Get Product Recommendation

Define the Product and Protection Requirement

Begin by identifying the product, its exact dimensions, fragile areas, accessories, transport and storage conditions, presentation needs, and the risks the case should address. “Protective” is not a complete specification.

  • Provide the product or a dimensioned model.
  • Define impact, compression, scratch, moisture, or organization targets separately.
  • State what evidence is needed for each claim.

Set the Case Shape and External Dimensions

The external case dimensions are derived from the product envelope, insert allowance, shell construction, zipper path, handle and hardware, and packing requirement. Irregular shapes may need a physical sample, scan, or detailed drawing.

  • Confirm orientation and access.
  • Allow space for cables, manuals, or accessories.

Internal organization may use cut foam, molded or assembled trays, fabric dividers, elastic retainers, mesh pockets, or removable parts. Define how the product is located, retained, removed, and presented.

  • Check tolerance and finger access.
  • Keep inserts from loading fragile product areas.

Buyer questions

What information is needed to develop a custom EVA case?

Send product dimensions, weight, accessories, protection target, preferred case shape, opening direction, insert needs, logo requirements, packaging, quantity, and market. Photos, 3D files, physical samples, or marked-up layouts can make the review faster.

How are foam inserts or trays confirmed?

Foam inserts or trays should be checked against the actual product, accessory list, finger access, tolerance, and packing method. A drawing can guide development, but the sample should confirm fit and usability before bulk production.

Can the shell, zipper, handle, and logo all be customized?

Yes. EVA cases can be developed with different shell structures, outer fabrics, linings, zippers, zipper pulls, handles, inserts, logo methods, labels, and packaging. Each visible and functional detail should be locked in the approved sample.

What does sample approval mean for an EVA case?

Sample approval means the case shape, shell, insert, product fit, zipper, handle, logo, packaging, and quality points are confirmed for production. It should not be based on product photos alone.
