High Impact Velocity Quench

High Impact Velocity Quench GRANCO CLARK has been supplying “High Impact Velocity” quenches since 1985. We documented the underlying science two decades ago in a seminar paper at the Extrusion Technology Symposium in 2004 (ET-04). 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 …

Profile Handling

Profile Handling  Dents, scratches, chill marks. These are the consequences of outdated conveyors and walking beam systems that can damage profiles, increase scrap, and increase operating costs. Delivering a flawless product isn’t just a lofty goal, it’s what our customers deserve. That’s the biggest reason for investing in GRANCO CLARK's automated profile-handling equipment.  With its superior degree of automation, our handling equipment will help you achieve maximum throughput. It will improve the overall surface quality of your product, reduce labor costs, scrap, physical effort and downtime. Your equipment is built to last, and to be serviced and repaired easily.  Run-Out Conveyors::  Equipped to handle maximum extrusion speeds Integrated cooling Run-Out Transfer Systems::  More Info

Pullers

Single

Single Puller When space or budget constraints don’t allow for the use of our Double or Twin Pullers, GRANCO CLARK's Single Pullers can still improve your productivity. They produce even, twist-free profiles and reduce scrap about 3% over operation without a puller. Line efficiency is further enhanced when you combine our Single Puller with the GRANCO CLARK under-table Hot Extrusion Saw.  Excellent Chip Collection Drop Away Rollers - No Lifting Simplest Design – Low Maintenance No Marking No Foundation Work Best Install Time Nine Modes of Operation Puller applies just the right amount of tension as the profile emerges from the die Suitable for use with …

Stretchers

Stretchers Stretching is one of the most critical post-quenching operations in the extrusion process. Performing that function correctly often makes the difference between usable product and scrap.  An overstretched profile will be out of tolerance.  A profile that is not stretched past its yield point will not be straight. Both are destined to become scrap.  GRANCO CLARK Stretchers deliver precise, accurate stretching, which enhances profile quality and keeps scrap to a minimum. When used in conjunction with our belt systems, our Stretchers straighten and batch profiles for efficient downstream operations.  GRANCO CLARK Stretchers accommodate a broad range of requirements. Our Stretchers are available in cam-style and controlled vertical crush jaw designs. No-man operational mode …

Saw & Gauge

Saw & Gauge Cutting large batches of extrusions is one of the keys to reaching high levels of productivity. Most existing Cut-off Saws have a limited width capacity, and are therefore inefficient and unproductive.  GRANCO CLARK's Extrusion Cut-off Saws are large-capacity, high-quality, high-performance saws that provide extremely close tolerances and an excellent cut surface finish. They are durable with low maintenance, and designed with safety in mind. GRANCO CLARK's Extrusion Cut-off Saws provide superior cut tolerance, maximum throughput, and safe operation by means of a process that involves minimum manual intervention. Superior Cut Tolerance:   High-capacity, high-performance saw ensures throughput  Advanced Automation:   Servo-controlled gauge head positioning  Safety:   More Info

Profile Stacking

Profile Stacking System GRANCO CLARK Stacking System are cost-effective and efficient solution for off-loading cut profiles from the gauge table to aging racks. It improves operator safety, reduces labor costs, and minimizes the risk of profile marking. With automated stackers and spacer insertion, the system is easy to use and will help you save time and money.  If you’re looking for a way to streamline your manufacturing process and improve your bottom line, consider investing in the GRANCO CLARK Stacking System.
