摘要： Methods of forming dental appliances. The methods may include partially curing a prepolymer mixture in a first mold to form a partially cured polymer mixture. The first mold may have an internal cavity that is shaped to provide the partially cured polymer mixture with a first shape having a channel in accordance with a dental arch. The first shape may have a greater thickness at locations corresponding to where a gingival line of the dental appliance will be formed compared to a thickness at occlusal surfaces of the dental appliance. The methods may include modifying the first shape of the partially cured polymer mixture to form a shell having cavities shaped to receive teeth. The methods may also include fully curing the shell by exposing the partially cured polymer mixture to energy until the partially cured polymer mixture thermosets.

摘要： A forming apparatus for forming objects by forming a sheet of thermoformable material includes a thermal conditioning station including a kiln for heating the material to an operating temperature, and a heating station positioned downstream of the thermal conditioning station and including a heating device to heat set portions of the material to a temperature near a softening temperature of the material. In order to reduce reject material at the restart of the apparatus following machine downtime, the kiln and the heating device are positioned near one another in such a manner that a part of the material interposed between the thermal conditioning station and the heating station is heated by the heat generated by a kiln and/or by the heating device.

摘要： An improved process for forming a PTFE mat is described. The process includes providing a dispersion with PTFE, a fiberizing polymer and a solvent wherein said dispersion has a viscosity of at least 50,000 cP. An apparatus is provided which comprises a charge source and a target a distance from the charge source. A voltage source is provided which creates a first charge at the charge source and an opposing charge at the target. The dispersion is electrostatically charged by contact with the charge source. The electrostatically charged dispersion is collected on the target to form a mat precursor which is heated to remove the solvent and the fiberizing polymer thereby forming the PTFE mat.

摘要： A process for forming a moldable, uncured nonwoven composite containing forming a structural nonwoven layer, at least partially impregnating the structural nonwoven layer with an uncured, water-based thermosetting resin having a cure temperature of at least about 160° C., and at least partially drying the uncured, wet nonwoven composite. The structural nonwoven layer contains a plurality of binder fibers and a plurality of reinforcing fibers which are cellulosic fibers. Heat and pressure are applied to the moldable, uncured composite to a temperature of at least about 160° C. at least partially melting the binder fibers, curing the water-based thermosetting resin, and bonding at least a portion of the reinforcing fibers to other reinforcing fibers forming the molded, cured composite. The reinforcing fibers react with and form covalent bonds with the thermosetting resin.

摘要： Assisted magnetic forming uses a magnetic field to assist in the forming or molding of metallic and non-metallic materials. For example, such a forming process may form a blank of ferromagnetic metals like high-strength steel and high-hard armor, non-ferromagnetic metals like aluminum and magnesium, as well as non-metals like ceramics, plastics, and fiber-reinforced composites into formed or molded parts. The magnetic field is generated to partially or completely saturate the blank during the forming process, which increases the blank's formability and/or moldability while in the presence of the magnetic field.

摘要： A method for shaping a preform made from thermoplastic material, and a facility for implementing the method, comprising the following steps: a) providing a preform made from thermoplastic material having a surface; b) supplying thermal energy to the preform by radiation in such a way as to make it ductile; and c) shaping the ductile preform inside a forming mould. Step b) further involves simultaneously spraying a gaseous fluid onto the surface of the preform in order to preserve the surface.
