WebBlow molding is a manufacturing process that involves turning plastic material into a hollow plastic component. The first step is melting and extruding plastic pellets into a tube (i.e., parison). The tube is then enclosed within a pre-formed mold. Next, air is blown into the contained tube to force the material to conform to the shape of the mold. WebMelt Flow Rate (MFR) Often a moulder has to change material grades. One of the first properties to be consulted on the new data sheet is usually the MFR. This is to establish …
