The name “H Frame” comes from the H-shaped frame structure ( two vertical columns with a connecting crossbeam) of the Power Press. It is also Known as Pillar Type (Straight-Side) Power Press.

H Frame Power Press is a heavy-duty press with two vertical Side columns (pillars) that provide stability and precision for high-tonnage operations.

RAM

RAM is Moving Vertically between Pillars implies force to Workpiece. In Mechanical H Frame Power Presses It Drives Power From the moving Flywheel.

Unlike C-type Power press, its closed-frame design reduces deflection, making it ideal for precision stamping, deep drawing, and forging.

Key Features & Design of H Frame Power Press

✔ Four-Pillar or Two-Pillar Frame – Ensures exceptional rigidity, stability, and strength.
✔ Hydraulic or Mechanical Drive – Hydraulic models offer better control, while mechanical ones are faster.
✔ Adjustable Bed & Ram – Allows customization for different dies and workpiece sizes.
✔ High Tonnage Capacity – Typically ranges from 50Ton to 1,000Ton+.
✔ Precision Guide System – Pillars ensure accurate alignment of the ram.

Types of Pillar Type Power Presses

A. Pneumatic Pillar type Press

Uses Pneumatic cylinders for smooth, controlled force.
Best for: Deep drawing, molding, and compression forming.
Advantages: Full tonnage throughout stroke, programmable pressure.

B. Mechanical Pillar Type Power Press

Flywheel & crank mechanism for high-speed operation.
Best for: Blanking, punching, and high-volume production.
Faster than hydraulic but less force control.

C. Servo-Driven Pillar type Press

Electric servo motor for precision and energy efficiency.
Best for: High-accuracy forming and automation.

Common Applications

Automotive Parts(body panels, chassis parts, gears, bearings).
Aerospace Components(precision metal forming).
Forging & Hot Stamping(high-strength parts).
Appliance Manufacturing: Washer drums, refrigerator panels
Electrical: Transformer laminations
Precision Stamping: Medical device components
Electrical Insulation Pressing(PCB laminates).

Why Basant H Frame power Press?

Basant Mechanical Is the Original owner of India’s Leading Power Press brand “BASANT”. our H Frame power Press also Know as pillar Type Power Press are essence of Power, Technology & Durability. With over 60 Years of Power Press manufacturing, Basant Mechanical Works is India’s Oldest & most trusted brand among H Frame Mechanical Power Presses. The Frame of Basant H type Power press is Welded of Stress Relieved Graded Steel, Nickel Bushes and Come with Adjustable Stroke. We manufacturer power Press from 20 tons to 1000 tons with Mechanical & Pneumatic Clutch and Die Cushion. Our H Frame Power press is great use for Drawing, Pressing, Stamping, Trimming, cutting, blanking & piercing purposes.

Salient Features of Basant H frame Power Press

Vibration Dampening System: Special frame design reduces vibration by 40% compared to conventional presses
Energy-Saving Flywheel: Optimized inertia reduces motor load by 15-20%.
Tonnage Capacity: from 50 tons to 1000 Tons.
Safety Standards: ANSI B11.1 Safety standards

Safety Systems in Basant Power Presses

Light Curtains– Infrared beam stops press if interrupted
Two-Hand Trip– Requires simultaneous button presses
Anti-Repeat Mechanism– Prevents double cycling
Tonnage Monitors– Detects overload conditions
Balancer Check Valves(for hydraulic) – Prevents sudden slide drop
Flying debris → Requires protective guarding.
Noise & vibration → Hearing protection needed.

How to Select Suitable H Type Power press?

Tonnage Requirement = (Material thickness × Shear strength × Perimeter) / 2,000
Bed Size – Must accommodate largest die + 20% clearance
Stroke Length – Typically 50-400mm (adjustable in hydraulic)
Shut Height – Distance between bed and slide at bottom dead center.

Maintenance Checklist

Daily: Check oil levels, inspect clutch/brake
Weekly: Lubricate gibs, check bolt tightness
Monthly: Inspect electrical contacts, hydraulic hoses
