Our Advantages
6 innovations:
1.Blowing system: cooperate with the international leading research organizations; create thehigh-pressure integration valve group the single cavity productive capacity is increased by 60%.
2.Heating system: patent light box provides constant and circulatory temperature(heater is fixed with short linkage 101mmmuch 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.
3.Stretching system:use linear sliding trackframeworkinstead of liner bearing,which offers an outstanding improvement of stability.
4.Main transmission system: adopt patent double strand roller chains technology to assure the demands of stability and high speed.
5.Hydraulic pressure close mould 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%.
6.Manipulator system: adopt servo controlling manipulator to keep the action of perform-sending and bottle-taking in synchrony, accurate and fast.
Product Description
working process
1 Preform Feeding :Preforms are fed by star-wheel to load onto chain spindles continuously.
2 Preform Heating :During heating, the preforms are constantly rotated for a perfectlysymmetrical distribution of heat. The necks of the preform are protectedfrom oven-heating by means of protection ramp with cold water.
3\4 Pitch Changeover :After heating,the preforms go into pitch-change by servo motorBy slider, the abutting preform's center distance changes from50.8mm to mold's center distance.
5 Stretching & Blowing :After pitch changeover, the preforms are sent into the mold, The longitudinalstretching of the preform is carried out by a servo motor, then is pre-blow,nigh-pressure blow and exhaust.
6 Bottle Discharging :The blown bottles are removed from the molds by servo motor, and be evacuatedeither in bulk or directly feed to the filling lines via sucking conveyor.
