About Round Support Pillars
Round support pillars are the standard choice for mold plate support. Through-hardened SUJ2 bearing steel (HRC 58-62) provides maximum compressive strength. Available in Ø20-50 mm with precision-ground heights to ±0.01 mm.
Application Scenarios
High-Tonnage Production Molds
Production molds under 300+ ton clamping need maximum support to prevent plate deflection and parting line flash.
Why it fits: Round pillars in SUJ2 provide the highest load capacity per unit cross-section (80 kN @ Ø40 mm), with HRC 58-62 hardness resisting compressive deformation.
