The New, Improved XD-360 — Bowl-Fed, Print, Cure, Inspect, Discharge
Cylindrical molded parts punish legacy decoration — and the part-feed and post-print inspection steps were still manual.
Application profile: a high-volume manufacturer of injection-molded plastic cylindrical parts. The geometry archetype is a small molded plastic body — roughly the height and diameter of a sprinkler head or a hardware closure — decorated 360° around the diameter with multi-color, in-register artwork. The same archetype shows up across irrigation hardware, dispensing closures, fluid-handling fittings, valve covers, and consumer-products sub-assemblies.
Cylindrical molded parts in the sprinkler-and-fitting size class punish legacy decoration. The decoration has to wrap a curved diameter, hit a registration feature, and survive field exposure to sun, water, and abrasion. Pad printing can only cover one face per stroke, so a full wrap requires multiple pad stations stacked end-to-end, each with its own cliché and ink cup. Screen printing on a round part requires a curved-surface fixture per SKU and runs slow. All of the analog options choke on changeover when the catalog has dozens of variants of the same base geometry.
Layered on top: parts have to be presented to the decoration line one at a time, oriented to a known datum, and inspected after print — because every defective part that escapes the cell is a field return waiting to happen. The previous-generation XD-360 already solved the cylindrical-print problem; what was still manual on the floor was the part-presentation step and the post-print inspection step. Those two steps were the remaining bottleneck.
One automated cell: bowl-feed in, error-detection out — the operator-touch points are gone.
The new, improved XD-360 closes both gaps. EPS integrated a vibratory bowl feeder at the front of the cell to present parts automatically, oriented and singulated, at line speed. At the back of the cell, EPS added an in-line error-detection station — a vision and laser-registration sensor that inspects each finished part before it is released to the discharge.
The result is a single automated cylindrical-decoration cell: parts go in from the bowl, get pretreated and printed 360° around the diameter with single white plus CMYK, are LED-UV cured in-line, are inspected for print quality and registration, and are discharged to the take-away — all without an operator touching the part between feed and exit. Inline load and unload are also options for customers whose upstream and downstream operations are already on a continuous conveyor.
EPS Perspective“Multi-pass cylindrical inkjet has been a workhorse for plastic cylindrical parts for years. What the new XD-360 changes is the cell around it: bowl-feed in, error-detection out, and inline load/unload as an option. The operator-touch points are gone. That is what ‘new and improved’ actually means on the production floor — fewer hands, fewer escapes, lower unit cost.” — EPS Applications Engineering
The Parts — Cylindrical Molded Hardware
The geometry archetype is a small molded plastic body — roughly the height and diameter of a sprinkler head or a hardware closure — decorated 360° around the diameter with multi-color, in-register artwork. The same archetype recurs across irrigation hardware, dispensing closures, fluid-handling fittings, valve covers, and consumer-products sub-assemblies.
Vibratory Bowl Feed
Parts arrive at the cell in bulk and are loaded into the integrated vibratory bowl feeder. The bowl orients each part to a known datum and singulates them onto a transport rail that delivers them, one at a time, to the XD-360's print station. This is the step that used to be manual; on the new XD-360 it is part of the cell.
In-Line Pretreatment
In-line surface activation (configured to substrate) raises the surface energy of the molded plastic immediately before the ink lands. Because the pretreatment is integrated into the cell rather than run as a separate operation, the activation is fresh — no degradation window, no offline WIP, no second handling.
Multi-Pass 360° Print + LED-UV Cure
Each part indexes onto a rotation fixture and rotates through 360° while the XD-360's print head array lays down single white plus CMYK in a coordinated multi-pass sequence. LED-UV pins each color before the next pass and fully cures the print before the part exits the print station. The full wrap is decorated in one cell.
In-Line Error Detection
Each finished part advances to an in-line inspection station. A vision sensor with laser registration verifies print quality, color count, and registration against the recipe. Parts that pass are released to the discharge; parts that fail are flagged and diverted before they reach packout. This is the second new feature on the improved XD-360, and it eliminates the offline manual-inspection step.
Discharge
Verified parts exit the cell on a powered take-away and are queued for downstream assembly or packout. Inline load and unload are also options when the customer's line is already conveyorized.
What the new, improved XD-360 cell delivers in production.
Feed, print, cure, inspect, discharge — one cell
One automated cell now performs part feeding, pretreatment, multi-pass 360° decoration, LED-UV cure, error-detection inspection, and discharge. No operator touches the part between feed and exit.
Two manual steps eliminated
The integrated vibratory bowl feeder and in-line error-detection inspection remove the two remaining manual steps in the prior workflow — part presentation and post-print inspection.
360° decoration in a single station
The full wrap is decorated in one station rather than face-by-face across multiple stacked pad stations, each with its own cliché and ink cup.
Per-SKU tooling cost goes to zero
No plates, no clichés, no per-part fixtures beyond the standard XD-360 part-handling kit. New variants are digital artwork files, not new tooling orders.
Fewer escapes to the field
In-line inspection flags and diverts defective parts before packout — every defective part caught in the cell is a field return that never happens.
Inline load/unload available
Bowl-fed is standard; inline load and unload are available for customers running continuous conveyor lines upstream and downstream of decoration.
