Paint Mixing Solutions

Paint mixing scales from Sartorius are designed for the requirements of automotive paint shops.  Thanks to their robust design and user-friendly interface, recipes can be transferred directly from the PC to the scale, where they can be efficiently managed. The intuitive operation and seamless integration into digital mixing systems enable precise and reliable paint production – directly at the vehicle workplace.

Paint mixing scales from Sartorius use high-precision weighing technology, which allows for an exact color formulation – a decisive factor in perfect color matching in the automotive paint sector. At the same time, they are robust and resistant to withstand the demanding conditions in workshops.

With their user-friendly operation and intelligent interfaces, Sartorius paint mixing scales bring a new level of convenience and functionality to modern automotive workshops – for efficient processes and reliable results. But it is also used in numerous other industries – including wood processing, marine and industrial coating.

If there is an overdose of a component during the mixing process, the Sartorius paint-mixing scale offers a correction mode to eliminate errors. This avoids unnecessary material loss – and saves time and money at the same time.

An incorrect weighing can be corrected as often as desired, as long as the total weight of the recipe does not exceed the maximum weight of the scale. The total filling quantity (liters) increases in the event of a correction! 

Yes, the factor calculation makes it possible to flexibly weigh in a smaller or larger quantity of a basic paint recipe – for example, 250 ml from a recipe originally calculated for 1 litre. In this process, the recipe is automatically adjusted accordingly so that the mixing ratios are exactly retained.

Explosion protection for a paint-mixing scale means that the scale is certified for use in potentially explosive atmospheres according to the regional directive.

In paint shops, especially in the automotive sector, solvent-based paints are often used. These can produce highly flammable fumes.

Depending on their certification, explosion-protected balances may be used in different danger zones. These zones are defined in accordance with regional guidelines and depend on how often and for how long an explosive atmosphere can occur.

Explosion-protected scales must be serviced taking special safety requirements into account. Maintenance may only be performed by certified technicians who are familiar with the applicable regulations. (see the safety information in the operating instructions)

EX certification, ISO/IEC 17025, OIML certification

Calibration of a paint-mixing scale should be performed regularly to ensure the accuracy and reliability of the weighing results – especially in areas such as automotive painting, where even the smallest deviations can affect color accuracy.

If a paint-mixing scale produces inaccurate measurements, the first thing to check is whether external influences such as vibrations, drafts or an uneven surface are the cause. Afterwards, a visual inspection for dirt or mechanical damage is recommended. If no obvious cause is identified, a calibration should be performed – ideally with certified test weights. If the inaccuracy persists, servicing by the manufacturer or a qualified service partner such as Sartorius is recommended in order to check the weigh cell or electronics.

• Verification is a legally prescribed procedure in which a weighing instrument is inspected by a state-approved body. A check is made as to whether it meets the requirements of the relevant calibration regulations. After a successful test, the scale receives a calibration mark and may be used in legal metrology (e.g. sold by weight).
• Calibration, on the other hand, is a technical inspection in which the measurement error of the balance is determined – without intervention or adjustment. It is used for quality assurance and is usually carried out on a regular basis, e.g. as part of the implementation of ISO certifications or internal QM requirements.
• Adjustment  of a scale is used to correct deviations between the actual measured value (actual value) and the desired value (target value). This correction is  called characteristic value adjustment and ensures that the balance measures accurately and reliably.
