If you need a plastic component for a product you are making, you may have to contract with someone to make the parts which you need to assemble your product. There are a few methods around for making plastic parts including plastic machining and plastic molding. If you need a high-volume of plastic parts, then your best option is probably plastic molding.

Cost

The most expensive step of the plastic molding process is setting up the mold, which can cost thousands of dollars. Thus, if you are only making a few plastic parts, you probably don't want to go through all the expense of having a mold created. On the other hand, if you need thousands of parts over several years, then you should have a mold used. Once the mold is created, the manufacturer can use an automated machine to use the mold over and over to satisfy your demand for parts. Thus, labor-costs are minimal when creating parts from a mold, which makes molding highly affordable over the long run. 

Speed

Even if you have a computer-aided plastic machining facility, it takes time to remove plastic in order to shape exactly the part that you want. Thus, it can take time to machine parts. On the other hand, it takes a matter of seconds for plastic to set in a mold so that the mold can be emptied and readied to make the next piece. Thus, you can get a high-volume of pieces in a short period of time, which is ideal for when you need a rush order, or you simply need to keep up with demand. 

Sustainability

When you inject plastic into a mold, the process does not generate a lot of waste. Thus, you don't have to worry as much that you are harming the environment. Also, whatever waste is generated during the molding process can be recycled, which will decrease the demand for raw materials. This too will help you to make your design and manufacturing processes earth friendly. 

Flexibility

It is easy to add fillers during the the manufacturing process to increase the strength, flexibility, or other features of your plastic parts. Thus, if you have problems with one run of parts, you can give feedback to your manufacturer, who will then make adjustments to improve the quality of the plastic they churn out in the future.

All things considered, plastic molding is one of the most efficient processes on the market for generating high-quality plastic parts for use in industrial settings. In order to learn if plastic molding is the right choice for you, you should talk to someone in the industry to learn what they can do for you.
