Recently, the “Laser Precision Heating Bottle Preform Intelligent Equipment” independently developed by HGTECH successfully passed the bottle-blowing test in Hangzhou, achieving a domestic first in this field.
With the green and low-carbon transformation of the manufacturing industry, the traditional PET preform production industry is facing dual challenges: technological advancement and environmental compliance requirements.
In the packaging industry, a large number of plastic bottles are typically required for filling. The blow molding process, due to its simple procedure and low cost, has become the primary method for plastic bottle production. In a plastic bottle blow molding production line, the preforms need to be heated to a certain temperature before being blown into plastic bottles. The quality of processing during the preheating stage directly affects the quality of the finished plastic bottles.
Traditional heating methods commonly use infrared lamps to heat preforms, but several pain points are prevalent in actual production:
High energy consumption: The absorption rate of preforms to the broad spectrum of infrared lamps is low, resulting in significant energy loss during the heating process.
High process requirements: The equipment is sensitive to environmental humidity and temperature, requiring high skill levels from technicians and precise tuning of the process.
Low heating precision: The infrared lamps have a large heating range, making temperature control difficult and imprecise. The preform neck is prone to deformation due to excessive heat, and to avoid overheating at the neck, a separate cooling cycle is needed.
High production costs: The equipment has a large footprint and occupies significant space.
Unprocessed preforms
In response to the industry’s production pain points, HGTECH has independently developed core technologies such as laser precision heating for preforms, creating the country’s first laser precision heating bottle preform intelligent equipment. By utilizing advanced laser technology for precise heating of preforms, this innovation marks a domestic first in the field and introduces new applications to the plastic packaging industry. Its prospects include precise temperature control for preform heating, plastic bottle design, heating of non-standard preforms, and preform lightweight design, among others.
