If you specify Polypropylene (PP) for pressure formed precision parts, a handful of properties decide whether the part survives forming and service. These are the values worth checking on every data sheet.
Everything here can be checked on a real sample before you commit to a production order.
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 sharp detail and crisp radii; textured in-tool surfaces; undercut capable tooling. Materials most often specified are Polypropylene, Polyethylene Terephthalate Glycol, PC/ABS Alloy, 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 under body shields, interior panels, line side trays.
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 |
|---|---|---|---|
| Polycarbonate | 1.20 g/cm³ | 55-70 MPa | -40°C to 120°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 |
Polypropylene is frequently the default selection here: PP is the lightest mainstream packaging resin and keeps its shape under repeated flexing.
The table below summarises the values that usually decide the material choice.
Density 0.90-0.91 g/cm³, tensile strength 25-40 MPa, continuous service temperature -10°C to 100°C and melt range 160-170°C are the four values to circle on the data sheet. Everything else is secondary for most automotive and mobility projects.
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.
Processing method drives both cost and performance, so it should be fixed early in the design.
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.

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.
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.
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.
Share your specification and quantity with us and we will recommend the most cost effective material, tooling route and packing method for your market.
