Polystyrene (PS / HIPS) and Acrylonitrile Butadiene Styrene (ABS) are the two most quoted options for home appliance plastic parts in home appliance 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 home appliance plastic parts 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 large panels over 800 mm; heat resistant grades above 100°C; thin wall packaging parts. Materials most often specified are Glass Filled Nylon, Polystyrene, Polycarbonate, Acrylonitrile Butadiene Styrene, and the choice between them changes stiffness, temperature resistance, chemical behaviour and price.
In the home appliance sector the decision is usually driven by heat resistance and noise control, with colour consistency as a secondary requirement. Typical end uses include refrigerator liners, washer tubs, vacuum housings.
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 |
| Acrylonitrile Butadiene Styrene | 1.04-1.06 g/cm³ | 30-50 MPa | -20°C to 80°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 home appliance service the difference shows up in impact strength 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.
Processing method drives both cost and performance, so it should be fixed early in the design.
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.
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.
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.
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.
Our team supplies home appliance plastic parts to home appliance customers worldwide, with samples, material certificates and full inspection reports available before mass production.
