A THERMOFORMING SYSTEM
A thermoforming system has a composite plate, a loading area in which the plate is placed, a heating area in which the plate is heated, a pressing area in which the plate is formed, and at least one mold which is located in the pressing area that applies heat and pressure to the plate so that the plate is formed. The system also includes a thermoforming area which is formed by the loading area, heating area, and the pressing area and consists of at least two different surfaces located opposite each other. A rail system is located on at least one surface in the thermoforming area and allows the plate to be conveyed within the thermoforming area.
Molded cooling and heating face mask
A molded face mask for treating a user's face, the molded face mask having a rigid, inflexible polycaprolactone body molded to the user's face, the body having: i) two opposed, slightly tapered end portions; ii) a generally straight lower edge; and iii) an upper edge having a concave portion disposed approximately half-way along a length of the upper edge. A kit for providing therapeutic relief and reducing redness and bumps associated with facial shaving.
Thermoformable semi-rigid orthoses
An orthosis for supporting a limb or a joint of a human or of a vertebrate animal, including: a sleeve which is at least partly elastic and is designed to enclose a limb or a joint, a plate made of a thermoformable material, and a pocket formed on the sleeve in order to receive the plate, the pocket having a shape adapted to that of the plate. The adherence between the plate and the inner surface of the pocket is treated in order to permit a relative movement of the plate with respect to the material forming the pocket during and after an operation of thermoforming of the plate, this being done by placing the orthosis on the limb or the joint with the plate present in the pocket. This orthosis is designed to be fitted in place and thermoformed by the user himself.
Material forming apparatus using diaphragm and material forming method using diaphragm
A material forming apparatus comprises: a support which is positioned at a side of a forming tool with respect to a material arranged on the forming tool to have a first part covered by the forming tool and a second part separated from the forming tool, and which supports the forming tool; a diaphragm which presses the second part of the material while the outer surface of the expanded diaphragm comes in close contact therewith, in a state in which the first part of the material is compressed by the forming tool and the outer surface of the diaphragm; and a volume-varying member which is disposed near the forming tool between the diaphragm and the support so that at least a portion thereof is positioned on the second part of the material.
THERMOFORMABLE NONWOVEN COMPOSITE
A thermoformable nonwoven composite containing a nonwoven layer which contains a plurality of first staple fibers, a plurality of first binder fibers having a first melting point, and a plurality of second binder fibers having a second melting point, wherein the first staple fibers, first binder fibers, and second binder fibers intertwine and cross at crossover points. The difference first melting point and the second melting point differ by at least about 15° C., and at least 95% by weight of all of the fibers in the nonwoven layer are polyester. The thermoformable nonwoven composite also contains a first resin formulation containing a first resin. The first resin is located within the nonwoven and located in at least a portion of the crossover points. The first staple fibers, the first and second binder fibers, and the first resin all contain a polymer from the same chemical class.
Thermoplastic forming tool
A thermoplastic forming tool includes a wand that includes a handle, a tip, and a conduit coupling the handle to the tip. The tip includes a heating element, a forming shoe, and a forming shoe support. During use, heat from the heating element heats the forming shoe to a temperature at or above the glass transition temperature of a thermoplastic polymer. The thermoplastic forming tool may be used to apply a thermoplastic material to a surface.
Method for hot-forming a thermoplastic material and implementation facility
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.
Mold and method for forming a pressurized fluid chamber
A fluid chamber for a shoe may be formed using pressure channels in a forming mold, eliminating the need to insert a nozzle or needles into the chamber for inflation. A fluid chamber so formed may have a smaller seal area than a chamber formed using an inflation needle, making the chamber more visually pleasing. Apparatus and methods for forming a fluid chamber in this fashion are also disclosed.
VACUUM FORMING MACHINE HAVING PRE-BLOWING LOWER CHAMBER
In a the vacuum forming machine having a pre-blowing lower chamber, a lower space located at the lower side of a raw material which is thermally expanded in a heating process for vacuum forming is sealed and the preset amount of air is introduced into the lower space of the raw material by a blowing device installed to communicate with the sealed lower space of the raw material such that the sagging of the raw material is prevented, whereby the vacuum forming of the raw material whose entire portion is uniformly heated is performed, thereby securing even thickness of the raw material.
VACUUM MEMBRANE THERMOFORMED POLY-4-HYDROXYBUTYRATE MEDICAL IMPLANTS
Methods to produce thermoformed implants comprising poly-4-hydroxybutyrate homopolymer, copolymer, or blend thereof, including surgical meshes, have been developed. These thermoforms are preferably produced from porous substrates of poly-4-hydroxybutyrate homopolymer or copolymer thereof, such as surgical meshes, by vacuum membrane thermoforming. The porous thermoformed implant is formed by placing a porous substrate of poly-4-hydroxybutyrate homopolymer or copolymer thereof over a mold, covering the substrate and mold with a membrane, applying a vacuum to the membrane so that the membrane and substrate are drawn down on the mold and tension is applied to the substrate, and heating the substrate while it is under tension to form the thermoform. The method is particularly useful in forming medical implants of poly-4-hydroxybutyrate and copolymers thereof, including hernia meshes, mastopexy devices, breast reconstruction devices, and implants for plastic surgery, without exposing the resorbable implants to water and without shrinking the porous substrate during molding.
