Selecting the Right Liquid Filling Machine FAQs Part 3

Selecting the Right Liquid Filling Machine- FAQs

Filling method matters as much as the machine format. Volume-based, level-based, pressure-based, vacuum-based, and flow-meter-based systems each solve different product challenges, from thin foaming liquids to thick viscous products and high-value formulations that demand tighter accuracy.

10 Frequently Asked Questions

1. What is the difference between rotary and inline filling machines?
   Rotary machines move containers around a circular carousel and are built for speed. Inline machines move containers in a straight line and are usually better for flexibility and simpler setup.
2. What is a volumetric filler?
   A volumetric filler dispenses a preset amount of product into each container. It is useful when the goal is consistent fill quantity rather than visible fill height.
3. What is the difference between MAGFlow and MASSFlow?
   MAGFlow uses electromagnetic flow measurement and is best for conductive liquids. MASSFlow uses Coriolis mass measurement and is better suited for high-accuracy filling and non-conductive or high-value products.
4. When should a piston filler be used?
   Piston fillers are best for thick or viscous products such as lotions, creams, pastes, and similar materials. They are especially useful when gravity or simple flow-based systems are not enough.
5. What is an overflow filler?
   An overflow filler fills containers to a consistent visible level. It is commonly used for clear bottles and products where shelf appearance is important.
6. When is a gravity filler the right choice?
   Gravity fillers work well for thin, free-flowing liquids. They are simple, economical, and commonly used for low-viscosity products.
7. What does pressure gravity filling mean?
   Pressure gravity filling means the machine can use pressure or gravity depending on the product and application. It provides flexibility for lines that handle more than one liquid type.
8. What is a pressure filler used for?
   Pressure fillers are used when product needs positive force to move into the container. They are often chosen for foamy, carbonated, or faster-moving applications.
9. What is a vacuum filler?
   A vacuum filler uses suction to fill containers. It is a more specialized solution and is used in applications where gentle or controlled filling is helpful.
10. What is a monobloc filler-capper?
    A monobloc filler-capper combines filling and capping in one integrated machine. It saves space and can improve line efficiency by reducing transfer between separate machines.
