Design and mold making:

Firstly, according to the market demand and product design requirements, the appearance design and structure design of the pen.

Then, according to the design drawings, the mold is made, which is the key tool of injection molding.

Injection molding:

The plastic raw materials (such as ABS, PC, etc.) are injected into the various parts of the pen under high temperature and high pressure, such as the pen holder and pen cap, etc.

After injection molding, demoulding and dressing are carried out.

Pen tip making:

The production of pen tip is relatively complex, requiring high precision processing equipment. Usually includes wire cutting, molding, grinding, polishing and other steps.

For the fiber pen, it also involves the fiber merging, heat setting, dipping, drying, foaming, grinding and other processes.

Assembly and commissioning:

Assemble the injection molded pen holder, pen cap and pen tip.

Debug after assembly to ensure normal function of the pen, such as smooth writing and good sealing.

Quality inspection:

Conduct quality inspection on finished pens, including appearance inspection, function test, etc.

Ensure product compliance with relevant standards and requirements.

Packing and Warehousing:

The products that pass the inspection will be packaged with labels and instructions.

It is then stored for shipment.

Plastic raw materials:

Such as ABS (acrylonitrile-butadiene-styrene copolymer), PC (polycarbonate), etc., used for injection molding pen components.

Metal raw materials:

Some pen products will use metal raw materials, such as stainless steel, aluminum alloy, etc., for the production of pen holder, pen holder and other parts.

Fiber raw materials:

For fiber pen tips, fiber raw materials, such as polyamide 6 fiber, need to be used.

Ink and ink:

Ballpoint pen, signature pen and so on need to use ink or ink as writing medium.

Other auxiliary materials:

Such as adhesives, solvents, lubricants, etc., play an auxiliary role in the production process of pens
