The present disclosure relates to a method of manufacturing a model car body, including preparing a steel mold comprising a core plate with an inner core, a top plate and at least two side plates; attaching at least one pre-fabricated plastic block to a side of the inner core of the core plate; combining the core plate, the top plate and the at least two side plates with each other, wherein a cavity is formed among the top plate, the side plates, the inner core of the core plate and the at least one pre-fabricated plastic block; injecting melted plastic material into the cavity, wherein the melted plastic material is filled with the cavity and the at least one pre-fabricated plastic block is encased by the melted plastic material; solidifying the melted plastic so as to form the model car body, wherein the at least one pre-fabricated plastic block is integrated with the plastic model car body; separating the core plate, the top plate and the at least two side plates from each other; and releasing the model car body with the at least one pre-fabricated plastic block from the mold.

An example mandrel for processing a part is described including a plurality of elastomeric components aligned end to end and spaced apart linearly to form a segmented mandrel body, and compressible interconnections positioned within spacing between adjacent elastomeric components and abutting the adjacent elastomeric components. The compressible interconnections allow the plurality of elastomeric components to expand axially due to thermal expansion resulting in a distribution of pressure. An example method for fabricating a composite part is also described including placing a base composite layer into a cavity of a tooling surface, inserting a mandrel into the cavity of the tooling surface such that the base composite layer is between the mandrel and the tooling surface, applying a skin to the mandrel and the base composite layer forming a package, enclosing the package in a vacuum bag and curing, and removing the mandrel from the cavity of the tooling surface.

Provided is a resin composition capable of providing a three-dimensionally photofabricated object having high heat resistance while having water solubility. The resin composition is a resin composition for three-dimensional photofabrication containing a reactive monomer, a water-soluble polymer, and a photopolymerization initiator. A cured product of the resin composition has a main tan ? peak temperature of 80? C. or higher. A 1-mm-thick cured product of the resin composition exhibits a remaining thickness of 0.7 mm or smaller after 5-hour immersion in water that is at room temperature.

A method of making a fluid manifold may include the use of a mold, a mandrel, and a distal support. A fluid manifold may include a primary channel, a plurality of secondary channels, and a distal channel, and the primary channel may be coterminous with the distal channel.

A method for manufacturing a tire T comprises a step for forming a green tire on the outside of a rigid core mold 2, a step for vulcanization-molding and obtaining a tire-accompanying rigid core mold G, a step for setting, at an assembly station P3, a core 5 taken out from the tire-accompanied rigid core mold G, and a removal and assembly step for removing one core segment 3 from the tire T by moving in inwardly in the tire radial direction from the tire-accompanying rigid core mold G and mounting it on the core 5 set at the assembly station. The removal and assembly step is performed for every core segment in the tire, whereby a rigid core mold 2 is assembled at the assembly station P3, while removing the rigid core mold 2 from the tire T.

One aspect of the present disclosure is a rod-shaped molding core used in production of a long and hollow molded object. The molding core includes divided pieces that assemble to form a rod-shaped body. The divided pieces include rod-shaped first, second, third, fourth, and fifth divided pieces. An outer peripheral surface of the first divided piece is entirely surrounded by the rest of the divided pieces in an assembled state. The second and third divided pieces are arranged to abut and interpose the first divided piece along a first direction orthogonal to a longitudinal direction and form a part of an outer peripheral surface of the rod-shaped body. The fourth and fifth divided pieces are arranged to abut and interpose the first divided piece along a second direction orthogonal to the first direction and form a part of the outer peripheral surface of the rod-shaped body.
