Behind every consistent thermoformed part there is a controlled process. This article walks through sheet extrusion, heating, forming, trimming and the inspection steps that matter.
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 automotive interior 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 textured and laminated surfaces; large panels over 1500 mm; UV stabilised grades. Materials most often specified are PC/ABS Alloy, Polypropylene, High Density Polyethylene, Acrylonitrile Butadiene Styrene, 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 kiosk shells, protective guards, machine housings.
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 |
| High Density Polyethylene | 0.94-0.97 g/cm³ | 20-32 MPa | -50°C to 80°C |
| PC/ABS Alloy | 1.13-1.15 g/cm³ | 45-60 MPa | -30°C to 110°C |
PC/ABS Alloy is frequently the default selection here: PC/ABS is the standard engineering alloy for electronics housings that must survive a drop test.
Processing method drives both cost and performance, so it should be fixed early in the design.
Critical control points are melt temperature, cooling time and the inspection of the first pieces of every shift. A stable process is documented with a parameter sheet that travels with the tool.
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.
These are the criteria that actually predict whether the part will perform in service.

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.
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.
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.
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.
Our team supplies thermoformed automotive interior panels to industrial equipment customers worldwide, with samples, material certificates and full inspection reports available before mass production.
