Light Brown PEEK Smartphone Screen Fixture | Precision Cavity & Vacuum Channels

Tagged: CNC Milling PEEK PEEK CNC

We engineered a high-precision light brown PEEK smartphone screen assembly fixture for a leading display manufacturer. Machined from light brown PEEK, this fixture securely holds phone screens during alignment, bonding, and curing processes. The design features precision screen cavities, vacuum channels, and locating pins all machined from a single PEEK billet, ensuring consistent screen positioning and scratch-free handling.

Key Technical Highlights

Precision Screen Cavity: Machined to ±0.02mm tolerance, ensuring perfect screen fit and consistent positioning during bonding processes.
Integrated Vacuum Channels: Precision-milled vacuum grooves hold screens securely in place without mechanical clamps, preventing distortion or damage.
Scratch-Free Screen Contact: PEEK's smooth surface finish (Ra ≤ 0.6μm) and material softness prevent micro-scratches on delicate display surfaces.
Light Brown PEEK Selection: Light brown color provides excellent visual contrast against screen edges for easy manual placement and inspection.
High-Temperature Resistance: PEEK withstands elevated temperatures during screen bonding and curing processes without deformation.
Single-Piece Construction: All features machined from one solid PEEK billet, eliminating assembly errors and ensuring long-term dimensional stability.

Quality Verification

Full inspection performed using ZEISS CMM with 1.2μm repeatability. Cavity dimensions verified against master screen samples. Vacuum channel depth measured via optical profilometer. Flatness checked on granite surface plate. First-article inspection report and material certification included.
