An asymmetric mold core for forming curved floor openings in pallets is taught. The mold core contains: a base, the base attachable to a frame in a rotomold, a bottom section integral at a distal end to the base, the bottom section comprising a bottom convex curve having a bottom convex curve radius and a bottom convex curve rotational center, a top section integral at a distal end to the base, the top section comprising a top convex curve, the top convex curve having a top convex curve radius and a top convex curve rotational center, the top convex curve radius being different from the bottom convex curve radius and the top convex curve rational center differing from the bottom convex curve rotational center; a first side section, the first side section positioned and integral at a distal end to the base and positioned between and integral with the bottom section and the top section; a second side section the second side section positioned and integral at a distal end to the base and positioned between and integral with the bottom section and the top section, the second side section positioned parallel to the first side section; and a face.

Cauls and methods of using the same are provided. The caul includes a reinforcement material having one or more elastic fibers and a polymer having one or more shape memory polymers. The caul is operable to transition from a rigid state to an elastomeric state and from an elastomeric state to a rigid state in response to stimuli. Methods of using cauls to produce composite articles involve positioning one or more fiber layers between a caul and a cure mold surface when the caul is in a rigid state. The fiber layers, caul, and cure mold surface may be covered with a sealed barrier and a pressure gradient may be applied. Before, after, or before and after performing the vacuum the fiber layers may be impregnated with resin. The fiber layers may be cured, which may provide a stimulus to transition the caul from a rigid to an elastomeric state.

A method for forming a building includes obtaining a mould, spraying a first spray material onto the outside of the mould so that it sets generally in the shape of the mould to provide a core. The core has side walls, and end wall integral with the side walls and a roof integral with both the side walls and end wall. A second spray material different to the first spray material is sprayed onto the inner and outer surfaces of the core to give it a rigid skin.

A method of manufacturing a textured former and a glove made therefrom, wherein the method comprises preparing a hand-shaped ceramic greenware, scanning the hand-shaped ceramic greenware to generate a digital 3D hand-shaped greenware model, modelling a pair of stencil covers with curvy texture line based on the digital 3D hand-shaped greenware model, printing the stencil covers, creating a curvy palm texture on the hand-shaped ceramic greenware with the aid of the stencil covers, firing the hand-shaped ceramic greenware with curvy palm texture in a kiln and dipping the hand-shaped ceramic former with curvy palm texture in an aqueous colloidal dispersion to produce glove with curvy palm texture.

Devices and methods are provided for making a variable textured breast implant when used in conjunction with a breast implant mandrel having a molding surface and a stem depending therefrom.

A filming method of probe by filling way and the probe made by the filming method, the method includes following steps: spraying hydrophilic matrix material on the rigid member; injecting liquid polyethylene glycol into the inner, letting the polyethylene glycol coagulate; cutting out the solid polyethylene glycol, letting the cutting surface and the perimeter of the rigid member to be formed in a smooth plane; letting the wedge end of the rigid member insert a liquid latex vertically for immersion, picking up the rigid member and dripping residue, air drying the adhesive layer of the rigid member; upward setting the wedge end of the rigid member, and letting the latex film be heated, melting the solid polyethylene glycol and letting the polyethylene glycol drain away. The method can minimize the nonlinear deviation, simplify the technological process, improves product quality and manufacturing efficiency.
