DME NITROGEN GAS SPRING
All DME products are accurately manufactured with equipments of high precision
such as CNC, M/C, etc., and have passed several trial tests of over one million
strokes under SPM80 condition. DME looks forward to a big contribution
to the die set industry by developing the TSP series which is compacter than
existing gas springs.
Quality Assurance
DME gas springs come with a two-year warranty from date of shipping from
the warehouse or one million strokes. Every troubleshooting service and (or)
exchange of parts during this term is free. Also, should any critical defects arise
after the two-year guarantee period, the products shall be replaced free of
charge.
Maintenance
DME gas springs are manufactured based on a simple structure , which requires
no repairthroughout their lifetime. DME gas springs that are damaged
during operations after use can be easily repaired by simply replacing the
damaged parts . In addition, adequate load can be specified by directly adjusting
the pressure on site.
Fast Delivery
In order to ensure fast deliveries and support parts for A/S, DME is equipped
with requirements such as procurements of load testing facilities , gas charging
facilities and a comprehensiveinventory for all spare parts. We also carry
sufficient stock for certain models to minimize lead-timeand to reduce deadlock
in production. Models that are out of stock can be delivered within 7 days.
However, this lead-time varies according to quantity and location.
Notice
• Although there is a tap of M6 or M8 on top of the piston rod for assembly and a
disassembly, this should not be used to fix the gas springs or for any connecting
devices.
• During the installation, please ensure that there is about 1mm of margin space
between the contact surface and the upper part of the piston rods, Also, there
is no need for pre - pressure because the initial pressure is strong enough. Any
increase of pre-pressure can damage the molds.
• DME gas springs must be used as is. Do not cut or grind the upper part of the
piston rods or grind the lower part of the gas springs, as it is dangerous. Any
change on the gas spring can shorten its life and cause a malfunction.
• When installing the springs, please ensure that the bottom surface of the
springs touch the mold to absorb the load of gas spring. However, when assembling
with mounts, there should be space between the mount and the
bottom surface of the mold. This is to prevent the mold from breaking should
heavy load breaks the mount.
