PET bottle in production process, raw material after formed by melting, injection molding, blow molding of three step process.In order to ensure the smooth undergoing of the three main links need to be on the material pretreatment.
Material by dehumidifier drying before melting, dust removal by molecular network, tropical preheating, in order to material melt even, without impurities, injection molding products do not contain bubbles.
Material before injection also need by the injection pressure increase first and then into the cavity, ensure material in the process of forming dense.
After three before blowing the work steps to ensure that the bottle preform in the process of blow molding the good gas heating of knife;Heating process of roll ring spinning, in order to make the bottle preform heated evenly.In advance before blow molding need to put a beat, made just heated preform a heat evenly.
In order to meet the requirements of the above, automated continuous process, need to industrial computer control step drying, pressure, heating and other workers work together, work must beat united everywhere.
For the required heating is through in extrusion machine pipeline wall above Settings and tropical heating step by step to complete, make the material in the pipeline forward while plasticizing gradually.
Apertures net is set up so that materials can be according to the extrusion machine mouth.Extrusion machine is connected with a gun in the mouth.Material into the injection molding cavity first and then the gun switch direction are connected to the injection mold sprue, injection gun booster, the start of the single hydraulic cylinder under the action of the material into the cavity.
In the heating, rotation is set up to adjust station to complete the job.Adjust the station coordinate rotation speed and heating time, so that bottle of billet heated evenly.Adjust station control turned on or off by the main electric cabinet, moreover adjust station through its own electric cabinet coordinated action.
Blow molding is at the bottom of bottle production process, the main action here for blowing bottle embryo, embryo bottle expansion, expansion restricted by mold, final setting.Need to finish the mould clamping, sealing, stretching, three blows, deflated, open mode of eight major step.
