摘要： PURPOSE:To enable assurance of dimensional precision during the year by calculating an optimum takeout temp. wherein a specified value being an optimum temp. difference for a year is added to the mean value of the atmospheric temp. per day and calculating a cooling time of the inside of a mold necessary to obtain this takeout temp. from a cooling curve which resin material has. CONSTITUTION:The atmospheric temp. To and the surface temp. Tr of a molded form at a time of takeout are measured by the use of a thermocouple. This measured value is stored in a CPU as data. In order to prevent the linear fluctuation in the amount of thermal shrinkage accompanying the fluctuation during the year of the atmospheric temp. To, the optimum temp. difference DELTAT for a year described hereunder may be always held at a specified value: DELTAT=Tr-To. Therefore the temp. Tr of the molded form at a time of takeout is controlled by a formula 1 in correlation with To. Tr is controlled by the cooling time gamma of the inside of a mold. The atmospheric temp. To is always measured but the temp. utilized for control in the mean value To per day obtained from the value measured in the previous day. The temp. Tr of the molded form for To at a time of optimum takeout is calculated from the formula 1. Furthermore the optimum cooling period gamma is calculated from Tr by a formula 2 and control is performed.

摘要： PURPOSE:To obtain the title resin excelling in elongation and tensile strength and improved in impact resistance and abrasion resistance, by adding an additive based on a fluororubber to a liquid crystal polyester resin. CONSTITUTION:The title resin is prepared by adding an additive based on a fluororubber and, optionally, a filler (B) such as carbon fiber, glass fiber or talc to a liquid crystal polyester resin (A). This resin is an injection-moldable resin material used for, e.g., coating the surface of a rotor of an automobile supercharger. By adding a specified amount of additive B to resin A, the title resin increased in elongation and tensile strength and excelling in impact resistance and abrasion resistance can be obtained. In said rotor, scoring or the like occurs very rarely though they occur in a conventional rotor frequently because of rubbing due to an error of assembly, thermal expansion, vibration, etc.

摘要： PURPOSE:To obtain the title resin having excellent flexibility and improved elongation, tensile strength, impact resistance and abrasion resistance, by mixing an olefin elastomer with a mixture of a liquid crystal polyester resin with a Teflon resin. CONSTITUTION:The title resin is prepared by mixing an olefin elastomer (C) with a mixture of a liquid polyester resin (A) with a Teflon resin (B). This resin is an injection-moldable resin material used for, e.g., coating the surface of a rotor of an automobile supercharger, and is one excellent in flexibility and improved in elongation, tensile strength, impact resistance and abrasion resistance. By adding elastomer C to a material formed by mixing resin A with resin B, the title resin decreased in hardness without increasing a resin B content, free from a problem of lowered blendability and improved in low- temperature adhesiveness can be obtained.

CONSTITUTION:After raw materials such as a PVC resin A, a plasticizer B, a stabilizer C, a filler D, a coloring agent E etc., are stirred by means of a high speed mixer 10 and the mixer is ground to prepare a powdered material, this is powdered material is extrusion-molded by a special extruder 11 of a multi-axial type wherein to improve kneading ability, a kneading piece N is provided on a coaxial position of each screw S and a vent hole V for removing a volatile ingredient is provided in a cylinder to prepare a flexible molding made of vinyl chloride. As the kneading piece N is provided on the screw part of the extruder 11, the powdered material is rapidly and thoroughly kneaded and as the generated gas is evacuated from the vent hole V, a flexible vinyl chloride product with good appearance can be molded.

摘要： PURPOSE:To dispense with primer coat application and thereby improve productivity by giving the high-grade appearance of a paint work and inhibiting the generation of pin holes or sink marks. CONSTITUTION:A preliminary molded product 3 is produced by injection-molding a bulk mold company blended with glass fiber using the top force 1 and the bottom force 2 of a molding die, then the top and bottom forces are allowed to become separated from the preliminary molded product 3 to form a void part 4 between the top and bottom forces and the preliminary molded product. At the same time, an in-mold coating material 6 is injected into this void part 4, then the top and bottom forces are closed and the material 6 is molded under pressure and heating to obtain the outside handle of an automobile.
