Why aluminium composite panel makers need ACP ERP software
Aluminium composite panel manufacturing combines metal coating, polymer extrusion and continuous lamination in one plant. Material enters as aluminium coils weighed in kilograms, paint in litres, and polyethylene or fire-retardant core compound in bags. It leaves as panels counted in sheets but sold in sq ft or sq m, in dozens of shades, several sheet sizes, two or three thicknesses and different core grades. ACP ERP software is built to hold all of these together.
Keeping that straight in registers is hard, and the errors are expensive. A coil issued without its number, a shade code typed wrongly on an invoice, or a mixed batch delivered to a facade project can all lead to complaints that are difficult to resolve. ACP ERP software ties each sheet back to the coil, the paint batch and the lamination run it came from. DotOne is the system we configure for ACP, aluminium sheet coating and related panel manufacturers.
Materials and how they are stocked
- Aluminium coils: received with coil number, alloy, temper, thickness in mm, width, weight and supplier test certificate, stocked coil by coil.
- Paints and coatings: primers, PE, HDP, PVDF or FEVE top coats and back coats, tracked by batch and shade code with shelf life.
- Thinners and pretreatment chemicals: tracked in litres or kilograms with consumption per run.
- Core materials: LDPE granules, recycled polymer and mineral-filled fire-retardant compound, stocked in kilograms by grade.
- Adhesive or bonding film: rolls by width and length, issued per lamination run.
- Protective film: printed or plain film by width, often branded, applied on the coated face.
- Packing material: pallets, corner guards, interleaving sheets and wrapping.
Because aluminium is bought by weight but used by area, the ERP converts coil weight into running metres and sq m using thickness, width and density. That conversion is central to yield and cost, and to sound inventory management in an ACP plant.
Coil coating, core extrusion and lamination
Coil coating
On the coating line, the coil is cleaned, pretreated, primed and top coated, then cured in the oven. The ERP records coil number, paint batches, shade, line speed, oven temperatures, dry film thickness in microns and gloss. Coated output is booked as a coated coil with its remaining length and area, and paint consumption per sq m is compared with standard.
Core extrusion
Polymer or FR compound is extruded into a continuous core of the required thickness. Material mix, extrusion parameters and core weight per sq m are recorded, along with start-up waste and purging.
Lamination
The core is bonded between the coated top skin and the back skin using adhesive film under heat and pressure. Each lamination run links the top coil, bottom coil, core batch and adhesive roll. Peel strength and bond tests are recorded per run.
Cutting, filming and stacking
The continuous panel is cut to length, protective film is applied, and sheets are stacked on pallets by shade, size and thickness. Edge trim and cut-off waste are booked with reasons.
Shade, size, thickness and core as one item matrix
An ACP catalogue includes solid colours, metallics, wooden and stone textures, brushed and mirror finishes, each with its own shade code. Each can be made in standard sizes such as 1220 by 2440 mm or 1220 by 3050 mm, or custom lengths for projects, in 3 mm, 4 mm or other thicknesses, with PE or FR core. We set these up as item attributes so that the catalogue is maintained once and every valid combination is available for planning and sales.
Stock reports then show what is available by shade and size at a glance, and production can be planned to group shades on the coating line and minimise colour changeovers. Custom project sizes are created against the sales order without cluttering the standard catalogue.
Quality, rejection and project traceability
ACP quality issues tend to show up after installation, on a building facade where replacing panels is costly. That makes traceability important. Every pallet in the ERP carries the lamination run, which links back to coated coil numbers, paint batches and core batch.
- Shade variation between batches, especially for metallic and PVDF shades.
- Coating defects such as orange peel, pinholes, craters and low DFT.
- Delamination or low peel strength from bonding issues.
- Surface dents, scratches, roller marks and protective film defects.
- Edge damage and length or squareness variation after cutting.
For large facade orders, the ERP can reserve sheets from the same coating batch so that the whole elevation is supplied from one batch. Test results are stored against the batch for the documentation customers often request. The batch traceability setup explains how this genealogy works.
Planning the coating line and handling scrap
Shade changes on a coil coating line cost time, solvent and paint, so planners try to run similar shades together and move from light to dark. The ERP groups pending orders and reorder requirements by shade and coating type, checks coil and paint availability, and proposes a coating sequence that the planner can adjust. Lamination is then planned by core type and thickness to limit changeovers on the extruder. The production planning module holds these sequences and shows their effect on promised dates.
Scrap in an ACP plant has real value. Coil ends, trimmed edges, rejected panels and purged core are booked into separate scrap items by type, so that aluminium scrap, mixed panel scrap and polymer regrind are weighed, stocked and sold or reused with proper records rather than leaving the gate unaccounted.
Costing ACP per sq ft and per sheet
The cost of an ACP sheet is dominated by aluminium, followed by coating and core. Small differences in skin thickness, paint consumption or core weight change the margin noticeably. DotOne builds cost from actual data: aluminium in kilograms converted to area, paint at actual consumption per sq m, core weight, adhesive film, protective film, line time, energy and packing, plus a share of trim and rejection.
Management sees cost per sq ft and per sheet by shade family, thickness and core type, and compares it with the realised price for distributors, fabricators and project customers. When aluminium prices move, estimated costs for open quotations update from current purchase rates. Our costing software page explains the costing methods we set up.
Sales channels, projects and dispatch
ACP is sold through distributors and dealers to fabricators and signage makers, and directly to facade contractors for building projects. Dealer business needs price lists by shade group, schemes and credit control. Project business needs quotations with specific shades, sizes and quantities, approval of samples, staggered delivery schedules and batch reservation.
The ERP handles both from the same sales order management module. Dispatch documents list pallets with sheets by shade, size and thickness, and generate the GST e-invoice and e-way bill. Transporter details and delivery confirmation are recorded so that project deliveries can be tracked against the schedule.
What is the best ERP for ACP manufacturers?
Judge any ACP ERP software on whether it handles coils and shades properly. During evaluation, ask the vendor to receive a coil with its number and weight, coat it in a shade, laminate it with a core batch, cut sheets of two sizes and trace a sheet back to the coil. Then check whether paint consumption per sq m, core weight and trim waste are captured, and whether stock is visible by shade and size on mobile for your sales team. If the demo cannot do this with your data, the plant will keep its parallel registers.
