A method for manufacturing a rotor blade component of a rotor blade includes feeding a flat sheet of material into a thermoforming system, wherein the material comprises at least one of a thermoplastic or thermoset material. The method also includes heating the flat sheet of material via the thermoforming system. Further, the method includes shaping the heated flat sheet of material via at least one roller of the thermoforming system into a desired curved shape. Moreover, the method includes dispensing the shaped sheet of material from the thermoforming system. In addition, the method includes cooling the shaped sheet of material to form the rotor blade component.

Improved separator film compositions, methods and systems for use in producing thermoformed dental appliances are disclosed.

A molding method of crystalline plastics includes: providing a raw material; executing a thermoforming step; executing a cooling crystallization step; and executing a cooling and demolding step to form a crystalline plastic product, and a staged cooling technology is used to achieve the effect of simultaneously performing the cooling crystallization step and the cooling and demolding step in a mold. The molding method does not require an expensive cooling system, nor require an additional crystallizer, and the method can improve the process yield, lower the required equipment and labor costs and expenses, and reduce the total process time significantly.

Provided is a method of making a three-dimensional object, which method may include the steps of: (a) producing an intermediate object (21) from a dual cure polymerizable liquid by additive manufacturing, the intermediate object having the shape of the three-dimensional object in warped or distorted form; (b) optionally washing the intermediate object; then (c) contacting the intermediate to a form (22), which form has a shape corresponding to the three-dimensional object, and with the intermediate conformed to the shape of the form; then (d) further curing the intermediate object in contact with the form to produce the three-dimensional object (24) under conditions in which the three-dimensional object retains a shape conformed to the form after separating therefrom; and then (e) separating the three-dimensional object from the form.

The present invention related to an apparatus and method for the manufacturing of beverage capsules. The apparatus can preheat the material used to form the beverage material during the manufacturing process. The material and apparatus are particularly suitable for use in producing single serve beverage capsules from biodegradable materials.

A forming system includes a trim blade 7 for cutting off a sheet material 2 provided between a lower die 60 and an upper die 66, a first lower plate 81 provided outside a first lower die end 60a in a side view of the lower die 60, and a first upper plate 85 provided outside an upper die end 66a, configured to reciprocatively move together with the upper die 66 and extending toward the first lower plate 81. A cut plane of the blade 7 intersects a first excess edge portion 25 which is a portion of the sheet material 2 outside the lower die end 60a, and at least a portion of the excess edge portion 25 is sandwiched between the first lower plate 81 and the first upper plate 85 in a state in which the lower die 60 and the upper die 66 are clamped.

A machine for manufacturing a mask includes a plurality of carriers mounted to a belt so as and having a plurality of molding cavity inserts. A feed station supplies material from a roll so as to form a sheet of material on to the carriers. A shell forming station is configured to press a molding core inserts into the molding cavity inserts so as to form a shape of the mask. A welding station generates a predetermined ultrasonic vibration at a predetermined frequency and a predetermined amplitude so as to weld the sheet of material. A cutting station cuts out the mask from the sheet of material. A mask grabbing apparatus is configured to grab the mask and position the mask for retrieval.

A strip-shape softened resin sheet (S) which is continuously extruded from a molten resin extruder is cut to a unit resin sheet and a press molded product is manufactured by press-molding the unit resin sheet in a press-molding machine. Prior to cutting the continuously extruded strip-shape softened resin sheet (S) to the unit resin sheet (U) , the slits C.sub.1, C.sub.2, C.sub.3, C.sub.4 and C.sub.5 which promote the molding to the press molded part from the unit resin sheet (U) (improve an inflow property of the material) are formed by a cutter which is upwardly and downwardly driven by an air cylinder at a portion P.sub.3 in which the material therein is out of a range of the press molded products P.sub.1 and P.sub.2 obtained by press-molding the press molded product by using the press molding machine and becomes a scrap. The inflow property of the resin material for vertical walls and embossment portions when press-molding is improved and the defects of the product can be prevented.

A strip-shape softened resin sheet (S) which is continuously extruded from a molten resin extruder is cut to a unit resin sheet and a press molded product is manufactured by press-molding the unit resin sheet in a press-molding machine 20. Prior to press-molding the unit resin sheet (U) by the press-molding machine, the unit resin sheet (U) is heated by a heating machine 16. The heating machine 16 comprises a first heating furnace 84 and a second heating furnace 86. The first heating furnace 84 includes a series of heaters 84-3 and 84-4 whose heat source is infrared ray in a far-infrared region and the second heating furnace 86 includes a series of heaters 86-3 and 86-4 whose heat source is the infrared ray in a middle-infrared region. In the first furnace 84, the unit resin sheet (U) is continuously conveyed with a low velocity and is gradually heated by the far-infrared ray up to temperature which is slightly lower than the temperature which is suitable for press-molding the unit resin sheet (U). In the second furnace 86, the unit resin sheet (U) is stopped and is rapidly heated by the middle-infrared ray. By efficiently heating the unit resin sheet (U), a cycle time can be shortened and the production speed can be improved.
