A tool for fabricating a control surface is disclosed. In various embodiments, the tool includes a first block defining a longitudinal direction running between a leading edge end and a trailing edge end; a first sidewall spaced a first lateral distance from the first block to form a first closeout channel running in the longitudinal direction between the first block and the first sidewall; and a second sidewall configured to form a second closeout channel running in the longitudinal direction, the second closeout channel disposed laterally opposite the tool from the first closeout channel.

An example mandrel for processing a part is described including an inner core having a material with first thermal properties, and an outer layer surrounding the inner core. The outer layer includes a material with second thermal properties different than the first thermal properties to enable uniform pressure distribution within the mandrel. An example method for fabricating a composite part is described including placing a base composite layer into a cavity of a tooling surface, inserting a mandrel into the cavity, applying a skin to the mandrel and the base composite layer forming a package, enclosing the package in a vacuum bag and curing the base composite layer and the skin such that during curing a pressure due to thermal expansion of one of the inner core and the outer layer is distributed by the other, and removing the mandrel from the cavity of the tooling surface following the curing.

A core according to one aspect of the present disclosure is a core that is inserted into a space between a skin and a stringer in a step of integrally molding the skin and the stringer, the skin including fiber-reinforced resin, the stringer having a hat-shaped section that is open toward the skin. The core includes: a first die that extends along a longitudinal direction of the stringer and contacts the skin; and a second die that extends along the longitudinal direction of the stringer and is located at an opposite side of the skin across the first die. The second die includes a material that is softer than the first die. The second die includes a slit perpendicular to the longitudinal direction of the stringer.

A plastic faucet body and a die for molding the same are disclosed in present invention. The plastic faucet body comprises a left water inlet pipe and a right water inlet pipe, where a connecting cross-beam is disposed between the left water inlet pipe and the right water inlet pipe, the left water inlet pipe and the right water inlet pipe are embedded with a threaded copper pipe, respectively, the copper pipes are formed integrally with the plastic faucet body by means of a single stage process and are in communication with the corresponding left water inlet pipe and the right water inlet pipe, respectively.

A pallet is taught having two openings on at least one side of the pallet, the two openings formed by a bisecting wall separating the openings. More specifically, at least one bisecting post creates a first opening and a second opening Each of the said first and second openings each have a convexly curved runner, said runner convexly curved along its width; and a concavely curved ceiling, said ceiling concavely curved along its width wherein the center point of the radius of the curved runner varies from the radius of the curved ceiling.

The invention relates to a mold for manufacturing a plastic part, including a first element and a second element forming, in the closed position of the mold, a cavity corresponding to the part to be manufactured, in which the second element includes at least one system for making molding openings in said part, said system including at least one member forming a cavity of an opening for the finished part, said member being movable relative to the second element in the closing direction of the mold, between a retracted position and an position extending into the cavity. The system includes at least one positioning means for positioning the member in the extended position relative to the first element, said system being sized such that, in the extended position of the member, the distance between a surface of the member bearing on the plastic material and the first element enables the formation of a thin layer of plastic material having a repeatable thickness.
