At QQS, mold design is more than creating tooling drawings—it is the foundation of successful mass production. With over 20 years of experience in precision injection mold design, our engineering team focuses on manufacturability, product quality, mold life, and production efficiency from the very beginning.

Before tooling starts, we work closely with customers to optimize part design through DFM (Design for Manufacturing) and Moldflow analysis, helping identify potential molding issues, reduce development risks, and shorten the product launch cycle.

Our mold designs are engineered for high precision, easy maintenance, stable production, and long service life. Every project is tailored to achieve the best balance between quality, cost, and production efficiency.

Our Mold Design Expertise

• Gate System – Optimized gate selection, hot runner or cold runner solutions, supported by Moldflow analysis.

• Guide System – High-precision guiding with reliable wear-resistant components for long-term stability.

• Molding System – Insert-based designs for easier maintenance and improved dimensional accuracy.

• Slide System – Durable mechanical slide designs whenever possible, minimizing hydraulic complexity.

• Ejector System – Optimized ejector pin, blade, or block layouts for reliable part ejection.

• Cooling System – Efficient cooling channel design, including conformal cooling solutions where required.

• Venting System – Scientifically designed venting to reduce burn marks, air traps, and surface defects.

Every mold is engineered with one objective: stable production, consistent quality, and lower manufacturing costs for our customers.
