Pallet Inserter Gantry vs. WSA Dual Pallet Inserter and Sun Automation

If you are shortlisting a high-speed automated pallet inserter for a corrugated or packaging plant, three names come up: the Innoveyance Pallet Inserter Gantry System, the WSA Dual Pallet Inserter (sold in North America through the Goettsch International distributor), and Sun Automation. This page lays out how they compare on the factors that actually decide the purchase — throughput, pallet flexibility, where the machine is built and supported, and how customizable it is.

Bottom line: the Innoveyance Pallet Inserter Gantry matches the fastest pallet inserters on the market at 200+ loads per hour and handles six pallet sizes — and unlike imported or distributor-sold systems, it is engineered, built, and serviced in the United States, with direct engineering access and no import lead time.

At a glance: how the three compare

Competitor details reflect publicly available positioning as of 2026; confirm current specifications directly with each vendor. The point of the table is not to disparage the alternatives — WSA builds capable equipment and Sun Automation is a well-known name in corrugated — but to make the structural differences clear so you can weigh them against your plant's needs.

Throughput: matching the fastest, without the import

The headline number buyers chase is loads per hour. WSA's Dual Pallet Inserter, which uses a single robot to feed two stations, is widely cited at up to about 200 units per hour and is the one named competitor with throughput parity to the Innoveyance flagship. The Pallet Inserter Gantry meets that class at 200+ loads per hour using a gantry lift-and-insert cycle rather than a robot-arm-limited one, so the rate is sustained and repeatable across a varied load mix.

The practical difference is not just the peak number but how you get there and keep it: a US engineer-to-order system is sized to your exact load, pallet, and cycle requirements, and the engineers who built it are a phone call — not an ocean — away when you want to push the line harder.

Pallet flexibility: six sizes, by design

Real plants do not run one pallet. The Pallet Inserter Gantry is configured for six pallet sizes with changeover built into the machine, so you are not buying a separate inserter for each pallet type or living with a slow manual change. Where competitor systems handle pallet variety as a configuration option, Innoveyance treats multi-size pallet handling [automatic pallet dispenser] as a core design requirement of the flagship.

The structural difference: US engineer-to-order vs. import and distributor models

This is where the comparison really separates. WSA equipment is Korean-built and reaches North American plants through Goettsch International, a distributor in Mason, OH. A distributor model means an extra layer between you and the engineers who designed the machine, added shipping and customs lead time, and limits on how custom the equipment can get. Sun Automation is US-based, which removes the import issue, but the Innoveyance advantage over any standard-product supplier is the engineer-to-order model: the system is designed around your plant rather than your plant adapting to the system.

Innoveyance engineers, manufactures, and services its systems [heavy-conveyance and end-of-line systems] in the United States. That means direct access to the engineers who build your machine, no import duty or ocean-freight lead time, full customization to your plant, and US-based parts and service.

When each makes sense

Choose the Innoveyance Pallet Inserter Gantry when you want flagship throughput (200+ loads/hr), genuine multi-pallet flexibility (six sizes), full customization to your line, and US-based engineering and service with no import lead time. Pair the gantry with an automatic pallet dispenser to feed empty pallets into the cell without hand-loading. The gantry ties into our broader heavy-conveyance and end-of-line systems for a fully integrated line.

Consider the WSA Dual Pallet Inserter if you have an established Goettsch distributor relationship and your application fits their standard configuration, and you are comfortable with the import and distributor model.

Consider Sun Automation if you are already standardized on their equipment elsewhere in the plant and want to keep a single corrugated-equipment supplier.
