Trim Overlay Compatibility — Broad Vehicle Coverage, Rapid Development

Unlike full replacement parts, trim overlays adapt to factory panel geometry, enabling faster development and wider model coverage.

Custom overlay development starts from 20 units per design. Send a reference panel or 3D scan file to begin — typical development is 3–4 weeks for stick-on and 4–6 weeks for dry carbon.

How Shasha Carbon Fiber Trim Overlays Are Manufactured

01

3Dスキャン & Mold Design

Trim panels are 3D-scanned and reverse-engineered into molds with under 0.1 mm deviation.

02

Ultra-Thin Hot-Press Molding

Toray 3K prepreg is molded under pressure to produce rigid shells as thin as 1.0 mm.

03

CNC Edge Profiling

5-axis CNC machines trim edges so panel gaps remain identical to OEM trim.

04

Adhesive Pre-Application & QC

Pre-cut 3M adhesive sheets are machine-applied, followed by panel fitment checks.

Carbon Fiber Trim Overlay FAQs

Are Shasha carbon fiber trim overlays real carbon or vinyl wrap?

Shasha trim overlays use genuine Japanese Toray 3K carbon fiber prepreg, not hydro-dip, vinyl wrap, or printed imitation weave. They are finished with Nippon Paint UV-clear coat and backed by a 2-year factory warranty.

What is the difference between dry carbon replacement and stick-on carbon fiber overlay?

Dry carbon replacement parts replace the original factory trim and require removal of the existing component. Stick-on overlays install over the factory panel with pre-applied 3M adhesive, making them faster, lower-cost, and ideal for e-commerce resale or group buys.

What is the MOQ for custom carbon fiber trim overlay development?

Stock trim overlay orders start from 5 units per SKU, while custom overlay development starts from 50 units per design. Stick-on overlays usually have a lower development barrier because they rely on surface geometry rather than structural engineering.

Can trim overlays be developed for any vehicle interior or exterior panel?

Many panels can be reviewed if a reference panel or accurate 3D scan is available. The team checks contour complexity, edge clearance, button or light interference, adhesive coverage, and suitability for dry carbon or stick-on format.

How do you keep stick-on carbon fiber overlays thin and easy to install?

Low-profile tooling and ultra-thin hot-press molding produce shells around 1.0–1.2 mm where suitable. CNC edge profiling and pre-cut 3M adhesive help each overlay align cleanly with the factory panel.
