Choosing the right electronic plastic housings and enclosures for water and wastewater treatment 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.
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 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 EMI and anti-static grades; bosses and snap fits; textured and soft touch finishes. Materials most often specified are PC/ABS Alloy, Polypropylene, Acrylonitrile Butadiene Styrene, Polystyrene, and the choice between them changes stiffness, temperature resistance, chemical behaviour and price.
In the water and wastewater treatment sector the decision is usually driven by drinking water approval and biofilm support, with corrosion free service as a secondary requirement. Typical end uses include filter housings, lamella plates, pipework.
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 |
| Polycarbonate | 1.20 g/cm³ | 55-70 MPa | -40°C to 120°C |
| Glass Filled Nylon | 1.36-1.38 g/cm³ | 130-190 MPa | -40°C to 150°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.

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.
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.
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.
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.
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.
