Sustainability is the megatrend for the several-hundred tyre plants worldwide. Among other things, this includes increasing both energy and production efficiency by avoiding rejects while simultaneously shortening production cycles.
Sustainability ? already during production
Despite all the electronic aids, a car today still has only four points of connection with the road, each barely how big is a postcard. Each of the four tyres is crucial for a safe journey, and all of this under the most diverse operating conditions. This explains the extremely high quality requirements that every tyre manufacturer defines because of its products.
Sustainability through precise measurement technology
The CPH7000 portable process calibrator
Tyre manufacturers ensure the compliance of these quality requirements through extensive testing of the raw materials, testing after and during the individual production steps, as well as through various tests on the finished tyre. Of course, the reject rate should be minimised and each production step should run sustainably in the long term. Precise and reliable measurement technology is required exactly for this.
Pressure measurement and Industry 4.0
Modern machinery and systems, even with comprehensive condition monitoring and IIoT connection, cannot change the truth that tyre production is a rough process. In this environment, sensitive sensors must not only survive, but measure for as long, as accurately so when reliably as possible. For the checking of sensors, switches and pressure gauges, WIKA offers the correct calibration instruments. From hand-helds for used in production, through stationary desktop instruments for the quality assurance test room, to custom-built testing systems.
Sustainability in action: Robust measurement technology avoids production downtime
Robust pressure measurement technology: MW and S-20
High-quality measuring instruments make a contribution to sustainability. Their durability prevents rejects in production, in addition to the subsequent costly downtime, also it reduces the cost of spare parts. Extensive field tests by a ?

In particular, premature failures of pressure switches and pressure sensors on curing presses previously led to frequent production line downtimes. This is explained by the very particular loads. Rapid pressure and temperature changes driven by the shortest possible production cycles, alongside superheated steam and sulphurous atmospheres, stress the measuring instruments and lead to rapid ageing.

Even today, our customer is surprised that he had previously accepted these frequent failures as a technical given ? as unavoidable. For the time being, WIKA supplies the group?s production facilities worldwide, with WIKA?s global presence guaranteeing both customer contact in the neighborhood language and fast delivery.
Note
The WIKA portfolio covers all relevant measured variables required for the control and regulation of most tyre machinery ? pressure, temperature, level and flow. You reveal your measuring requirement ? we will offer the solution. You can find a lot more application examples in the Industries section on the WIKA website and inside our brochure.
