Design & Manufacturability
Injection mold design starts with the part. Geometry, shrink, gating, and side actions all determine how the mold must be built and how it will perform in production.

Cooling & Cycle Time
Cooling is the primary driver of cycle time and part stability in injection molding. Uneven cooling leads to warpage, shrink variation, and longer cycle times, while efficient cooling improves consistency and production output.
t \propto s^2
Cooling time increases with the square of wall thickness, making thermal design a primary driver of cycle time.

Gating & Flow
Gating controls how material enters the part and fills the cavity. Proper gate design ensures balanced filling, reduces defects, and improves dimensional stability.

Shrink & Dimensional Stability
Material shrink behavior affects part accuracy and must be accounted for in mold design. Cooling balance and material selection directly influence dimensional results.
