Miles Manufactured Products, Inc.
Large plastic parts. Structural foam gives designers, engineers & manufacturers unique properties and big opportunities. Design assist through production.
Multi-nozzle technology is unique to the structural foam process. Injection nozzles are located throughout the platen surface. This allows large sized parts to have multiple injection locations or the opportunity to run multiple molds simultaneously on a single molding press. Each injection nozzle allows for precisely controlled heat, time and material processing.
Much like typical injection molding, SFM machines use a reciprocating screw and barrel to inject heated plastic into a tool. This however is where the similarities end. The most obvious difference is the size of the machines themselves. SFM machines are massive and so are the parts and opportunities they provide. Unlike injection molding, SFM uses low pressure, gas-assist and other unique methods to mold components up to 200 lbs. in weight.
Structural Foam molding is a way to injection mold large parts. Thermoplastic materials such as HDPE, Polypropylene, ABS and Styrene are used along with a blowing agent which produces a molded article with a cellular core and solid skins. The following is how the process works:
