What is the minimum order quantity for custom sandwich panel production?

compoform · 08 Sep 2026

For custom sandwich panel production, there is no universal minimum order quantity that applies to every project. MOQ depends on panel dimensions, core and skin configuration, and how much of a production run your specification requires to be economically viable. For mid-volume manufacturers, the practical threshold is typically measured in square meters of material rather than a fixed number of panels.

The more relevant question is whether your volume is large enough to justify a dedicated production run for your specification. Panels produced on a continuous double belt press, the standard for thermoplastic sandwich panels, require setup time and material changeovers that need to be spread across a meaningful run length to keep unit costs reasonable. The sections below answer the most common questions buyers ask before placing their first custom order.

Does panel size affect the minimum order quantity?

Yes, panel size directly affects the minimum order quantity for custom sandwich panels. Larger panels cover more square meters per unit, so fewer panels are needed to fill a production run of the same total area. A buyer ordering panels at maximum format — up to 13,500mm x 2,950mm — will reach the production threshold with far fewer individual pieces than a buyer ordering smaller cut panels.

This matters practically because production lines for thermoplastic sandwich panels run continuously. The line does not stop between panels — it produces a continuous sheet that is then cut to length. Setup costs, material loading, and line calibration are fixed regardless of how many meters you order. Spreading those fixed costs across a larger total area reduces the cost per square meter and lowers the effective MOQ in unit terms.

Panel thickness also plays a role. Thicker panels — for example, a 30mm floor panel with a PP-honeycomb core — move through the line more slowly than thinner wall panels. A run of thick, heavy-duty panels may require a higher minimum square meterage to be commercially viable compared to a run of lighter, thinner panels.

How do manufacturers calculate MOQ for composite panels?

Manufacturers calculate MOQ for composite sandwich panels based on the total square meters needed to cover fixed production costs at an acceptable unit price. The calculation accounts for line setup time, raw material minimum batch sizes, and the cost of any tooling or configuration changes specific to your specification. There is no single formula — it is a function of your panel’s complexity and the manufacturer’s production setup.

The key cost drivers that shape MOQ calculations include:

Core material batch size: PP-foam cores are available in multiple density grades (from 40 to 140 kg/m³), and each density grade requires a separate material batch. Switching grades mid-run adds cost and waste.
Skin configuration: The number of plies, fibre orientation, and surface finish (such as a white PET film or black anti-skid surface) each affect how the line is configured. More complex skin architectures increase setup time.
Line speed and throughput: A production line capable of 1.5 million square meters per year has significant capacity, but each configuration change reduces effective output. MOQ is partly a function of how long your run needs to be to justify that change.
Pallet and logistics configuration: Custom pallet layouts for oversized panels add handling steps. These are typically absorbed across the full order volume.

In practice, manufacturers will give you a square-meter threshold rather than a panel count. If your project falls below that threshold, the options are either to consolidate orders, accept a higher unit price for a short run, or align your order timing with another customer’s run using compatible materials.

What’s the difference between MOQ for standard and fully custom panels?

Standard panels carry a lower MOQ because the production configuration already exists. The line is set up, the materials are stocked, and the process is validated. Fully custom panels — with a unique thickness, core density, skin layup, or non-standard dimension — require a dedicated setup, which pushes the MOQ higher to recover those one-time costs.

The distinction is meaningful for buyers comparing off-the-shelf composite panels against made-to-order solutions. Standard configurations such as a 17mm wall panel with a cross-ply skin on a 60 kg/m³ PP-foam core, or an 11mm scaffolding panel with a 90-0-90 layup, can be produced with shorter lead times and lower entry volumes because no new configuration work is needed.

Fully custom panels introduce variables at every layer of the build:

A non-standard core density requires a specific foam or honeycomb batch
A unique skin ply count or fibre orientation requires line reconfiguration and test panels before full production begins
A non-standard surface finish or panel width outside the standard range adds further complexity

That said, the MOQ premium for custom panels is not unlimited. Once a configuration is validated and enters serial production, subsequent orders of the same specification carry the same economics as a standard panel. The first run absorbs the setup cost; repeat orders do not.

