Strengthening Theory, Enhancing Practice, Empowering the Full “R&D–Production–Sales” Value Chain
Junhua Group Injection Molding Machine Setup Skills Training & Competition
To further deepen core injection molding technologies for high-performance engineering polymers such as PEEK (Polyether Ether Ketone) and to cultivate multi-skilled professionals who are theoretically grounded, operationally proficient, and optimization-oriented, Jiangsu Junhua Special Polymer Materials Co., Ltd. organized a specialized Injection Molding Machine Setup Skills Training & Competition.
The competition successfully concluded on January 15, 2026. Under the theme “Strengthening Theory, Enhancing Practice”, the event closely aligned with the company’s full R&D → Production → Sales value-chain strategy. Through competition-based learning and skill reinforcement, the program injected strong technical momentum into Junhua’s high-quality development.
PART 1 – Theory + Practice
As a critical link between R&D and mass production delivery, injection molding process accuracy directly determines product performance and market competitiveness. The competition precisely addressed this core challenge by combining systematic training with high-intensity practical assessment, bridging the gap between technical development and scalable manufacturing, and embedding skill advancement across the entire business chain.
Dual-Track Evaluation System
The competition adopted a dual-track evaluation model of “theoretical assessment + practical competition.”
Final scores were calculated with 30% theory and 70% practical performance, ensuring a solid technical foundation while emphasizing real-world operational capability.
1. Theoretical Assessment
The theoretical examination focused on key topics including:
- PEEK material characteristics
- Injection molding principles
- Safety operation standards
- Process parameter optimization
- Defect analysis and corrective measures
This section evaluated participants’ depth and systematic understanding of injection molding processes for high-performance polymers, ensuring precise alignment between material properties and process logic.
2. Practical Competition
The practical competition delivered an intensive and engaging on-site challenge. Participants from the Sales Department, R&D Department, and Tooling Department competed together, focusing on the injection molding of PEEK components.
Strictly benchmarked against real production scenarios, contestants were required to complete the full process within a limited timeframe, including:
- Mold setup and adjustment
- Injection parameter configuration
- Molding defect troubleshooting
- Dimensional accuracy inspection
Key evaluation criteria included operational standardization, parameter optimization capability, and problem-solving efficiency.
Participants demonstrated calm execution and technical proficiency, skillfully controlling equipment and precisely adjusting critical parameters such as temperature, pressure, and holding time. By optimizing molding strategies for PEEK’s high-temperature resistance and high-strength characteristics, they rapidly resolved common issues such as poor flow and product deformation, showcasing solid hands-on expertise and a strong commitment to craftsmanship.
The judging panel conducted rigorous scoring based on operational procedures, molding efficiency, product accuracy, and safety compliance, ensuring fairness and objectivity throughout the competition.
PART 2 – The Results of Excellence
“This competition was not only a test of skills, but also a platform for technical exchange.”
The event awarded first, second, and third prizes, establishing a structured reserve of skilled talent. Outstanding performers were incorporated into key talent development programs, strengthening the foundation for future technological innovation and capacity upgrades.
Junhua Group consistently adheres to the talent development philosophy of “full participation and continuous improvement.” By implementing the PDCA cycle management model, and through diversified initiatives such as skills competitions, mentorship programs, and innovation task forces, the company has built a complete skill development system covering cultivation, motivation, application, and knowledge transfer.
This specialized injection molding competition represents a key practice in deepening the integration of training with competition and production with skill development. By embedding material research insights from R&D, process optimization requirements from production, and quality assurance standards from the market into the entire competition, Junhua ensures that skilled professionals can both align with R&D directions and efficiently support mass production—ultimately forming a virtuous cycle where technology empowers production and production supports the market.
