Precision Cavity & Structural Design

Earcup & Headband Support: Custom-contoured cavities isolate the main frame, protecting sensitive leather, foam, or glossy surfaces from friction and pressure.

Microphone & Cable Clearance: Dedicated clearance areas prevent flexible boom mics, cables, and inline controls from bending or interfering with the main body.

Integrated Accessory Compartments: Separate pockets keep charging cases, USB cables, adapters, and manuals organized and away from the headphone to prevent scratches.

Outer Box Fit: Designed according to internal box dimensions to prevent internal movement and carton bulging.

Targeted Headphone Applications

Wireless Headphones: Accommodates headphones alongside charging cases, USB cables, and user guides

Over-Ear & Studio Headphones: Provides heavy-duty, multi-point support for larger earcups and curved headbands.

On-Ear & Compact Models: Low-profile designs that maximize internal space without sacrificing protection.

Gaming Headsets: Multi-cavity layouts designed for complex frames, boom microphones, splitters, and bulky cords.

E-Commerce & DTC Packaging: Ruggedized structures engineered to pass drop tests and transit vibration standards.

Quality Control & Product Fit Verification

Outer Dimensions: Caliper/CMM verified against CAD files to ensure exact outer box compatibility.

Cavity Precision: Inspected to maintain specified clearance around delicate surfaces.

Physical Fit Testing: Verified using actual headphone samples for optimal insertion and removal force.

Surface & Edge Quality: Checked for smoothness, clean edges, and absence of loose fibers.

Warpage & Stability: Tested post-drying to ensure trays sit completely flat.

Transit Testing: Evaluated as a complete packaging system (Box + Tray + Product) under drop and vibration conditions.

FAQ

Q: Can the inner tray be fully customized for non-standard headphone shapes?

A: Yes. Trays are engineered directly from your product's 3D CAD files or physical samples to fit unique contours, folding mechanisms, and asymmetrical frames.

Q: Is molded fiber strong enough to replace plastic or foam packaging?

A: Yes. With proper structural ribbing and wall thickness design, molded fiber provides excellent shock absorption, structural integrity, and drop protection for consumer electronics.

Q: What information is required to get a custom quote and CAD proposal?

A: Please provide 3D files (.STEP or .IGS format), product weight, accessory dimensions, internal dimensions of your outer box, target packaging quantity, and material preference.

Q: What is the standard lead time for prototyping and mass production tooling?

A: Prototype samples are typically completed in 5 to 7 business days following CAD approval. Production tooling and mass manufacturing generally take 15 to 20 business days depending on order volume.

Q: Are custom colors or surface coatings available?

A: Yes. Standard options include natural, white, and black. Custom color dyeing and anti-static or water-resistant surface coatings are available upon request for production orders.
