Injection Molding and Parameters

Many process parameters, such as the melting temperature, mold temperature, injection pressure, injection 

The molding parameters have a great influence on part quality after the thermo-mechanical properties of mold material [45]. An unsuitable process parameter setting can cause many product defects (e.g., a long lead time, a large amount of scrap material, etc.) and unstable product quality during the injection molding process. 

Processing parameters have to be set according to the mold cavity design and its size, materials properties, and the quality of molded product without defects. Parameters are a focus since an optimal processing parameter design could help to solve most quality control problems. 

For materials with higher melting temperature, the design and process changes need to be considered. Melt temperature settings reflect the material degradation and are important to achieve the best molded part quality. 

The barrel of the injection molding machine supports the reciprocating plasticizing screw. It is heated by the electric heater bands. Increasing heat profile across the barrel may not be the most appropriate profile for all parts. It depends on the size of product and mold the heat profile may be a reverse, hump, or flat profile. Some adjustments may be necessary to obtain the optimum process conditions and part quality.
