Careers

Valco offers envelope manufacturers a comprehensive gluing and quality assurance program.

•	Cold Glue and Hot-Melt Systems
•	Glue Line Inspection
•	Window/Insert Detection

Valco combines glue application and inspection in one control. The MCP25-MS microprocessor offers unequaled flexibility, performance and accuracy at any machine speed. The MCP25-MS utilizes an optical sensor to verify adhesive integrity for positioning, volume and length. If adhesive deposition doesn’t meet quality standards, faulty envelopes can be removed.

Valued customers can take advantage of special trade-in and exchange packages for an easy, cost-effective means to upgrade current gluing equipment.
