A bonded object manufacturing apparatus is for manufacturing a bonded object in which a first object and a second object, which is more flexible than the first object, are bonded by a bonding agent, viscosity of which is variable, and includes: a bonding agent supplier that supplies the bonding agent to a first or second bonding surfaces; a thickening unit that increases the viscosity of the bonding agent; and a loading unit that applies a load to and deforms the second object against the bonding agent that closely adheres to the first bonding surface and becomes harder than the second object. In a method for manufacturing a bonded object, the first and second bonding surfaces are brought close to each other to hold the bonding agent therebetween, the bonding agent closely adheres to a required portion of the first bonding surface, and the second object is loaded and deformed against the bonding agent that closely adheres to the first bonding surface and is harder than the second object.

The present invention relates to a synthetic leather for a steering wheel cover of a vehicle, and a method for preparing the same. The synthetic leather including a fiber base layer (101) including a microfiber nonwoven fabric, an urethane porous layer (102) formed on the fiber base layer, a polyurethane resin skin layer (104) formed on the urethane porous layer, and prepared by polymerizing an isocyanate compound and a polyol compound including polycarbonate-based polyol, fluorine-based polyol and ester-based polyol, and an adhesive layer (103) for adhering the urethane porous layer and the skin layer.

In a preferred embodiment, a composite panel with a smooth outer surface, ready for painting with or without addition of primer, may be created by constructing a panel layup assembly upon a mold, the panel layup assembly including a composite panel having a core and a resin formulation, and a release film between the mold and the composite panel, where a smooth release surface of the release film is in contact with the composite panel upon construction; initiating curing of the composite panel at a first temperature within a lowermost ten percent of a curing temperature range of the resin formulation; continuing curing of the composite panel at a second temperature above the lowermost ten percent of the curing temperature range; and completing curing of the composite panel at a third temperature below the second temperature.

Thermoformed polymeric foam articles are described herein In some embodiments, the articles are made by a manufacturing method (e.g., a continuous process) which involves the extrusion and subsequent thermoforming of a blowing agent containing thermoplastic sheet. The thermoformed polymeric foam articles may have a lower density than the precursor sheet from which they are formed. In some but not all embodiments, the precursor sheet is a multi-layer sheet which includes at least one foam layer. In such embodiments, the thermoformed articles also include multiple layers and at least one foam layer.

An injection mold for a high-aspect-ratio double-layer cylindrical plastic part and a molding method using the same. The injection mold includes a support base plate. A movable mold fixing frame and a movable mold base plate are arranged at the middle of a lower surface of the support base plate through positioning screws. A lower core mold is matchingly provided at a center of an upper surface of the support base plate, and is provided with a lower semicircular cavity for accommodating an outer die barrel. One side of the lower semicircular cavity is open, and the other side is provided with a first end wall which is provided with a lower semicircular notch for an inner die rod to pass through. An upper surface of the lower core mold is provided with a positioning protrusion, a lower feeding groove, and a remaining groove.

A method is provided for maintaining resin in a system including a main feed tank and at least one vat, each of the at least one vats associated with a 3-D printing machine. The method includes the steps of: transferring resin from the main feed tank to the at least one vat; operating the associated 3-D printing machine in a build cycle; returning the resin from the at least one vat to the main feed tank; and repeating in a cycle the steps of transferring the resin, operating the 3-D printing machine, and returning the resin.

A composite charge is formed between two compression dies into a composite laminate stiffener. The stiffener is contoured along its length by contouring the dies. Wrinkle diffusers attached to, or embedded or incorporated into the tool surfaces of the dies, diffuse wrinkles formed on the inside radius of the stiffener during the contouring.
