AI Technical Summary

Technical Problem

Existing impact testing devices for recycled resin moldings are costly, complex, and unsuitable for evaluating the impact resistance of resin housings for electronic devices, with inconsistent evaluation results due to varying drop points and heavy weights, leading to increased size and complexity.

Method used

A linear actuator-based impact testing device with a striker connected via elastic bodies, allowing adjustable impact force through interchangeable springs and strikers, suitable for evaluating resin recyclability with consistent results.

Benefits of technology

The device provides an inexpensive and efficient method to sort recycled resin moldings by applying controlled impact forces, determining recyclability based on damage states, suitable for resin housings and electronic devices.
