Microplastic injection? Identification and quantification of plastic particles in medical injections
Science of The Total EnvironmentMicroplastics (MPs) mainly enter the human body through ingestion and breathing. Most of them are excreted through feces, and only a small amount can accumulate in human organs and tissues. In contrast, if intravenous injection contains MPs, it could directly enter bloodstream and maybe pose severe health risk.

Modeling of Plasticating Injection Molding – Experimental Assessment
International Polymer Processing, 2014Abstract A computational model for the description of polymer flow during the plasticating phase of the injection molding process is proposed. The polymer behavior is determined during the dynamic and static phases of the process. The model takes into account the backwards movement of the screw, the presence of a non-return valve and ...

The plasticating process in injection molding
Polymer Engineering & Science, 1974AbstractA mathematical representation of the plasticating process in a reciprocating‐screw injection‐molding machine has been formulated as a design tool for simulating the effect of processing parameters on the melting performance, the melt temperature, and the pressure profile.

Multiobjective optimization of a plastic injection molding process
IEEE Transactions on Control Systems Technology, 1994It is well known that the PID regulator has been very successful and widely accepted for controlling industrial systems where one objective function is the performance criterion. The question is whether the same success can be achieved for more than one objective function using the basic PID controller, while preserving its simplicity for use by an ...

Product quality prognosis in plastic injection moulding
Production Engineering, 2010Plastic injection moulding is a typical complex manufacturing process. Its product quality is difficult to assure because of the nonuniform material shrinkage. This research introduces a prognostic concept for predicting the product quality (four edge shrinkages).

Spiral and conformal cooling in plastic injection molding
Computer-Aided Design, 2015Designing cooling channels for the thermoplastic injection process is a very important step in mold design. A conformal cooling channel can significantly improve the efficiency and the quality of production in plastic injection molding. This paper introduces an approach to generate spiral channels for conformal cooling. The cooling channels designed by
