Adhesive & coating

UBC (Underbody Coating)

In the automotive industry, effective and durable corrosion protection is imperative in the areas of bodywork and underbody. For this purpose, adhesives, sealants and insulating materials are applied with the highest precision.

For example, transition parts such as adhesive and welded seams are sealed before painting to prevent water from entering the vehicle interior at a later stage. In addition, visually appealing flanged seams have to be created. Thick material dosing, on the other hand, serves to protect against stone chipping. In all these applications, the materials, some of which are highly filled, are subjected to extreme stresses.

The challenge in this process was coming up with a metering technology that had the precision of the existing helical meters but wouldn’t be susceptible to the abrasive nature of the UBC material.

Basically for decades, this was a typical application for mechnical meters. These days there is a clear wind of change using by using state of the art Coriolis mass flow meters.

Typical flow rates:

  • 0,3-10 g/s (up to 20 g/s)
  • 0,75-30 g/s (up to 45 g/s)

Advantages:

  • Low to high pressures
  • Exotic materials available
  • Excellent zero stability
  • High turn down
  • Frequency output mimics turbine and PD meter output
  • Extremely fast and highly accurate dosing cycles
  • Assurance Factor feature, comprising meter self diagnostics
  • Maintenance free, no drift, no moving parts
  • For low flowrates very small footprint
  • Leight weight

 

Adhesive coating (shock absorber)

Advantages:

  • Wear free
  • Frequency output mimics turbine and PD meter output
  • Extremely fast and highly accurate dosing cycles
  • Assurance Factor feature, comprising meter self diagnostics
  • Maintenance free, no drift, no moving parts
  • For low flowrates very small footprint
  • Leight weight

 

To measure the flow rate of an adhesive coating, commercially available positive displacement meters were previously used to mix the filler with a powder component. However, due to the powder component, the meters wear out and the reliability systematically deteriorates. The expected accuracy was no longer achieved and the end product did not meet the standard required by the car manufacturer. A solution was sought to solve this costly problem quickly and efficiently.

A wear-free Coriolis mass flow meter meets required accuarcy and quality standards for this crucial application. A self-monitoring system (assurance factor) indicates the current status of the mass flow meter at any time. This is done via a clearly visible red, yellow, green display. In this way, the operator can quickly see whether his coating mix is working properly.

Surface coating

Paint and Hardener mixing systems for high and low pressure applications.

They can be used in manual and automatic processes for fast colour changes, as well as easy rinsing. This reduces the consumption of resources. The media is measured continuously and accurately, even if the viscosity of the material varies. Typical fluids processed are 1K, 2K or 3K materials, for water- and solvent-based coatings.

Available for very low flow rates. As a special feature our Coriolis Mass Flow meter euqipped with a self-monitoring system (assurance factor) indicates the current status of the mass flow meter at any time. This is done via a clearly visible red, yellow, green display. In this way, the operator can quickly see whether his coating mix is working properly.

Advantages:

  • Low to high pressures
  • Exotic materials available
  • Excellent zero stability
  • High turn down
  • Extremely fast and highly accurate dosing cycles
  • Assurance Factor feature, comprising meter self diagnostics
  • Maintenance free, no drift, no moving parts
