METHOD OF MANUFACTURING A STABILIZER BAR WITH A RUBBER BUSH

Provided is a method of manufacturing a stabilizer bar with a rubber bush including manufacturing a rubber bush without an intermediate plate by subjecting a rubber composition containing butadiene rubber and natural rubber as a polymer to vulcanization molding; applying a thermosetting adhesive onto at least one of an inner peripheral surface of the rubber bush and an outer peripheral surface of the stabilizer bar, to thereby form a thermosetting adhesive layer; inserting and fitting the stabilizer bar into the rubber bush; holding the rubber bush with a fixing jig such that the rubber bush is compressed at a rate of 0% to 5%, at 25° C., in a direction of the stabilizer bar fitted into the rubber bush; and heating the rubber bush in the state to cure the thermosetting adhesive, to thereby bond and fix the rubber bush onto the stabilizer bar.

Welding head

20220040794 · 2022-02-10 · ·

A resin pipe 30 and a resin member 31 are fixed to a setting portion 5 provided on the front side of a base 6, and a timing pulley 13 which is provided on the back side of the base 6 and to which a light emission unit 3 is attached is rotated. As a result, the light emission unit 3 applies laser light 20 to a junction 32 between the resin pipe 30 and the resin member 31 while revolving around the junction 32. This makes it easy to fuse and join the entire outer circumferential surface of the resin pipe 30 with the entire inner circumferential surface of the resin member 31, which are variously shaped and sized.

20220161952 · 2022-05-26 ·

A method for producing a package comprising a formed part having at least one product cavity, and a lidding film covering the at least one product cavity, comprises the steps of: (a) defining a seam; (b) dividing the seam into a plurality of sections; (c) determining a pull-off force for pulling the lidding film from the formed part at least for a first section; and (d) sealing the lidding film to the formed part by means of a sealing device, wherein at least one first sealing temperature is selected for the first section based on the pull-off force determined according to step (c).

Apparatus for manufacturing hair cap
11737505 · 2023-08-29 ·

Proposed is an apparatus for manufacturing a hair cap. A rubber band mounting unit is formed on one side of the top surface of the workbench. A rubber band conveying unit is formed on the top surface of the workbench and grips the expanded rubber band. A nonwoven fabric cutting unit is formed on the other side of the top surface of the workbench to cut a nonwoven fabric. A nonwoven fabric fusing unit couples the rubber band, conveyed by the rubber band conveying unit, to the nonwoven fabric. A driving unit makes the rubber band conveying unit reciprocate to the rubber band mounting unit or the nonwoven fabric fusing unit. A collecting unit grips and collects the fused hair cap. Processes for placing the rubber band on the peripheral edge of the nonwoven fabric and bonding same are performed rapidly in succession.

Process for joining overlapping thermoplastic membrane components

A method of joining overlapping thermoplastic membrane components in which a first thermoplastic membrane component and a second thermoplastic membrane component are positioned in overlapping relationship between a pair of complementary molding surfaces, with at least one of the complementary molding surfaces being defined by an electrically conductive metal susceptor. Heat is generated in the metal susceptor and transferred by thermal conduction from the metal susceptor to overlapping portions of the first and second thermoplastic membrane components to locally melt and coalesce at least a portion of the thermoplastic material of the first thermoplastic membrane component and at least a portion of the thermoplastic material of the second thermoplastic membrane component. The molten thermoplastic material of the first and second thermoplastic membrane components forms a zone of coalesced thermoplastic material that, upon cooling, forms a solid weld joint that fusion welds the first and second thermoplastic membrane components together.
