Polystyrene (PS / HIPS) and Acrylonitrile Butadiene Styrene (ABS) are the two most quoted options for electronic plastic housings and enclosures in food and beverage projects. Both are widely available, but they behave very differently once they are in service.
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; textured and soft touch finishes; EMI and anti-static grades. Materials most often specified are Acrylonitrile Butadiene Styrene, Polypropylene, Polycarbonate, Polystyrene, and the choice between them changes stiffness, temperature resistance, chemical behaviour and price.
In the food and beverage sector the decision is usually driven by food contact compliance and migration limits, with seal integrity as a secondary requirement. Typical end uses include beverage bottles, dairy tubs, takeaway trays.
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 |
| Polystyrene | 1.04-1.06 g/cm³ | 30-50 MPa | -20°C to 70°C |
| Glass Filled Nylon | 1.36-1.38 g/cm³ | 130-190 MPa | -40°C to 150°C |
Polystyrene is frequently the default selection here: HIPS is the default thermoforming sheet for food packaging and appliance liners.
Polystyrene grades offer rigid and glossy, while Acrylonitrile Butadiene Styrene brings high impact toughness. For food and beverage service the difference shows up in creep and in the long term behaviour under load.
The practical decision usually comes down to the service environment: temperature, chemical exposure and expected lifetime.
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.
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 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.
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.
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.
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.
Share your specification and quantity with us and we will recommend the most cost effective material, tooling route and packing method for your market.
