Deep core pins or tall walls cannot be cooled using standard straight-drilled lines.
Ideal for prototyping and low-volume production runs (under 10,000 cycles). Aluminum features excellent thermal conductivity and is fast to machine, but it lacks wear resistance against abrasive plastics. injection mold design guide
The mold can only be as good as the part design. Verify these first: Deep core pins or tall walls cannot be
Ensure the sprue taper is between 2° and 3° to allow easy pull-out during mold opening. injection mold design guide
Cooling accounts for roughly 70% to 80% of the entire injection molding cycle time. An optimized cooling system directly translates to higher throughput and lower part warp. Cooling Channels
Hardened steels used for high-volume production (over 1 million cycles). They withstand extreme clamping pressures and high processing temperatures.
