摘要:
A method for the manufacture and decoration of a mineral-filled resin shower tray with an external coating, including the steps of applying an external coating layer on the internal surface of a mould, casting a mix of resin and mineral filler on the mould, curing and drying the mix, and including the prior steps of disposing on the internal surface of the mould cavity a transfer film including on one of the sides thereof a pattern printed in ink, vacuum thermoforming the transfer film against the internal surface of the mould cavity, and the subsequent step of removing the film from the surface of the mineral-filled resin shower tray with an external coating.

The invention relates to a sanitary basin molded part, for example a kitchen sink, a washbasin or a shower tray, having a main part (10) which has the shape of the sanitary basin molded part and ensures the mechanical stability thereof, characterized in that on the visible side of the sanitary basin molded part a covering layer (20) is arranged in at least one surface region on top of the main part (10), which covering layer comprises a fibrous tissue (24) saturated with a cured binding agent. The invention further relates to a method for producing a sanitary basin molded part of this kind.
摘要:
A welded joint for structural component having two or more portions fused together at a weld line. An adhesive layer is placed between the two or more portions at the location of the weld line and a conductor is placed between the two or more portions in operable contact with the adhesive. Energy is transmitted through the conductor and into the adhesive layer to activate the adhesive layer and create the weld line that defines the welded joints between the two or more portions. The welded joint of the structural component allows energy to be injected into the adhesive layer via the conductor in order to cause the adhesive layer to activate from the inside of the adhesive outward. The conductor can be placed adjacent the adhesive layer or within the adhesive layer in order to cause the adhesive to be activated from the inside outward.

A showerhead for a low flow rate may employ one or more of a showerhead housing, a showerhead engine, a flow restrictor and a flow regulation device. The showerhead engine may be moveably connected to the showerhead housing. The showerhead engine may include a back member, an intermediate member, and a front member defining various fluid chambers and apertures that allow for one or more spray modes. The showerhead may include a flow control device to selectively reduce flow to the showerhead engine. The flow control device may also be selectively pause fluid flow for more than one spray mode. The showerhead may include a flow restrictor. The flow restrictor may limit a maximum fluid flow rate of a fluid delivered from the showerhead engine to approximately 1.5 gallons per minute.

An apparatus for forming a bathtub liner over an existing bathtub comprising a container, a seal, a heating element, and a pressure increasing element. The container defines a cavity. The seal is associated with cavity and is capable of forming a substantially continuous seal with a bathtub liner. The heating element is capable of heating the cavity, and in turn, the liner. The pressure increasing element is capable of increasing the pressure within the cavity, to in turn, force a bathtub liner outwardly, away from the cavity. Upon positioning of the liner and apparatus over an existing bathtub the pressure increasing element will force the liner toward and into contact with the surfaces of the existing bathtub.

A customizable skirt-forming member is disclosed, for use in high stress acrylic tub formation operations. The member generally has a rigid forming wall, at least one adjustable wing hingeably associated with the forming wall, and means for altering the pitch of the at least one wing, relative to the sidewall, so as to simultaneously alter a hinge angle therebetween. The member allows for customized, angled formed front tubs to be formed, while ensuring that the stresses of system operation do not alter the intended angles.A toggle-nut structure is additionally disclosed, which ensures the maintenance of the relative positions of the angled walls of the skirt-forming member.
摘要:
A process of fabrication of a shower tray wherein it comprises the steps of: selecting a plate in thermoplastic material; cutting at least one corner; heating the plate to soften it; forming the plate on a mold to raise the convex limit at the at least one corner and the edges between the cuts, the junction between a central portion of the plate, forming a bottom, and each raised edge being curved; and joining raised edges at each corner.

A molded arm for a showerhead may be configured to connect a showerhead to a fluid supply, and may be in the form of a molded body defining an inlet, an outlet and an interior passage providing fluid communication between the inlet and the outlet. An arm assembly may be configured to connect a showerhead to a fluid supply, and may include: a molded arm body defining an inlet, an outlet and an interior passage providing fluid communication between the inlet and the outlet; and a separate attachment component configured to cooperate with the molded body and to engage a structure connected to a fluid supply. A method of making an arm for connecting a showerhead to a fluid supply may include molding an arm body to define an inlet, an outlet and an interior passage between the inlet and the outlet.

A first aspect of the invention relates to the manufacture of disparate workpieces by the process of injection molding using a single base tool. The tool is made up of cavity and core halves, and each half is made up of separate, removable/interchangeable, inserts which, when combined in a particular order, form the workpiece-forming surface. All or any number of the inserts may be replaced with other inserts to alter the workpiece-forming surface and allow a large number of differently shaped workpieces (i.e. having different surface features and shapes) to be formed from a single base tool. In another aspect of the invention, the inserts are connected to respective thermally conductive cavity and core mounting plates, which are in turn connected to respective cavity and core heating/cooling plates so that insert-mounting holes need not be made in the heating/cooling plates.
