• Objective: The aim of this research is to develop guidelines for the competency development of trainers in plastics molding injection factories (PMIF) in Thailand.

    Theoretical Framework: A mixed-methods framework is adopted, integrating quantitative data through statistical analyses like means, standard deviations, and regression, alongside qualitative insights from interviews. The framework explores relationships by combining numerical trends with thematic patterns for a comprehensive understanding.

    Method: The study population comprises 284 operators and 14 trainers. Data is collected through quantitative and qualitative approaches, including questionnaires and interviews, with statistical analysis applied using percentages, means, standard deviations, relationship analysis, and stepwise multiple linear regression.

    Results and Discussion: Guidelines for trainer competency development in PMIF in Thailand focus on three key areas—knowledge, skills, and attitude. Four sub-competencies in the knowledge domain influence training success: knowledge in 1) Teaching Psychology, 2) Trainers' Attitudes, 3) Behavior and Work Analysis, 4) Training and Counseling. In the skills domain, significant sub-competencies include: 1) Teaching Skills, 2) Listening Skills, 3) Computer Proficiency, 4) Behavior and Work Analysis Skills. The significant sub-competencies of the attitude domain include: attitudes toward 1) Modern Research, 2) Trainees' Intentions, 3) Teaching Psychology, 4) Trainers' Attitudes.

    Research Implications: Guidelines to enhance trainer competency in Thailand's plastics molding injection industry are provided. Findings influence training programs, workforce development, and industry productivity.

    Originality/Value: Key sub-competencies that predict training success are identified in the areas of knowledge, skills, and attitude. Structured approaches to enhance training success are provided, impacting professional practice and training outcomes in industrial settings.
