玉熇 张.-Simulation Engineer; Injection Mold Engineer

First Development of Light Guide Products

• Discussed mold solutions to prevent appearance defects such as weld lines and ejector pin marks from affecting light guide performance;
• Coordinated equipment resources across locations and optimized injection molding processes to prevent defects such as black spots and yellowing;
• Coordinated testing equipment across sites, conducted final assembly verification, and prepared development specifications for light guide products.

Mold Design and Review:

• Led mold solution reviews for new products and proposed design improvements to avoid subsequent mold modifications.
• Responsible for defining mold solutions for major projects, including large automotive interior components such as instrument panels, door panels, and center consoles.
• Established a mold design standards library and mold flow analysis report templates, including gate design solutions for 28 types of products, mold structure standardization, and summaries of mold issues.

Process Optimization and Innovation:

• Prepared injection molding process sheets based on mold flow analysis results. Achieved 90% accuracy for non-appearance components and improved trial molding efficiency by 20%.
• Introduced conformal cooling technology and applied 3D-printed conformal cooling channels to 5 sets of molds, reducing cooling time by 25%.
• Managed UDB data from material suppliers, improved consistency between the data and material properties, and increased the accuracy of mold flow analysis.

Cross-Department Collaboration and Cost Control:

• Worked with the product design department to provide product structure optimization solutions, avoid molding risks, and reduce labor costs.
• Collaborated with the material development department to control material performance, establish testing standards, verify material properties, and build a material database.
• Communicated with external suppliers to mitigate potential product risks, determine mold solutions, and negotiate subsequent mold modification plans.

Mold Design and Development:

• Independently completed the full 3D design of 35 injection molds, including complex slider mechanisms and lifter mechanisms.
• Designed 2 large multi-cavity molds and optimized the cooling channel solutions through simulation analysis, increasing production efficiency by 100%.

Mold Flow Analysis and Optimization:

• Completed 250+ mold flow analyses using Molditow, covering filling, cooling, warpage, fiber orientation, and other analysis types.
• Established the company's standard mold flow analysis process, achieving 95% analysis accuracy and providing reliable data support for design.
• Optimized gate positions and warpage through analysis, reducing injection pressure by 20% and potential defects by 30%.

Project Management and Technical Support:

• Responsible for mold development for 8 automaker projects, with a cumulative project value of 2000+万元.
• Provided on-site technical support to the manufacturing department and resolved technical issues during trial molding.
• Established a mold flow analysis checklist, reducing the work error rate from 5% to below 1%.

• Responsible for mold design for 15 consumer electronics products, including home appliance accessories and daily-use products for export.
• Completed runner balance design for 6 sets of molds, with a one-time design approval rate of 90%.
• Introduced early-stage verification through mold flow analysis, reducing the average number of mold trials from 4 to 2.
