Single Nozzle Hot Filling Machine (Tank Lift Up/Down): Precision Hot Pouring for Modern Cosmetic Production
In today’s competitive cosmetics and personal care market, manufacturers face increasing pressure to deliver consistent quality, precise dosing, and efficient production—all while working with temperature-sensitive, wax-based formulations. Whether you produce lip balms, deodorant sticks, sun sticks, body butters, or herbal balms, your filling equipment must do more than simply dispense product. It must protect formulation integrity, minimize waste, and integrate smoothly into your production line.
The JSFL Single Nozzle Hot Filling Machine (Tank Lift Up/Down Model) from Shanghai GIENI Industry Co., Ltd is purpose-engineered to meet these exact challenges. Combining servo-driven piston technology, automatic tank lifting, and full-path heat retention, this machine delivers industrial-grade reliability for small- to medium-scale cosmetic filling operations.
Why Tank Lift Up/Down Matters in Hot Filling
Traditional hot filling machines rely on fixed nozzles or manual tank adjustments. These approaches introduce multiple risks:
-
Wax solidifies in the nozzle during pauses
-
Air pockets form inside containers
-
Drips and stringing cause messy molds
-
Frequent cleaning increases downtime
GIENI’s tank lift system solves these problems by moving the entire filling assembly vertically. During operation, the tank lowers so the nozzle can dive deep into containers, releasing product from the bottom upward. This technique:
-
Eliminates air entrapment
-
Produces clean, uniform fills
-
Reduces post-fill trimming
-
Improves surface finish quality
Once filling completes, the tank retracts upward, preparing for the next cycle without dripping onto the conveyor or molds.
Engineered for Wax, Balm, and Stick Formulations
The JSFL machine is optimized for hot-pour applications, especially where wax content exceeds 30%. Common applications include:
-
Lip balm tubes & pans
-
Deodorant sticks
-
Sun sticks / SPF sticks
-
Herbal balms
-
Body butters
-
Solid perfume
-
Cleaning balms
Each of these products demands tight temperature control and precise dosing. Even a ±0.2g deviation can impact product performance, regulatory compliance, and customer satisfaction.
Servo-Driven Piston Filling: Accuracy You Can Measure
At the heart of the JSFL is a Mitsubishi servo-driven piston system. Unlike pneumatic fillers, servo motors deliver:
-
Repeatable shot accuracy (±0.1g at 5g fill)
-
Smooth acceleration and deceleration
-
Programmable dive depth and retract speed
-
Minimal mechanical vibration
For manufacturers, this translates directly into lower material waste and higher profit margins. Over a 100,000-unit production run, ±0.1g accuracy can save hundreds of kilograms of expensive active ingredients.
Four Programmable Filling Modes
Different products require different filling behaviors. The JSFL offers four selectable modes via its Weinview touchscreen HMI:
-
Diving Filling – Nozzle submerges into container; ideal for wax and thick balms.
-
Fixed Position Filling – Nozzle remains stationary; suitable for shallow pans or jars.
-
Continuous Filling – Non-stop dispensing; used for bulk filling or open molds.
-
Stop Filling – Programmed pause/resume; useful for multi-layer products.
These modes allow a single machine to handle multiple SKUs without mechanical retrofitting.
Heated Tank, Valve, and Nozzle: No Cold Spots
Temperature consistency is critical in hot filling. The JSFL features:
-
20L dual-layer tank with electric heating jacket
-
Integrated mixing blade for uniform heat distribution
-
Vacuum function to remove air before filling
-
Heated valve block and heated nozzle
All product-contact surfaces use SUS316L stainless steel, ensuring corrosion resistance and compliance with cosmetic GMP standards. The heated pathway prevents premature solidification, nozzle clogging, and inconsistent flow rates.
Sanitary Design & Easy Cleaning
Cosmetic manufacturers must balance speed with hygiene. The JSFL addresses this with:
-
Mirror-polished 316L surfaces
-
Quick-disconnect fittings
-
Minimal dead legs in product path
-
Tool-free disassembly for cleaning
For contract manufacturers running multiple formulations per day, cleaning time directly affects profitability. The JSFL’s sanitary design reduces rinse-out waste and shortens changeover cycles.
