PROCESS FOR MANUFACTURING A LIGHTWEIGHT RETRACTABLE SHOWER DOOR ENCLOSURE AND A LIGHTWEIGHT SHOWER DOOR ENCLOSURE MANUFACTURED THEREBY
20250107671 · 2025-04-03 ·

A method of manufacturing a lightweight, plastic shower door enclosure for enclosing a shower in a limited space environment includes providing a supply of a plastic polymer material for each part of the shower door enclosure to be manufactured, feeding the plastic polymer material to a rotating screw arranged within and along a central axis of a barrel feeder, controlling a rotation of the rotating screw to mix the plastic polymer material while compelling the mixed, plastic raw material forward through a heated portion of the barrel, ejecting the mixed, heated, plastic polymer material through an adapter and/or die as an extrudate supply for forming the each part and cutting the extrudate to the dimensions of the each part of the shower door enclosure.

Method of manufacturing electrical cable, and resulting product, with reduced required installation pulling force

Disclosed are cable types, including a type THHN cable, the cable types having a reduced surface coefficient of friction, and the method of manufacture thereof, in which the central conductor core and insulating layer are surrounded by a material containing nylon or thermosetting resin. A silicone based pulling lubricant for said cable, or alternatively, erucamide or stearyl erucamide for small cable gauge wire, is incorporated, by alternate methods, with the resin material from which the outer sheath is extruded, and is effective to reduce the required pulling force between the formed cable and a conduit during installation.

Method for continuously manufacturing UHMWPE products

The present invention relates to a method for continuously manufacturing UHMWPE products comprising:providing a counter-rotating twin-screw extruder;feeding UHMWPE powder into a hopper of said counter-rotating twin-screw extruder;transporting said UHMWPE powder from said hopper through said counter-rotating twin-screw extruder to an outlet of said counter-rotating twin-screw extruder;further transporting said UHMWPE powder from said outlet of said counter-rotating twin-screw extruder to an entrance of a heat-controlled tooling system for defining the shape of UHMWPE products;withdrawing said UHMWPE products from an outlet of said heat-controlled tooling system.

METHOD FOR PRODUCING POLYTETRAFLUOROETHYLENE (PTFE) THORIUM OXIDE MEMBRANE
20260055257 · 2026-02-26 ·

The present disclosure relates to a method 200 for producing polytetrafluoroethylene (PTFE) thorium oxide membrane. The method 200 comprising combining metal oxide and polytetrafluoroethylene (PTFE) powder to form a first mixture and screening the first mixture to remove aggregates. The method 200 also comprising mixing a lubricant, wetting agent, and optional pigments to form a second mixture and spraying the second mixture over the first mixture. The method 200 also comprising compacting the homogeneous product into a preform and extruding and calendaring the preform to obtain a tape of desired thickness. The method 200 also comprising heating the tape formed to evaporate the lubricant and sintering the tape to fuse polytetrafluoroethylene (PTFE) and encapsulate the thorium oxide particles. The method 200 also comprising cooling the sintered tape at a controlled rate to prevent crack formation and maintain the integrity of the membrane structure.
