One of the Melaka casting firms was facing an issues regarding the current hood placement on the casting machine. the current hood placement design was so poor at capturing scattered chips. The placement was not as close to the emission source as possible, leading the chips to be spread in different directions. To solve the problem, the House of Quality (HOQ) received an analysis based on feedback from industrial members. The HOQ was used to identify the preferable criteria for hood location, with “ease of maintenance” scoring the highest at 26.67%, followed by “stable and safe,” which scored 22.22%. Then, three innovative designs were offered from the HOQ result specification, and following consultation with the external engineers involved in the process. In addition, the Pugh was employed to determine the best hood placement. Finally, the concept of Design-3 was selected with a concept score of 3.9. The outcome shows that by using Kaizen, the time required to clean the equipment is to be reduced. As a result, the company's production has increased due to the reduction of 90 minutes of cleaning time.
