    The plastic injection moulding process produces large numbers of parts of high quality with great accuracy and quickly. It has widely used for production of plastic part with various shapes and geometries. Side arm is one of the product using injection moulding to manufacture it. However, there are some difficulties in adjusting the parameter variables which are mould temperature, melt temperature, packing pressure, packing time and cooling time as there are warpage happen at the tip part of side arm. Therefore, the work reported herein is about minimizing warpage on side arm product by optimizing the process parameter using Response Surface Methodology (RSM) and with additional artificial intelligence (AI) method which is Genetic Algorithm (GA).

    Crash box is a vital component for a vehicle in absorbing kinetic energy in the event of a road collision. The thin-walled structure is emerging as a favorable geometry in designing the crash box. This article investigates the energy absorption performance of the corrugated nautilus shell bio-inspired thin-walled structure made of AA6061-T6 aluminum alloy. This structure’s performance was evaluated using finite element analysis (FEA) under quasi-static and dynamic loading conditions in an axial direction, then validated by a quasi-static compression experimental test, which showed satisfactory agreement. The results show that the corrugated nautilus shell bio-inspired thin-walled structure integrated with corrugated grooves reduced peak crushing force (PCF) by 17.9% and increased specific energy absorption (SEA) by 1.3% and crush force efficiency (CFE) by 17.6% compared to non-corrugated design. It can be concluded that the proposed nautilus shell bio-inspired thin-walled structure integrated with corrugated grooves has the potential to replace conventional hollow square designs in vehicle crash box applications.

    It is quite challenging to control both quality and productivity of products produced using injection molding process. Although many previous researchers have used different types of optimisation approaches to obtain the best configuration of parameters setting to control the quality of the molded part, optimisation approaches in maximising the performance of cooling channels to enhance the process productivity by decreasing the mould cycle time remain lacking. In this study, optimisation approaches namely Response Surface Methodology (RSM), Genetic Algorithm (GA) and Glowworm Swarm Optimisation (GSO) were employed on front panel housing moulded using Acrylonitrile Butadiene Styrene (ABS). Each optimisation method was analysed for both straight drilled and Milled Groove Square Shape (MGSS) conformal cooling channel moulds. Results from experimental works showed that, the performance of MGSS conformal cooling channels could be enhanced by employing the optimisation approach. Therefore, this research provides useful scientific knowledge and an alternative solution for the plastic injection moulding industry to improve the quality of moulded parts in terms of deformation using the proposed optimisation approaches in the used of conformal cooling channels mould.

    Generally in industry, the fluidization process involves with plate distributor and used a type of perforated plate distributor as their fluidization process. In terms of observation, this type of distributor has used a large amount of energy consumption. Currently, the new design of perforated plate that involved; (i) number of slotted, (ii) slotted width, (iii) slotted length and (iv) thickness distributor has been produced and tested via Computational Fluid Dynamics (CFD). Then, the results from the simulation in each perforated plate are been extracted and analyze by using a Design of Experiment (DOE) method through full factorial design (FFD). Results from the statistical analysis have shown a significant parameter on performance of the fluidization that was assessed by pressure drop values and velocity distributions values. The results from this statistical analysis showed a significant parameter on mean tangential velocity and pressure drop. In conclusion, by using the optimization method the new design of distributor would propose less energy consumption in future fluidization application.

