Precision Deep Hole Drilling for Injection Molds, Die-Cast Dies & Tooling
RuidCNC's deep hole drilling machines are the preferred choice for mold and die manufacturers worldwide. From cooling channel drilling to ejector pin holes, our machines deliver the precision and surface quality that mold making demands.
Deep Hole Drilling for Mold & Die Manufacturing
Cooling channel design is one of the most critical factors in injection mold and die-cast die performance. Properly positioned cooling channels reduce cycle time, improve part quality, and extend mold life. RuidCNC’s deep hole drilling machines give mold makers the precision and flexibility to drill cooling channels exactly where they are needed.
Challenges
Industry Challenges
Complex cooling channel geometries requiring angled and cross-hole drilling
Deep, small-diameter holes in hardened mold steel (up to 50 HRC)
Surface finish requirements for ejection and cooling performance
Minimizing cycle time while maintaining hole accuracy and straightness
Extended tool life requirements for large production mold runs
