How are ballpoint pens processed?

A Ballpoint Pen is a pen that brings out the writing medium by rolling the ball at the front of the pen or refill. A ballpoint pen is a pen that uses a tiny rotating ball made of brass, steel, or tungsten carbide that releases ink onto the paper as it writes, eliminating the need for the writer to refill it from time to time, as is the case with fountain pens. The invention of the ballpoint pen increased the convenience of writing.

Ballpoint pen varieties, styles are different, in terms of quality and high, medium, low and other different grades, but from the category, can be divided into oil ballpoint pen, water-based ballpoint pen, neutral ballpoint pen and so on. Oily ballpoint pen is the first generation of ballpoint pen series products, from the batch put on the market, so far there have been more than 60 years.

After a long period of improvement, oily ballpoint pen production process is mature, stable product performance, long preservation period, writing performance is stable, has become a ballpoint pen products in the traditional product varieties, oily ballpoint pen ink used in the viscosity is higher, so the writing feel is relatively heavier; water-based ballpoint pen both fountain pens and oily ballpoint pen advantages, writing lubrication, smooth, uniform lines, is a more ideal writing tool; neutral pen Both water-based pen and oily ballpoint pen advantages, writing feel comfortable, ink viscosity is lower, and increased lubricating substances, the viscosity of the writing medium between water and oil, so more than ordinary oily ballpoint pen more smooth, is the upgrading of oily ballpoint pen products. The size of the nib of the neutral pen is roughly divided into two types: 1.0mm and 0.5mm.

1.Plastic Molding Mould Processing

According to the design parameters of ballpoint pen, shape, design and manufacture of pen cap, pen barrel, pen cap and other parts of the mold. Plastic plastic mold is the plastic processing industry and plastic molding machine supporting, give the plastic products to the complete configuration and accurate size. Mold is a tool for producing plastic products. It consists of several groups of parts, this combination of molding cavities. When injection molding, the mold is clamped on the injection molding machine, the molten plastic is injected into the molding cavity, and cooled and shaped in the cavity, and then the upper and lower molds are separated, the products will be ejected from the mold cavity through the ejection system to leave the mold, and then finally the mold will be closed again to carry out the next injection, the whole injection process is cyclic.

2,Processing of ballpoint pen parts using an injection molding machine

The injection molding machine is used to produce individual parts based on the molds made in the previous step. An injection molding machine is also known as an injection molding machine or injection machine. It is the main molding equipment to make various shapes of plastic products from thermoplastic or thermosetting materials using plastic molds. Injection molding machine according to the injection device and clamping device arrangement, can be divided into vertical, horizontal and vertical and horizontal composite type. Injection molding machine usually consists of injection system, mold closing system, hydraulic transmission system, electrical control system, lubrication system, heating and cooling system, safety monitoring system and so on.

3,Assembly of individual parts

The parts produced in the previous step are transported to the assembly plant, where they are assembled by operators and transported to the next department.
