The plastic and rubber manufacturing industry relies on high-heat processes such as extrusion, molding, and thermoforming. These methods generate substantial heat, which must be removed quickly and consistently to maintain product quality and equipment efficiency. This is where industrial glycol chillers—like the dependable systems offered at Genemco.com—come into play.
Glycol chillers provide precise, reliable temperature control across multiple stages of production, helping manufacturers reduce cycle times, improve consistency, and minimize waste. Let’s explore how they are used in the plastic and rubber industries.
The Role of Temperature Control in Plastic & Rubber Processing
From injection molding to rubber curing, thermal management is critical to:
-
Prevent material degradation
-
Maintain mold accuracy
-
Ensure consistent product quality
-
Protect sensitive equipment from overheating
Using a glycol-water mixture allows chillers to maintain low temperatures while avoiding freezing issues—ideal for systems that require cooling below 32°F or operate in colder environments.

Key Applications of Glycol Chillers in Plastic and Rubber Manufacturing
1. Injection Molding
Injection molding is one of the most common methods for producing plastic parts. Once molten plastic is injected into a mold, it must cool and solidify quickly. Glycol chillers help by:
-
Providing rapid, consistent cooling of the mold
-
Reducing cycle times and improving production efficiency
-
Enhancing surface finish and dimensional accuracy
Stable cooling minimizes warping, sink marks, and inconsistencies between production runs.

2. Extrusion and Thermoforming
In extrusion and thermoforming processes, molten plastic is shaped into sheets, pipes, or custom profiles. Chillers are used to:
-
Cool the extruded plastic as it exits the die
-
Maintain consistent product dimensions
-
Prevent deformation or stress cracking
In thermoforming, glycol chillers cool the forming molds to ensure proper setting of the plastic material.
3. Rubber Curing and Vulcanization
In rubber manufacturing, curing or vulcanization processes involve heating rubber compounds to induce chemical changes. After heating, the material must be cooled quickly and evenly to:
-
Set final properties of the rubber
-
Prevent surface defects or irregular curing
-
Maintain throughput in continuous operations
Glycol chillers provide uniform cooling for rubber molds, extruders, and conveyor belt systems, helping manufacturers improve quality and reduce scrap.
4. Hydraulic and Equipment Cooling
In addition to cooling molds and products, glycol chillers are often used to regulate the temperature of machinery itself. This includes:
-
Hydraulic oil cooling systems
-
Temperature control units (TCUs)
-
Rollers and presses used in calendaring or lamination
By protecting equipment from overheating, glycol chillers extend the life of machinery and reduce the risk of unplanned downtime.
