This paper presents the development of a new polymer matrix composite (PMC) feedstock material by the injection molding machine. The material consists of iron powder filled in an acrylonitrile butadiene styrene (ABS) and surfactant powder (binder) material. In this study, the effect of powder loading and binder content on the mechanical properties was investigated experimentally. The detailed formulations of compounding ratio by Brabender Mixer and injection molding machine of the sample specimen was used with various combinations of the new PMC material. Based on the result obtained, it was found that, higher powder loading of iron filler affected the hardness, tensile and flexural strength of PMC material. With 32% iron powder loading in ABS composites increase the flexural force, maximum stress and force of PMC material through an injection molding process.

This paper presents the development of a new Copper-ABS feedstock material by the injection molding machine. The material consists of copper powder filled in an acrylonitrile butadiene styrene (ABS) binder and surfactant material. In this study, the effect of metal filled ABS and binder content on the contact angle and surface tension was investigated experimentally. The detailed formulations of compounding ratio with various combinations of a new Copper-ABS feedstock was done by volume percentage (vol. %). Based on the result obtained, an increment by vol. % of copper filler in ABS effected on contact angle and surface tension results. With highly filled copper content in ABS composites increase the surface tension value. It can be observed that, the tendency of the liquid surface that allow to resist an external force in PMC material through an injection molding process.

The plastic injection molding is widely used for the manufacturing of complicated-shaped and high value-added products. The plastic injection molding machine is the most important equipment for the industry. This paper focuses on the mold separation (MS) of the injection molding machines. The characteristics of the MS of injection molding machine with different clamping units are systemically analyzed, the five-hinge joint-double toggle clamping unit and the direct hydraulic pressure clamping unit included. The study points out there are several typical differences between the different clamping units. Meanwhile, it shows there is a linear relation between the MS value and the product weight, and explains why the MS signal can be used to control the injection molding process.

This paper presents the development of a new polymer matrix composite (PMC) material for use in injection molding machine. The material consists of iron powder filled in an acrylonitrile butadiene styrene (ABS) and surfactant powder material. In this study, the effect of iron powder was investigated as a filler material in polymer matrix composite and ABS was chosen as a matrix material. The detailed formulations of compounding ratio by volume percentage (vol. %) with various combinations of the new PMC are investigated experimentally. Based on the result obtained, it was found that, vol. % increment of iron filler effected on the hardness, tensile and flexural strength. With highly filled iron content in ABS composites increase the hardness and tensile strength of PMC material through an injection molding process.

Good control of plastic melt temperature for injection molding is very important in reducing operator setup time, ensuring product quality, and preventing thermal degradation of the melt. The controllability and set points of barrel temperature also depend on the precise monitoring and control of plastic melt temperature. Motivated by the practical temperature control of injection molding, this paper proposes MPC and IMC based control scheme. A robust system identification and control methodology is developed which uses canonical varieties analysis for identification and model predictive control for regulation. The injection molding process consists of three zones and the mathematical model for each of the zone is different. The control output for each zone controller is assigned a weight based on the computed probability of each model and the resulting action is the weighted average of the control moves of the individual zone controllers. Keywords: Injection-Molding Machine (IMM), IMC Control, Temperature Control.

Injection molding is one of the major manufacturing processes for thermoplastic polymers. In injection molding machine, process variables play a very important role in generating defects in products. In the present paper manufacturing of ball point pen is taken up to investigate the prevention of defects through design and controlling various process parameters. Two molds are designed and fabricated specially for this experimental work. The analysis showed that the defect occurrence has close relation with pressure, speed and the temperature of the injection molding machine in addition to the basic design of the mold. The paper suggests preventive actions for the defects like flash, burn marks, short shot, shrinkage, weld line, warpage and sink mark. The preventive actions were successfully implemented in manufacturing the ball point pen.

Composite Fabrics

The purpose of this paper is to study the effect of high temperature in injection molding process on mechanical properties of the warp-knitted and nonwoven composite fabrics (WNC)used in car interior. Tensile, tearing and peeling properties of WNC fabrics were tested after heat treatment under120, 140,160,180°C respectively. It was found that, after 140°C heat treatment, the breaking and tearing value of these WNC fabrics are lower than others. The results of this study show that this phenomenon is due to the material properties of fabrics. These high temperatures have no much effect on peeling properties of these WNC fabrics. It is concluded that in order to preserve the mechanical properties of these WNC fabrics, the temperature near 140°C should be avoided possibly during injection molding process.
