摘要： PROBLEM TO BE SOLVED: To provide a production method for a PTFE solid molded article which can uniformly obtain the density and thickness of a curved surface and a complicated shape such as a rib or the like even if a skilled technique is not used and hardly generate a flow mark and crack of a resin.
SOLUTION: In the production method for the PTFE solid molded article, the PTFE molded article with low specific gravity constituted of the PTFE polymer is placed in a mold and pressed at a temperature higher than the meeting point of the PTFE solid molded article to obtain the PTFE solid molded article polymer. The PTFE low specific gravity solid molded article has a specific gravity of 0.3 to 1.8. The PTFE polymer is a tetrafuluoroethylene homopolymer and/or a modified tetrafuluoroethylene.

摘要： A method for bonding and molding modified polytetrafluoroethylene moldings which comprises disposing at least two modified polytetrafluoroethylene preforms having different degrees of thermal shrinkage so that the faces to be bonded are in contact with or close to each other, and baking the preforms to integrally bond them on those surfaces. The bonded parts have a sufficiently high bonding strength even when the molded article has a large wall thickness. Defective moldings are considerably prevented from being yielded, and the dimensional accuracy of the molded articles is heightened. The material loss for the preforms can be reduced. The molding procedure is simple and is effective in greatly improving productivity especially in mass production.

摘要： A method for producing a molded article of a modified polytetrafluoroethylene by joining having the steps of providing at least two premolded parts of modified polytetrafluoroethylenes having different coefficients of thermal shrinkage with allowing their joining faces to be in contact each other or to be closely placed, and sintering the parts to join them at the joining faces. According to this method, the joining faces of parts can be strongly bonded even when the parts have a large thickness. Thus, the production of defective articles is decreased, the dimensional accuracy of a molded article increases, and material loss due to the production of parts by cutting can be decreased. This method improves the productivity, particularly in the mass production, since the joining procedures are simple.
