Customization
Made to order: density, thickness, colour and shape to your drawing. Die-cutting, CNC routing, lamination to film or fabric, slitting and adhesive coating all run in-house, so the part we quote is a finished part, not just a sheet. How a custom part is cut and routed explains what to send with the drawing.
Regular material: MOQ 1,000 m², lead time 15–20 days from order confirmation. Custom parts are quoted from the drawing. A4 samples are free, shipping included.
An anti-static crate is the container a static-sensitive part travels in – between production stations, into stores, and out to the customer. Where a standard plastic tote generates and holds a charge, a conductive crate drains it, so the components inside never see the discharge that would destroy them.
Features
- Stable anti-static performance: the conductive grade sits at 10³ to 10⁶ Ω and the dissipative grade at 10⁶ to 10⁹ Ω, so the crate can be matched to the sensitivity of what it carries.
- Performance that does not drift: the conductive filler is in the material rather than coated onto it, so the resistivity does not depend on humidity or wear away with handling.
- Load capacity: the crate is built to carry stacked component loads without the walls bowing into the parts.
- Impact and vibration resistance: protects contents through the handling a tote actually sees, not just the handling it is specified for.
- Chemical and temperature tolerance: resistant to moisture, corrosion and the temperature range of a normal production environment.
- Made to size: crates are produced to the customer's dimensions and can be divided to suit the part.
Applications
- Electronics assembly – boards, sub-assemblies and finished units moving between stations
- Semiconductor packaging and wafer handling
- Precision instruments – optical lenses and sensors in temporary storage
- Laboratory and biomedical sample handling
- Aerospace component transit
- Automotive electronics, including EV battery and control modules
Specifications for anti-static crate
An ESD part is specified on two axes at once: the mechanical grade that holds the component, and the surface resistance that drains static.
| Foam | Expansion | Apparent density | Single-layer thickness | Why this grade |
|---|---|---|---|---|
| IXPE, conductive grade | 8–20× | 50–125 kg/m³ | 0.1–15 mm | A permanent conductive or anti-static grade, so the crate is a tote that has to drain static while it protects the parts inside. Surface resistance: conductive 10³–10⁶ Ω; dissipative 10⁶–10⁹ Ω. |
| XPE | 15–25× | 40–66.7 kg/m³ | 3–15 mm | The mechanical base layer, where the part also has to hold a shape or take a load rather than simply cushion. |
| IXPE | 8–20× | 50–125 kg/m³ | 0.1–15 mm | Thin, fine-cell IXPE sheet, and the plain base of the conductive grade above: the conductive grade is the same sheet with a conductive filler added, so the expansion range is the same. |
Base material specifications are on the XPE, IXPE and IXPP material pages; finished products are on the XPE foam and IXPE foam pages. Tell us the load, the space available and the service temperature and we will confirm the grade against your drawing.
Why Choose Bofeng Foam
We supply anti-static crates to the customer's own dimensions, in conductive or dissipative grade, with conventional wall thicknesses of 3 mm, 4 mm and 5 mm and dividing arrangements to suit the part. The material and resistivity data are set out on the ESD foam hub, and the physics behind the resistivity bands is explained in the conductive foam and ESD guide. Where the part needs a cut cavity rather than a loose fit, the same material is supplied as a conductive foam tray.
Conclusion & Inquiry
Send the component dimensions, the weight to be carried and the sensitivity class, and we will confirm the grade and wall thickness. Contact us for samples or a quotation.
