Comparing with other conventional toggle molding machine, our fullyhydraulic four-cylinder structure has the advantages such as muchmore precise, no mechanical abrasion, longevity of service, fast,high efficiency, energy saving, and no need to adjust the mold andno need oil lubrication. Detail is as following,

1. Our machine has extremely long guide(as 4 times as theconventional toggle machine), uniform distribution of clampingforce(precision is up to 0.3%) will keep the machine in a smoothmotion, so the bottle preform eccentricity can be improvedeffectively.

2. Our machine does not need mold adjust and oil lubrication,so the machine is highly clean and tidy as required by the sanitarystandard by food and drinking products, it is a completely purifiedworkshop!

3. Uniform clamping force, best repeatability precision andprofessional PET injection screw will increase the stable qualityand ensure the yield.

4. Clamping force and injection pressure can be self adoptedeach other automatically by a feedback control system, i.e, theclamping force declines with the end of injection. This functionwill keep the mold away from heavy load for a long time as well assave energy. The maintainance frequency of the mold will reducemore then 50% whereas the longevity will increase over50%.

5. Sensitive and reliable low-pressure mold protectionfunction(precision 0.1mm) will keep the mold in safe effectively ifany accident happens.

6. During the cooling stage, the clamping force will fall tozero as the injection pressure fall to zero before the mold opened,so the opening impact and shake can be avoided; the internal stresscan be eliminated effectively and the opening fracture on thebottle-neck will be prevented.

7. PET bottle preform is a semi-finished article. Its moldingprecedure needs the best repeatable precision in order to keep thepreform to be molded under the same condition and ensure the innerparameters to be uniform. The best yield on the said condition willbecome a stable technical base for fully automatic blowingprocedure.
