One of the main challenges associated with the process is to minimize residual stress which directly affects quality and geometric accuracy of injection molded components. Therefore, it is important to select injection molding control variable settings for obtaining the minimum residual stress. Taguchi approach was used to investigate the effect of control variables on residual stresses and to optimize the process. Optimum injection molding variables for machining the polymer were obtained as time for filling 1.5 s, temperature of melt 180°C, temperature of mold 50°C, volume filled 100%, holding time at pressure 15 s, pressure for holding 60 MPa and coolant in temperature 20°C. Analyses of variances and analyses of means methods were used to see which variable has significant effect on the residual stress. The results indicate that pressure for holding, melt temperature and time for filling are the most significant injection molding variables affecting the enticement of residual stress. Regression equation was developed to model the residual stress as a function of the molding process control variables. Keywords: Plastic injection molding, Residual stress analysis, Taguchi methods, Analysis of means, Analysis of variance, Process optimization 1. Introduction The last two decades has seen a speedy growth in the novel applications of injection molding of thermoplastic materials. In the process, polymer in the molten phase is injected into a mold cavity and further shaped under high pressure. Injection molding has several advantages such as quick processing times, simplicity of operation, excellent flexibility, corrosion resistance and capability to produce parts of complex geometric configurations [1]. The injection molding process however has limitations including occurrence of defects such as shrinkage, sink marks and warpage. These defects are caused by variations in temperature and pressure that causes inducement of residual stresses on the part surfaces. Several research studies have been performed worldwide aiming at experimental analysis or numerical simulations to identify the reasons behind injection molding defects. A number of new investigations have emerged, offering significant findings in the area of injection molding [2-9]. The residual stresses in injection molding are caused due to the following: i) thermally induced stress during cooling and ii) viscoelastc flow of the polymer during filling and post filling phases [2]. The geometry of the part is influenced by the injection molding control variables. The holding pressure is found to significantly influence the part geometry as well as the residual stresses induced in it [3]. Furthermore, injection speeds, mold temperature, melt temperature and packing pressure are found to have a direct effect on the residual stresses [4, 5]. The residual stresses on injection mould could be minimized by attaining an effective control over the injection molding process variables. However, because of the complex phenomena of injection molding process and large number of control variables, process optimization still remains as a challenge [6]. One of the approaches to minimize residual stresses was by a selection of optimum wall thickness of the parts, which was attempted in [7]. Tang et al. [8] developed a numerical model for the temperature distribution to calculate thermal residual stresses in the plastic injection molding. They have considered the effect of uneven cooling of the part to obtain thermal residual stresses at various sections of the mold. A hybrid method using advanced soft computing tools involving genetic algorithm and artificial neural network was used to calculate the residual stresses in plastic injection molding at various sections of the part in [9]. The method involved selection of optimum process control variables for the minimum residual stresses on the part represented as a quality indicator of the surface defects as a result of three-

However, the method failed in predicting the residual stress levels at different conditions and instances of injection molding. A similar approach was followed in [10] using global optimization genetic algorithm and back propagation neural network to correlate the responses and the process control variables. Five variables were observed to be dominant in controlling the injection molding process. The variables were packing pressure, packing time, mold temperature, melt temperature and cooling time. 2. Injection molding process control variables In injection molding process, the properties of the thermoplastic material, design of the feeding system and the process control variables determine the inducement of residual stresses in the products. Table 1 shows a summary indicating various defects in the injection molded products. Table 1. A summary of common defects in injection molded products Sl. No. Type of defect Reason for occurrence Possible solutions and recommendations Reference 1 Brittleness Thermal degradation of the melt Increase in injection speed and injection pressure, a decrease in residual stresses in the part [8,11] 2 Warpage and shrinkage Positions of the gates, process settings for the mould Selection of gate positions, orientations and lower residual stress levels [2, 5,7,12,13] 3 Weld lines Insufficient mixing of two streams of molten plastic Enhancement of interface temperature and pressure, venting at such positions [8,11,13] 4 Flash lines Greater injection forces, excess feed, overheating To remove the residual stresses and locked in strains [7,8,11] 5 Material discoloration Melt stagnation, flow over sharp edges Remove excessive residual stress induced by ejection system [5,11-13] The occurrence of defects in injection molding process is primarily due to residual stresses accumulated during the period after the filling. The residual stresses induced in the part are controlled by the injection molding variables, material of the mold and the geometry of the mold [14]. A systematic examination of the results reported in the literature has shown that a number of control variables influence the physics of the injection molding process. Among these control variables, residual stress formation is influenced by number of control variables, see Fig. 1. A statistical approach involving treatment of injection molding process as a multi-objective function was reported in [15] and [16]. The method included analytical hierarchical process, analysis of variance, Taguchi techniques and finite element scheme. Objective functions chosen were warpage, volumetric shrinkage, sink marks, cooling time and residual stresses. However, according to a summary of literature presented in Table 1, residual stress is the dominant objective function and is considered to be an important cause for occurrence of defects. Therefore, in this paper, a single objective optimization of residual stress considering the effect of injection molding control variables is considered. The settings of temperature of melt, temperature of mold, holding pressure, holding time, volume filled and time for filling are selected to obtain the lowest level of residual stress.

