How Whiteboard Markers Are Made in a Factory of Korea

Whiteboard markers have become an essential tool for classrooms, offices, and meetings around the world. Their smooth ink flow, easy reusability, and vivid colors make them a favorite for writing and presentations. But have you ever wondered how these markers are actually made? Let’s take a behind-the-scenes look at the fascinating process of making whiteboard markers in a factory.

1. Introduction to Whiteboard Markers

Whiteboard markers are specially designed writing tools that use erasable ink. Unlike permanent markers, their ink does not soak into the writing surface but stays on top, allowing it to be wiped away easily. The production of these markers involves a combination of precise engineering, high-quality raw materials, and strict quality control.

2. Raw Materials Used in Marker Production

Before manufacturing begins, factories prepare the essential raw materials:

• Plastic Resin – for the marker body and cap.

• Ink Solvent – usually alcohol-based, to allow quick drying.

• Pigments and Dyes – to give vibrant colors like black, blue, red, and green.

• Felt or Fiber Rods – used as ink reservoirs inside the marker.

• Marker Tips – made from polyester or acrylic fibers for smooth writing.

• above mentioned raw material is used for White Board Marker Making

3. Designing and Molding the Marker Body

The marker’s plastic body is prepared in injection molding machines. Tiny plastic pellets are melted and injected into molds shaped like cylindrical tubes. Once cooled, the plastic hardens and forms the marker’s barrel and cap.

4. Preparing the Ink

The ink is a crucial part of the process. In factories, ink is prepared in large scale steel body mixing tanks:

1. Solvents (like alcohols) are poured in.

2. Pigments and dyes are added to create the desired colors like black or blue etc.

3. Resins and additives are mixed to control ink thickness and erasability.

4. It is necessary The mixture is filtered to remove any impurities.

This results in a smooth, bright, and erasable ink perfect for whiteboards also which is packed in bottles for sale.

5. Inserting the Ink Reservoir

The ink reservoir, usually a felt rod or fiber stick, is dipped or injected with the prepared ink. The rod absorbs the ink evenly, acting as a storage system. This reservoir is then inserted into the plastic barrel of the marker.

6. Attaching the Writing Tip

Next, the writing tip is fixed at one end of the barrel. The tip is designed to deliver ink smoothly onto the whiteboard surface without leaking or drying too quickly. A small plastic ring holds the tip securely in place.

7. Assembly of Parts

The marker is now assembled by combining all its parts:

• Ink-filled reservoir inside the barrel.

• Writing tip at the front.

• A secure cap to prevent ink from drying out.

• Sometimes, a pocket clip is added for convenience.

8. Quality Control and Testing

Every batch of markers goes through strict quality control checks. Factories test for:

• Ink flow – ensuring smooth and even writing.

• Erasability – ink should wipe off easily without leaving stains.

• Durability – checking tip strength and barrel toughness.

• Safety – ensuring markers are non-toxic and safe for use.

9. Packaging and Distribution

Finally, the finished markers are packed into boxes, often in sets of four or more colors. They are then shipped to wholesalers, retailers, and eventually end up in schools, offices, and homes worldwide.

10. Conclusion

The making of a whiteboard marker is a blend of chemistry, engineering, and precision. From molding the plastic body to preparing high-quality erasable ink, every step ensures that the final product is reliable and user-friendly. The next time you pick up a whiteboard marker, you’ll know the fascinating process that went into creating this everyday writing tool.
