the number of molding cycles is up to 500K, used for medium-sized production volume.

The advantages of plastic injection molding
1) Higher Efficiency
The use of injection molds for mass production is great for achieving higher efficiency. Once designed for a specific purpose based on a customers choice, molding process doesn’t take long. This makes it a lot more effective in mass production and also a lot more efficient in output rate.

2) It Has Enhanced Strength.
The use of additives such as fibre glass in plastic material is very common. These highly engineered compounded plastic materials carry characteristics of durability of its raw materials. And, there are thousands of different types of materials in the market to suit different needs.

On top of that, the density of plastic just as it is being molded gives it greater strength. Strong and durable parts are very much needed in the market place, and plastic injection molding gives you the flexibility that not a lot of other molding processes can offer.

3) Gives Products Detailed Features
The injection molds are a great way to give you mass-produce a good and detailed feature, and since they are subjected to high pressure. Thanks to this extreme and excessive-high pressure, it tends to provide great detail and design on all parts of your parts or products. Secondary processes can be saved such as texturing, and through 2K or 3K molding methods, you save a lot of labor costs on assembly and the finishings are a lot more impressive.

4) Making Simultaneous Multiple Parts
Another major advantage when it comes to the use of plastic injection molding is that you can actually simultaneously manufacture different parts within the same mold. One shot of the molten plastic produces different parts to be assembled. Consistency in colors for different parts, is also a great determinant in designing the mold this way.

5) Saves Cost.
Thanks to the automation in plastic injection molding processes, mass production most often leads to the lowering of manufacturing cost. Injection moldings are usually automated, and it is all done by machines, robots, and/or an operator for all the quality control and management. The automation helps with significant costs savings in the manufacturing process.

6） It Is Cheaper than Plastic Machining, and More Lasting.
It is a lot cheaper as mentioned and give you the best without having to pay a large sum of money. As we know, the initial creation of mold can be very expensive but with mass production, each parts will cost significantly lower than say, a metal part. It is actually not economical to make low volume parts with plastic injection molding due to the high initial cost of making a mold.

7）Global Usage.
Plastic injection molding is one of the most popular plastic producing processes around the globe. Anywhere you look, anywhere you are, you will see lots of products made through this process.

I agree with your classification. It’s very scientific.

In fact, the production size of injection molding determines the cost. I can understand your blog

You’re very professional in classifying it,actually it’s the same thing in real production

It makes a lot of sense to grade the number of injection molding cycles like this
