What is Precision Spot Curing?

Precision spot curing is the controlled use of focused UV light to a particular spot, which can have a size as small as a few millimeters. This approach allows for:

• Localized adhesive cure, reducing the waste of materials.
• Sensitive parts require high-accuracy curing technology.
• Micro-spot UV curing to address the needs of small assemblies.

All these features make precision curing machines essential in those industries where the slightest error affects the quality of the products. LED spot curing technology allows manufacturers to obtain consistency in the UV curing cycles with consistent intensity and micro-spot curing reliability throughout the production cycle.

Technical Benefits of Precision Spot Curing

Current UV LED precise curing machines take advantage of new chip-on-board UV LEDs and narrow beam ultraviolet curing designs to provide focused energy to effectively cure. The technical benefits are:

• Spot curing LEDs with high output and the ability to produce intense UV energy at a low-heat operation.
• Photon emission control of fine irradiance spots.
• UV spot curing that entails thermal management to keep the system long-lasting and safe from materials.
• Control of UV wavelengths at nanometers, with adhesives, coatings, and resins customized.

All these technical advances have rendered precision spot curing an appropriate choice for applications spanning the mass production of industry, down to the micro-assembly of a part that must be produced with utmost accuracy.
