Servo-Driven Bottom-Up Filling Eyebrow Pencil Filling Machine with Dual 5L Tanks

Product Overview

The JPF-16 eyebrow pencil filling machine is a servo-driven hot filling line built for round and triangular cosmetic pencil bodies. Bulk material is drawn from two 5L stainless steel tanks and delivered through a bottom-up nozzle, so each cavity fills from the base upward and air escapes ahead of the bulk instead of being trapped inside the stick. Operators load moulds onto the preheating table, run the filling cycle, transfer the tray to the time-controlled cooling table and release finished pencils at the demolding station. Because the filling section and the demolding section are separate units, the filling area stays clean while one operator keeps several mould trays moving in parallel.

With a stated output of 45-50 pcs/min and a working volume range of 2-10 ml, this eyebrow pencil filling machine suits cosmetic factories that run several shades and several pencil formats on the same shift. Servo filling replaces the mechanical cam and air logic of older fillers, so the shot size is entered on the Mitsubishi PLC touch screen and stored as a recipe. Changing from a 3 mm eyebrow pencil to a 5 mm lip liner therefore becomes a matter of recalling a recipe and swapping the format parts, not re-tuning a cam train. Buyers comparing an automatic eyebrow pencil filling machine usually care about three things: shot repeatability, empty cavities and demolding damage. The dispensing strategy on this line addresses all three at the same time.

Key Advantages

• Bottom-up dispensing: the nozzle rises with the fill level, which limits empty cavities, air holes and shrink marks at the pencil tip.
• Dual 5L tanks with independent temperature control: the material and the heating oil are regulated separately, so a wax-based eyebrow pencil bulk stays stable while the jacket temperature can be adjusted without scorching pigment.
• Servo shot control: fill volume is set numerically on the touch screen and repeated without mechanical adjustment, which keeps weight spread narrow across a full tray.
• Atomized mould oil spray: a fine oil film keeps pencil surfaces clean and makes release predictable, cutting the manual wiping step between cycles.
• Time-controlled preheating and cooling: both tables run on timers, so the cycle is repeatable instead of being judged by feel.
• Two demolding methods: needle push for round pencils and air blow for triangular pencils, so one eyebrow pencil filling machine covers both product shapes.
• Temperature-indicating moulds: labels on the pencil moulds show the real mould temperature, which helps the operator confirm that preheating actually reached set point.

Applications

• Eyebrow pencil hot filling for wax-based and gel-based formulas in 2-10 ml stick volumes.
• Eyeliner pencil production where a fine, void-free core is needed for smooth application.
• Lip liner and contour pencil filling on the same line by loading the matching mould set.
• Under-eye highlight pencils and other soft cosmetic pencil formats with a low melting point bulk.
• OEM and private label projects that require short runs across many shades.

Why Buyers Choose This Configuration

A cosmetic pencil line fails in production for predictable reasons: air pockets at the tip, weight drift across a tray, damaged surfaces after demolding and colour carry-over between shades. The bottom-up filling method on this eyebrow pencil filling machine addresses the first two, the oil spray station and timed cooling address the third, and the twin tank arrangement with quick-release product paths keeps changeover between shades short. Buyers who produce eyebrow pencil, eyeliner pencil and lip liner on the same equipment typically place this line next to a capping and labeling station, so the filled pencils move to finishing without an intermediate storage step.

The line is assembled in a workshop that also builds filling, capping and labeling equipment, so the same engineering team that quotes the machine stays involved during commissioning. Documents shared with buyers include the electrical diagram, pneumatic layout, spare part list, operation manual and a video of the factory acceptance run on the buyer’s own bulk samples. That documentation package is what quality managers usually ask for before they approve a new supplier, and it is prepared before shipment rather than after arrival.

Frequently Asked Questions

Q: Can this eyebrow pencil filling machine run both round and triangular pencils?
A: Yes. The line is supplied with mould sets for both shapes. Round pencils are released with the needle push method and triangular pencils with the air blow method, and the matching demolding mode is selected on the control panel.

Q: How is the servo bottom-up filling controlled?
A: A Mitsubishi servo motor drives the filling unit while the Mitsubishi PLC manages volume, flow speed and the nozzle lift curve. Shot size is entered on the touch screen in millilitres and saved as a recipe, so a repeat order does not need mechanical re-adjustment.

Q: What bulk viscosities does the 5L dual tank system handle?
A: The oil-heated three-layer tanks are intended for hot melt cosmetic pencil bulk, including wax-based, gel-based and paste-type formulas in the 2-10 ml range. Material temperature and oil temperature are controlled separately, which matters for pigment-heavy formulas that are sensitive to local overheating.

Q: What is included in the delivery and documentation?
A: Standard delivery includes the filling section, the demolding section, the preheating and cooling tables, one mould set for the ordered pencil shape, spare seals, the operation manual in English, an electrical diagram, a pneumatic layout and a video of the acceptance run with your samples on request.

Installation and Support

The filling section runs on three-phase 380V and the demolding section on single-phase 220V, so the site only needs one supply arrangement for both units. Air consumption is 0.4 m³/min at working pressure, which most factory compressors already deliver. Commissioning normally takes one to two days with a technician on site or with remote guidance over video, and the acceptance run is filmed so the buyer keeps a reference of the correct cycle. Spare part kits for nozzles, seals and mould locating pins are shipped with the machine.

Matching the Line to Your Pencil Format

Choosing an eyebrow pencil filling machine starts with the pencil body rather than with the tank size. Measure the barrel diameter, the cavity depth and the tip profile first, because those three numbers decide the mould set, the nozzle travel and the preheat time. A 3 mm eyebrow pencil needs a shorter cooling dwell than a 5 mm lip liner, and a triangular body needs the air blow release instead of a needle push. Once the format is fixed, the eyebrow pencil filling machine can be quoted with the right mould set, and the same platform can be re-ordered later for a second shape. Buyers who plan to add eyeliner or lip liner to the range normally order the eyebrow pencil filling machine with two mould sets at the start, which is cheaper than a second shipment later.

The second decision is capacity. A single eyebrow pencil filling machine rated at 45-50 pcs/min covers most private label volumes, and a second unit can be added in parallel when volume grows. Because the filling section and the demolding section are separate, the eyebrow pencil filling machine can also be split across two work areas if floor space is tight.
