Crest Clamshell
The No More Make-Ready Clamshell
The Crest Clamshell represents over 30 years of clamshell engineering, all with the singular focus of eliminating your make ready and providing you with a solid return on your investment.
By reducing setup times, your company will run more jobs with less waste, which is one way that our customers cost justify replacing an old clamshell or a so-called value-oriented press. Over a short period of time low-grade metals on ‘value-oriented’ clamshells wear, causing operators to spend hours setting up and readjusting the make ready. This added make ready not only increases the cost of running a job, but it also results in more wasted sheets because operators need more set-up sheets, which is especially costly with today’s pay-per-click digital printers.
Since we all want to avoid make ready, let’s define the term to ensure we eliminate all of the potential problems. Clamshell make ready is determined by three important factors:
- The quality of the press
- The right die for the job
- The flatness of the platen
From a clamshell engineering perspective, you want the strongest press available, not necessarily because you need the sheer tonnage to cut the material, but more importantly, because the stronger the press, the less deflection. The Crest Clamshell achieves its ‘No Make Ready’ label, in part, because it’s designed as a high-tonnage clamshell that will handle some of the industry’s toughest substrates, such as polycarbonates, polyesters and polystyrenes while eliminating deflection. To provide you with added strength, the Crest Clamshell includes the following as standard features:
- Welded steel frame as opposed to a cast frame of recycled metals
- Strong main gears designed to stop on impression without locking up the press Interlocking steel frame designed to handle heavy loads
- Although the many advanced features may sound expensive, the Crest Clamshell actually provides the lowest cost of ownership. The Crest Clamshell lowers operating costs by eliminating wasted time and material, minimizes downtime and is built to last 25-30 years, as opposed to the 5-7 years standard for ‘value-oriented’ presses.
- The manufacturers of this press not only provided a flat platen to decrease operators’ make ready, but they also included features to ensure that any operator could run the press, regardless of his or her skill set.
- Precision micrometre adjustment: simply spin a dial to fine tune your press to .0001 of an inch.
- Impression Throw Off: If an operator misplaces a sheet, he or she can easily disengage the press before it ruins that sheet.