    Warpage optimisation on front panel housing using straight drilled and conformal cooling channels in injection moulding process
    ( 2018)
    Mohd. Hazwan Mohd. Hanid
    Nowadays, there are various optimisation methods that have been explored by researchers to determine the appropriate setting of processing parameters in the injection moulding process. Based on previous researches, the use of optimisation works has improved the quality of the moulded part produced. Apart from quality, the productivity in the injection moulding process also plays an important role. Therefore, some researchers and manufacturers have introduced the application of conformal cooling channels in injection process which have been proven to improve the quality and productivity of the moulded part due to better uniformity of temperature distribution in the mould as compared to the conventional straight drilled cooling channels. However, the application of optimisation techniques to determine an appropriate setting of processing parameters in previous researches were mainly focused on the conventional straight drilled cooling channels, whereas in conformal cooling channels is still lacking due to the difficulties in mould fabrication. In this study, the application of optimisation technique to improve the warpage on the front panel housing using the conventional straight drilled and Milled Groove Square Shape (MGSS) conformal cooling channels was explored. Simulation studies using Autodesk Moldflow Insight (AMI) 2013 software were conducted to obtain the recommended processing parameters for both types of channels. Then, by selecting cooling time, coolant temperature, packing pressure and melt temperature as the variable parameters, Design of Experiment (DOE) has been constructed using the face-centered, Central Composite Design (CCD) approach. Response Surface Methodology (RSM) was performed to develop mathematical models to employing Glowworm Swarm Optimisation (GSO) and Genetic Algorithm (GA) optimisation approaches in order to determine the appropriate setting of the processing parameters to optimise the warpage defect. Results from experimental works showed that, the performance of MGSS conformal cooling channels is remarkably improved in terms of quality and productivity compared to the straight drilled cooling channels before and after optimisation. GA offers the lowest warpage value, followed by RSM and then GSO for both types of channels. The warpage on the front panel housing was improved by 32.5% (from 0.375 mm to 0.253 mm) and 22.9% (from 0.205 mm to 0.158 mm) using straight drilled and MGSS conformal cooling channels respectively after optimisation using GA, compared to the recommended setting suggested from simulation studies. Next, it was followed by an RSM approach with the improvement of 30.7% and 22% using straight drilled and MGSS conformal cooling channels respectively as compared to the recommended setting suggested from simulation studies. Lastly, the result using GSO approach showed an improvement of 18.7% and 7.3% using straight drilled and MGSS conformal cooling channels respectively when compared to the recommended setting suggested from simulation studies. Therefore, it can be suggested that, this research provides beneficial scientific knowledge and alternative solution for plastic injection moulding industries to enhance the quality of the moulded parts produced using optimisation techniques.

    The mold-making industry is currently facing several challenges, including new competitors in the market as well as the increasing demand for a low volume of precision moldings. The purpose of this research is to appraise a new formulation of Metal Epoxy Composite (MEC) materials as a mold insert. The fabrication of mold inserts using MEC provided commercial opportunities and an alternative rapid tooling method for injection molding application. It is hypothesized that the addition of filler particles such as brass and copper powders would be able to further increase mold performance such as compression strength and thermal properties, which are essential in the production of plastic parts for the new product development. This study involved four phases, which are epoxy matrix design, material properties characterization, mold design, and finally the fabrication of the mold insert. Epoxy resins filled with brass (EB) and copper (EC) powders were mixed separately into 10 wt% until 30 wt% of the mass composition ratio. Control factors such as degassing time, curing temperature, and mixing time to increase physical and mechanical properties were optimized using the Response Surface Method (RSM). The study provided optimum parameters for mixing epoxy resin with fillers, where the degassing time was found to be the critical factor with 35.91%, followed by curing temperature with 3.53% and mixing time with 2.08%. The mold inserts were fabricated for EB and EC at 30 wt% based on the optimization outcome from RSM and statistical ANOVA results. It was also revealed that the EC mold insert offers better cycle time compared to EB mold insert material.

    This study investigates the energy absorption characteristics of thin-walled tubes filled with rice husk and kenaf fibers when compressed under axial compression. The aim of this study is to evaluate the crashworthiness parameters such as energy absorption (EA), initial peak load (IPL), crush force efficiency (CFE) and specific energy absorption (SEA). Experimental results show that tubes filled with rice husk and kenaf exhibit significant improvements in overall energy absorption compared to empty tubes. However, while both fillers enhanced EA, the SEA values were lower than predicted. Thus, it is suggested that further optimization, such as adjusting filler density or exploring hybrid filler combinations, could improve crashworthiness. This study highlights the potential for rice husk and kenaf fibers as sustainable filler options for lightweight, impact-resistant designs in automotive, aerospace, and other engineering applications, with opportunities for improvement in future research.

    A thin-walled tube is an energy absorber device that is commonly used in automotive and locomotive applications. The function of this element is to convert the kinetic energy into other forms of energy during a collision that can minimize injuries to the passengers. Therefore, various studies have been reported previously to improve the thin-walled structure to decrease the damage and provide protection for the vehicle and occupant. This study aims to determine the effects of the cutout on the thin-walled tube when impacted under dynamic axial loading. The effects of sizes, shapes, locations, and the number of cutouts on the energy absorption characteristics have been analyzed by using the validated finite element model. The result indicates that a circular tube with a square cutout shape, larger cutout sizes, and near the top-end of the tube has more energy absorption characteristics. Furthermore, the results of energy absorption (EA), crush force efficiency (CFE), and specific energy absorption (SEA) are highest when applying four cutouts on the surface of the thin-walled tube. Research information provided in this study will serve as a guide in designing the cutout thin-walled tube for crashworthiness enhancements in the future.
