Why Use Neybo Preheaters?

Whether you are dispensing adhesives, coatings, or sealants, preheating your material to the right temperature is critical for a secure process.

Here are the five primary reasons why integrating Neybo Preheaters into your workflow optimizes efficiency and product quality.

1. Lowering Viscosity

One of the most common production challenges is handling cold, thick materials. High viscosity creates excessive drag within your system.

The Challenge: When material is cold and viscous, feed pumps must generate extreme pressure to move the fluid. This leads to:

• High wear and tear on seals and pumps.
• Uneven distribution or “spitting” at the nozzle.
• Increased energy consumption by pump motors.

The Solution using Neybo Heaters: Preheating is the most efficient way to lower viscosity. By warming the fluid, it flows effortlessly through the system. This reduces back-pressure, extends the lifespan of your pumping equipment, and ensures a finer spray pattern or precision bead application.

2. Improving Wetting and Surface Adhesion

Even the strongest adhesive will fail if it cannot make intimate contact with the substrate surface.

The Challenge: Cold adhesives or paints often exhibit high surface tension. They merely “float” on top of the substrate rather than penetrating microscopic pores. This results in poor bonding and a high risk of detachment after curing.

The Solution using Neybo Heaters: Heat significantly reduces surface tension. This allows the material to “wet out” properly and creep deep into the surface structure. The result is a mechanical anchor that guarantees maximum adhesion strength.

3. Accelerating Reaction and Curing Times

In high-volume manufacturing, time is money. Waiting for chemical reactions to complete at ambient temperatures creates bottlenecks.

The Challenge: Chemical curing is often sluggish at room temperature. Finished parts require long storage times (WIP) before they are solid enough to handle, wasting valuable floor space and slowing down total throughput.

The Solution using Neybo Heaters: Heat acts as a powerful catalyst. Following the Arrhenius equation, a modest increase in temperature can double reaction rates. Neybo heaters reduce curing time, enabling faster cycle times and allowing parts to move to the next production stage immediately.

4. Degassing for Bubble-Free Finishes

Trapped air is a major cause of scrapped parts in casting and potting applications.

The Challenge: In viscous masses, air bubbles introduced during mixing or dispensing remain trapped. This leads to:

• Visual defects (pinholes) in paints and coatings.
• Electrical breakdowns in potting or insulation compounds.
• Structural weaknesses in composite parts.

The Solution using Neybo Heaters: By warming the material to lower its viscosity, resistance against rising bubbles is reduced. Air escapes quickly to the surface and bursts before the material cures, ensuring a void-free, high-quality finish.

5. Ensuring Seasonal Process Stability

Manufacturing environments are rarely perfectly climate-controlled, leading to inconsistencies known as “Winter/Summer Syndrome.”

The Challenge: Material stored in a warehouse is significantly colder in January than in August. These temperature fluctuations cause process parameters to drift, leading to inexplicable failures or variations in dispensing amounts despite unchanged machine settings.

The Solution using Neybo Heaters: By actively preheating to a defined setpoint (e.g., 40 °C / 104 °F), you create a consistent thermal baseline regardless of the ambient weather. Your process performance in winter becomes identical to your performance in summer, eliminating seasonal variables.
