Abstract

PURPOSE: To produce thick containers on a multi-kind, small-lot production basis with ease at a low cost by reducing the pressure of a femal mold loaded with an intermediate synthetic resin product smaller than the intended one after it is heated up to a specified temperature through a fixing tool inserted thereinto.
CONSTITUTION: An intermediate synthetic resin product 1 smaller in size than the intended one is made by the injection method employing a thermoplastic resin such as polymethyl acrylate and polystylene. With a fixing tool 2 inserted into the intermediate product, the product is heated with a heating body 3 at a temperature above the thermal deformation point but below the decomposition point. Then, a splitable female die 4 is provided. After the mouth section of the intermediate pro- duct 1 is closed with a sealing member 5, a compressed air is jetted on the inner surface of the intermediate product 1 via an air hole 2a to press the inner surface 4b to mold. Then, the unnecessary portion close to the grasping section 4a of the female die 4 is cut away to obtain a synthetic resin product.
