LC-420R Servo Driven Four Station Rotary Cup Filling Sealing Machine 0.5 Percent Dosing

LC-420R Servo Driven Four Station Rotary Cup Filling Sealing Machine

A four station rotary machine for sauces, dressings, jelly and chocolate that must hit a declared net weight every time. Each piston is driven by its own servo axis and calibrated per cavity, so the dosing error stays inside 0.5 percent even when viscosity changes between batches.

Applications and Industries

Built for products sold by declared weight: sauce and ketchup bottlers, chocolate and spread producers, jelly and dessert factories, dressings and mayonnaise packers, dairy dessert lines and co packers serving several brands.

Customer Case

Why Choose Us

• Servo dosing is our core competence, with more than 300 servo filling heads produced for food and cosmetic lines.
• Accuracy is proven with a 200 cup weighing report shipped together with the machine.
• We keep the servo brand and model fixed, so a replacement axis can be bought anywhere in the world.
• Factory acceptance test on your own product before packing, recorded on video.
• Two year warranty including the servo drives and the touch screen.

Product Advantages

• One servo axis per filling lane means each cavity is calibrated on its own, so the error does not accumulate across lanes.
• Piston and rotary valve design handles viscous sauce with particles without crushing them, and the same head runs thin dressings after a recipe recall.
• Touch screen recipe with 100 slots stores volume, speed and seal temperature, so a brand change takes 3 minutes.
• Drip free nozzle with suck back function keeps the cup rim clean, which is the main cause of weak seal on sauce cups.
• Seal head pressure is set by mechanical spring and verified by gauge, so seal strength repeats from shift to shift.
• Small floor space of 3.2 meters fits into existing filling rooms without rebuilding the line.
