Specialized 200L Drum Tooling: L-Ring & Accumulator Head
A 10kg parison shot delivered in seconds generates intense thermal and mechanical clamping dynamics. Explore our three fundamental 200L drum engineering breakthroughs.
CAD SPECIFICATIONSParametric CAD Engineering & Parison Wall Control
Large 200L drums require calibrated wall thickness transitions. Our 3D CAD design balances axial parison elongation with radial stretch expansion, placing structural resin precisely into the top chime L-ring and bottom chime.
- Chime Thickness: Reinforced 8mm chime ring wall resists violent 1.8m diagonal drops
- Body Ribs: Rolling hoop geometry provides structural stiffness under 3-tier stacking
- Volumetric Tolerance: 200L capacity variance held strictly within ±0.5% (±1.0 Liter)
3D DIGITAL SURFACEDouble L-Ring Chime Geometry & FEA Stress Modeling
The top L-ring chime is the critical interface for universal forklift parrot-beak clamps and automated roll handling. Our 3D finite element stress simulations eliminate weak stress-concentration notches.
- Parrot-Beak Grip: Standardized ISO chime profile compatible with all international drum lifters
- Hydraulic Bung Plugs: Dual 2-inch top bungs (G2 fine & S56x4 coarse buttress threads)
- UN Drop Certification: Certified for 1.8-meter liquid drop impact at -18°C temperature
MACHINE PLATEN MOUNTINGHigh-Tonnage Machine Platen & Deep-Bore Cooling
Mounting an 8-ton mold block onto 150–300 ton accumulator blow molders requires rigid guide columns and high-velocity cooling water manifolds to maintain fast cycle times.
- Deep Gun-Drilling: Spiral cross-drilled cooling channels achieve >300 L/min flow rate
- Zero Mold Breathing: Pre-hardened P20 frame eliminates parting line flash under shot surge
- Bottom Cylinder: Integrated hydraulic cylinder drops bottom mold smoothly during ejection
Pre-Hardened P20 Steel & Hydraulic Drop Core System
Continuous parison clamping under 300 tons of hydraulic locking force requires massive structural steel integrity. Tour our specialized accumulator tooling features.
