In sports and leisure projects, automotive plastic components is only acceptable when the paperwork is right. This article maps the standards, test methods and documents you should ask for.
The notes below come from day to day production and export work with overseas buyers.
This category covers a family of products rather than a single item. In practice a buyer defines automotive plastic components 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 structural glass filled grades; bumper to clip scale; class A painted surfaces. Materials most often specified are Thermoplastic Elastomer, Polyamide, Acrylonitrile Butadiene Styrene, Polypropylene, and the choice between them changes stiffness, temperature resistance, chemical behaviour and price.
In the sports and leisure sector the decision is usually driven by impact absorption and light weight, with comfort as a secondary requirement. Typical end uses include playground components, helmet shells, kayak hulls.
The table below summarises the values that usually decide the material choice.
| Material | Density | Tensile strength | Service temperature |
|---|---|---|---|
| Polyamide | 1.13-1.15 g/cm³ | 60-85 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 |
Polypropylene is frequently the default selection here: PP is the lightest mainstream packaging resin and keeps its shape under repeated flexing.
The following standards are the ones most often referenced in this product category.
Ask the supplier to state the standard number, the test method and the result on the certificate. A test report without a standard reference is difficult to defend during an audit.
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.
These are the criteria that actually predict whether the part will perform in service.
Send this list to your supplier with the drawing and you will receive comparable quotations from every factory you contact.
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.
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.
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.
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.
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.
If you are planning a new sports and leisure 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.
