Adjust its height, the cooling plate, etc. is important to make the oven work better. When adjusted properly, prone to swelling during blow bottle (bottle larger) hard head and neck (neck material will not pull out) and other defects. 2.3 pre-blow
Refers to the stretch blow molding process in the pre-start lever is declining blowing, pre-blowing is a two-step blow molding method is a very important step. Begun to take shape make preforms. This step is a pre-blow position, pre-blowing pressure and gas flow rate are three important technological factors.
Abnormal there are sub-bell-like, handle shape. Causes abnormal shape undue local heating, the shape of the merits of pre-determined blowing ease and bottle blow molding process of the merits of the performance. Pre-blowing normal spindle shape. Pre-blowing pressure or blowing insufficient flow, etc., and the pre-blowing depends on the size of the pre-blow pressure and pre-blow position. Production of the entire equipment to maintain all pre-blowing uniform size and shape, if the difference will have to look for specific reasons, can adjust the heating or pre-blow process according to the pre-blowing situation.
General capacity, pre-blowing pressure to be small; equipment production capacity, with the size of the pre-blow pressure bottle size, device capabilities vary. Pre-blowing pressure is high.
PET materials due to differences in performance, even when using the same equipment in the same standard bottles. It requires pre-blow pressure are not the same. Glass fiber reinforced PET data, the smaller pre-blowing pressure so that the bottom of the bottle to the correct orientation of macromolecules; improper or inappropriate preform molding process other materials, there is a lot of stress near the injection point of focus is not easy to subside, if Blow, blow often broken or burst from the injection point in the stress test, the leakage at the injection point. According to the orientation of the conditions, then you can, as shown on the tube is removed 2-3 branch to open over the injection point, given injection point is sufficiently heated to provide enough heat to facilitate their rapid orientation.
