Gear quality control is conducted by our quality department, using the most technologically advanced mechanical and digital tools. We perform thorough checks, ensuring the highest quality of our products throughout the entire production cycle, from raw materials to dimensional accuracy, including heat and surface treatments. Through cycle mapping, we can monitor every production and processing process and all import stages.

Gear quality certification includes technical characteristics and specific dimensional and functional specifications for each product, ensuring maximum reliability and optimal performance.

Quality Gear: Pre-Delivery Controls

Italian production quality control

We are committed to providing effective and comprehensive solutions covering every aspect of supply chain management. Vendor inspection is a fundamental element in managing our supply chain, contributing to ensuring maximum quality, compliance, and reliability of our suppliers.

We inspect all incoming materials, evaluate the conformity of deliveries, and promptly report any non-compliant supply to the suppliers. The destination of non-compliant materials is continuously monitored and recorded, and the goods are managed according to the prescribed rules once they arrive in the waste warehouse.

We employ Statistical Process Control (SPC) to monitor our production processes, that allows us to measure and constantly control the quality of goods. SPC activates specific tools that will enable obtaining particular data regarding the quality of product measurements and process readings.

During the import phase, we can trace back to the reference supplier and all process stages through the production batch. Moreover, upon request, we include batch marking and the related customer code to make traceability even simpler and more effective.

Double quality control China/Italy

Thanks to our staff present directly on-site, we can carefully control the products manufactured by our selected partners in all production stages (with agreed control plans), including heat and surface treatments, up to the pre-shipping phase. We proceed with shipping to our headquarters in Italy only when the product is guaranteed to comply with international parameters.

Once the product arrives at our headquarters, it goes through the metrological control phase, where the quality control staff carefully examine every aspect, ensuring compliance not only with conventional parameters but also with supply standards agreed upon by the customer.
