Pencil Filling Machine

Pencil Equipment

Cosmetic Pencil Filling Machine
for Eyeliner, Lip Liner & Brow Pencil Production

Pencil formulas are some of the most demanding to fill consistently — high pigment loads, temperature-sensitive wax blends, casings that vary by material and diameter. We've been building equipment for this category since 1999. Below is what we make, how each machine differs, and how to choose.

Our cosmetic pencil filling machines cover three distinct production types: conventional wooden-casing pencils, mechanical retractable pens, and liquid eyeliner cartridges. Each requires fundamentally different dosing mechanics — a one-size approach here is how you end up with inconsistent fill weights and wasted formula.

Every machine leaves our facility in Tainan after application testing with real cosmetic materials. If you're running a formula with an unusual viscosity profile or a casing size outside standard ranges, talk to our engineers before you spec — they've seen it before.

Application Scenarios

✏️

Eyeliner Pencil

Wax-based, kohl, gel-type — all require precise dosing temp & fill weight control.

💋

Lip Liner

Wooden or mechanical casing; color consistency across cavities is critical for retail SKUs.

🥷

Brow Pencil

Fine tip, harder formula blend — demands tighter cavity tolerance and consistent pressure.

💧

Liquid Eyeliner

Felt-tip or brush-tip cartridge filling; volatile formula management is the key challenge.

Model Comparison

Pencil Filling Machine — Key Spec Comparison

Not every machine fits every product type. Here's how the core models differ across the features that actually matter on a production floor — casing compatibility, fill speed, control system, and what formula types each handles reliably.

Feature	Wax-Core Pencil Filler (EL305)	Mechanical Pencil Injection	Liquid Eyeliner Filler (LS08-P2)
Target Product	Eyeliner, lip liner, brow pencil (wooden/plastic casing)	Twist-up lip liner, automatic brow pencil	Liquid eyeliner (felt-tip / brush cartridge)
Formula Type	Wax-based, pigment-heavy blends	Gel & wax, high-pigment	Volatile, film-forming liquid
Casing Compatibility	Wooden & plastic	Plastic retractable only	Cartridge (cotton-core & coreless)
Fill Units / Cycle	Multi-cavity (model dependent)	Multi-cavity (model dependent)	12 units simultaneously
Control System	Multi-stage parameter	Precision pressure control	PLC + HMI, parameter memory
Temperature Control	✓ Required for wax formulas	✓ Injection temp management	— Ambient, valve seal critical
Changeover Flexibility	High — handles multiple SKU types	Medium — casing-specific tooling	High — parameter memory per batch
Typical OEM Use Case	Mid-to-large scale color cosmetic lines	Specialty retractable pen lines	Dedicated liquid liner production

Specifications vary by model. Contact our engineers for exact fill speed, cavity count, and material compatibility for your specific formula.
