Abstract: A foaming and forming method for soft and hard types poly products that includes blending soft or hard type poly material (expanding resin) with selected proportion of additives of carbonic calcium powder, 2-heptanone, soda powder, water, starch power and phosphoric acid-3 to form an evenly blended product solution, injecting the blended product solution into a silicon or steel mold for rapidly generating required air bubbles (beehive shapes) to expand the product solution a number of times, hardening the product solution to form a semi-finished product to be released from the mold immediately, and performing colored painting and embellishment for the semi-finished product to form a light weight and easy to transport poly product.
