We often use bottle making machine to produce various specifications, various styles of glass bottles. In actual production, the speed of the equipment to process glass bottles is not the same, there are fast and slow, then, what factors affect the processing speed of the equipment?

1. Preforms

Preforms, also known as type blanks, PET granules by injection molding, injection molding of preforms or heated preforms reused preforms cooled more than 48h, and the use of preforms can not be more than 6 months of storage time, different consumption dates, especially the distance is too long preforms can not be mixed, the main reason is that the preforms used in the raw material type, mixed into the proportion of the secondary material and preforms within the residual stress is caused by the different elements of the bottle making machine molding process. Bottle making machine molding process has a serious impact, should be based on the practical situation in detail.

2.Heating

The heating of the preform is done by the heating furnace, which is set manually and adjusted automatically. The height of the heating furnace in 25mm or so appropriate, from the feed wheel 19.6mm or so. But the heating furnace, such as improper adjustment, will form the blowing bottle wall thickness unevenly distributed up and down (such as light on the bottom), the bottle mouth becomes larger than the standard, hard neck and other product defects, and even the formation of mechanical parts of the torsion problem.

3. Pre-blowing

The role of pre-blowing in the blowing process is to make the initial shape of the preform, and at the same time by the longitudinal stretching rod to increase its longitudinal strength. The whole process is pre-blowing cam in the blowing process to push the three-way valve to the pre-blowing position, and the check valve with the completion. The pre-blowing position, pressure and flow rate can affect the quality of the bottle.

4. Stretching lever

Stretching rod is in the pre-blow with the pre-blow at the same time the heated preform stretching device, it is in the high-pressure blowing, exhaust before reset. Tension rod in the bottle making machine blowing process can be up and down vertical smooth movement, driving pressure of 0.55-0.8MPa, and the bottom of the mold clearance of 2.3-2.5mm, that is, the thickness of the preform 1/3-1/2. clearance is too large, the formation of the bottom of the bottle center offset; clearance is too small, the center of the thinning.

5. High-pressure blowing

The role of high-pressure blowing is to make the melt is fully extended, close to the mold wall, so that the bottle is fully formed, while stopping the transverse stretching, to improve its transverse strength. The main factors affecting the position and pressure.

6. Mold

Mold is one of the important elements affecting the bottle blowing into shape. Bottle body for haf mold, bottle bottom independent, is a typical blow mold. Consumption process, to adhere to the mold constant temperature, clean, exhaust holes. Mold heating, cooling system presents a problem, it will present bottle neck crooked, bottle tilt, volume, height change, the bottom becomes heavy and other defects; Maintaining constant temperature of the mold can also avoid mold condensation on the outside.

Bottle making machine blowing process is if by the above six factors, we use the equipment to produce glass bottles in accordance with the relevant requirements for the operation, the processing process, but also pay attention to the above points, so that it is highly efficient to complete the processing of glass bottles.
