Nargesa PI85 Hydraulic Press for Locks 

The Nargesa PI85 Hydraulic Press for Locks is a specialized hydraulic punching machine designed to quickly and accurately create lock casing, cylinder and handle openings in square and rectangular steel tubing. Patented by Nargesa in 2006, the PI85 is designed to accommodate approximately 85% of lock models on the market, making it a practical production solution for manufacturers of metal doors, gates, fences and other tubular steel structures.

The PI85 dramatically reduces the time required to prepare steel tubing for lock installation. A process that can traditionally require 30 to 45 minutes of manual measuring, cutting, drilling and finishing can be completed in approximately 58 seconds using the dedicated two-station punching process.

The machine can process square and rectangular tubing ranging from 35 × 35 mm up to 50 × 80 mm, with supported wall thicknesses of 1.5 mm or 2 mm. It can be configured for mild steel, galvanized steel and stainless steel, providing flexibility for a range of door, gate and architectural metal fabrication applications.

The first working station creates the lock mechanism opening, while the second creates the cylinder and handle openings. An internal core supports the tubing during punching to help prevent deformation, while integrated stops and adjustable positioning controls help maintain accurate, repeatable results.

With adjustable lock positioning from 18 to 37 mm, dedicated tooling for common tube dimensions and multiple punching configurations, the PI85 transforms lock preparation from a time-consuming manual task into a fast and repeatable production operation.

Manufactured in Spain, the Nargesa PI85 is designed for professional production environments and complies with CE industrial machinery manufacturing standards.

Key Features 

• Approximately 58-second cycle time – Completes the lock preparation process significantly faster than conventional manual fabrication.
• Designed for approximately 85% of lock models – Accommodates a broad range of common lock configurations.
• Two dedicated working stations – Separates lock mechanism punching from cylinder and handle punching.
• Processes tubing from 35 × 35 mm to 50 × 80 mm – Covers many common square and rectangular tube sizes used in door and gate manufacturing.
• Supports 1.5 mm and 2 mm wall thicknesses – Dedicated tooling is available for common production materials.
• Mild steel, galvanized steel and stainless steel capability – Provides flexibility for different fabrication requirements.
• Internal tube support – Helps prevent deformation during the punching process.
• Adjustable lock entrance position – Allows adjustment from 18 to 37 mm for different lock configurations.
• Adjustable lock mechanism opening – Allows the machine to be configured around the lock being installed.
• Multiple punching configurations – Can punch the mechanism, cylinder and handle openings in different combinations.
• Repeatable positioning – Integrated stops help maintain consistent opening locations across production runs.
• Reduced manual finishing – Minimizes the need for drilling, grinding, filing and rework.
• Ready-to-install results – Produces precise openings designed to simplify lock installation.
• Safety foot pedal – Allows hands-free cycle activation while the operator positions and supports the tubing.
• Production-focused design – Well suited to repetitive door, gate and tubular steel fabrication.
• Palletized lower base – Makes the machine easier to position within the workshop.
• Fully assembled delivery – Reduces installation and setup requirements.

Applications

The Nargesa PI85 is designed primarily for manufacturers working with square and rectangular steel tubing where consistent lock preparation is required.

Typical applications include:

• Metal doors
• Security doors
• Pedestrian doors
• Entry gates
• Large gates
• Fence gates
• Security barriers
• Metal grilles
• Architectural metalwork
• Tubular steel structures

The PI85 is particularly valuable for repetitive production where the same lock openings must be created across multiple identical frames.

The machine can perform several different punching configurations, including:

• Lock mechanism, cylinder and handle openings on both sides
• Lock mechanism, cylinder and handle opening on one side
• Lock mechanism and cylinder opening without a handle opening
• Cylinder opening only
• Handle opening only

This flexibility allows manufacturers to configure the machine around different door and gate designs rather than relying on a single fixed punching sequence.

The PI85 can also create a production opportunity for businesses supplying pre-punched, ready-to-assemble tubing to other manufacturers, fabricators or door and gate producers.

Why Choose the Nargesa PI85?

The biggest advantage of the Nargesa PI85 is the amount of time it can save on repetitive lock preparation.

Preparing a tubular steel door or gate for lock installation manually can involve measuring, marking, drilling, cutting and filing multiple openings. The PI85 combines these operations into a dedicated production process that can complete the required preparation in approximately 58 seconds.

The machine is also designed around repeatability. Its dedicated tooling, internal tube support, integrated positioning stops and adjustable lock entrance help maintain consistent opening locations from one tube to the next.

The internal support core is especially important when punching thin-walled tubing, helping reduce the risk of deformation during the lock mechanism punching operation.

For manufacturers producing doors and gates in volume, the PI85 can help:

• Increase production throughput
• Reduce repetitive manual fabrication
• Minimize finishing and rework
• Improve consistency between parts
• Reduce assembly time
• Free skilled fabricators for higher-value work
• Create opportunities to supply pre-punched tubing to other manufacturers

The PI85 is purpose-built for a specific manufacturing problem: preparing square and rectangular steel tubing for lock installation quickly, accurately and repeatedly.
