Acrylonitrile Butadiene Styrene (ABS) and Polyethylene Terephthalate Glycol (PETG) are the two most quoted sheet materials for pressure formed precision parts in automotive and mobility 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 pressure formed precision parts 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 undercut capable tooling; gauge 1.0 to 6.0 mm; sharp detail and crisp radii. Materials most often specified are Polypropylene, Acrylonitrile Butadiene Styrene, Polyethylene Terephthalate Glycol, Polycarbonate, and the choice between them changes stiffness, temperature resistance, chemical behaviour and price.
In the automotive and mobility sector the decision is usually driven by dimensional stability and heat resistance, with impact strength as a secondary requirement. Typical end uses include commercial vehicle trim, under body shields, line side trays.
Typical values for a general purpose grade are listed below; filled, stabilised and speciality compounds will differ.
| Material | Density | Tensile strength | Service temperature |
|---|---|---|---|
| Polypropylene | 0.90-0.91 g/cm³ | 25-40 MPa | -10°C to 100°C |
| Polyethylene Terephthalate Glycol | 1.27 g/cm³ | 45-55 MPa | -40°C to 70°C |
| PC/ABS Alloy | 1.13-1.15 g/cm³ | 45-60 MPa | -30°C to 110°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 Polyethylene Terephthalate Glycol brings excellent clarity with no stress whitening. For automotive and mobility service the difference shows up in chemical resistance and in the long term behaviour under load.
In short: choose the first option when stiffness, heat and dimensional stability dominate; choose the second when impact, cost and processing speed matter more.
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.
Work through these points in order and most specification mistakes disappear.
Send this list to your supplier with the drawing and you will receive comparable quotations from every factory you contact.
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.
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.
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.
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.
Colour is controlled with a masterbatch reference approved by the customer, and every production lot is checked against the approved sample under standard lighting before shipment.
Share your specification and quantity with us and we will recommend the most cost effective material, tooling route and packing method for your market.
