Automotive and mobility buyers increasingly specify vacuum formed prototype and short run parts instead of injection moulding or corrugated board. Here is where they are used and why they work.
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 vacuum formed prototype and short run 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 gauge 1.0 to 6.0 mm; lead times of 5 to 15 working days; single cavity prototype tools. Materials most often specified are High Density Polyethylene, Polyethylene Terephthalate Glycol, Polypropylene, Acrylonitrile Butadiene Styrene, 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 interior panels, under body shields, commercial vehicle trim.
The table below summarises the values that usually decide the material choice.
| Material | Density | Tensile strength | Service temperature |
|---|---|---|---|
| Polycarbonate | 1.20 g/cm³ | 55-70 MPa | -40°C to 120°C |
| Polypropylene | 0.90-0.91 g/cm³ | 25-40 MPa | -10°C to 100°C |
| Acrylonitrile Butadiene Styrene | 1.04-1.06 g/cm³ | 30-50 MPa | -20°C to 80°C |
Polyethylene Terephthalate Glycol is frequently the default selection here: PETG forms at lower temperatures and holds detail well, which is why it dominates medical trays.
In the automotive and mobility sector, these are the applications where this product has proven itself.
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.
The route below is the one most factories use for this type of part.
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.
A new tool typically takes 25 to 45 days depending on cavity count and complexity, followed by T1 samples within one week. Existing tools can usually start production within 10 to 15 days of order confirmation.
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. 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.
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.
Share your specification and quantity with us and we will recommend the most cost effective material, tooling route and packing method for your market.
