For all applications where lift movements are required parallel to mould opening, it is possible to use gas springs.
The FIBRO Mould Line gas spring (FML), which was specially developed for mould making, is characterised by its high force, its small size, a long service life of at least 1,000,000 strokes and a constant operating temperature of 120 °C. Of course, the FML gas springs are approved as per the European Pressure Equipment Directive 97/23/EG.
Advantages of the FIBRO Mould Line series:
▶ Lower calibrating costs
▶ No lubrication required
▶ Maintenance-free up to 1,000,000 strokes1
▶ Force variably adjustable
▶ For mould temperatures of up to 120 °C
▶ Approved as per the European Pressure Equipment Directive 97/23/EG
▶ Standard safety features (FIBRO Safer Choice)2 Safety piston rod Excess pressure protection Overstroke protection
▶ By means of a pressure monitoring system, an impending failure can be recognised at an early point (prevention)
▶ No tool breakage, should the 2nd separation level lock (the plate comes to a standstill; after the removal of the jam, production can be resumed)
▶ Worldwide usage a million times over of FIBRO Gas Springs
▶ Cost savings: approximately 60-70% (e.g. compared to a latch-locking unit)

Flexible guides: The Flex GuideTM System
The Flex GuideTM System is a flexible guide in the gas spring which absorbs lateral movements of the piston rod. It minimises friction and lowers the operating temperature.
The benefits are:
• Extended service life• Increased stroke frequency, i.e. more strokes per
minute
Safe hose connections: The Dual SealTM System
The FIBRO Dual SealTM System combines a metal seal with a soft elastomer seal. On hose connec-tion systems, the system provides two leak-tight connections and prevents rotation.
The benefits are:
• Leak-tight connection, even under vibrations• High process reliability• Minimised tool down time• Simple installation thanks to anti-rotation
function
Wireless monitoring: The Wireless Pressure Monitoring (WPM) System
The optional Wireless Pressure Monitoring System (WPM) (patent pending) wirelessly monitors the pressure and temperature of FIBRO gas springs. Before a defective part is produced, the press operator receives a message from the WPM and can take appropriate action.
The benefits are:
• Preventative quality assurance• High process reliability• Minimised tool down time• Reduced maintenance and costsPotential faults are individually displayed. As a result, service intervals can be extended. Maintenance and repair costs are reduced.
Protected piston rods: FIBRO Concertina Shrouds
The FIBRO Piston Rod Protection (patent pending) reliably protects the piston rods in gas springs against dirt, oil and emulsion. In this way, the system prevents damage to the piston rod surface and leaks at internal seals.
The benefit is:
• Significantly longer service life for gas springs under harsh operating conditions
Energy saving: Gas spring DS
The Gas Spring DS will not be displaced by every stroke of the top tool. This saves the energy expenditure of the press for the whole stroke of the spring.
The benefits are:
• Significantly longer service life for the gas spring• Minimised tool down time due to reduced wear• Up to 70-80% less energy than "conventional"
standard gas springs for tool spacing.• Reduced maintenance and costs

At FIBRO, safety and reliability are paramount. Particularly when it comes to our gas springs. With their unique range of safety features, FIBRO gas springs are the safest on the market.

9 7 / 2 3 / E C
for 2 Million strokes
PED approval for 2 million strokesFIBRO gas springs are developed, manufactured and tested for a minimum of 2 million* full strokes in accordance with DGRL97/23/EG. The springs deliver this full performance at the maximum permissible limits in terms of filling pressure and operating temperature - even when combined with any of the various mounting types available.* Calculation value for durabilityThe benefit is:• Guaranteed safety and reliability for the entire service life
of the spring. Repair kits and qualified training sessions available through FIBRO Service offer increased effectiveness and process reliability.
Overstroke protectionConventional gas springs can burst in the event of an over-extended stroke. If this happens, parts flying around can become dangerous projectiles.FIBRO gas springs are different: in the event of an overstroke and depending on the spring type the patented protection system will ensure that either the cylinder wall of the gas spring is deformed in a predefined manner or the piston rod destroys a rupture bolt in the floor of the cylinder, thereby allowing the gas to escape into the atmosphere.The benefit is:• No risk of parts flying around in the event of an overstroke.Possible causes of triggering:Lack of stroke limitations in the tool/machine and placing the piston rods under a load (e.g. sheet-metal holder, slide reset, etc.), double sheet, incorrect installation position, etc.
Return stroke protectionA particularly dangerous situation can arise with conventio-nal gas springs if tool components become jammed and the pressure on the compressed piston rod is then abruptly released: in this case, the piston rod is then fired out of the cylinder like a missile.FIBRO gas springs are different: special guides and a patented safety stop in the piston rods ensure your safety. If the speed is too high during the return stroke, the collar on the piston rod will automatically break. The integrated safety stop then destroys the seal, which allows the gas to escape into the atmosphere and the gas spring to become depressurised.The benefit is:• No risk of a piston rod firing out if the return stroke is too
fast.Possible causes of triggering:Sudden loosening of jammed components, such as sheet-metal holder, slide, ejector, scraper function, etc.
Overpressure protectionConventional gas springs can burst if the internal pressure rises above a maximum permitted value. If this happens, parts flying around can become dangerous projectiles.FIBRO gas springs are different: if the pressure rises above the maximum permitted value, the safety collar on the sealing set is automatically destroyed. The gas then escapes into the atmosphere and the gas spring is depressurised.The benefit is:• No risk of bursting parts in the event of overpressurePossible causes of triggering:Incorrect filling (max. filling pressure 150 or 180 bar, nitrogen), infeed of liquid operating material, etc.
