Abstract In this work, the impact of good manufacturing practices (GMP) on specific energy consumption (SEC) plastic injection molding process, in 9 representative companies Colombia, was studied. The GMP applied to process and degree which they are adopted by were defined. Afterwards, SEC 17 processes those evaluated. Finally, applying their effect application analyzed ranges from 35 72%. A si...

Currently, the use of plastic products is increasing in various fields, due to their flexibility and low production costs. The injection molding process a technique that often used formation products. focus problem this study effect heating temperature hydraulic pressure on results box gear molds using process. test method uses variations produce maximum mold shape gear. From for full yield wit...

The electrically conductive polymers currently used cannot be industrially processed like plastics. Here, we reported a strategy of producing polymer composition with tin-gallium semi-liquid alloy for plastic molding to produce parts metallic conductivity (>106 S m−1). Molecular modeling and rheological experiments demonstrated that the key successful processing was viscosity matching between m...

Plastic injection molding is a widely used manufacturing method in the automotive and machinery sectors. The design manufacture of appropriate mold needed to plastic product with this are difficult, time-consuming, costly process. Due developing technology increasing quality requirements, remains insufficient, especially for sensitive intricate parts that will be manufactured low numbers. In ad...

In this study, injection velocity in injection molding process was analyzed. Since physical behavior of thermoplastic and environmental condition in injection machine such as high temperature and pressure make a complex dynamics in injection molding system, the injection velocity is consequently difficult to control by some classical control methods. Hence, robust and adaptive control (Fuzzy Sl...

Metal powder injection molding is a shaping technology that has achieved solid scientific underpinnings. It is from this science base that recent progress has occurred in titanium powder injection molding. Much of the progress awaited development of the required particles with specific characteristics of particle size, particle shape, and purity. The production of titanium components by injecti...
