Abstract
This research aims to improve the coconut fiber board production process at Dangtex Industrial Co., Ltd. The research data were collected from January to March 2022 and August to October 2022 for a total of 6 months. The data were used to identify the causes of problems in the coconut fiber board production process and to propose solutions for improving production using 7 QC Tools. The research found that Dangtex Industrial Co., Ltd. produced 107,244 pieces of coconut fiber board. The survey data collected before the improvement, from January to March 2022, showed that a total of 6,491 sheets were wasted, representing 6.44% of the total production. The value of the waste was 5,841,900 baht. The problems in the production process were as follows: The workers lacked knowledge and skills. The machines were not maintained and were not checked regularly. The pressure used to compress the coconut fiber boards was too high or too low. A process had too high or too low temperature. The number of sheets baked at a time was too high or too low. The raw materials were dirty and had stones mixed in. The raw materials were wet and had high humidity. The researcher proposed the following solutions to the problems: for the problem of workers, training and education should be provided to the employees. The problem of machines, the machines should be checked regularly to ensure that they are in good working condition. Before the improvement, the machines were not checked regularly. The researcher arranged for the machines to be checked every week before operation. The problem of process, a work manual should be created. The problem of raw materials, a warehouse should be set up for raw materials and the coconut fiber boards should be cleaned. After implementing the proposed solutions, the researcher collected data on the production process improvement process from August to October 2022. The results showed that the amount of waste was reduced to 4.49%.
