In sports and leisure projects, plastic nets and meshes 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 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 mesh 4 mm to 50 mm; weights from 30 g/m²; roll length 50 m to 500 m. Materials most often specified are Low Density Polyethylene, High Density Polyethylene, Polypropylene, and the choice between them changes stiffness, temperature resistance, chemical behaviour and price.
In the sports and leisure sector the decision is usually driven by impact absorption and light weight, with comfort as a secondary requirement. Typical end uses include protective padding, helmet shells, kayak hulls.
The table below summarises the values that usually decide the material choice.
| Material | Density | Tensile strength | Service temperature |
|---|---|---|---|
| Polypropylene | 0.90-0.91 g/cm³ | 25-40 MPa | -10°C to 100°C |
| High Density Polyethylene | 0.94-0.97 g/cm³ | 20-32 MPa | -50°C to 80°C |
| Low Density Polyethylene | 0.91-0.93 g/cm³ | 8-20 MPa | -50°C to 70°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.
The following standards are the ones most often referenced in this product category.
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.
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.
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.
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.
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.
Share your specification and quantity with us and we will recommend the most cost effective material, tooling route and packing method for your market.
