Graco PC-8 InvisiPac Pattern Controller – Time & Distance Control without Encoder

Integrated Adhesive Pattern Control for Graco InvisiPac Hot Melt Systems

The Graco InvisiPac PC-8 Pattern Controller provides precise adhesive pattern control for InvisiPac hot melt systems as well as other compatible equipment where reliable standalone pattern control is required. It delivers consistent application through intuitive programming and dependable system integration. Using Graco’s Advanced Display Module (ADM), operators can quickly configure and adjust adhesive patterns to match application requirements while minimizing setup time.

The PC-8 operates in time-based or distance-based modes without the use of an encoder, making it well suited for applications where repeatable pattern control is required without line speed compensation. Supporting up to eight guns and four independent trigger inputs, the PC-8 offers flexible control for a wide range of packaging and industrial adhesive applications.

For applications requiring encoder-based distance control and line speed compensation, see the InvisiPac PC-8e Pattern Controller.
