There has been evidence found suggesting that Egyptians and Babylonians blew plastic materials, but Ferngren and William Kopitke were the first verified people who used the Blow Molding Process. PLASTIC MOLD The process principle comes from the idea of blowing glass. Ferngren and Kopitke produced a blow molding machine and sold it to Hartford Empire Company in 1937. PET preform manufacturers in india This was the beginning of the commercial blow molding process. During the 1940s the variety and amount of products were still very limited and therefore blow molding did not take off until later. Once the variety and production rates went up the amount of products created followed soon there after. In the United States soft drink industry the amount of Plastic Mold containers went from zero in 1977 to ten Billion in 1999. Today even a greater amount of products are blown and it is expected to keep increasing.
PET plastic mold, For amorphous metals, also known as bulk metallic glasses (BMGs), blow molding has been recently demonstrated under pressures and temperatures comparable to Plastic Blow Molding. This technique allows molding BMGs with an about 50 times higher strength than plastics into shapes that were previously not achievable with crystalline metals.
