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.

The application relates to an adjustable moulding tool and corresponding model production method, including following process steps: moving rods towards the said chamber through the said chamber's holey surfaces manually or via mechanisms in increments numbers of which are calculated through computer programs or manually, after the formation of the emptiness in the shape of the model, pouring of the material in a manner to fill the emptiness, heating and cooling or applying other processes in accordance with the characteristic of the poured material to enable that material takes the desired monolithic shape, after material takes the form of the model monolithically, making the casting chamber free of the rods, which have initially been moved towards the casting chamber with the purpose of the formation of the emptiness, by moving the rods in the reverse directions and taking out the produced model through an openable surface of the said chamber.

A seal member formed in a line shape having ends is inserted in a seal groove formed on at least one of adjacent side surfaces of segments. A lip portion is provided on a seal upper portion of the member so at least a tip end thereof projects to an outside of the seal groove when the member is inserted in the groove. The seal member is hollow or includes a concave portion on at least a seal bottom portion thereof. When assembling the segments as a single structure, the adjacent side surfaces of the segments are coupled to each other, and the seal member is crushed in a cross sectional direction by the side surface of the other segment to seal between the segments. With this, complication of manufacturing steps can be suppressed or avoided while realizing a satisfactory sealed state between the adjacent segments of a mold.

The molding element has a molding surface for forming a contact face of the contacting elements and a groove forming rib portion for forming the groove. The groove forming rib portion has opposed rib side faces for forming opposed groove side faces and a rib top face connecting the rib side faces for forming a groove bottom. The groove forming rib portion provides at least one space opening to at least one of the rib side faces and/or to the rib top face and an insert is received in the space. The insert is composed of a plurality of thin plates stacked in a direction along which the rib extends and comprises at least one notched plate of thickness t1 including at least one notch for forming a flexible fence of the closing device; and comprises at least one support plate of thickness t2 without notch.

An injection mold for the manufacture of an axisymmetric part of composite material including a mandrel supporting a fibrous preform and including an annular wall, and a plurality of counter-mold angular sectors assembled on the mandrel and intended to close the mold and to compact the fibrous preform wound on the mandrel. Each angular sector includes an annular base intended to come into contact with the fibrous preform. The annular base extends between the first and second lateral edges in a circumferential direction, the first lateral edge of the annular base of an angular sector being in contact with a second lateral edge of the annular base of an adjacent angular sector.

An injection mold, in particular for encapsulating rotors of electric machines, has a mold, wherein the mold has an arrangement of mold segments. The arrangement forms, along a longitudinal axis, a cavity for a component to be arranged. An exchange unit is provided, which is designed to remove at least one mold segment from and/or insert at least one mold segment into the arrangement, with the result that a size of the cavity can be changed.

A mold insert and method of using a mold insert to make a composite part. The mold insert is configured to make a composite part from composite material. The mold insert is configured to be attached to a mandrel. Once attached, the composite material is applied to the mandrel over the mold insert, stringers, and bladders. The composite material is then cured on the mandrel. The mold insert can then be removed from the mandrel.

A preform mould (90) is provided for manufacturing a preform for a wind turbine blade. The preform mould (90) comprises one or more support elements (70) and a plurality of strip members (88) comprising a top surface, a groove (64), a tongue (66), and preferably a sealing member arranged in the groove (64). The strip members (88) are arranged in juxtaposition such that the tongue (66) of a strip member (88) is releasably fixed within the groove (64) of an adjacent strip member (88).

A portable molding system is configured for forming insulation on pipes. A set of transportable process modules are configured to be shipped to a molding site, operatively connected together at the molding site to form a site-installed molding system, and subsequently disconnected for transport to another site. The set of transportable process modules includes one or more resin preparation modules configured to prepare resin for being formed into insulation on the pipes. One or more mold modules are configured to define a mold cavity. The one or more mold modules are configured to hold a pipe in the mold cavity, to receive resin prepared by the one or more resin preparation modules in the mold cavity around the pipe, and to form said resin received in the mold cavity into insulation on the pipe.

A method for manufacturing a composite includes providing a first template including a cutout for a first layer of the composite, disposing the first layer in the cutout, and disposing a tablet, provided with an adhesive, on the first layer such that the first layer adheres to the tablet. Next, the tablet is removed, together with the first layer adhered thereto, from the cutout, and an adhesive is applied to a side of the first layer facing away from the tablet. A second template is provided that includes a cutout for a second layer of the composite, and then the second layer is disposed in the cutout. The tablet, together with the first layer adhered thereto, is disposed on the second layer disposed in the cutout of the second template, and the tablet is removed, together with the composite produced from the first and second layers, from the second template.
