Electronics and electrical buyers increasingly specify electronic plastic housings and enclosures instead of metal, wood or glass. Here is where they are used, why they work, and what to watch out for.
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 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; EMI and anti-static grades. Materials most often specified are PC/ABS Alloy, Polypropylene, Acrylonitrile Butadiene Styrene, Glass Filled Nylon, and the choice between them changes stiffness, temperature resistance, chemical behaviour and price.
In the electronics and electrical sector the decision is usually driven by flame retardancy and dimensional stability, with EMI control as a secondary requirement. Typical end uses include connectors, device housings, switchgear panels.
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 |
|---|---|---|---|
| Polypropylene | 0.90-0.91 g/cm³ | 25-40 MPa | -10°C to 100°C |
| Glass Filled Nylon | 1.36-1.38 g/cm³ | 130-190 MPa | -40°C to 150°C |
| PC/ABS Alloy | 1.13-1.15 g/cm³ | 45-60 MPa | -30°C to 110°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.
In the electronics and electrical 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.
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.
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.
