These are the questions our engineering team hears most often when electronics and electrical buyers source plastic nets and meshes, answered in plain language with the numbers that matter.
Use it as a working checklist when you write your next enquiry.
This category covers a family of products rather than a single item. In practice a buyer defines plastic nets and meshes 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 width 1 m to 6 m; shade rate 30% to 95%; mesh 4 mm to 50 mm. Materials most often specified are Low Density Polyethylene, Polypropylene, High Density Polyethylene, 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 cable management, device housings, battery holders.
Typical values for a general purpose grade are listed below; filled, stabilised and speciality compounds will differ.
| Material | Density | Tensile strength | Service temperature |
|---|---|---|---|
| Polypropylene | 0.90-0.91 g/cm³ | 25-40 MPa | -10°C to 100°C |
| Low Density Polyethylene | 0.91-0.93 g/cm³ | 8-20 MPa | -50°C to 70°C |
| High Density Polyethylene | 0.94-0.97 g/cm³ | 20-32 MPa | -50°C to 80°C |
High Density Polyethylene is frequently the default selection here: HDPE combines toughness with chemical inertness, which is why it dominates pipe and tank markets.
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.
Work through these points in order and most specification mistakes disappear.
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.
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.
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.
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.
Share your specification and quantity with us and we will recommend the most cost effective material, tooling route and packing method for your market.
