What is a Spot Curing System?
Introduction
In the modern era of high-technology production, accuracy and speed are all that matter. The Spot Curing System comes in at that point. It is not any other UV curing tool. It is a disruptor to such industries as electronics, optics, medical devices, and automotive. As compared to the conventional curing lamps that require time to warm up, a UV LED System has an instant-on capability, high intensity, and unparalleled accuracy. You have micro-assemblies, curing adhesives on delicate surfaces, bonding miniature components, or want control, uniformity, and efficiency. A system provides you with control, consistency, and efficiency.
What is a Spot Curing System?
A Spot Curing System is a small-scale, high-intensity UV curing system that is designed to cure small, specific areas. It does not produce a wide-ranging surface of UV light but generates a specific UV beam that is focused to cure adhesives, coatings, and inks in the precise area required.
The technology utilizes either UV LEDs or mercury arc lamps, although new systems are increasingly adopting solid-state UV LEDs as they have good life, require minimal maintenance, and consume less energy.
The UV LED Spot Curing System
The UV LED Spot Curing System (Model: NSC4) is designed to provide high speed of curing, low energy consumption, and extended service. It is intended to be used in the industrial adhesive and coating industry to ensure accurate management of UV and low heat production. It is available in a variety of wavelengths (365nm, 385nm, 395nm, 405nm), enabling smooth transition to several hundred materials and processes and guaranteeing uniform results in electronics, optics, and the assembly of medical devices.
