Quality assurance

We are an ISO 9001:2015 and ISO 14001:2015 certified company.


Hydraulics allow no errors

Be it any machine or device, and hydraulics allow no errors. Therefore, the design and machining programming of ST-Koneistus products are the responsibility of experienced people who have received professional training.

In addition, we further develop the competence of our own personnel through training related to the employee’s job description.

ST-Koneistus is committed to developing its operations in accordance with the quality and environmental policy. Read about our quality and environmental policy.

How do we ensure the quality of your products?

We implement measurement practices mutually agreed with the customer and follow the tolerances set in the product approval.

We use new and modern measurement devices that record results wirelessly in an excel spreadsheet. We deliver the measurement reports to the customers as agreed with the delivery batch.

In addition, ST-Koneistus uses an extremely precise Mitutoyo Crysta-Apex S 9108 measurement device. Thanks to temperature compensation (16°C -26°C), the measurements can be performed already in production, which improves quality and saves time.
