Bottle Defect 6 The bottle’s bottom is far too thin making PET bottle by bottle blower moulder. Raise the temperature of the upper heating tubes.Ġ6.The speed of the stretching rod is too slow.The upper portion of the bottle’s inflation ratio is too low.The mold vent is too far away from the upper portion of the oven.The temperature in the oven’s upper part is too low.Bottle Defect 5 The bottle’s upper portion is too thick when using PET blow moulder machine Increase the inflation or stretching ratio.Ġ5.Adjust the blowing hole’s position and diameter.An uneven thickness of the embryonic tube wall or an uneven injection density.In the heating furnace, the PET preform does not rotate.The stretching or expansion ratios are too small or too low.The blowing holes are asymmetrical, with different diameters.The stretch rod is not in the center of the PET preform for several reasons.Bottle Defect 4 PET bottles with uneven wall thickness of PET bottle blow molder machine Check for any problems with the rotation of the PET preform or improve the heating conditions.Ġ4.Adjust the magnetic pole switch’s position.Increase the descending speed of the stretching rod or delay the blowing time.The injection density or wall thickness of the PET preform is uneven.The extension rod is angled away from the bottle axis’s center line.Bottle Defect 3 The nozzle is offset at the bottom of the PET bottle made by PET bottle blowing moulder. To raise the surface temperature of the PET preform, reduce the thickness of the PET preform or increase the outer cover of the heating device.Ġ3.Increase heating tempature or decrease the rotational speed.The thickness of the PET preform is too thick, and the heating and penetration are inadequate.PET preforms with uneven wall thickness.Bottle Defect 2 The PET bottle made by blow moulder has a pearly luster and is white in color. Improve PET preform quality, select materials, and increase raw material drynessĠ2.Reduce the amount of time it takes to heat up.The PET preform’s design isn’t appropriate.The injection PET preform is opaque in and of itself.Bottle Defect 1: Poor transparency of PET bottles from bottle blow moulder Or, if you want to directly raise your own technical problems, let us give the best blowing solution, or you can contact us at any time through the form below.Ġ1. Based on our more than 20 years of production experience, iBottling has summarized the following solution for your reference. Affected the success rate and efficiency of bottle blowing. Especially in blow moulding PET bottles, we often encounter various blowing problems. Although this kind of container looks very simple, it is very particular about its craftsmanship. Plastic products occupy a relatively large proportion of our lives, especially those large and small plastic packaging bottles, which are closely related to our daily lives. #blowmoulder #blowmolder #blowmouldingmachine #blowmoldingmachine #petbottleblowmoulder #petbottleblowmolder #blowmoldingmachine #blowmouldingmachine #ibottling
