    The objective of this paper to improve the design of the torchlight when holding the torchlight and to increase the durability of the torchlight against water by using the float materials. The torchlight also has been analysed using Design for Manufacturing Assembly (DFMA), Failure Modes and Effect Analysis (FMEA), and Sustainability Analysis in order to provide better product.

    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 research focused on the redesign the main body of automatic air freshener dispenser. Automatic air freshener dispenser used for spraying fragrance automatically according to the setting provided. This type of air freshener no need to spray manually, labor saving and more convenient. This automatically air freshener dispenser will automatically spray the fragrance into the whole room space to purify air and remove smelly odor. Other than that, the objectives of this mini project are to redesign the main body of the automatic air freshener dispenser. The design of the automatic air freshener dispenser is using CAD software which is CATIA and then transfer to Finite Element Analysis (FEA) to analyses the capabilities of part design. At the end of this paper, this research will give understanding about design using CATIA Software and do analysis that improved the redesign body of the automatic air freshener dispenser.
