As the automotive industry shifts toward electrification, the demand for high-fidelity dimensional control has never been higher. Our e-trunk frame checking fixtures are engineered to provide Tier 1 suppliers with absolute certainty in part-to-part consistency. By integrating global manufacturing standards with rigorous validation protocols, we help you eliminate assembly bottlenecks and ensure that every vehicle meeting the consumer reflects the highest level of craftsmanship.
Technical Engineering & Material Innovation
To address the challenges of EV lightweighting-such as the complex springback of thin-gauge stampings and the intricate geometries of aluminum die-castings-our fixtures utilize a hybrid material approach. We combine high-stability Alumec 89 aluminum bases with carbon fiber bridge structures to maintain thermal stability while reducing overall tool weight for easier handling. With a precision threshold of ±0.03mm for critical datums, we specifically target high-impact zones including seal tracks, lock-striker interfaces, and hinge mounting points. This level of technical rigor ensures that your components are ready for the most demanding Gap & Flush (S&F) requirements.

FAQ
Q: How do you ensure long-term dimensional stability for large EV frame fixtures?
A: We utilize a multi-stage Stress Relief (Aging Treatment) process for all base plates to prevent warping over time. Furthermore, all critical locators and pins are manufactured from high-frequency quenched tool steel or tungsten carbide to withstand thousands of cycles without precision loss.
Q: Is the fixture compatible with automated metrology systems like CMM or Blue Light Scanning?
A: Absolutely. Our designs include integrated Master Bushings and standardized coordinate systems. This allows your team to seamlessly transition between manual checking and digital data collection (CMM/Laser Scanning) for full-loop quality traceability.
Q: How do you handle rapid Engineering Changes (ECO) during the development phase?
A: We employ a Modular Insert Design. Critical geometry blocks are detachable, allowing for rapid updates if the part design changes. This saves you the cost of a full base rebuild and significantly reduces lead times during the pilot phase.
Q: What are your standards for international shipping and onsite protection?
A: We provide export-grade, fumigation-free wooden crates with internal shock absorption and vacuum-sealed anti-rust packaging. Every shipment includes a Third-Party CMM Calibration Report, a detailed User Manual, and a critical spare parts kit.
