1. Preheating
The bottle preform is heated using infrared high-temperature lamps to soften its body. To maintain the shape of the bottle neck, the neck area is not heated. Therefore, a cooling system is required to keep it at a stable temperature.
2. Bottle Blowing and Molding
In this stage, the preheated bottle preform is placed into a pre-made blow mold. High-pressure air is then introduced into the preform, expanding and stretching it into the desired bottle shape.
Blow molding machines on the market are generally divided into two types: fully automatic and semi-automatic.
Fully automatic blow molding machines integrate both the preheating and bottle blowing processes using robotic arms, eliminating the need for manual placement of preheated preforms into the mold. This significantly increases production efficiency but comes at a higher cost compared to semi-automatic machines.
Product Selection
Choosing the right bottle blowing machine model is undoubtedly a key concern for many.
Generally, the selection of a blow molding machine should be based on the specific product requirements. Manufacturers with different production needs usually focus on factors such as the number of cavities per cycle, the bottle capacity, and the hourly production output.
Selecting a model that aligns with your production demands is essential for achieving optimal efficiency and cost-effectiveness.
