Three Common Misconceptions When Selecting Industrial Chillers!

In your injection molding shop, have you ever thought: "I just need a chiller with roughly the right cooling capacity for this machine," or "As long as it cools, it should be fine"?

If so, your operation might be silently suffering from efficiency losses, rising costs, and quality inconsistencies. Today, we're debunking the myths and discussing the three most common misconceptions when selecting a chiller for an injection molding machine. Understanding these is the first step toward reducing costs and improving efficiency.

Misconception 1: Cooling Capacity – "Close Enough is Good Enough"

This is the most classic and costly misconception. Many customers simply provide an injection machine's tonnage and ask for "a chiller that's about right."

The Science Explained:
Determining the required cooling capacity is not as simple as matching it to the machine's size. It's a scientific calculation based on material type, product weight, cycle time, and other factors. For instance, the thermal load for processing PC is entirely different from PP; a 500-gram part and a 50-gram part require vastly different cooling capabilities.

The Consequences of "Close Enough":
An undersized chiller is like using a small horse to pull a heavy cart. It must run at full power constantly, leading to:
Longer cooling times, slower production cycles, and reduced overall output.
Inability to reach the set temperature, causing defects like shrinkage and warpage.
Shortened chiller lifespan and frequent breakdowns due to constant overloading.

The LESINTOR Solution:
At LESINTOR, we never recommend a "close enough" model. Our technical consultants perform professional heat load calculations based on your specific production process. We recommend a unit with more than adequate cooling capacity, ensuring it operates within its most efficient range. This guarantees optimal performance and extends the equipment's service life.

Misconception 2: Temperature Control – "As Long as it Cools"

Some users believe a chiller's job is done as long as the water temperature drops. However, the precision and stability of temperature control are what truly determine product quality.

The Science Explained:
Temperature fluctuations in the mold are directly transferred to the product. Imagine the mold temperature fluctuating like an unstable heartbeat—the crystallization rate and molecular orientation of the plastic will vary accordingly.

The Consequences of "As Long as it Cools":
Increased internal stress in products, leading to warping and deformation later—a critical failure in precision molding.
Poor dimensional stability, with significant variations between batches, making consistent high yield rates impossible.
Surface defects like splay marks and inconsistent gloss.

The LESINTOR Solution:
LESINTOR industrial chillers feature an advanced PID intelligent temperature control system. It acts like an experienced helmsman, performing proportional-integral-derivative calculations and anticipatory adjustments to maintain temperature within an extremely narrow range of ±1°C or even ±0.5°C. This provides a mold environment as precise and stable as a "Swiss watch," eliminating quality risks caused by temperature fluctuations at their root.

Misconception 3: The Water Pump – "It's Not Important"

When focusing on major components like the compressor and condenser, the water pump—the core power unit—is often overlooked. Many don't understand the importance of pump head (pressure) and flow.

The Science Explained:
Think of it as the chiller's "heart." Flow rate determines the volume of coolant circulated per unit of time, while head represents the pump's "push" or ability to overcome resistance in the plumbing system.

The Consequences of an Incorrect Pump:
Insufficient Flow: Not enough coolant passes through the mold's cooling channels, leading to low heat exchange efficiency and poor cooling.
Insufficient Head: The coolant cannot be effectively pushed to the highest points or through complex circuits in the mold, creating significant temperature differences across the mold and uneven part cooling.

The LESINTOR Advantage:
LESINTOR chillers come standard with high-flow, high-head industrial water pumps, precisely matched to the unit's capacity. We ensure a powerful and stable water circulation that penetrates every complex mold channel, achieving uniform and efficient cooling. This keeps your mold's "circulation system healthy" and your product quality consistent.
