palm oil, and at least 5 volume percent of at least one surfactant, wherein the polymeric base is formed of copolymers of ethylene and methacrylic or acrylic acid, copolymers of ethylene and propylene and/or maleic anhydride-grafted polypropylene, and polymers soluble in isopropyl alcohol, propyl alcohol and/or turpentine, and chosen from the group including a cellulose acetate butyrate, a polyvinyl butyral and a copolyamide, the respective quantities of the binder components being such that their sum is equal to 100 volume percent of the binder.

A curable resin composition comprising: (1) a urethane (meth)acrylate; (2) a reactive diluent selected from the group consisting of i) a hydroxyl alkyl (meth)acrylate monomer where the acrylate group, which is attached to the carbonyl group, is attached to a hydrogen or a methyl group and the carbonyl group is attached to the hydroxyl group thru an R2 alkylene group containing 2 to 18 carbon atoms per molecule.

A mold for casting a polymeric aircraft window panel includes a first mold half having a first mold surface, and a second mold half having a second mold surface. The first mold surface and/or the second mold surface have a shape conforming to a final shape for the major surfaces of the aircraft window panel. The first mold half and/or the second mold half can be formed of rolled, hydroformed, or stamped metal.

Method for producing crockery (460) filled with phase-change material, comprising the steps of pouring (110) liquid phase-change material into a mould, curing (120) of the phase-change material in the mould, packaging (130) the cured phase-change material in a package (330), drawing (140) a vacuum in the package filled with cured phase-change material, arranging (150) the package (330) filled with phase-change material against a wall (310) of a first part (510) of the crockery to be heated or cooled, arranging (160) a second part (520) of the crockery against the first part (510) of the crockery, such that the package (330) filled with phase-change material is enclosed by the first part and the second part of the crockery, and sealing (170) the first and second parts of the crockery arranged on each other, with sealing agent (570).
