ChangdeMold air ring and IBC internal cooling control

Utilizing Taiwanese molds, its runner design, operating principle, and material‑feeding distribution demonstrably outperform the conventional bottom‑feed or outer‑side‑feed technologies currently employed in the industry.

Product Description

1. Utilizing Taiwanese molds with a state-of-the-art runner design, advanced operating principles, and optimized material distribution, this system significantly outperforms conventional bottom‑feed or outer‑side‑feed technologies currently employed in the industry. It reduces resin holdup in the die by approximately 30%, enabling faster and higher‑speed resin switching, accommodating a wide range of resins, and offering greater flexibility even when processing high‑viscosity materials. For example, when transitioning from LDPE to an LDPE:LLDPE blend ratio of 1:5, the changeover time is approximately 10 minutes.
2. Equipped with a Taiwan‑made air ring, this high‑precision, low‑resistance, high‑flow cooling air ring delivers exceptional film‑blowing airflow, ensuring stability and excellent cooling performance.
3. The IBC’s uniquely designed cooling air duct differs from the conventional in‑house exhaust systems used by domestic competitors, which position the intake system directly adjacent to the die head, resulting in rapid die‑head cooling but making internal heating more challenging. This more scientifically engineered system is better suited to quickly switch between products of varying wall thicknesses and formulations, delivering superior surface finish, transparency, and plasticization performance.
4. High production capacity: under normal operating conditions, it produces 250 kg/h, and with refrigeration enabled, the air quality is further improved.
5. An optional automatic online thickness‑control system is available, enabling product uniformity within ±3% to ±5%.
