Acrylonitrile Butadiene Styrene (ABS) and High Density Polyethylene (HDPE) are the two most quoted sheet materials for returnable and reusable thermoformed trays in industrial equipment projects. Both run well on standard thermoforming equipment, but they differ in clarity, toughness and sealing.
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 returnable and reusable thermoformed trays 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 stack and nest configurations; standard footprints 400 x 600 mm; gauge 1.5 to 6.0 mm. Materials most often specified are Polyethylene Terephthalate, Polycarbonate, Polypropylene, High Density Polyethylene, and the choice between them changes stiffness, temperature resistance, chemical behaviour and price.
In the industrial equipment sector the decision is usually driven by thick gauge capability and flare and fire rating, with paintability as a secondary requirement. Typical end uses include equipment covers, twin sheet panels, machine housings.
These figures are typical for commercial grades and should be confirmed against the supplier's certificate for your specific lot.
| Material | Density | Tensile strength | Service temperature |
|---|---|---|---|
| High Density Polyethylene | 0.94-0.97 g/cm³ | 20-32 MPa | -50°C to 80°C |
| Polypropylene | 0.90-0.91 g/cm³ | 25-40 MPa | -10°C to 100°C |
| Polycarbonate | 1.20 g/cm³ | 55-70 MPa | -40°C to 120°C |
Acrylonitrile Butadiene Styrene is frequently the default selection here: ABS is the default choice when a part needs a glossy, paintable, impact-resistant surface.
Acrylonitrile Butadiene Styrene grades offer high impact toughness, while High Density Polyethylene brings high impact strength even at low temperature. For industrial equipment service the difference shows up in chemical resistance and in the long term behaviour under load.
The practical decision usually comes down to the service environment: temperature, chemical exposure and expected lifetime.
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. 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.
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 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.
We can provide ISO 9001 quality system documentation, material certificates, RoHS and REACH statements, and where applicable food contact, flame retardancy or drinking water approvals. Tell us your target market and we will match the document set.
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.
If you are planning a new industrial equipment 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.
