PURPOSE:To provide a reactive injection molding method and a manufacture of a transmission type screen which are able to efficiently effect the temperature up of a mold frame in a short period of time, and correctly readily perform the control of reactive temperature, wherein moreover, the workability is excellent. CONSTITUTION:Raw material resin liquid is injected by the use of a form 4 having two opposite mold surfaces and in used of previously heated hot buffer plates 6, 7, the aforegoing form 4 is contact-held for reaction-solidifying it, and then taking a molded article out of the form in order to obtain a transmission type screen. By the use of the hot buffer plates, the form can be made thin and the time to the start of reaction can be conducted in a short period of time, furthermore, since the hot buffer plates act to absorb the generation of heat due to polymerization heat, the reactive temperature is controlled easily. |
