Intro:

We developed a fully automated testing bench designed to evaluate the mechanical resistance of ovens and microwaves, based on the materials used and the manufacturer’s strict requirements.
The purpose of the project was to verify controlled impact behavior by simulating collisions under perfectly repeatable and monitored conditions.

System Description

The equipment allows positioning the oven on a mobile platform that climbs a ramp to a predetermined height, calculated according to the desired impact speed.
The operator sets the parameters directly from the HMI interface, selecting the collision speed based on the applicable testing standards.

Based on these settings, the system automatically calculates the ramp angle and optimal height, lifting the platform using PLC-controlled motors. When the test is triggered, the oven enters a controlled free fall, reaching the exact speed configured from the HMI.

Key Features

  • Automatic impact speed setting directly from the HMI
  • Dynamic calculation of ramp height and angle based on user-defined parameters
  • Full PLC control of the lifting motors and platform locking mechanisms
  • Real-time monitoring of position and safety sensors
  • Intuitive interface with automatic parameter saving for repeatable tests.

This comprehensive functionality guarantees consistent, high-quality testing results that fully support the client’s quality assurance processes.

Full Implementation

Our team handled the entire electrical and automation side:

  • complete electrical cabinet and schematics,
  • PLC and HMI software developed from scratch,
  • full integration of sensors and actuators,
  • optimized control logic for maximum accuracy and safety during tests.

For the mechanical section (ramp, metal frame, and impact structure), we collaborated with a specialized team and trusted partners we frequently work with on similar projects — ensuring a robust, precise, and fully customized assembly that meets all client requirements.

Results and Benefits

By implementing this system, the client obtained:

  • a significant reduction in testing time thanks to full automation,
  • elimination of human errors through PLC control and continuous monitoring,
  • the ability to reproduce identical impact conditions for comparable, standardized results,
  • enhanced operator safety through acoustic and visual warnings,
  • high flexibility, with fast adaptation of tests to different product models or specifications.

A fully automated testing system capable of reproducing precise and safe impact tests, featuring complete HMI control, integrated dynamic calculations, and an intuitive interface.The project demonstrates our ability to deliver complex, customized, and fully integrated solutions — from concept to complete implementation.
