摘要： PURPOSE:To provide a trimming material for vehicles, which does not cause deterioration even when exposed to the atmosphere over a long period of time, consisting of a polyolefin resin compsn. contg. a specified organonickel compd. weathering and light-resistant agent. CONSTITUTION:0.05-2wt% [2,2'-thiobis (4-t-octyl phenolate)]-n-butylaminenickel of the formula is blended with a polypropylene resin such as a polypropylene/ ethylene copolymer having an ethylene content of 5-20%. The resulting resin compsn. is processed into a trimming material in a conventional manner by subjecting it to stages of molding, degreasing (washing with trichloroethane vapor), masking, primer coating, baking, topcoating and baking, said weathering and light-resistant agent remains in the resin compsn. while scarcely dissolving out of the compsn. during the above degreasing stage, so that a member having excellent resistance to light and weather can be obtd.

摘要： PURPOSE:To prevent the generation of faulty molding upon the rise-up of the starting of molding by a method wherein a cooling water temperature is set at two stages, different depending on the period of stopping a molder and the period of molding, while the cooling water temperature is slowed down upon the rise-up of the starting of molding especially so as not to generate the fluctuation of a mold temperature substantially. CONSTITUTION:A water temperature TL during molding, water temperature TH during stopping the molding and the slow down time (m) of cooling water temperature upon the rise-up of the starting of molding are set previously in a temperature setter accommodated in a setter 29. A micro-computer 30 decides the operating condition of a molder and outputs to a temperature controller 31 in accordance with the result of the decision while handling the above-described set values of water temperature as the target values of temperature control. Especially, the slow-down temperature of the cooling water is operated at every predetermined times upon the rise-up of the starting of molding to make it the target value of cooling water temperature control. The temperature controller 31 effects the feedback control of the condition of a heater 22 through a valve positioner 32 and a heater driving circuit 33 in accordance with a difference between these target values and the measured value of the temperature of cooling water for a mold M, which is measured by a temperature sensor 28, and regulates the opening degree of a servo system mixing type three-way valve 26 or switches a valve circuit for the same valve 26.
