Enhancing Production Reliability with Automated Quality Inspection

In modern manufacturing environments, efficiency alone is no longer enough. Consistency, traceability, and quality assurance are equally critical—particularly in industries handling adhesives and sealants. At Grunfeld, we recognise that true automation goes beyond filling; it extends to how quality is monitored, verified, and recorded throughout the entire process.

Void-Free Filling and Correct Piston Insertion

Void-Free Filling and Correct Piston Insertion

For many adhesive and sealant applications, ensuring void-free material within the cartridge is critical.

In single-component sealant applications, an air bubble can create a void in the bead, requiring retooling.

In two-component adhesive applications, an air bubble may cause a ratio imbalance, leading to soft spots in the bond.

Bulk Material Supply: Presses vs. Pumps

When filling or packing viscous products, bulk material is typically supplied to the filling line using either a hydraulic discharge press or a pump. Each method offers distinct advantages and limitations, and selecting the right system depends on both process requirements and facility layout.

Understanding Servo Dosing Systems: Advantages, Configurations, and Alternatives

Servo dosing is a term we use frequently, and for good reason. Put simply, servo dosing refers to a system where the dosing piston is driven by a linear actuator, which in turn is powered by a servo motor. This approach offers high levels of precision, repeatability, and control—key requirements in modern automated filling systems.

Why Machine Design Matters: Material Compatibility

When designing a filling machine, one critical factor often underestimated is material compatibility—specifically, the compatibility between the machine’s fluid-contact parts and the fluids being filled.
