Description

The IMPRESS Hard Case Corner Rounding Machine (Single Head) is a specialized pneumatic solution designed to seamlessly transform sharp book and case corners into smooth, professional curves. Engineered for superior finishing quality, both the top and bottom dies are equipped with built-in heating elements, complemented by advanced heating controllers that allow you to precisely adjust the temperature based on your specific glue and media requirements. Powered by a robust pneumatic cylinder, the machine also features an integrated timer, giving operators complete control over the dwell time for consistent, flawless results every time.

Designed for maximum versatility in production, this machine features interchangeable dies ranging from R3 to R15, allowing you to easily switch between different radius sizes to suit various project specifications. Each machine comes complete with one set of dies of the customer’s choice to get you started right away. Combining high-pressure pneumatic performance with intelligent thermal control, it ensures clean, durable, and bubble-free corner rounding for luxury books, diaries, and rigid case-bound products.

FAQ

1. How does the IMPRESS Hard Case Corner Rounding Machine operate?

It is a single-head pneumatic machine powered by compressed air (0.6 MPa) that uses heat and pressure to cleanly round sharp corners on books, diaries, and rigid cases.

2. Why do both the top and bottom dies have built-in heating elements?

The dual heating elements melt or soften the glue and cover materials (such as leatherette, paper, or fabric) around the corner, ensuring smooth, durable, and bubble-free edges without cracking.

3. What radius sizes (die sizes) are available for this machine?

The machine supports interchangeable dies ranging from R3 to R15. It comes standard with an R6 die, or you can select one die set of your choice upon ordering. Additional dies are available separately.

4. Can I adjust the temperature for different materials and glues?

Yes. The machine includes advanced heating controllers that allow operators to precisely regulate temperature based on the media, cover thickness, and adhesive type being used.

5. What is the purpose of the integrated timer?

The integrated timer lets you set the exact dwell time—the duration the heated pneumatic press holds the corner—to ensure consistent, uniform results across every batch.

6. What electrical setup and air supply are required?

The machine operates on a standard 230V, Single-Phase, 50 Hz electrical supply and requires an external air supply delivering 0.6 MPa pressure.

7. Is this machine suitable for heavy-duty rigid hard cases?

Yes. Engineered specifically for hard-case finishing, its high-pressure pneumatic cylinder easily handles thick boards used in luxury books, hardbound diaries, and rigid boxes.

8. How easy is it to change the rounding dies?

The machine features quick-change interchangeable dies, allowing operators to switch between different corner radius sizes (R3–R15) with minimal downtime.

9. What are the dimensions and weight of the machine?

The compact desktop unit measures 650 × 330 × 420 mm and weighs approximately 38 kg, making it ideal for print shops and binderies with limited space.

10. What comes included with the machine purchase?

The machine comes ready to operate with a single-head unit, integrated thermal/timer controls, and one complete die set of your choice (default R6).
