FOAM MOLDING: Presentation: Definition: "Any polymer process that provides a partially or fully foamed product." (Scientific Dictionary) Foam molding is a manufacturing process that creates product and product parts made of foam. The foam molding process involves mixing the foaming agent and base resin into molten polymer, creating a mixture that will be injected into a mold, which will solidify and become a part or object. History: In 1872 American inventors John Wesley Hyatt and his brother Isaiah Hyatt patented the very first injection molding machine. The machine was relatively simple compared to modern technology. The way the machine worked was like a large hypodermic needle, a plunger-like device was used to inject plastic through a heated cylinder into a mold. The machine could produce everyday items such as buttons and splints. The industry slowly progressed over the years and expanded greatly in the 1940s during the post-World War II economic expansion that created massive demand for inexpensive, mass-produced products. Later, American inventor James Watson Hendry created the first screw injection machine in 1946, with screw injection; the machine was much more precise in terms of injection speed and also allowed the improvement of the quality of the articles produced. The advantage of this machine was also the fact that the materials could be mixed before injection, which made the task easier. Finally, in the 1970s, James Watson Hendry began to develop the first gas-assisted injection molding process (figure 1), this new invention allowed the production of more complex products such as hollow objects that cooled rapidly. This process has been significantly improved for...... middle of paper ......The UK's leading plastics trade association. http://www.bpf.co.uk/Plastipedia/Processes/Structural_Foam.aspxInjection Molding 2014 http://en.wikipedia.org/wiki/Injection_moldinghttp://polycel.com/why.html x http:// thesciencedictionary .org/foam-moulding/Structural Foam Molding 2014 https://www.efunda.com/processes/plastic_molding/molding_structuralfoam.cfmInjection Molding 2014 https://www.efunda.com/processes/plastic_molding/molding_injection.cfm Uniloy Milacron Structural foam molding guide http://www.uniloyna.com/images/pdf/SFmolding_guide.pdf Port erie plastics 2013 http://www.porterie.com/plastic-processing-structural-foam-blow-molding -extrusion.html Foam Flexible Injection Molding Sluzer Chemtech ltd Markus Scheuber 20042014 Solid Concepts Inchttp://www.solidconcepts.com/resources/design-guidelines/injection-molding-design-guidelines/
