High Impact Velocity Quench

GRANCO CLARK has been supplying “high impact velocity” quenches since 1985. .

Cooling rate is determined by quench technology and profile thickness. For most crash box sections our systems can provide cooling rates of more than 200°F per second on enclosed hollows (that is - quenching only the outside of the profile).

GRANCO CLARK's High Impact Velocity Quench provides the maximum heat transfer available in a profile quench. Unlike flood quenches, the High Impact Velocity Quench penetrates the steam barrier surrounding the profile and puts water droplets directly on the aluminum. More importantly, the GRANCO CLARK High Impact Velocity Quench provides adjustability unlike any other, for a gain in profile quality.

With the GRANCO CLARK High Impact Velocity Quench, the speed of the cooling process is greatly increased—in fact, it can provide more than twice the cooling rate of a flood quench and three times the cooling rate of other spray quenches.

Pass-Through High Impact Velocity Quench System

• Unmatched Cooling Rates
• FEA Analyses For Any Shape
• Performance Guarantee
• Eliminate Distortion with Progressive Quenching
• All Stainless Construction
• Crash Profiles
• NO First Billet Scrap
• Perfect Guidance Through Quench on First Billet
• Ideal For Small Production Runs

• Puller and Quench work together to process the captive profile through the quench 
• A double seal on the puller traverse slot keeps the water in the quench
• Lowering rollers in the quench allow the puller jaw to operate at the same level as the rollers for optimum profile handling
• Revised puller head geometry moves the profile pick-up point closer to the press to minimize the time before the profile enters the quench 
• Specialized puller jaws pass through the quench with the clamped profile
• The puller electrics and saw motor remain outside the quench for maximum reliability
• Welding Dies:  for direct presses operating with welding dies, the first billet of each die can be fully processed by the quench, so there is no loss of usable material on the first billet
• Flat-Face Dies: for operation with flat-face (non-welding) dies, every billet can be captivated by the puller and processed through the quench
• Piercing Operation:  for piercing operation, each billet is processed through the quench and the double puller provides slug-cutting/handling capability
• Indirect Operation:  for indirect operation, each billet is processed through the quench and the double puller provides die stripping at the end of the extrusion
