Unit price in thermoforming is dominated by material, cycle time and freight. Here is the full cost structure and the levers that actually move the number.
Use it as a working checklist when you write your next enquiry.
This category covers a family of products rather than a single item. In practice a buyer defines thermoformed refrigerator liners and door panels by three things: the base resin, the format or dimension, and the performance or certification level it has to meet. Typical options in this category include single piece liners over 1800 mm; textured and smooth finishes; deep draw geometries. Materials most often specified are Polypropylene, Acrylonitrile Butadiene Styrene, Polystyrene, High Density Polyethylene, and the choice between them changes stiffness, temperature resistance, chemical behaviour and price.
In the home appliance sector the decision is usually driven by deep draw capability and chemical resistance to insulation foam, with surface quality as a secondary requirement. Typical end uses include machine covers, freezer interiors, door panels.
The table below summarises the values that usually decide the material choice.
| Material | Density | Tensile strength | Service temperature |
|---|---|---|---|
| Acrylonitrile Butadiene Styrene | 1.04-1.06 g/cm³ | 30-50 MPa | -20°C to 80°C |
| Polypropylene | 0.90-0.91 g/cm³ | 25-40 MPa | -10°C to 100°C |
| High Density Polyethylene | 0.94-0.97 g/cm³ | 20-32 MPa | -50°C to 80°C |
High Density Polyethylene is frequently the default selection here: HDPE combines toughness with chemical inertness, which is why it dominates pipe and tank markets.
These are the levers buyers can actually influence when negotiating a thermoformed part.
Ask your supplier to quote two gauges and two cavity layouts; the difference shows which lever is worth optimising for your volume.
Beyond the base resin, most suppliers offer UV stabilised, food contact, flame retardant, anti-static and recycled content versions of the same product. Ask which additive package is included, because it is often the difference between a part that lasts three years and one that lasts ten.
Each step below has its own control points, and skipping one of them is where most defects start.
Secondary operations such as printing, welding, machining and assembly are often cheaper to do in the same factory, and they reduce the risk of mismatch between components.
Use this checklist when comparing two or three supplier quotations.
Send this list to your supplier with the drawing and you will receive comparable quotations from every factory you contact.
Yes. {mat1} is one of our regular materials for this item, and we can supply virgin, modified and certified grades with full traceability. Material certificates and test reports are issued per batch.
For standard sizes and colours the minimum is usually one pallet or one production run; for custom tooling the economic minimum depends on the tooling cost amortised over the expected volume. Send us your annual volume and we will calculate the break even point.
Standard production tolerance follows the relevant ISO or DIN tolerance class for the process; tighter tolerances are possible after machining or grinding, but they add cost. Define the tolerance only on the functional dimensions.
Standard packing is export cartons on fumigation-free pallets, with custom labelling, barcode and retail packing available. We also handle consolidated containers and door to door delivery.
Yes. Standard samples are normally free of charge and shipped within three working days; custom samples are charged at cost and credited against the first production order.
If you are planning a new home appliance project, send us your drawing, annual volume and target properties, and we will come back with a material proposal, a tooling plan and a budget quotation.
