Window manufacturing is all about precision, speed, and efficiency. When it comes to applying coatings or adhesives, even the smallest inconsistency can lead to costly rework or wasted materials. That’s why so many forward-thinking manufacturers are turning to Graco’s ProMix PD2K Proportioner. At HMFT, we’ve seen firsthand how this innovative system is transforming window production lines across Canada. Let’s dive into what makes the ProMix PD2K such a game-changer for our industry.

Precision Mixing for Consistent Quality

The ProMix PD2K uses 100% positive displacement technology, which means it delivers accurate mix ratios within 1% every single time. This level of precision is crucial for two-component materials, especially those with short pot life, ensuring that every window frame receives a flawless, durable finish. By mixing materials right near the spray gun, the system minimizes the amount of mixed product in the lines, so you get fresh, perfectly mixed material for every application.

Faster Colour Changes, Less Waste

If your production line handles multiple colours or frequent colour changes, you know how much time and material can be lost during flushing. The ProMix PD2K’s design moves the mixing point closer to the gun, drastically reducing the flush zone. This results in:

• Up to 80% less solvent and material waste compared to traditional proportioners
• Faster, push-button colour changes—often in under 30 seconds
• Significantly lower disposal costs and environmental impact

For window manufacturers juggling custom orders and a wide colour palette, these savings add up fast.

Unmatched Flexibility for Modern Production

Every window shop is unique, and the ProMix PD2K is built to adapt. It can handle up to 30 resin colours and 4 catalysts, making it perfect for both small-batch runs and high-volume production. Whether you’re spraying solvent-borne, waterborne, or acid-catalyzed coatings, this system can be tailored to your exact needs. And with its robust stainless steel and tungsten carbide construction, you can count on it to stand up to the demands of daily use.

Easy Integration and Smart Controls

The ProMix PD2K isn’t just powerful—it’s smart. It integrates seamlessly with plant automation and PLC systems via Ethernet, DeviceNet, Profibus, and more. The intuitive interface lets you pre-program mixing recipes, monitor ratios, and track maintenance schedules. Real-time data and alarms help you catch issues before they become problems, keeping your line running smoothly with minimal downtime.

Lower Maintenance, Higher Uptime

Traditional gear pumps and proportioners can be finicky and time-consuming to maintain. The ProMix PD2K’s positive displacement pumps are designed for quick, easy servicing—most maintenance tasks can be completed in under 20 minutes. With fewer moving parts and no need for constant fine-tuning, your team can spend less time fixing equipment and more time focused on production.
