COOLING DEMANDS IN THE PLASTIC INDUSTRY

In plastic production, a significant amount of heat is generated. Critical points that require strict temperature control include:

• Injection molds: Mold temperature directly affects cooling time, product precision, and surface quality.

• Extrusion and blow molding machines: Require continuous cooling to ensure melted plastic is evenly cooled.

• Plastic pelletizing and recycling: Need to cool large volumes of molten plastic effectively.

Without a specialized cooling system, manufacturers may encounter product warpage, surface defects, equipment overload, or higher energy bills. This is why chillers have become the top choice in the plastic industry.

CHILLERS – THE OPTIMAL COOLING SOLUTION FOR THE PLASTIC INDUSTRY

A chiller is a dedicated device that cools water and circulates it through molds, extruders, or other equipment requiring heat removal.

Currently, there are two common types of chillers used in the plastic industry:

• Water-cooled chillers: Use a cooling tower to dissipate heat into the environment. Advantages include high efficiency, suitable for large-scale factories.

• Air-cooled chillers: Use fans to cool the condenser. Advantages include compact size, easy installation, no need for a cooling tower—ideal for small and medium-sized facilities.

Both types are widely applied in injection molding, extrusion, blow molding, and pelletizing, offering benefits such as:

• Stable product quality.

• Shorter production cycle time.

• Extended equipment lifespan.

• Reduced risk of unexpected downtime.

DC INVERTER TECHNOLOGY – ENERGY-SAVING COOLING SOLUTION FOR THE PLASTIC INDUSTRY

Beyond traditional chillers, a rising trend in the plastic industry is the DC Inverter chiller. This advanced technology uses a DC variable-speed compressor that adjusts cooling capacity flexibly based on actual load.

Key advantages of DC Inverter chillers:

• Save 30–40% energy compared to conventional chillers.

• Smooth start-up, reducing electrical shock and protecting the plant’s power system.

• Maintain stable temperatures with minimal fluctuation.

• Longer equipment lifespan thanks to load-based operation instead of continuous “full load” running.

Since plastic manufacturing often operates 24/7 with fluctuating cooling demands depending on shifts, adopting a DC Inverter chiller helps businesses significantly cut energy costs while ensuring stable and reliable operation.
