RELIABLE BOTTLE BLOWING MACHINE

Part 1 Principle

The blowing process of the blow molding machine is divided into two parts

1. Warm up

The preform is irradiated by an infrared high-temperature lamp tube to heat and soften the part of the preform of the preform. In order to maintain the shape of the preform, the preform does not need to be heated, so a certain cooling device is needed to cool it.

2. Blow molding

At this stage, the preheated preforms are placed in the blow molds that have been prepared, and high-pressure inflation is performed in them. Blow the preform into the desired bottle.

The automatic blow molding machine combines the two operations of blowing the bottle through the operation of the manipulator, eliminating the process of manually putting the preheated preform into the blow mold in the middle. Greatly speed up the production rate.

Part 2 Technological process of the bottle blowing machine

The blow molding process of the bottle blowing machine is a two-way stretching process. In this process, the PET chain is extended, oriented and arranged in two directions, thereby increasing the mechanical properties of the bottle wall and improving the stretching, tensile and impact resistance. Strength, and has good air tightness. Although stretching helps to increase the strength, it cannot be overstretched. It is necessary to control the stretch inflation ratio: the radial direction should not exceed 3.5~4.2, the axial direction should not exceed 2.8~3.1. The wall thickness of the preform should not exceed 4.5 mm.

Bottle blowing is carried out between the glass transition temperature and the crystallization temperature, generally controlled between 90 ~ 120 degrees. In this interval, PET is highly elastic, blows quickly, and becomes a transparent bottle after cooling and shaping. In the one-step method, this temperature is determined by the length of the cooling time during the injection molding process, so it is necessary to connect the relationship between the injection and blowing two stations.

During rapid blow molding and cooling, induced stress is generated in the bottle wall. For aerated beverage bottles, it can resist internal pressure, which is good, but for hot-filled bottles, it is necessary to ensure that it is fully released above the glass transition temperature.

Blow-molded PET bottles are mainly used in five major fields: beverages, dairy products, alcohol, condiments and cosmetics. With the brand image of leading companies in the industry, advanced system solutions, and elaborate manufacturing levels , Standardize strong engineering capabilities and well-known after-sales service, have won the trust and recognition of domestic and foreign brand manufacturers, and established extensive and intimate cooperation with domestic and foreign famous beverage factories.
