Choose a tool

Pick the product that matches the physical planning problem. Container loading and rotomolding mold layout need different models.

T1

Single SKU Loading

One carton size loaded into a container, a pallet area, leftover container space, or a larger box.

T3

Mixed Carton Loading

Multiple carton types in one container, with all six box orientations and an interactive quantity panel.

U3

Upright Palletized Loading

Mixed palletized cargo that must remain upright; supports both standard and non-standard pallet sizes.

RotoSpider

Rotomolding Mold Layout

Plan mold combinations on rotational molding machine spiders with straight-arm and offset-arm geometry.

How to choose

Use T1 when

All cartons share the same length, width, and height, and you need either the maximum count that fits or the smallest space for a fixed count.

Use T3 when

Several carton sizes are free to rotate and load directly into the container, with no upright-only rule.

Use U3 when

Cargo is palletized or must stay upright, and you need both automated planning and manual adjustment before shipping.

Use RotoSpider when

You are planning mold layouts for rotational molding machine spiders rather than loading cartons or pallets into a container.
