An injection molded component includes a wall that has an inner wall surface and an outer wall surface. A sensor is molded into one of the inner wall surface and the outer wall surface. A channel is at least partially surrounding the sensor.

An asymmetric mold core and method for use 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, and a top section integral at a distal end to the base. Both the top section and the bottom section have convex radial curve shape, but the top section curve and the bottom section curve are positioned by having different centers of rotation so when the core is actuated it is only actuated around the center of rotation about the bottom curve which causes the top cure to drop away from the upper molded surface.

A molding method is provided for molding composite materials. The molding method molds a stack of composite materials formed by impregnating a base material with resin. The molding method includes providing a first resin with a photocuring property and providing a second resin with a thermosetting property. The first resin contained in a first composite material is cured by irradiating the first composite material with light, then the second resin is cured by heating the second resin contained in a second composite material. The curing of the first resin contained in the first composite material is completed before starting the curing of the second resin contained the second composite material that is adjacent to the first composite material of a surface layer.

The invention is directed to an overmolded two-component friction element in a plastic pallet and to a method for forming the pallet. The friction element includes a rigid outer carrier member and an elastomeric material that is exposed at one or more ends. The friction element is first formed in an injection mold, and then is placed in a pallet mold. Resin is injected into the pallet mold around the sides of the friction element leaving the exposed elastomeric material form part of the pallet surface.

A continuously extruded unitary blank (CUBE) has a top, a bottom, two sides and at least one webbing there between parallel to the two sides. The CUBE has a front cut end and a rear cut end which define two open face channels to accommodate the forks of a fork lift and pallet jack. Two spaces are manufactured in the two sides and in the at least one webbing to accept a lateral insertion and a lateral removal of the forks. Chamfers are manufactured in edges of the cutouts to facilitate the insertion and the removal of the forks from the pallet. Chamfers are also manufactured in the front and rear cut ends to facilitate accommodation of the forks. Voids are manufactured in the bottom to allow pallet jack wheels to pass into the pallet and rest on a surface for a lifting of the pallet from the surface.

A container carrier and manufacturing method therefore are provided. The container carrier may include a plurality of annular structures connected by bridges. The annular structures may include a side wall formed of side wall portions separated by side wall voids. Each side wall portion has an upper and a lower side wall segment joined at a ledge, with the upper side wall segment having a smaller diameter relative to the lower side wall segment of the side wall portion. Flanges are positioned at the bottom of each side wall void to collectively engage containers. The bottom portion of the lower side wall segment has an inner diameter that is larger than the outer diameter of the upper side wall and smaller than the outer diameter of the ledge such that the bottom of a first container carrier will rest upon the ledge of a second, same-shaped container carrier when stacked.

A pallet includes base members, connecting bars, and a loading plate. The connecting bars secure the base members to form a pallet frame. The loading plate is fixed on the pallet frame. The size of the pallet can be adjusted in length and width so as to be adjusted freely and conveniently according to practical requirements. Consequently, the cost for manufacturing the pallet can be reduced. In addition, when one base member is damaged or missing, the damaged or missing base member can be replaced by a new base member. Therefore, the pallet can be used for more times, allowing the cost reduction in manufactory. Furthermore, the base members and the connecting bars are connected with each other to form the pallet frame which is rigid and has high structural strength, such that the pallet frame would not deform and is safe when used for handling and transporting materials.

A composite pallet is made of concrete. The concrete material can include various concrete mixtures, such as Fiber Reinforced Concrete (FRC) or an Engineered Cementitious Composite (ECC). It also can include microspheres. The concrete material can be cast in a mold or formed via an extrusion process and then cured. The pallet components can include a core material that can form various voids or cavities. The core material can include polystyrene foam, and the foam forms a honeycomb, which is then filled with the concrete material. The concrete material can also be dyed to create different colors to identify the pallets. The pallets can further include plastic and/or rubber bumpers on the corners and/or edges to prevent or minimize chipping. The resulting pallet can be cured using carbon dioxide (CO.sub.2) curing which reduces the cure time to about an hour or less.
