Multi-reference filling machines are a great way to improve the filling process across multiple products and packaging types.
However, they do require a certain amount of change tooling to handle a range of packaging formats. To be effective as a multi-reference machine, the changeovers need to be quick and easy.

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
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.

Rear Filling vs. Front Filling for 2-Component Cartridges
When it comes to semi-automatic filling of 2-component cartridges, there are two commonly used methods: rear filling and front filling. Each approach has its own advantages, limitations, and best-use cases.

Investing in a New Filling Line: Key Considerations for Throughput, Flexibility, Set-Up, and Utilisation
When it comes to investing in a new filling line, the decision goes far beyond simply choosing the latest piece of equipment. It involves a strategic evaluation of current operations, future demand, and how best to optimise production efficiency across the board.
