Masterwork Unveils Faster Duopress

December 6, 2016  By PrintAction Staff

Masterwork USA, a finishing manufacturer of folding carton and packaging equipment headquartered in Tianjin, China, introduced its newest Duopress model: the MK21060STEs foil stamping and die-cutting machine. The company explains its engineers have designed the new model to incorporate better stability, additional technology and a faster maximum speed of 6,000 sheets per hour.

“We’re pleased to unveil the Duopress MK21060STEs for the post-press market,” said Wayne Zheng, Marketing Manager for Masterwork USA. “Our expert research and development team have designed a new and exceptionally better computerized foil controlling system, which can handle complex foil advance calculations to help reduce foil usage of up to 60 percent.

“They’ve increased the speed on the Duopress to 6,000 sheets per hour,” continued Zheng, “which is really 12,000 sheets per hour because it is producing three processes in one pass through the press: foil stamping, die-cutting, and stripping… Masterwork is the only company to offer this type of machine.”


The Masterwork Duopress machines are designed with both foil stamping and die cutting functions in one pass, explains the company, to provide increased accuracy and efficiency. One pass offers register between die-cutting and foil stamping. If an operator has to feed the paper through two machines, explains Masterwork, the positioning of the paper may be slightly different and the die-cut and foil stamping might not be as accurate.

The machine can also be optioned to stamp two separate foil applications in one pass in its two platens. The foil stamping system on the MK21060STEs is equipped with three longitudinal foil advance pulls and two transversal foil advance pulls.

The Masterwork Duopress MK21060STEs is designed with a non-stop feeder. A pile change can be achieved while the machine is in operation with the help of non-stop swords. Adjustments on the feeder can be made with micro adjustments.

Masterwork explains the Duopress MK21060STEs has enhanced tension control during foil feeding and its error tolerance of 1 mm during foil unwinds. A PID heating system controls its 20 independent heating zones. The operator workload is reduced due to a pneumatic plate locking device.

The machine’s stripping station features stripping frames, a stripping concave template, and stripping boards. The transmission mechanism and cam movement curve are designed for stripping stability and accuracy. The centre-line registration system used for the stripping board provides accurate positioning and easy adjustment.

The non-stop delivery system is equipped with a delivery curtain. The delivery system has a double-sided pneumatic operating system, making it quicker and easier to control. An additional benefit in the delivery is the pneumatic sampling device, explains the company, which allows the operator to check the product as the machine is in production. The machine operator is provided with two fullly functioning top screens to control production. The screens display every machine function, including working speed, yield, fault diagnosis, and pressure.
“The past 20 years has seen rapid product development,” said Zheng. “Masterwork has introduced six major lines including 70 different specification products, covering hot foil stamping, die-cutting, inspection, folding-gluing, digital inkjet, and gravure printing presses.”
