Injection Molding: Advantages & Disadvantages

injection molding.jpgToday, we’re going to talk about injection molding, and how it can be both a benefit and occasionally a detriment to any business. If you don’t know what it is, injection molding is one of the most used manufacturing processes in the entire world. It’s a very versatile method of producing parts and products, and it’s also very efficient.

Advantages

In general, injection molding is usually referred to as plastic injection molding. The plastic molding process has long been thought to be a fantastic option by industries across the globe. The effectiveness and low-cost nature of plastic molding mean that it’s very easy to implement. But, why is it so good? Let’s list a bunch of reasons.

Firstly, it’s fast. Cycle times aren’t slow, which means that more work can be completed in quicker times. It’s also very accurate, meaning that the work completed can turn out to be very precise in nature. Really complex designs are easy to create; that otherwise might have been far too expensive to manufacture.

Another major benefit is that you can use multiple plastic types all at once with the help of co-injection molding. You can also use fillers in the injection molds to enhance the strength of the part after it has been molded. There are lots of possibilities available with plastic moldings, making them a great choice.

Ultimately, in terms of finances, the automation aspect of plastic molding is what makes it so appealing. It only requires one operator to control the injection molding process. This cuts down labor costs to a considerable degree. It also helps to reduce manufacturing costs in a big way, adding up to some serious savings over time.

And finally, the waste that is made out of the process can be recycled. We all want to commit to a green lifestyle, and our business can certainly do that through this method.

Disadvantages

There honestly aren’t that many disadvantages for us to note about injection molding, but they do exist to some degree.

Let’s start with the most important one, and that is the restrictions that come with part design. You see, a mold tool is made in a specific way, and this means that you have to tailor your requirements to it. If you don’t do that, you’re not going to get the result you want. It means that some restrictions are placed upon you, and that could turn out to be a problem occasionally.

Also, if you’re looking to carry out the process yourself, it’s going to cost a lot of money initially. Injection molding machines are expensive things, and you also need the skill set in order to run it properly. If you’re outsourcing the responsibility, it’s not always easy to determine accurate costing.

Ultimately, however, injection molding is something that poses more advantages than disadvantages. There’s a reason why it’s so widely used in a variety of industries, and there’s no doubt that it will continue to remain popular for a long time to come.
