| | Description： | Comparing with other conventional toggle molding machine, our fully
hydraulic four-cylinder structure has the advantages such as much
more precise, no mechanical abrasion, longevity of service, fast,
high efficiency, energy saving, and no need to adjust the mold and
no need oil lubrication. Detail is as following,
1. Our machine has extremely long guide(as 4 times as the
conventional toggle machine), uniform distribution of clamping
force(precision is up to 0.3%) will keep the machine in a smooth
motion, so the bottle preform eccentricity can be improved
effectively.
2. Our machine does not need mold adjust and oil lubrication, so
the machine is highly clean and tidy as required by the sanitary
standard by food and drinking products, it is a completely purified
workshop!
3. Uniform clamping force, best repeatability precision and
professional PET injection screw will increase the stable quality
and ensure the yield.
4. Clamping force and injection pressure can be self adopted each
other automatically by a feedback control system, i.e, the clamping
force declines with the end of injection. This function will keep
the mold away from heavy load for a long time as well as save
energy. The maintainance frequency of the mold will reduce more
then 50% whereas the longevity will increase over 50%.
5. Sensitive and reliable low-pressure mold protection
function(precision 0.1mm) will keep the mold in safe effectively if
any accident happens.
6. During the cooling stage, the clamping force will fall to zero
as the injection pressure fall to zero before the mold opened, so
the opening impact and shake can be avoided; the internal stress
can be eliminated effectively and the opening fracture on the
bottle-neck will be prevented.
7. PET bottle preform is a semi-finished article. Its molding
precedure needs the best repeatable precision in order to keep the
preform to be molded under the same condition and ensure the inner
parameters to be uniform. The best yield on the said condition will
become a stable technical base for fully automatic blowing
procedure. |
