Smart automation for leak-free, coated, and digitally printed pails

Engineering automation that protects and decorates every pail

The paints, inks, and technical coatings industry faces several key challenges, including the high cost of pail decoration, compliance with evolving labeling regulations, maintaining consistent pail quality, and finding viable alternatives to expensive metal pails, which are prone to corrosion and carry high material costs.

Delta Engineering develops and builds advanced solutions that enable packaging and paint manufacturers to address these challenges head-on. Our systems ensure container integrity, improve solvent barrier performance, and enable flexible, on-demand artwork customization directly on the production line.

Leak testing

Even the smallest leak can cause product loss or contamination. Our in-line high-speed, non-destructive leak testing machines detect micro-leaks in every pail, ensuring top quality, reducing waste, and protecting both production flow and brand reputation.

Plasma coating

Our plasma coating technology adds a thin, uniform barrier to HDPE pails, creating durable, solvent-resistant alternatives to metal containers. It ensures consistent pail quality and enables recyclable, lightweight packaging with a lower cost and carbon footprint.

Digital printing

Our digital printing systems apply high-quality, full-color graphics directly to plastic pails at the last minute. No labels or tooling needed. With best-in-class color accuracy, recyclable inks, and fast changeovers, our system delivers flexible, cost-effective decoration that enhances brand visibility.

Proven technology, trusted by the industry

End-to-end solutions, developed with leading partners

We work with industry leaders such as Isytech and Shift ID to offer a combination of automation, coating, and printing expertise. Our systems are already used by leading multinational pail and paint manufacturers worldwide to reduce decoration costs, lower working capital, accelerate time-to-market, and improve sustainability in packaging production.

Smarter, more sustainable packaging

Achieve high solvent resistance with fully recyclable HDPE pails

Our plasma coating technology enables a reliable transition from metal to plastic packaging, combining solvent resistance, durability, and recyclability. It eliminates denting and corrosion while reducing transport weight, helping manufacturers lower costs and meet sustainability targets.

Smart decoration with virtually no waste

Digitally print any design, anytime

Digital printing gives packaging and paint manufacturers unmatched flexibility. Print-on-demand eliminates label stock, reduces setup time, and avoids waste. Designs can be personalized or regionalized instantly while maintaining consistent quality and color accuracy, all with recyclable inks.

Reliable performance and expert support

Continuous operation, supported globally

All Delta Engineering machines are designed for industrial-scale production and 24/7 operation. Backed by multilingual service teams and fast spare-part supply, we keep our customers’ coating and printing lines running at top performance, wherever they produce.

Every detail in paint packaging counts

In the paints, inks, and coatings industry, quality depends on more than what goes into the container. It’s also about how the container performs. Delta Engineering’s automation systems for leak testing, plasma coating, and digital printing help packaging manufacturers deliver solvent-resistant, visually striking pails. Each system is designed, built, and supported in-house, ensuring consistent performance, seamless integration, and long-term reliability for paints, inks, and coating packaging lines.

FAQ

The top 5 questions we get
from pail manufacturers

How do we effectively leak test pails for solvent-based products at production speed?

Use on-the-fly pressure-decay or rotary leak testing sized to your throughput, combined with calibration and positive ejection logic. Rotary systems reach up to 40,000 BPH with minimal false rejects, while calibration tools keep accuracy stable on warm, in-line products. Positive ejection treats any uncertain unit as defective, which drives customer complaints toward zero.

Can plasma-coated HDPE really replace metal pails for paints and coatings?

Which solvents are compatible with plasma-coated pails and how do we qualify them?

How does digital printing compare to labels or IML for pails?

What are the operational gains from integrating leak testing, plasma coating, and digital printing on one line?
