Products

CYLINDERS

Magnetic Cylinders

Magnetic Cylinders are crafted from premium tool steel, high-strength permanent magnets, and durable adhesive for exceptional accuracy and longevity. Use Bolted Bearer Design, with vacuum heat-treated bearers (60-62 Rockwell) ensure superior wear resistance.

Printing Cylinders

Constructed from premium aluminum or alloy, our lightweight cylinders provide exceptional concentricity, uniform color printing, and perfect registration, meeting both OEM specifications and global industry standards.

Standard Print Cylinders

Standard print cylinders, designed for letterpress, flexo, and combination presses, are available in various styles including Standard Aluminum, Integrated with Shaft, Assembly with Shaft, Bearers, Gears, and Sleeve.


Assembled Print Cylinders

Assembled print cylinders consist of the cylinder body, bearers, shaft, and gear, all assembled with high precision according to OEM specifications. The tight tolerances of body diameter, concentricity (TIR), and hardened ground gears ensure excellent print registration while minimizing gear and roller marks.

Sleeve Print Cylinders

Sleeve-type print cylinders are designed for specific flexo printing presses, featuring a fiberglass sleeve mounted inside the cylinder. The precise finish diameter ensures excellent registration and minimizes roller marks.



FLEXIBLE DIES

Standard Grade - Nickel Coated or Chrome Coated

Flexible Dies, made from premium European spring steel, undergo precise chemical milling and CNC machining. Blade height and spacing are micron-accurate, meeting the stringent demands of label printing, especially for electronics. Nickel or Chrome Plating ensures durability and corrosion resistance.


Premium Grade - Nano Diamond Coated

Flexible Dies utilizes top quality hardened spring steel imported from Europe, going through rigid chemical milling process, then to be finished by CNC machining. Blade height can be controlled within a few microns to designed TPH. Treated with Nano-Diamond coating technology, these dies offer excellent rust and corrosion resistance while significantly extending blade lifespan. Suitable for kiss-cut long run jobs, especially film labels used by auto-labeling process.

Solid Die - Rotary Cutters

Solid Engraved Rotary Dies can be designed and manufactured to suit various converting machines. According to different applications, Blade height and angle can be designed and made to suit various substrates, either kiss-cut from top, back cutting, or cut through applications.

Solid Die - Pin Ejection Rotary Dies

Pin Ejection Rotary Dies are praiticularly for cutting through thick cardboard or film materials, particularly when die-cut shapes require waste removal.



Solid Die - Air Ejection Rotary Dies

Air Ejection Rotary Dies are ideal for cutting single or multi-layer materials, or thin films, with die-cut shapes that require waste removal.




Solid Die - Air Suction Rotary Dies

Air Suction Rotary Dies are ideal for cutting single or multi-layer paper, film, cardboard, and self-adhesive label materials, where Pin Ejection or Air Ejection Dies may struggle with waste removal. These dies allow waste to be collected into blade cavities and suctioned off from the shaft.

Solid Die - Segment Rotary Dies

Segment Rotary Dies feature replaceable segment blades for areas that wear more quickly. This design allows customers to replace the worn segments themselves, eliminating the need to send the die back for repair.

Solid Die - Non Woven Rotary Dies

The Non-woven Rotary Die is commonly used for producing healthcare, hygiene, household, and decoration products, such as surgical masks, with ultrasonic welding and outline cutting dies.
