Home appliance buyers increasingly specify plastic rods and bars instead of metal, wood or glass. Here is where they are used, why they work, and what to watch out for.
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 plastic rods and bars 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 ground tolerance h9; round, square and hex profiles; diameter 6 mm to 500 mm. Materials most often specified are Polyoxymethylene, Polymethyl Methacrylate, Polyvinyl Chloride, Polyamide, 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 kettle bodies, refrigerator liners, control panels.
Typical values for a general purpose grade are listed below; filled, stabilised and speciality compounds will differ.
| Material | Density | Tensile strength | Service temperature |
|---|---|---|---|
| Polyoxymethylene | 1.41 g/cm³ | 60-70 MPa | -40°C to 100°C |
| Polycarbonate | 1.20 g/cm³ | 55-70 MPa | -40°C to 120°C |
| Polyamide | 1.13-1.15 g/cm³ | 60-85 MPa | -40°C to 120°C |
Polyvinyl Chloride is frequently the default selection here: PVC can be formulated from rigid pipe compound to soft medical grade by changing plasticiser content.
Typical home appliance users specify this product for the following jobs.
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.
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.
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.
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. 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.
If you are planning a new home appliance project, send us your drawing, annual volume and target properties, and we will come back with a material proposal, a tooling plan and a budget quotation.
