Designed for dispensing. An independent dispense‑clean‑out button on the front panel allows you to flush the nozzle of a single dispensing valve, preventing adhesive from curing or assisting with initial setup. No special programming is required. It supports nozzle misalignment calibration. The teach pendant’s program‑storage feature enables easy transfer of dispensing programs from one robot to another. An overspeed indicator light prevents the robot from running too fast during program execution. Up to 100 programs are supported, with 4,000 memory points per program.

Glue application without gas contact minimizes air entrainment within the product, preventing premature curing of the acrylic adhesive. The vacuum‑assisted backflow feature enables timely reversal to halt liquid flow and prevent dripping. Adjustable settings allow precise control of the vacuum‑hold delay time. A simple, user‑friendly mechanical design facilitates quick hose replacement. Glue dispensing operates in a continuous fire‑timing mode.

APP is atactic polypropylene, a byproduct generated during polypropylene production. Starting in the 1970s and 1980s, both domestically and internationally, researchers began exploring ways to comprehensively utilize this byproduct. Over time, significant breakthroughs were achieved in areas such as asphalt modification, adhesives, rubber–plastic modification, and coating formulations, establishing APP as a highly regarded specialty chemical. As production processes evolved, the amount of APP generated as a byproduct declined, prompting several companies in Europe and North America to adopt dedicated manufacturing technologies for its targeted production, now reaching scales of tens of thousands of tons per year. However, nomenclature varies across regions, with terms such as APP (atactic polypropylene), APAO (amorphous α‑olefin copolymer), and APOs (“amorphous polyolefins”) all referring to products of the same class.
