Object stage and hot pressing apparatus
An object stage and a hot pressing apparatus are disclosed. The object stage includes a base (1) and a support device (2) fixed on the base (1), wherein the support device (2) includes a plurality of detachable support sub-devices (21); the support device is configured to allow a printed circuit board (3) with at least one protruding structure (4) to be placed thereon, and no support sub-device (21) is disposed at a position on the support device (2) corresponding to the protruding structure (1). The object stage reduces manufacture cost, saves production time and improves production efficiency.
Sheet manufacturing apparatus
A sheet manufacturing apparatus includes an impeller mill defibrating, in a dry process, a raw material containing a fiber, a mixer mixing a defibrated material and a resin, using an air stream to produce a mixture of the defibrated material and the resin, a sieve having an opening through which the mixture passes, a belt, a heater, and a nozzle. The mixture is accumulated on an upper side of the belt to form a web. The heater heats the web to form a sheet so that the fiber is bonded by the resin. The nozzle is arranged between the belt and the heater and applies a liquid to a partial portion of the web so that bonding between the fiber and the resin in a first portion of the sheet is weaker than bonding between the fiber and the resin in a second portion of the sheet.

Device for moulding a plastic component having at least one undercut
A device for molding a plastic component having at least one undercut is disclosed herein. The device including; a fixed block and a mobile block, the fixed block and the mobile block joining along a joining plane and defining first and second cavities defining a molding cavity to receive the plastic, the molding cavity having a first volume and a main direction of demolding; means of separating the mobile block from the fixed block; at least one mobile insert placed in the fixed block; thrusting means urging the mobile insert toward the mobile block; means for moving the at least one mobile element in a secondary direction not parallel to the main direction of demolding.
FOAMING AND SHAPING PROCESS FOR A THERMOPLASTIC SHEET, AND ASSOCIATED APPARATUS AND SHAPED FOAMED THERMOPLASTIC SHEET
A method of foaming and shaping a thermoplastic sheet comprising a poly(phenylene ether), a polyetherimide, or a combination thereof includes foaming the thermoplastic sheet with supercritical carbon dioxide to form a foamed thermoplastic sheet, and shaping the foamed thermoplastic sheet to form a shaped foamed thermoplastic sheet. The shaping step includes compressing the foamed thermoplastic sheet between a first metal plate and a secondi metal plate, each of which has a grooved surface facing the thermoplastic sheet. The first metal plate and the second metal plate are connected by a flexible, compressible linkage capable. When the flexible, compressible linkage is in its uncompressed state, only the second (lower) metal plate is in contact with the shaped foamed thermoplastic sheet. When the flexible, compressible linkage is in its compressed state, both the first (upper) and second (lower) metal plates are in contact with the shaped foamed thermoplastic sheet.
CUSHION MATERIAL FOR HOT PRESSING
A cushion material 10 for hot pressing includes a cushion part 1. The cushion part 1 includes a woven fabric 5, in which a twisted yarn is used for at least one of warp 5a or weft 5b, and a polymer material 6 adhered to a surface of a fiber forming the woven fabric 5. The twisted yarn used for at least one of the warp 5a or the weft 5b of the woven fabric 5 is formed by twisting a plurality of texturized yarns made of glass fiber.
ELECTRONIC GLOVE FOR MAKING A THREE DIMENSIONAL STRUCTURE
The present invention provides an electronic glove device for making three-dimensional structure. The device includes a heating unit, multiple pressure sensors and a microcomputer unit. The heating unit includes a first thermally conductive layer and a thermally insulated layer, and multiple electric heaters and temperature sensors are located between the first thermally conductive layer and the thermally insulated layer. The microcomputer unit is connected to the temperature sensors and the pressure sensors. Once pressure is exerted on thermoplastic plastic through the heating unit by hands, the microcomputer unit is configured to receive the increase of the pressure from the pressure sensors, and to direct the heating unit to increase the temperature of the first thermally conductive layer in accordance with the magnitude of the increase of the pressure. Use of the electronic glove, in combination with thermoplastic plastic, enables users to manually make three-dimensional structures easily and quickly.
Reinforced press base, strengthening ring, and method of reinforcing a press base
Embodiments of the present invention include a press base assembly, a strengthening ring for use with press bases and related methods. In one embodiment, a press base assembly includes a press base having a body that includes a piston cavity at one end. The body, at a second end opposite that of the piston cavity, may exhibit a desired geometry. A strengthening ring may be shaped, sized and configured to substantially mate with the geometry of the second end of the body and be placed thereover. For example, the geometry of the second end may be substantially circular exhibiting a particular diameter and circumference. The strengthening ring may have substantially circular internal surface sized and configured such that the strengthening ring is positioned on the second end of the body in a manner that results in an interference fit between the two components.
METHOD FOR PRODUCING MOLDED BODY
A method for producing a molded body is provided. The molded body is made of a thermoplastic material and can be produced in a short molding cycle. The method includes a step of compressing a molding precursor including a thermoplastic resin between a pair of molding dies having an insulation site at a surface that comes into contact with the molding precursor, in order to obtain a molded body. The temperature T.sub.A of the molding precursor at the start of compression satisfies the following Formula 1: E(100)0.04<E (T.sub.A)<E(100)0.13. The temperature T.sub.B of the pair of molding dies at the start of compression satisfies the following Formula 2: E(100)0.3<E(T.sub.B)<E(100)0.7. The insulation site has a heat conduction coefficient of 5 W/(m.Math.K) or less, and the surface that comes into contact with the molding precursor has a dynamic friction coefficient of 0.25 or less.
