3. Problems in Gear Manufacturing Industry

3.1 Manufacturing Process Needs Optimization

Low Standardization and Normalization: Different enterprises use different process parameters and operation methods in gear manufacturing, resulting in inconsistent product quality. This not only affects product performance and service life but also has a negative impact on the industry’s image and reputation.
| Company | Process Parameter | Product Quality Consistency |
|–|–|–|
| Company A | Parameter X | Inconsistent |
| Company B | Parameter Y | Inconsistent |
Limited Automation: Although some advanced manufacturing processes and technologies such as CNC machines and robots have been widely used, some gear manufacturing enterprises have not fully adopted these technologies, resulting in low production efficiency and quality control difficulties.
Insufficient Precision Control: The precision of gears has a crucial impact on product performance and service life. However, some enterprises have problems with imprecise precision control. For example, when manufacturing aerospace engine gears, some enterprises use CNC machines and ordinary machines with large precision errors, resulting in large tooth profile errors and inability to detect fine errors and geometric tolerances.

3.2 Technical Talent Shortage

Insufficient Supply: Gear manufacturing requires a high level of technical knowledge such as precision machining, numerical control technology, and materials science. However, the supply of high-level technical talents is insufficient. The training scale of gear manufacturing majors in many universities and vocational schools is limited, unable to meet the industry’s development needs.
Serious Talent Loss: Due to the high technical requirements of gear manufacturing, some enterprises often hire technical talents with high salaries. However, due to the lack of talent cultivation mechanisms and long-term incentive mechanisms, it is difficult to retain excellent technical talents.
Unreasonable Talent Structure: The age structure of technical talents in the gear manufacturing industry is mostly inclined to be older, with relatively fewer young technical talents. For example, in a certain enterprise, 60% of technical talents are over 45 years old, and 30% are under 30 years old.
Incomplete Talent Cultivation System: The talent cultivation system for gear manufacturing is relatively weak, making it difficult to cultivate excellent technical talents and hindering the industry’s development to some extent.

3.3 Weak Brand Building Capacity

Lack of Understanding of Brand Value: Some gear manufacturing enterprises only regard the brand as a symbol or name, ignoring its value and significance, resulting in a lack of differentiation and competitive advantage in the market.
Vague Brand Positioning: Many gear manufacturing enterprises do not have a clear brand positioning strategy, making it difficult to define their position and target customer groups in the market accurately.
Insufficient Investment in Brand Promotion: Many enterprises do not fully utilize various brand communication channels such as advertising, publicity, and social media to enhance brand awareness and recognition but rely more on traditional sales channels such as agents and distributors, resulting in ineffective brand image dissemination and promotion.

4. Solutions for Gear Manufacturing Industry

4.1 Optimize Manufacturing Process

Establish Unified Standards: Formulate unified gear manufacturing standards, including material selection, heat treatment process, and processing equipment requirements, to ensure product quality consistency and stability.
| Standard Aspect | Specification |
|–|–|
| Material Selection | Material X for certain applications |
| Heat Treatment Process | Temperature range, time limits |
| Processing Equipment Requirements | CNC machine accuracy requirements |
Introduce Advanced Technologies and Equipment: Adopt advanced processing equipment and technologies such as CNC machines for high-efficiency and high-precision gear processing and robots for automated production line operations to improve production efficiency and quality.
Strengthen Cooperation with Research Institutions and Universities: Collaborate with research institutions and universities to jointly conduct research work, improve enterprise technical level and innovation ability, and develop new high-performance materials for gear manufacturing.
Master Stable Processing Techniques: Study and master stable processing techniques to reduce precision fluctuations in the gear manufacturing process. For example, accurately control parameters such as temperature, time, and cooling speed in key processes such as heat treatment to ensure the hardness, structure, and performance of gears meet requirements.
Establish a Complete Detection System: Use advanced detection equipment and tools such as three-coordinate measuring instruments to accurately detect and control the precision of gears, ensuring product accuracy and quality.

4.2 Meet Technical Talent Needs

Strengthen Talent Supply: Universities and vocational schools should strengthen cooperation with enterprises, adjust curriculum settings according to industry needs, and cultivate more talents with practical operation skills and theoretical knowledge.
Establish Long-Term Incentive Mechanisms: Gear manufacturing enterprises should establish long-term incentive mechanisms such as equity incentives, bonus incentives, and career development incentives to attract and retain excellent technical talents. At the same time, personalized incentive schemes can be formulated according to the different needs of employees.
Improve Technical Talent Structure: Enterprises should increase the introduction of young technical talents, provide a good working environment and development space, and establish a complete technical talent echelon. Through the old – leading – new method, young technical talents can adapt to work quickly and improve their technical level.
Strengthen Talent Cultivation: Enterprises should cooperate with the government to formulate a complete technical talent cultivation plan and scheme, including vocational training, skill improvement, and practical experience accumulation. At the same time, enterprises can strengthen cooperation with schools to jointly cultivate technical talents through joint training programs and internship base construction. School – enterprise cooperation can also be carried out for scientific research to improve the practical and innovative abilities of technical talents.
