Choosing the right electronic plastic housings and enclosures for automotive applications is rarely about picking the cheapest quote. It is about matching resin properties, processing method and certification to the way the part will actually be used.
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 electronic plastic housings and enclosures 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 bosses and snap fits; wall thickness 1.2 to 3.0 mm; transparent windows and light pipes. Materials most often specified are Polystyrene, Glass Filled Nylon, Acrylonitrile Butadiene Styrene, PC/ABS Alloy, and the choice between them changes stiffness, temperature resistance, chemical behaviour and price.
In the automotive sector the decision is usually driven by weight reduction and impact resistance, with heat stability as a secondary requirement. Typical end uses include lighting bezels, interior trim panels, bumpers and fascias.
Typical values for a general purpose grade are listed below; filled, stabilised and speciality compounds will differ.
| Material | Density | Tensile strength | Service temperature |
|---|---|---|---|
| Polystyrene | 1.04-1.06 g/cm³ | 30-50 MPa | -20°C to 70°C |
| Acrylonitrile Butadiene Styrene | 1.04-1.06 g/cm³ | 30-50 MPa | -20°C to 80°C |
| Polycarbonate | 1.20 g/cm³ | 55-70 MPa | -40°C to 120°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.
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.
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.
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. {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.
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.
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.
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.
Our team supplies electronic plastic housings and enclosures to automotive customers worldwide, with samples, material certificates and full inspection reports available before mass production.
