Below we will try to introduce the pen manufacturing industry step by step.

Firstly, we should know the pen components & ballpoint pen parts’ names. Most of ballpoint pens will mostly have parts like pen barrel, pen clip, pen tip, thrust device, thrust tube, spring, reservoir, socket, ball & ink.

 

But there are lots of simple design ballpoint pens with quite fewer parts, these ball point pen parts names are pen barrel, pen end clip, reservoir, socket, ball & ink.

 

Secondly, we would like to talk about the manufacturing process.  Most of  ballpoint pen making process as below:
1. Making the ink: Large batches of ink are made in a designated area of the manufacturing plant.

2. Stamping and forming:
1). While the ink is being made, the metal components of the pen are being constructed.
2). The formed pieces are then cleaned and cut. They are immersed in a bath to remove oils used in the molding process.

3. Molding the housing:
1). The plastic components of the pen are constructed simultaneously with the Ballpoint Pen’s other pen pieces.
2). For pieces that have more complex shapes, like caps, ends, and mechanical components, injection molding is used.

4. Ink filling and assembly:
After the components are formed, the assembly can take place. Typically, the ballpoint is first attached to the ink reservoir.

5. Final assembly, packaging, and shipping:
The point and reservoir are then placed inside the main body of the pen. At this stage, other components such as the cap and ends are incorporated. Other finishing steps, such as adding coatings or decorations or performing a final cleaning, are also done. The finished pens are then packaged according to how they will be sold.

In this article, we would like to introduce more details about the ballpoint pens` plastic parts manufacturing.  As it`s most people want to know when entering the ballpoint pens manufacturing industry or business. As we know, most ballpoint pen manufacturers produce the ballpoint pen`s plastic parts themself and then bought the ball point pen refill from a big manufacturer.

So what ball pen manufacturing machines you may need if you want to produce the ball pens? The answer is plastic injection molding machines is the main pen maker machine. As it can be used to produce most of ball pen plastic parts like pen barrel, pen clip, pen tip, thrust device, thrust tube, pen end plug, cap, adapter, etc.

Ball pen making machines will include many machines to set up the pens manufacturing production line:
1. Plastic injection molding machine
2. Plastic injection molds
3. Plastic materials
4. Material hopper dryer
5. Material auto feeder/vacuum loader
6. Water tower/chiller

How the Spring Ballpoint Pen Works

The automatic ballpoint pen is a commonly used tool in daily study and office. Press the refill to extend and lock the ballpoint pen, and then press the refill to retract into the pen holder, which is simple and practical. How does an automatic ballpoint pen work?

Structural composition: The components of the automatic telescopic locking mechanism of the ballpoint pen include: locking parts, pressure rods, and guide rails, as shown in the following figure:

The upper and lower tooth columns of the automatic ballpoint pen (for the time being) are the upper tooth column that can be pressed by hand, and the lower tooth column that can be rotated inside. The meshing of the upper and lower tooth columns is incomplete, only the tip of the tooth is partially engaged, and the guide ribs behind the two engaged teeth are designed to slide in the same guide groove, and the lower tooth column is pushed down by the upper tooth column. After the groove, due to the action of the spring, the teeth of the lower tooth column will slide along the inclined surface of the teeth of the meshing upper tooth column, so that under the action of the inclined surface, the lower tooth column will turn an angle and slide to the other side. , it is pressed down, and this repetition can realize the function of the ballpoint pen. I don’t know if the expression is clear or not. It’s best to observe the ballpoint pen carefully to confirm my statement.

You can calculate plastic injection mold cost by adding together the initial and recurring costs in the formulas below. There is a range of factors that goes into the final injection molding cost, including:

For initial costs:

Startup Cost = tooling costs + mold and material setup time and labor (drying resin + hanging molds + arranging water lines and sensors + setting up cooling or gating systems + scrap rates)

Recurring costs:

Recurring costs = raw materials + piece price (setup fees + set scrap rates, 3-5% of total piece price + machine hourly rates, ~60% of final cost + plastic weight + mold maintenance fee + inspection requirements) + secondary operations + packaging + shipping

Initial startup costs are fewer in number, but they cost the most. Tooling costs include all of the factors that go into making the tooling for your parts, including the cavities and slides. Other one-time expenses are usually rolled up in piece price, including configuring the setup of your parts, and the time spent getting the molds and materials ready. This includes drying your resin, hanging molds, arranging waterlines and sensors, and setting up any specific cooling system or gating system. It will also include set scrap rates for purging the machines of previous plastics.

Recurring costs, on the other hand, include setup fees, raw materials, piece price, and any post-production requirements such as packaging or shipping. Setup fees are for the work to calibrate the machines when they’re first turned on- employees must run shots of plastic through the machine to get it working correctly. Raw materials include both plastic resins and additives. Not all parts require secondary operations, but some will need machining, sonic welding, marking, or other services. Often manufacturers will offer secondary services as an option. Packaging can range from the least expensive packaging used to ship the parts to you, up to end-user packaging.

Of all of these components of the final price, piece price is the most complicated. One of the most expensive factors in piece price is the set hourly rates for machinery; the time to form a part (made up of the injection, pack and hold, cooling, and ejection times) is one of the areas that must be best optimized. This is why mold cavitation, the amount of cavities that will create parts in each mold, is so important. There will also be a fee for the plastic weight, including both plastic that becomes parts and scrap plastic left over in the sprue and runners. Finally, mold maintenance fees will cover the cost of mold warranties, and additional inspection will also add cost.

Between runs, you’ll also incur some of the costs mentioned as one time costs above. Once a run is finished, manufacturers will clean and put your mold into storage with a crane or other equipment. Before the next run can start, the mold will have to be reinstalled in the machine, hooked back up to everything, and calibrated. You will also be charged again for purging other plastics from the system.  

Calculating these plastic injection molding costs before ordering will enable you to get a more accurate estimate of the potential budget and help you to weigh your options with injection molding vs. other manufacturing methods.

Is Plastic Injection Molding Cheap?

Plastic injection molding is cheap for large production runs and other specific circumstances. While startup costs involving the creation of tooling are relatively high, the process itself is budget-friendly enough to lower the overall piece price as long as production runs are large enough.

In situations where you need thousands or hundreds of thousands of parts, the relatively minor expenses of running the process can drive the price per part down to a few cents per piece. This is especially true for simpler parts, as they will require less complex, and therefore less expensive molds. More complex part molds will feature parts like side actions, hot runners, manually trimmed gates, and water cooling lines. Additional costs can be saved when waste plastic is ground down and recycled.

For situations in which there will be changes to the part design, however, injection molding will get expensive quickly, as each new or modified mold is a significant cost. Small part runs will also cost a great deal more per part, as will smaller quantities of plastics, as buying in bulk lowers the cost of raw materials (if bulk plastic is not used in a timely manner, however, this cost benefit can be swallowed up by storage costs).
