Macsa unveils ‘game-changing’ laser coders for packaging sector

MACSA ID UK has launched its SPA 2 series of modular laser coders for the packaging industry.

The firm said the newly ‘simplified’ platform delivers ‘maximum marking resolution and definition at higher speeds more consistently over time’.

Featuring a modular design, Macsa’s SPA 2 lasers can be integrated with any production line or application, and adapted to meet the changing needs of each user.

Providing marking on a range of packaging materials, including wood, thermal labels, board, metallised board, glass, ceramics, metals, rubber and plastics, the SPA 2 platform is available with CO2, DPSS and fibre technologies.

There are two basic printheads for different speed and quality requirements. The XQS printhead is suitable for most applications, while the HPD printhead is recommended for high resolution images, difficult substrates, product modification, and marking areas above 250mm2. A UHS printhead is available for very high speed lines and longer, more complex messages.

Due to the EEP (easy exchange printhead) feature, operators can switch printer heads on site using just two connectors.

The enclosure has been redesigned with a flat front surface allowing ‘simple’ integration of vision systems and other devices, Macsa added. With models that meet IP54 and IP65 standards, the SPA 2 lasers are designed to operate in dusty or damp environments and in extreme temperatures.

The RAF (reverse airflow cooling) system means filters are changed less frequently and not needed at all in some circumstances. A sealed air system transfers heat from the laser to the cooling air itself, eliminating the risk of dust being deposited directly into the system component.

The SPA 2’s surface recognition feature, which is included within its 3D printing kit, allows printing on multi-level surfaces. An external Z-axis controller enables operators to adapt the vertical coding axis to vary the height between print cycles and adapt it to different products.