Can smaller manufacturers still access custom panel production?

Smaller manufacturers can access custom sandwich panel production, but the economics work best when order volumes align with the production line’s minimum viable run length. The practical route for lower-volume buyers is to consolidate requirements — ordering a larger batch less frequently rather than small batches on short cycles — or to work with a manufacturer who can schedule your run alongside compatible orders.

For truck body builders, trailer manufacturers, and specialist vehicle assemblers operating at mid-volume scale, custom panel production is often more accessible than it appears. The reason is that custom dimensions do not always mean a unique material configuration. A buyer who needs panels cut to a specific length and width, but using a standard core and skin combination, may face a much lower MOQ than a buyer specifying an entirely new material stack.

It is also worth noting that end-user demand increasingly drives the shift to composite panels regardless of manufacturer size. Fleet operators and logistics companies specifying composite floors or walls in their procurement requirements effectively pull their suppliers toward composite sourcing. This pull-through demand means smaller OEMs are often entering composite panel procurement applications not by choice, but because their customers require it — which strengthens the case for finding a production partner who can work at their volume.

What happens if your order falls below the minimum quantity?

If your order falls below the minimum quantity for a custom sandwich panel run, you typically face one of three outcomes: a higher unit price to compensate for the short run, a request to defer your order until it can be combined with a compatible production run, or a recommendation to use the closest available standard configuration instead.

A higher unit price for a short run is not always a bad outcome. For buyers who need a small quantity of a specific panel to validate a new vehicle design or test a new application, paying a premium for a short run is often preferable to committing to a full production volume before the design is confirmed. Many manufacturers will accommodate this as a development or prototype run, with the understanding that serial production follows at standard MOQ.

Deferring to a combined run is common in practice. If your specification uses a core and skin combination that another customer is already running, a manufacturer can schedule your panels within that run and pass on the efficiency. This requires flexibility on lead time but can significantly reduce cost.

The worst outcome — and one worth avoiding — is placing an order that technically meets the MOQ but stretches your inventory beyond what your production schedule can absorb. Overstocking composite panels to hit a volume threshold ties up working capital and creates storage challenges for large-format panels. A better approach is to align your order volume with your actual consumption rate and negotiate a blanket order or call-off arrangement with your supplier.

How Compoform Approaches Minimum Order Quantities

We do not apply a single fixed MOQ across all configurations. Because we produce panels on a 72-meter continuous double belt press capable of panels up to 13,500mm x 2,950mm x 150mm, the viable minimum for your order depends on your specific panel build — core material, skin architecture, thickness, and dimensions.

Here is how we work with buyers to make custom production viable at their volume:

Configuration review before quoting: We review your panel specification and identify whether your requirements can be met within an existing production configuration or require a dedicated setup. This determines whether standard or custom MOQ thresholds apply.
Call-off and blanket order arrangements: For buyers with consistent but moderate demand, we can structure blanket orders that commit to a total annual volume while releasing panels in scheduled batches. This keeps your inventory lean without sacrificing production efficiency.
Development runs for new applications: If you are validating a new truck body design, trailer floor, or scaffolding board specification, we can accommodate a short development run at a defined cost before committing to serial production volumes.
Panel optimisation for your assembly process: We review your design before production begins, not just to confirm the specification, but to flag whether a different core density, skin layup, or panel dimension would perform equally well at a lower cost or with better fit to your assembly line.

For truck body builders and trailer manufacturers, a 30mm PP-honeycomb floor panel from our range is self-supporting — no aluminium subframe is required. That removes a production step and reduces your total build cost, which changes the economics of the panel price relative to your full assembly cost. Over a 15-year vehicle life, eliminating two or three plywood replacement cycles adds further value that a unit price comparison does not capture.

If you are working through a new panel specification or trying to understand whether your volumes are a fit for custom production, speak with our engineering team directly. We will review your application, confirm the right configuration, and give you a clear picture of what production looks like at your scale — before you commit to anything.
