Provided is a sheet-type molded body that is formed by sewing a sheet, wherein thread is used for at least part of said sewing, the thread being composed of a resin composition for thread containing resin for thread, the thread having a melting point of no more than 200? C., and a laminate comprising: the sheet-type molded body; and a polyurethane foam formed body, the sheet-type molded body, and the laminate comprising: the sheet-type molded body; and a polyurethane foam layer being able to be produced by a simple method at low cost without damaging design qualities over time, and making it possible to prevent leakage of raw material etc. from sewed portions when backed with the polyurethane foam layer.

Provided is a vinyl chloride resin composition that is capable of forming a vinyl chloride resin molded product having excellent fogging resistance. The vinyl chloride resin composition contains a vinyl chloride resin, a polyester plasticizer, and a polyalkylene glycol. The vinyl chloride resin composition is preferably used in powder molding.

Provided is a method in which a computational device generates a design of a negative mold of teeth. The negative mold of the teeth is fabricated from the design of the negative mold. An aligner is formed using the fabricated negative mold. Provided also is a negative mold of teeth for fabricating a positive model of the teeth for an aligner. The negative mold comprises a tooth surface, and an identity tracking entity coupled to the tooth surface to provide identification.

There are provided a powder slush molding machine that preheats a mold using the transfer time of the mold and may be reduced in size, and a powder slush molding method using the powder slush molding machine.

There are provided a powder slush molding machine and a powder slush molding method using the powder slush molding machine. The powder slush molding machine includes: a mold heating portion that heats a mold so that the temperature of the mold is set to a value equal to or higher than a predetermined temperature; a powder slush portion that sprays a molding resin, while powdering the molding resin, to mold a sheet-like material having a predetermined thickness on the inner surface of the heated mold; a mold cooling portion that cools the mold so that the temperature of the mold is equal to or lower than a predetermined temperature; a mold working portion that separates the cooled sheet-like material from the mold; and a transport device that moves the mold between the respective portions. A preheating device for heating the mold is provided at a part of the transport device.
