A. Brief Introduction
SBL Series as a pioneer in manufacturing the fully automatic linear PET stretch blow moulding machine especially for big volume bottles. Demark adopts special design on the preheator construction to enable it big volume blow moulding 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.
B. 5 Innovations:
a). Blowing system: cooperate with the international leading research organizations; create the high-pressures integration valve group, the single cavity productive capacity is increased by 60%.
b). Heating system: paten light box provides constant and circulatory temperature(heator's fixed with shorter linkage) to save electric power by more than 50%.
c). Stretching system: use linear sliding track framework instead of liner bearing, which offers an outstanding improvement of stability.
d). Main transmission system: adopt paten double strand roller chains technology, to assure the demands of stability and high speed.
e). Hydraulic clamping system: take the place of traditional pneumatic die set, with both sides pressure and four boards forming, assure the stability and the pass rate of 99.8%.
