Abstract
PURPOSE: To prepare a synthetic resin product having a cage body around its periphery without a female die and at a low cost by a method wherein an intermediate product smaller than a desired synthetic resin product is prepared in advance and this intermediate product is arranged in the inner part of a cage body to conduct pressure forming.
CONSTITUTION: The intermediate product 1 of thermoplastic synthetic resin having a vassel form smaller than a synthetic resin product to be prepared is manufactured in advance and a support 3 is inserted into the inner part and heated up to a temperture capable of pressure forming. Then, a flange part etc. arranged at the end on the opening side of the intermediate product 1 is pinched by a pincher 4, the cage body 2 is set and the opening part of the cage body 2 is brought into contact with the outer surface of the opening part of the intermediate product 1 and is supported by it. Then, the opening part of a pressure box 5 is set to the opening part of the intermediate product 1, ompressed air is supplied from the pressure box 5 into the inner part of the intermediate product 1 to conduct pressure forming and the intermediate product 1 is expanded until its outer surface comes into contact with the inner surface of the cage body 2 to obtain a desired synthetic resin product.
