CRACK TEST MACHINE
The Crack Test Machine is a vacuum leak testing station for quality control of WC sanitary ware, designed to detect microcracks and leakage paths in multiple toilet configurations. Pneumatic sealing units close the product for a controlled negative-pressure test, while pressure-time evaluation and clear pass/fail indication support consistent inspection across changing product formats.

Per Year
Vacuum-Based Microcrack Detection
The sealed sanitary ware piece is subjected to negative pressure, allowing the system to identify pressure loss associated with cracks, holes or incomplete sealing.
Configurable Pneumatic Product Sealing
Pneumatic cylinders and dedicated closing units seal the main product openings, while the fixture arrangement can be adapted to different WC geometries.
Pressure-Time Acceptance Logic
The test cycle evaluates whether the required vacuum level is reached within the defined time and maintained through the holding period before issuing the result.
Integrated HMI & Visual Test Status
An operator control panel manages test initiation, while status lamps provide clear ready, pass and fail indications throughout the inspection sequence.
Multi-Format WC Test Envelope
The machine accommodates sanitary ware products including wall-hung, back-to-wall, P-trap, S-trap and one-piece WCs, with a documented maximum product height of 750 mm.
Integrated Pneumatic Control Architecture
Pressure regulation, pressure indication, vacuum generation and pneumatic actuator control are combined within the machine architecture, with automatic piston return at the end of the cycle.
