In electronics and electrical projects, plastic extrusion profiles is only acceptable when the paperwork is right. This article maps the standards, test methods and documents you should ask for.
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 plastic extrusion profiles 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 in-line printing and embossing; cut lengths from 50 mm; co-extruded soft and hard zones. Materials most often specified are High Density Polyethylene, Polycarbonate, Acrylonitrile Butadiene Styrene, Thermoplastic Elastomer, and the choice between them changes stiffness, temperature resistance, chemical behaviour and price.
In the electronics and electrical sector the decision is usually driven by flame retardancy and dimensional stability, with EMI control as a secondary requirement. Typical end uses include switchgear panels, device housings, battery holders.
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 |
| Polyvinyl Chloride | 1.38-1.45 g/cm³ | 40-55 MPa | -10°C to 60°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.
Ask for the certificate number and test report, not just a claim of compliance.
Ask the supplier to state the standard number, the test method and the result on the certificate. A test report without a standard reference is difficult to defend during an audit.
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.
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.
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.
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.
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.
Our team supplies plastic extrusion profiles to electronics and electrical customers worldwide, with samples, material certificates and full inspection reports available before mass production.
