Fully automatic PET blow molding machine designed and produced by Demark Machinery has 4 kinds :DMK-R series high speed rotary fully automatic blow moulding machine, SFL series servo energy saving fully automatic blow molding machine, normal economical DMK-L series linear blow molding machine, big bottle series fully automatic blow molding machine. Adopting the European world leading technology for bottle blowing machine.
Demark Machinery is specialized in PET preform molds, PET LINE and blowing molds. It is one of the earliest companies adopting needle valve hot runner system. We offer preform molds and PET Line under 144 cavities. We can also take the project for the remake of injection molds for the famous international and domestic companies, such as offering cold half part, hot runner, the core, the cavity and screw. Our blowing molds can not only be equipped with our bottle blowing machine, but also be equipped with other famous blow molding machine such as SIDEL,KORONES,SIPA,SIG and ASB. We are one of the few domestic companies whose products can take place of imported PET injection molds and rotary blowing molds.
For the present, we have a powerful team with high technology: about 20 engineers specialized in machine and mold design, about 30 special designers and about 160 technicians specialized in machine and preform manufacturing for more than 10 years. Collecting the essence of PET packaging machinery and mold industry, the automatic, hommization design is greatly convenient to the users, with high productivity, good assurance for excellent efficiency and high cost performance. The powerful team assures our products with advanced technology, reliable quality, for gaining high reputation and good credit.

Technical Description Of Main Equipment
Brief Introduction
Fully-Automatic Big Volume Linear PET Stretch Bottle Blowing Machines.
SBL Series As a pioneer in manufacturing the full-automatic linear PET stretch blow molding machine especially for the big volume bottles, Demark adopts special design on the preheat construction and servo driving system to enable it big volume blow molding machine series save more than 50%power compared with similar machines by others.
SBL Series is available for blowing bottles for beverage, edible oil, catchup, cleaner, cosmetic and medical products with the volume between 5L and 20L
2 highlights:
Good stability: thanks to the excellent design concept and strict machining request as well as the outstanding electric collocation.
Competitive price: provide machine with good quality while lower price.
3 characters:
Demark Machinery bring in the method of rotary blowing mould machine to develop linear blowing mould machine for the first time among the domestic manufacturers, which has resolved the problems of bad stability and low efficiency of traditional linear blowing mould machine.
Jeepine Machinery is the first company that makes the single cavity capacity up to 600 bottles per hour (take 20L Oil bottle for example).
Peculiar heating system of light bar and light box with special design make it saving electric power by 50%.
4. innovations:
Blowing system: cooperate with the international leading research organizations; create the high-pressure integration valve group, the single cavity productive capacity is increased by 60%.
Heating system: patent light box provides constant and circulatory temperature(heater is fixed with short linkage 101mm, much shorter than 240mm), to save electric power by more than 50%;accurate control on the position and speed by servo, assure the action of the preheating-chain and manipulator in synchrony.
Stretching system: use linear sliding track framework instead of liner bearing, which offers an outstanding improvement of stability.
Main transmission system: adopt patent double strand roller chains technology, to assure the demands of stability and high speed.
Hydraulic pressure close mold system: take the place of traditional pneumatic die set, with both sides pressure and four boards forming, assure the stability an the pass rate of 99.8%.
Manipulator system:adopt servo controlling manipulator to keep the action of perform-sending and bottle-taking in synchrony, accurate and fast