The R-sq value of the data is 93%. The p-values in the table show that all the control variables are significant at 95% confidence level. Furthermore, F-value in the table indicates the relative significance of all the control variables. The highest F-value of 624.59 corresponds to the pressure for holding. The next highest F-value of 75.56 corresponds to melt temperature. As seen from Fig. 3, pressure for holding is the most significant variable. Fig. 3. F-value representing the relative significance of control variables The analysis of means plots for residual stresses is presented in Fig. 4. The pressure for holding and melt temperature causes an increase in residual stress. The trend of both variables is a linear increase. As the pressure for holding increases from 60 to 100 MPa, the increase in residual stress is by 55%. Similarly, with an increase in melt temperature, the increase in residual stress is only by 17%. The residual stress has shown a decreasing trend with an increase in time for filling from 1.0 to 1.5 s. While the time for filling is increased further to 2 s, increase in residual stress is not observed. This indicates that for polymers, an adequate amount of filling time is necessary to achieve a uniform flow of the material in order to get the lowest residual stress. As the mold temperature increases from 30 to 50°C, a slight decrease in residual stress is observed. This is also evident from Table 3, with the lowest value of F as 7.72. The residual stress decreases by 7% with an increase in the percentage of volume filled from 92% to 100%. A similar trend and effect on residual stress is observed for the holding time at pressure. The lowest value of 13.76 MPa is obtained corresponding to a coolant in temperature of 20°C.

Among the seven variables considered in this investigation, only three variables are included in representing relationship using the scatter plots. The variables with the highest values of F values are pressure for holding (F=624.59), melt temperature (F=75.56) and time for filling (F =27.06). According to the analysis of variance, test for lack of fit, comparison of R-squared values and analysis of means, representation of the correlation between residual stress (σr) and the control variables is obtained as a general linear regression equation. The equation (1) can be used to predict average residual stress within the area of statistical investigation. σr = 5.14593 - 0.974444 tf (s) + 0.0735926 Tme (°C) - 0.0236111 Tmo (°C) - 0.144444 Vf (%) - 0.0995556 thp (s) + 0.158361 Ph (MPa) - 0.0245556 Tin (°C) (1) where, tf is the time for filling in s, Tme is the temperature of the melt in °C , Tmo is the temperature of the mold °C, Vf is the volume filled in %, thp is the holding time at pressure in s, Ph is the pressure for holding in MPa and Tin is the temperature at the inlet of coolant in °C. a. b.

Conclusions and Future work The paper presents a distinct approach for optimization of injection molding process control variables. The objective function was minimization of residual stress in the process. Based on the investigation and analysis, the following conclusions have been arrived at: Residual stress is considered to be a major factor influencing the development of defects on injection molded components. Injections molding input settings influence the distribution of residual stresses. Due to the complex nature of localized distribution of residual stresses, all the control variables including temperatures, pressures, and time of filling indicate a significant influence. The results of statistical treatment obtained using the general linear model also indicates this effect. The control variables, namely, pressure for holding, melt temperature and time for filling are found to be significant. In order to obtain the optimum operating condition, pressure for holding shows the highest significance with the highest ‘F’ value of 624.59. The pressure for holding and melt temperature causes a linear increase in the mean residual stress of the injection molded component. As the pressure for holding increases from 60 to 100 MPa, the increase in residual stress is by 55%. Similarly, with an increase in melt temperature, the increase in residual stress is only by 17%. A general expression for linear regression between residual stress and the control variables was established for the range of values selected in this investigation. Three dimensional scatter plots for the prevailing three control variables, viz. pressure for holding, melt temperature and time for filling was developed against residual stress. The optimum control variables for the minimum residual stress were obtained for minimum average residual stress: time for filling = 1.5 s, temperature of melt = 180°C, temperature of mold = 50°C, volume filled = 100%, holding time at pressure = 15 s, pressure for holding = 60 MPa and coolant in temperature = 20°C.
