Tyre inspection - Import export

Tire mold cleaning is a concern for all manufacturers and retreaders. Tell us your problem and we might be able to help: we offer 30 years of experience in dry ice technology, and 10 years of presence on the market as supplier to the world’s major tyre manufacturers. Proper finishing of the tire bead surface so that it seals on the wheel; clear, crisp, and legible D.O.T. alpha-numeric characters, as required by law; crisp and precise brand logo and lettering, which are customers’ focus area for initial perception of a tire quality; mold vents and micro valves clear of rubber extrusions and “whiskers”; surfaces between mold sections free of residue build-up: no flash in the middle of tread patterns; segmented mold sections mating together even under extreme press squeeze; reduced mechanical loads on fasteners attaching the segments and sidewall rings to the press.

The dimensionCONTROL TWI 7303.I tire width inspection system is designed for profile width measurement in extrusion lines. This measuring system is based on camera vision technology involving two cameras inside one measurement box. These cameras are angle mounted to each other and operate according to stereo vision technology which enables high precision measurements in the whole calibration range.

Monitoring tire geometry i.e. the measurement of radial or lateral unbalance as well as side wall detection for bulges, constrictions, dents etc., is one of the most important inspections at the end of the production process. The TGI 8302.LLT system can be easily integrated while offering precise measuring results.

The profilometer thicknessCONTROL TCP8301.T-Offline is applied for sampling regarding the extrusion process of treads, side wall and inner liner material. The system offers measuring results in high precision and allows therefore an efficient production as well as a fully recorded quality control.

The profilometer of the thicknessCONTROL.TTP series accurately measures the thickness profile of tire tread or side walls during the extrusion process and enable therefore an efficient control during production as well as a fully recorded quality control.

The dimensionCONTROL TMWI 8302.LC system is suitable for the inline weight inspection of continuous running rubber profiles (tread pattern or sidewalls) for passenger and truck tires. Based on the force measurement principle, the inspection system uses two load cells which measure the deflection of the measurement conveyor. These sensor elements are attached to a massive construction, which ensures a long-term mechanical stability of the system. The measurement conveyor uses precise and balanced aluminum rollers with special surface treatment. This ensures a low deadweight, avoids influence of unbalance and eliminates material sticking. Data obtained from the load cells are processed in the implemented PLC cards which determine the measured weight mathematically.The software included offers a variety of measurement data processing, definition of design profiles, statistical analysis of measured profiles and diagnostic tools.

Micro-Epsilon tire uniformity and geometry machines measure force variation, runout, and sidewall appearance. Monitoring tire geometry i.e. the measurement of radial or lateral runout as well as side wall detection for bulges, constrictions, dents, week stamp etc., is the most important inspection at the end of the tire production process.

The rubber processing industry, as well as the tire production process is supported by Micro-Epsilon with a range of systems for inspection, monitoring and control of miscellaneous processes.

The system TCC 8303.I marks the running surface which is output after the extruder, inspects the colour lines for their completeness and measures the width of the running strip.

For tire production, tread strips are cut from the extruded strip material. The system TLS 8303.I is applied in the extrusion line to measure the length of the strips immediately after the cutting machine in order to ensure a secure production process in high quality.
