A method for forming an object comprises the steps of: providing a mould comprising a first and a second mould part opposite to each other, a part selected from between the first mould part and the second mould part comprising a plurality of sectors for shaping a lateral portion of the object, the sectors delimiting a variable-volume forming region of the mould; positioning a dosed amount of mouldable material between the first and second mould parts while the mould is in an open position; displacing the first mould part and the second mould part towards each other in a moulding direction, to define between the first mould part and the second mould part a closed forming chamber bringing into contact respective abutment surfaces of the first mould part and the second mould part, the abutment surfaces extending transversely to the moulding direction.

A method of manufacturing a microfluidic or microtiter device, the method comprises fabricating, by a single compression injection molding operation, a microfluidic or microtiter device having one or more indentations, in which a base thickness of the one or more indentations is less than 400 m. In embodiments, the fabricating step comprises: forming a mold cavity; filling the mold cavity with molten material; closing the mold cavity; and driving one or more molding formations complementary to the one or more indentations into the mold cavity.

Provided is a method of molding, by using a mold, a component including a metal plate and a thermoplastic resin containing a thermoplastic resin arranged on a surface on one side of the metal plate, the mold including at least a movable mold and a fixed mold including a support portion. Specifically, the molding method includes: an arranging step of arranging a premolded metal plate within the mold; a fixing step of fixing the metal plate by pressing the metal plate against the movable mold with use of the support portion; and a molding step including forming a cavity between the fixed mold and the metal plate by closing the mold, bringing the thermoplastic resin into close contact with the metal plate, and forming an exposed portion by exposing the metal plate out of the softened thermoplastic resin with use of the support portion. With this, without leakage of the thermoplastic resin, a joint region to a metal surface of another component can be reliably secured.

A method includes providing a collection of particulate material and forming a first article therefrom. Forming the first article includes forming an outer shell with an outer surface that defines an outer periphery of the first article; forming a relief area of the first article that supports the outer shell, including forming a relief void in the relief area; and collecting a collection of the particulate material within the outer shell during formation of the first article. Moreover, the method includes encasing the first article with an outer member. The outer member defines an internal cavity with an internal surface that corresponds to the outer surface of the outer shell. The method further includes heating, which deforms the first article selectively at the relief void.

A toothbrush comprised at least one unitary brush head having a base and at least one filament and extending therefrom and having a free end terminating with a tip, wherein the filament has a length of from 6.0 mm to 20.0 mm between the base and the free end, and wherein the unitary brush head is made from a plastic material that has a melt flow rate of not greater than about 30 g/10 min measured in accordance with ISO 1133.

A molded article formed from a blend, the blend comprising: from 1 wt. % to 30 wt. % of a polypropylene; and from 60 wt. % to 99 wt. % of an ionomer formed from a partially neutralized precursor acid copolymer, wherein the precursor acid copolymer (a) comprises copolymerized units of ethylene and 5 wt. % to 30 wt. %, based on the total weight of the precursor acid copolymer, of copolymerized units of an ?,?-ethylenically unsaturated carboxylic acid having 3 to 8 carbon atoms, and (b) has a melt index, I2, (according to ASTM D1238 at 190 C, 2.16 kg) of 10 g/10 min to 4,000 g/10 min, and wherein about 25% to about 65% of the acid groups derived from the ?,?-ethylenically unsaturated carboxylic acid of the precursor acid copolymer are neutralized.

A lens mount apparatus comprising a first lens component and a second lens component joined integrally with the first lens component, resulting in mechanochemical attachment of the second lens component with the first lens component to produce the unitary lens mount apparatus without compromising the lens mount apparatus optics, wherein at least one of the first and second lens components is an optical lens.

Method of making golf ball comprising aligning thermoformed depressions with dimpled mold cups and applying sufficient heat and suction to the thermoformed depressions without exposing any preselected subassembly to the heat and suction to soften the polymeric material of each thermoformed depression and draw air outward from a volume located between an inner surface of the dimpled mold cup and an outer surface of the thermoformed depression to form a thermoformed pre-form half-shell having an outer surface with the size, shape and contour of the inner surface of the dimpled mold cup(s) and an inner surface with the size, shape and contour of the outer surface of a preselected subassembly. Afterwards, a preselected subassembly is loaded between a pair of thermoformed pre-form half-shells and molded under sufficient short-term heat and suction to form the golf ball. The thickness of each thermoformed depression and thermoformed pre-form half-shell may be tapered.
