It looks like just a strip of sandpaper glued to a stick, but a good nail file is a must-have tool for salons, nail techs, and beauty brands everywhere. What seems super simple is actually the result of a careful, step-by-step factory process that makes sure every file works perfectly and lasts long.
Felice beauty is based in Yiwu International Trade City, close to Ningbo and Shanghai ports. Shipping by sea or air is very convenient. We focus on nail art tools, especially nail files, buffers, foot files, fake nail tips, stainless steel tools, nail wraps, and decorations. With 14 years of experience and certifications like ISO, SGS, SEDEX, FDA, and BSCI, Felice beauty is a reliable partner for professional-quality nail files.
This article shows you exactly what happens inside the factory. We’ll walk through the seven main steps that turn basic materials into the nail files used by pros around the world.
The 7-Step Production Process
1. Picking the Best Abrasive Paper
Everything starts with choosing high-quality abrasive material. The most common types are aluminum oxide (very tough), silicon carbide (extra sharp but breaks easier), and zirconia alumina (great for heavy-duty work). Each type files differently. Grit number matters a lot. Nail files come from coarse 80-grit to super-fine 240-grit and higher. For example, 80 or 100 grit works best on acrylic nails or thick calluses. 180 or 240 grit is gentle enough for natural nails. Before we start, every roll of sandpaper gets checked. We look at grain evenness, backing flexibility, and waterproof coating to make sure it will perform well.
2. Gluing the Sandpaper to the Core
Next, the abrasive paper gets firmly attached to a core. The core can be PP plastic, PS plastic, real wood, or thick EVA foam. Wood feels solid and natural. Foam gives a softer, cushioned feel. We use hot-press machines with the right heat and pressure. This step is crucial. Weak glue means the paper peels off while filing. Good bonding keeps the file together for its whole life. Our popular zebra grey nail files and emery boards are perfect examples of strong, long-lasting lamination.
3. Cutting into Shape
Once the sheets are ready, we use sharp steel dies to cut them into the exact shape the customer wants—straight, banana, half-moon, mini, etc. Felice beauty offers full custom die-cutting for any brand or style. We can also adjust thickness here by adding more foam or board layers while keeping the file flexible. This lets salons and brands create unique files that feel good in the hand and match their look.
4. Trimming and Smoothing the Edges
After cutting, every file gets its edges cleaned and smoothed. Sharp corners are removed. Extra material is trimmed away. This is extra important for washable files. Rough edges can soak up water or hurt skin. Our black professional nail files, for example, have perfectly smooth edges that are safe even on sensitive natural nails.
5. Adding Logos and Branding (Private Label / OEM)
One of Felice beauty’s strengths is full custom branding. Everything can be made exactly how the customer wants. We always send samples first so you can check quality before big orders. You can choose:
- Grit combos (like 100/180) • Shapes (banana, block, etc.)
- Colors (zebra, pink, white, black)
- Logo methods (screen print, UV print, laser engraving)
Packaging can be fully branded too—from simple plastic sleeves to beautiful retail boxes and salon kits.
6. Quality Checks Before Packing
Every single batch goes through strict testing. We check:
- Even grit under a microscope
- Glue strength • Shape accuracy
- Flexibility and snap resistance
- How well it files after many uses
- Smell (to confirm safe, non-toxic glue)
Only perfect files move on to packing.This means fewer complaints and happier buyers.
7. Packing and Getting Ready to Ship
Finally, the files are packed exactly how the customer asked. Common options are 25-piece bundles, clear plastic sleeves, blister cards, printed boxes, or full salon starter kits. Every package protects the files from moisture and damage while showing off the brand nicely. We support custom shape, size, color, and packaging so you get exactly what your market needs.
