Who uses the AT 1020-100 and for what
The Bernardo AT 1020-100 is the universal low-force press in the AT family, sized for operations requiring generous useful height (680 mm, the highest in the family) but not maximum forces. The 680 mm useful height is the highest value among Bernardo AP/AT universal presses: it allows for processing of tall molds and vertical components that AP presses with 275 mm cannot accommodate, and even the AT 1520-150 with 610 mm cannot reach. The 100 tons are sized for tall molds that require distributed, not concentrated, pressures. In Krollit customer workshops, it is chosen by mechanical workshops with deep molds, manufacturers of vertical components (cylinders, tall shafts), and prototyping laboratories that alternate different molds.
Its place in the Bernardo range
The AT 1020-100 is the entry-level model of Bernardo's AT family. Above it are the AT 1020-150 (same width, 150 t, 610 mm height) for more force but less height, and the AT 1520-150 (1,520 mm width, 150 t, 610 mm height) for wider workpieces. A distinctive feature of the AT 1020-100: it has the most extended useful height in the family (680 mm vs 610 mm for other ATs). This design choice makes sense: with lower tonnage, the structure can be taller without compromising stability. For workshops that work with very tall molds but do not require 150 tons, the AT 1020-100 is the most targeted choice in the range. For those who want more force and accept 70 mm less height, they can move up to the AT 1020-150 or AT 1520-150.

Original Bernardo tools, spare parts, and accessories available from stock with 3-5 business day shipping. Customer support available in Italian.
Who is the AT 1020-100 for?
| Profile | Compatibility | Reason |
|---|---|---|
| Passionate hobbyist | Not recommended | Industrial machine with a weight of 2,800 kg and requiring a 400V three-phase line. Exclusively professional application. |
| Workshop with deep and tall molds | Recommended | Useful height of 680 mm is the most extended in the AT family. Allows molding on tall vertical components that would require specialized industrial presses. |
| Manufacturer of vertical components | Recommended | For cylinders, tall shafts, vertical assemblies. 100 tons are adequate for distributed pressures on tall molds. |
Not recommended for: applications requiring over 100 tons (consider AT 1020-150 at 150 t); flat machining that does not utilize the 680 mm height (the AP 1020 is more economical); parts wider than 1,020 mm (consider AT 1520-150); workshops without an industrial 400V three-phase line.

Frequently Asked Questions
Why does the AT 1020-100 have a useful height of 680 mm, while the AT 1020-150 only has 610 mm?
With lower tonnage (100 vs 150 t), the structure can be designed taller without compromising overall stability. It's a deliberate trade-off: less force but more vertical space.
The 50 fewer tons allow for a less massive but taller structure. For workshops that prioritize mold height, this choice is strategic. Workshops that require maximum force with intermediate height choose the AT 1020-150. Those who want both characteristics at their maximum must switch to dedicated industrial presses outside the universal AP/AT range.
What is the practical difference with the AP 1020-100 (100 t, 1,020 mm width)?
The AP 1020-100 does not exist in the standard Bernardo range: for 100 t and 1,020 mm width, only the AT version with 680 mm useful height exists. For 100 t in AP format, the AP 1520-100 (1,520 mm width, 325 mm height) is needed.
The AP range is optimized for limited heights (275-325 mm), the AT range for extended heights (610-680 mm). Bernardo does not offer all possible combinations: for each width-tonnage configuration, it chooses the useful height consistent with typical use.
Is the 7.5 kW motor sufficient for continuous use?
Yes. The motor is sized for continuous cycles with an advance speed of 8 mm/sec. For series production with standard cycle times, the AT 1020-100 operates without thermal limitations.
The 7.5 kW power consumption is manageable by standard industrial control panels without special sizing. For workshops with limited available power, the AT 1020-100 is the most accessible choice in the AT family (the AT 1020-150 requires 11 kW).
Can I work with components larger than 500×1,020 mm?
Only if the part fits on the table in a different orientation or if the pressing is concentrated in an area that falls within the table. For consistently larger parts, consider the AT 1520-150 (600×1,520 mm table).
The lower table of the AT 1020-100 is 500×1,020 mm: the part must rest on this surface for pressing. Wider parts can overhang laterally if they do not require pressure in that area. For series production on larger parts, it is recommended to switch to a properly sized press.
How much operational space is needed in the workshop?
The machine dimensions are 2,150 × 1,400 × 2,480 mm. For workpiece handling, an operational area of at least 3.5 × 3 m with a minimum ceiling height of 3 m is required.
The height of 2,480 mm allows installation in workshops with standard 3-meter ceilings. The weight of 2,800 kg is the lowest in the AT family, facilitating initial installation and handling.
