SILVER

Bi-directional, multi radius and push and variable radius bending features. This process has been patented since 2002.

The system for moving the dies offers automatic changing of the bend radii of the same pipe, offering also right and left rotation in the same work cycle. The SILVER 2 CD, with its six controlled axes, stands at the top of the world manufacturers of pipe benders without mandrel, with an integrated orbital cutting system.

Application Fields

• Heat exchanger coils
• Industrial and domestic refrigeration and heating appliances
• Air conditioning & heating systems
• Electrical household appliances

Technical Characteristics

• RIGHT and LEFT, MULTI-RADIUS,PUSH & VARIABLE  bending capacity
• Capacity to bend annealed alloy pipes (Cu, Al, CuNi, CuZn): Ø16x1 mm
• Capacity to bend annealed alloy pipes Fe & SS: Ø16x0,5 mm
• Fully electric operation with Brushless motors with 6 controlled axes
• Working length of orbital arm 1100 mm (standard) other lengths when requested

The special feature of the bending arm, installed on the SILVER series of machines, offers the possibility of choosing from different lengths (1.100, 1.400 or 1.600  or others) in relation to the products to be made. A complete line of accessories allows a basic pipe bender to be adapted into a multi-function machine having various implementation and with standard prices.

Application Fields

• Heat exchanger coils
• Industrial and domestic refrigeration and heating appliances
• Air conditioning & heating systems
• Electrical household appliances
• Automotive components
• Taps and fittings
• Aeronautical & space industry components

Technical Characteristics

• RIGHT or LEFT bending capacity
• Capacity to bend annealed alloy pipes (Cu, Al, CuNi, CuZn): Ø 22x1 mm
• Capacity to bend annealed alloy pipes Fe & SS: Ø 22x0,6 mm
• Capacity to bend AISI 304 wire R=74KG/mm: Ø 6 mm
• Fully electrical operation with brushless motors
• Working length of orbital arm 1100/1400/1600 mm

This is a fully electric bending machine, that utilizes, in line, burr-free and chipless orbital cutting, mandrel-less bending, drilling and end-forming, all in automatic cycle.

The machinery can process very complex 3D shapes as it works, in the same cycle, left and right bends, multi radii and when necessary can easily operate on a push-bend system to also obtain variable radii bends.

Furthermore, the new bending system permits to achieve very short straights parts with different bending radii.

Mandrel bending kit Mod. PCA 16

This is an accessory that can be added to the bending group of the SILVER's serie.

The mandrel process is used when CLR - centre line radius - and wall thicknesses are rather low, to avoid the curves from collapsing. This bending process is generally required when a CLR is lower than 1,5 times the tube diameter or the wall thickness is less than 0,5 mm.

Working cycle:

1. Mandrel insert
2. Bending process
3. Mandrel extraction
4. Part splitting

Technical Characteristics

• Tube diameter: min. 7,94 max 16 mm.
• Bending length: max 100 mm.
