10300653 · 2019-05-28 · ·

A method and apparatus is presented. A portion is cut from a thermoplastic sheet of a first thermoplastic material based on a three dimensional model. The portion is secured to a mold. The portion and the mold are heated under vacuum to form a structure. The structure may take the form of a protective covering. In some illustrative examples, the mold may be formed of a second thermoplastic material based on the three dimensional model using additive manufacturing.

METHOD AND DEVICE FOR MAINTAINING AN INNER DIAMETER OF A PLASTIC CONTAINER

Methods and devices for manufacturing plastic preforms and plastic containers are provided. Methods of manufacturing a plastic preform having an inner undercut include forming a preform of plastic in amorphous state and inserting a plug within the mouth of the preform. The plug includes an upper plug member and an expandable element, the expandable element having an initial outer diameter in plan view with the plug in an initial condition and a deployed outer diameter in plan view with the plug in a deployed condition. Methods further include deploying the plug to the deployed condition with the expandable element positioned to engage a side wall proximate the inner undercut and crystallizing the plastic of the preform along the finish portion.

Fiber reinforced thermoplastic sheets for thermoforming

A method of manufacturing a fiber reinforced thermoplastic part includes placing fibers, fixing the fibers in place, cutting the fibers, infusing the fibers with a thermoplastic polymer, stacking multiple sheets of the fibers, and molding the multiple sheets together. A method of manufacturing a part includes placing original fibers, fixing the fibers in place, cutting the fibers, infusing the fibers with a thermoplastic polymer, stacking multiple sheets of the fibers, molding the multiple sheets together to form a moldable sheet, and applying a mold to the moldable sheet.

Material tensioning system

A system and method for forming an item from a material, which may include elongated fibers and/or stretched broken fibers. The material is placed on a first clamping portion, which is placed on a fixture. A second clamping portion is placed against the material and the first clamping portion and secured together, forming a clamping assembly. The clamping assembly is removed from the fixture and placed on a first die portion, having a first profile. A second die portion is also provided, having a second profile. In forming the item, at least one of the first die portion and the second die portion are moved toward each other such that a second surface of the first die portion and a first surface of the second die portion contact and form the material into the item generally replicating the first profile and the second profile.
