The annual meeting of the China Plastics Processing Industry Association (CPPIA) was held on June 17 2023 in Zhangjiagang, focusing on reducing the carbon footprint, a key element for the environmental footprint of goods and services.

This event highlighted how industrial activities contribute to global warming and discussed strategies to mitigate these impacts.

ST BlowMoulding participated as a speaker, illustrating how blowmoulding technology can significantly contribute to reducing the environmental footprint.

The highlights of the presentation were the following:

Reduction of Energy Consumption.

ST BlowMoulding machines are equipped with a lot of features designed to reduce energy consumption:

-thermal insulation of the plasticizing units which helps to keep the temperature constant, reducing the need for additional energy for heating;

-synchronous reluctance motors for extruders, which are more energy efficient;

-variable speed hydraulic pumps that allow to use only the necessary energy, adapting to operational needs;

-the"adiabatic" extruders that minimize heat loss, improving energy efficiency.

Reduction in the consumption of raw materials.

Reducing the weight of blowed items is crucial to minimizing the use of raw materials.

The high resolution of the parison thickness profiles allows precise control of the material thickness during extrusion, making the item lighter.

Radial control of the parison thickness ensures process uniformity and stability.

The reduction of the rejects (NOK Parts).

Sound machine design and manufacturing are critical to process stability and reducing the rejects (NOK Parts).

Key elements are technical skills and adequate materials, accurate production and selected components, powerful software.

A world-class blowmolding machine, such as those offered by ST BlowMoulding, can significantly contribute to reducing the carbon footprint compared to machines with lower technology.

The adoption of such advanced technologies is essential to address current and future environmental challenges, promoting a more sustainable and responsible industry.
