MOLD DESIGN
Key to the injection-molding process,the injection mold forms the molten plastic into the desired shape, provides the surface texture, and determines the dimensions of the finished molded article. In facilitating mold-cavity filling and cooling, the mold also influences the molding cycle and efficiency as well as the internal stress levels and end-use perfo......Read more

MFA and MFV
Definition Here we present two simple yet important design and process parameters: melt-front velocity (MFV) and melt-front area (MFA). As its name suggests, melt-front velocity is the melt-front advancement speed. Melt-front area is defined as the cross-sectional area of the advancing melt front: either the length of the melt front multiplied by the thickn......Read more

Filling pattern
What is the filling pattern? The filling pattern is the transient progression of the melt front within the delivery system and mold cavities. It plays an important role in determining the quality of the part. Melt front velocity influences filling pattern Constant MFV The ideal filling pattern has melt reaching every extremity of the cavity simultaneously, ......Read more

Equations
Based on a simplification of classic fluid mechanics theory, the injection pressure required to fill the delivery system (the sprue, runner, and gate) and cavities can be correlated with several relevant material, design, and processing parameters. In the following equations, P is the injection pressure and n is a material constant (the power-law coefficien......Read more

Injection pressure
Pressure drives the melt Pressure is the driving force that overcomes the resistance of polymer melt (see Pressure-driven flow), pushing the polymer to fill and pack the mold cavity. If you place a number of pressure sensors along the flow path of the polymer melt, the pressure distribution in the polymer melt can be obtained, as schematically illustrated ......Read more
