Innovations

Heating system
Patent light box provides constant and circulatory temperature (heater is fixed with short linkage 101mm, mach 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 manipullator in synchrony.

Hydraulic pressure close mold system
Take the place of traditional pneumatic die set, with both sides pressure and four boards forming, assure the stability at the pass rate of 99.8%.

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%.

Stretching system
Use linear sliding track frame work instead of linear 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.

Manipulator system
Adopt servo manipulator to take the preform and bottles synchronously, accurately and quickly.

Highlights of SBL series blower

• 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.
• Demark 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 lowefficiency of traditional linear blowing mould machine.
