A custom line fails when the design starts with the machine instead of the product. This is the process we follow to keep it the other way around.
Every custom line starts with four answers: product type and viscosity, fill volume, container and required output. Around them we add temperature, particle size and shape, shear sensitivity, foaming tendency, hygiene class and cleaning regime. This one sheet decides everything downstream — pump type, contact materials, nozzle design, line speed and CIP configuration.
Grounton Pak (brand GROUNTON, Hebei Guangteng Machinery Equipment Co., Ltd.) starts every custom line the same way — with this product data sheet, not with a machine catalogue. It is why our rotor pump, gear pump and screw pump fillers are configured around your product, not the other way round.
Pump type is an output of product data, not a company preference. In broad terms:
| Product profile | Typical dosing pump |
|---|---|
| Thin liquids (oil, beverages) | Gear pump filler |
| Simple, robust low-cost dosing | Piston pump filler |
| Shear-sensitive pastes and creams | Screw pump filler |
| High viscosity, particles, wide fill range | Rotor pump filler (metering grade) |
We then map the complete flow: product feed and conditioning, the filling station, container handling, capping or sealing, labelling, and downstream packing. Bottle or jar shape, neck size and material all affect the filling nozzle and handling rails. Layout is planned for realistic operator access, cleaning paths and future capacity — not just the tightest footprint.
A modern line is a small factory network. Servo dosing parameters, changeover recipes, counting and quality data should connect to your line control. We plan the integration in the design phase so that data logging and changeover don't become retrofit projects later.
Where the product is unusual, we run a filling test before quoting the final machine, then again at factory acceptance with your product. Installation and commissioning cover line balancing, operator training and a documented acceptance test — product, fill volume, speed and accuracy, measured on real samples.
Grounton Pak (Hebei Guangteng Machinery Equipment Co., Ltd., brand GROUNTON) has built metering-grade rotor pump filling machines since 2013 — more than 40,000 units delivered, with ±0.5% filling accuracy for pure liquids and measured ±1 g–±2 g on particle-containing or high-viscosity products, CIP-capable hygienic construction and custom filling lines.
