Pros and Cons of Injection Molding | Should you use plastic injection molding?

Benefits

Relatively low unit costs. Due to the speed and efficiency of injection molding, labour costs, material costs and logistic costs can be reduced.

Produce detailed parts. The high pressure system can force the molten plastic into every crevice. Small details, logos, print or designs can all be produced with ease.

Consistent and high quality. Because of the high level of detail, molded parts will look identical giving a more professional feel to consumer products.

Injection molding is expandable. Since this system has been used for decades, there is no shortage of global injection molders. Therefore, you can save on freight costs or expand your geographical customer base if you produce units near the end users.

Downsides

Molds can be costly to produce. These molds are usually made overseas, can take weeks to build and cost hundreds of thousands of dollars.

Once a mold is made, it is hard to modify. Molds are made out of either steel or aluminum. If the product size needs to be increased, the mold may be able to be modified by removing some material. However, if there is a fundamental design change or the product is reduced in size, an entirely new mold is usually needed to be built.

Designing a product can be labour and time intensive. Because designing the mold correctly is so important, perfecting the product design is crucial. It would not be cost effective to take multiple prototypes to market in order to do consumer research. All consumer research, designs, material and engineering considerations should be done beforehand.
