SPA2 NANO UV

SPA2 Nano UV is a 355 nm UV laser coding system for manufacturers that need clear, high-contrast variable data on sensitive packaging and technical components.

The air-cooled 5 W DPSS UV laser can be evaluated for selected plastics, films, coated surfaces, glass and technical materials where fine detail, code readability and reduced thermal impact are essential.

High-contrast coding for sensitive packaging and components

UV laser coding creates a controlled reaction on the surface or a suitable coating layer. This makes it a relevant option for applications where conventional laser wavelengths may cause excessive heat effects, insufficient contrast or unwanted surface alteration.

SPA2 Nano UV can be assessed for coding:

• Best-before, expiry and production dates.
• Batch, lot and shift codes.
• Serial numbers and product references.
• Barcodes, QR codes and DataMatrix codes.
• Logos, small text and regulatory information.

The final result depends on the material, color, coating, print layer, code size, contrast requirement and line speed.

Why choose a UV laser coding system?

Reduced thermal impact on suitable materials

The 355 nm UV wavelength and short pulse duration allow precise marking with controlled heat input. This is particularly useful for selected sensitive plastics, films, coated materials and packaging formats.

Fine, high-contrast codes

SPA2 Nano UV supports small characters, variable data and machine-readable codes where readability and visual quality are important. Code quality should always be validated on the real product.

No ink or ribbons at the coding point

The laser creates the code directly on the selected surface or coding area. This removes the need to transfer ink or thermal-transfer ribbons during the coding process and can simplify consumable handling on the line.

Designed for production-line integration

Compact format and flexible marking position

SPA2 Nano UV has a compact, air-cooled design and an internal XQS marking head. Its beam exit can be configured from 0° to 90°, helping adapt the system to available space and marking position on the line.

H3: Variable data and industrial connectivity

TCP/IP connectivity is included as standard. Profinet, OPC-UA and EtherNet/IP can be specified when required by the production-line automation architecture.

This allows the laser to receive and manage variable information, including dates, batches, references and serialised codes.

Straightforward operation and maintenance

The system can be configured with a 10.1-inch touchscreen controller and MarcaTouch OS. Operators can create and manage messages, including templates for dates, barcodes, QR codes and DataMatrix codes.

Materials and applications

SPA2 Nano UV can be evaluated for a range of packaging and industrial applications, including:

• PET, PP, HDPE, ABS, PBT and selected engineering plastics.
• Printed, coated and selected flexible packaging materials.
• Bottles, tubs, lids, dispensers, wraps and labels.
• Glass and coated surfaces.
• Electronics, personal care, pharmaceutical, food and beverage packaging.
• Automotive and technical components requiring fine codes or reduced thermal impact.

Material suitability must be confirmed through a marking test. The polymer, pigment, additive package, color, coating and finish can all affect the result.

Validate your UV laser coding application

A material name alone is not enough to select a laser. Macsa id tests the actual pack or component to assess contrast, code readability, surface impact, marking position and production-line conditions.

We then recommend the laser configuration, optics and integration approach that best fits the application.
