Injection Moulding:
During injection moulding, molten plastic is injected into a mould cavity at a precisely controlled temperature. Airtech's water chillers provide a consistent coolant flow, typically mould temperature ranging from 5°C to 90°C depending on the specific plastic resin being used. This precise temperature control is crucial for proper mould cooling, ensuring the plastic solidifies rapidly and achieves the desired dimensional accuracy and surface finish.
Blow Moulding:
Blow moulding utilizes heated air to inflate plastic preforms into hollow containers. Airtech's industrial chillers provide cool air for post-moulding processes, typically between 2°C and 10°C with up to 5 bar pressure. This rapid cooling solidifies the plastic container shape and prevents deformation.
Extrusion:
Extrusion involves forcing molten plastic through a die to create continuous profiles like films, sheets, pipes, and tubes. Airtech's water chillers maintain a consistent coolant flow for the die and calibrating bath, typically ranging from 0°C to 30°C depending on the specific plastic being extruded. Precise temperature control ensures the plastic cools and solidifies at a controlled rate, achieving the desired dimensional stability and product properties.
Plastic Processing Equipment:
Throughout the plastics manufacturing process, various auxiliary equipment like grinders, mixers, and dryers may require temperature control to prevent thermal degradation of the plastic material. Airtech offers a range of chiller capacities to cater to the specific cooling requirements of this equipment.
