摘要：The manufacturing method of foam plastic product, in the method, such as byusing the foaming agent added in the fabrication process, stratiform discontinuity (2) aregenerated in product (1), such as pre- bubble, to be steeped thoroughly to film-formplastic products (1). Product (1) is pressurizeed with required gas (such as nitrogen or air)at a positive pressure, makes gas diffusion into product. Then product (1) is inflated, isheat-treated it under reduced pressure, in this process, product heats at a temperaturelower than its melting point.
