Choosing the right electronic plastic housings and enclosures for medical and healthcare 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.
This guide is written for engineers, purchasers and project managers who need a practical answer, not a resin data sheet.
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 transparent windows and light pipes; bosses and snap fits; wall thickness 1.2 to 3.0 mm. Materials most often specified are Polypropylene, Acrylonitrile Butadiene Styrene, Glass Filled Nylon, Polystyrene, and the choice between them changes stiffness, temperature resistance, chemical behaviour and price.
In the medical and healthcare sector the decision is usually driven by biocompatibility and sterilisation stability, with full traceability as a secondary requirement. Typical end uses include IV sets and tubing, surgical instrument handles, implant trial components.
The table below summarises the values that usually decide the material choice.
| Material | Density | Tensile strength | Service temperature |
|---|---|---|---|
| Acrylonitrile Butadiene Styrene | 1.04-1.06 g/cm³ | 30-50 MPa | -20°C to 80°C |
| Glass Filled Nylon | 1.36-1.38 g/cm³ | 130-190 MPa | -40°C to 150°C |
| Polypropylene | 0.90-0.91 g/cm³ | 25-40 MPa | -10°C to 100°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.
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.
Work through these points in order and most specification mistakes disappear.

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.
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.
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.
Our team supplies electronic plastic housings and enclosures to medical and healthcare customers worldwide, with samples, material certificates and full inspection reports available before mass production.
