UV curing is a commonly used form of light curing because of its high energy, which allows for rapid curing at low expense and with minimal risk. UV curing technology has experienced rapid growth in recent years thanks to the new developments driven by the rising demand for sustainable curing solutions. There have been significant developments in UV curing; the process takes place within a short time of exposure.

This technology has not only transformed the printing sector but has also gained popularity in applications in different industries. But what exactly is this process about, and what role does it play in enhancing your business's output and environmental impact? Read on!

What Is UV Curing?

Think of this process as a process where manufacturers use light to change liquids to solids. This technology is everything manufacturers need for low temperature and time-saving. Its popularity in applications like printing and coating is unmatched compared to other curing methods. This technology improves the physical/chemical characteristics of polymeric materials for surface finishes and bonding.

How Does UV Curing Work?

UV curing chemical processes use photo-initiators distributed inside adhesives like ink, coatings, and extrusion formulas. Photo-initiators collect UV energy when in contact with light wavelengths ranging from 100-450 nm, creating cationic species or free radicals.

The activated molecules initiate, propagate, and terminate actions, rapidly modifying the structure of molecules of the unprocessed elements. UV curing applications primarily involve radical curing processes with cationic uses accounting for only a small portion of the curable.

Benefits of UV Curing

· It Offers Fast Production Capacity and Speed - Manufacturers want fast curing solutions with high output to keep business booming. UV Curing offers these and more. They allow for high-speed production, reduced space, and less labor. This curing technology ensures all your high-capacity machines to the job.

· Simplicity - The best part about UV Curing is its ease of use. This method does not need racks or ovens; UV curing requires cheaper equipment and operational costs than heat curing. UV curing ingredients are also a single component; therefore, you won't have to go through the mixing hassle. This avoids the possibility of waste and pot life issues.

· UV Curing Improves Physical Properties - UV Curing guarantees glossy, durable surface finishes, so you won't have to worry about scratched or damaged products. Additionally, your customers can enjoy products that are chemical resistant, sturdy, and can function efficiently in harsh conditions.

· Reduced Work-in-Process - Another benefit UV Curing offers is less production cycle time. This system is worth investing in as it will significantly reduce your work-in-process, saving you on manufacturing costs.

· Less Clean-Up and Set-Up Time - UV Curing chemicals do not dry when exposed to  UV energy. Your coating will go overnight on the machine without drying out. This is helpful for those using the curing for graphic printing business and those who use their UV curing system in machines that do coding and markings or plastic decoration.

· Environmentally friendly - With this curing method, you can avoid the hassle of investing in costly water equipment since the UV curing process does not require water, lowering your footprint. For instance, conventional water and steam processes create a necessity to safeguard staff and residents.

UV Curing Applications

Plastic Packaging

Various types of inks on plastics are cured using https://www.goodiuv.com/Product.htmlUV lamps. Most plastic-packaged products we use day-to-day are printed using this technology. Examples are cleaning products and candies. The UV curing method helps manufacturers boost their production effectiveness, which raises output and lowers expenses.


Some of the uses of UV Curing for printing are screen, offset, litho, flexo, and letterpress. UV printing's advantages include its instant curing, durability, optimum polish, adaptability (it may be used on absorbent and nonabsorbent surfaces similarly), and quick curing.

Decorating Metal

Manufacturers use UV curing to create a smooth, extremely flexible, and resistant surface on the can's rim during production and filling. Manufacturing efficiency means more money in your pocket. Aluminum and steel can benefit significantly from the additional abrasion and corrosion resistance of ultraviolet curing during the metal decoration process.

Take Away

UV curing technology is widely used; therefore, there are many possible combinations of UV light to meet all these application needs. At IUV, we can accommodate your needs, whether you're searching for a small curing system or a solution for bulk production. Our adjustable designs allow us to do just that.
