A method for making teat unit including providing a support body and a securing part, the support body including a plurality of recesses, forming a teat by overmolding the teat over the support body and over the recesses of the support body so that the teat covers the recesses, and overmolding the teat over an upper edge of the securing part, thereby forming a connection between the securing part and the support body which connects the securing part to the support body. In another method, the support body and the securing part are already one single piece and the teat is overmolded at least over the support body.

A method for manufacturing a composite part (100) for covering, sealing, trimming, or retaining a component of a vehicle, wherein the composite part (100) has a main body (110) with a vehicle side surface (111) and is made of a first polymer, and has a mounting pin (130) configured to engage in a form fitting manner and is made of a second polymer, wherein the second polymer has a higher formability than the first polymer, comprises the steps of extrusion molding of the main body (110) and injection molding of the mounting pin (130). This is done in such a manner that the mounting pin (130) is being integrally bonded to the main body (110) on the side of the vehicle side surface (111).

A method is provided for producing a multi-section plastic component in which a first plastic injection-molded individual part and a second plastic injection-molded individual part are formed. The plastic injection-molded individual parts are joined by injecting a plastic moulding compound. The plastic molding compound is a non-elastomeric thermoplastic and forms a plastic connecting component following a curing process. The plastic injection-molded individual parts and plastic connecting component are then at least partially painted.

In at least one embodiment, the present disclosure provides a vehicle seat assembly comprising a cushion having an “A” surface and a “B” surface, a central portion, and two bolster areas, with each bolster area being adjacent the central portion, with the cushion having a plurality of intrusions extending from the “A” surface towards the “B” surface to form a hardness gradient between at least one of the bolster areas and the central portion of between 5% to 25%, the plurality of intrusions comprising a plurality of pairs of patterns, each pair of patterns comprising a first pattern spaced apart and opposingly and inversely facing a second pattern.

The present invention concerns a chemical mechanical polishing pad having a polishing layer. The polishing layer contains an extruded sheet. The extruded sheet is prepared by extruding a compounded photopolymerizable composition followed by exposure to UV light.

Multilayer polymer sheets are provided, as well as related methods, systems, and appliances.

To solve the above problem, a pouch forming apparatus according to an embodiment of the present invention includes: a die in which a forming space is recessed inward from a top surface thereof; a partition wall partitioning the forming space into first and second forming spaces; a stripper disposed above the die and configured to descend to contact the die with the pouch film therebetween to fix the pouch film to be seated on a top surface of the die; and an electromagnetic force generation part disposed above the forming space and configured to generate electromagnetic force and configured to apply the electromagnetic force to the forming space.

A pump liner for a centrifugal pump wherein the pump liner comprises a main pumping chamber, an inlet to the main pumping chamber and a discharge outlet extending from the main pumping chamber, wherein the pump liner is formed from at least two elastomeric compounds including a first compound and a second compound, the first compound having a different hardness to the second compound and wherein the liner is composed of the second compound at locations which in use are subject to erosive, impingement and/or directional wear.

An expansion joint seal includes a seal body and a plurality of seal caps, wherein the seal body is made of a material having a first hardness, and the seal caps are made of a material having a second hardness that is greater than the first hardness. The seal body includes a plurality of walls that form hollow cells. The seal body includes a plurality of traffic bearing surfaces that are separated from one another by grooves and are thereby discontinuous relative to one another. The hollow cells and the grooves allow the seal body to expand and contract as an expansion joint increases and decreases in size due to thermal and/or load variations. The seal caps cover the traffic bearing surfaces of the seal body, such that each of the traffic bearing surfaces of the seal body is covered by a separate one of the seal caps.

An inventive transfer roller (1) is made of a foam formed from an electrically conductive rubber composition containing an electrically conductive rubber, a crosslinking component, and a foaming agent including OBSH and 0.25 to 2.5 parts by mass of sodium hydrogen carbonate based on 1 part by mass of OBSH, and has an Asker-C hardness of not lower than 25 degrees and not higher than 35 degrees and an average foam cell diameter of not greater than 120 μm. Therefore, the transfer roller is flexible with a lower rubber hardness, and has smaller foam cell diameters. An inventive production method includes the steps of: forming the electrically conductive rubber composition into a tubular body; and maintaining the tubular body at a temperature of not lower than 120° C. and not higher than 140° C. to foam the rubber by a single-stage foaming process.
