When it comes to concept creation or designing of the product using a plastic injection molding technique, the main objective is to create a technically accurate product/component that functions properly as well as being manufactured at a low cost.
Most of the plastics used in today’s design properties have the same features which were only thought to be in metals. Some of these plastics have high-performance capabilities more superior to metals such as durability and strength.
Plastic injection molding is used in a wide variety of industries such as medicine, aerospace, plumbing just to mention a few.
Plastic injection molding is slowly emerging as an essential cog in the wheel of manufacturing, for those who want to improve their product design using these techniques; read on this post to know more.
Selecting the right tooling
Injection molding is mostly synonymous with large volume production, there are different ways of making molds and 3D printing is most widely used. Even though the production of mold is quite affordable the only downside is your components will have rough finishes which may require secondary finishing.
The most common type of tooling is aluminum positioning itself as the go-to tooling technique between steel molds and 3D printing. But for aluminum, they don’t produce the same volume as steel and its best suited for 10,000-50,000 shots or up to 100,000 shots.
Picking the right material
Another vital factor that will enable you to get the most out of plastic injection molding is choosing the right material. When it comes to materials, you need to determine the mechanical properties that will be best suited for your parts or products.
Some of the questions that you’ll need to ask yourself are: How much weight is it going to hold? Transparency and lastly will it be used in high temperatures. This are some of the concerns that you need to raise.
With all the compiled information and data, it will narrow down the choice of materials that will get you the best results.
The design for moldability
When you want quality and consistent results, there are some set of requirements and regulations that need to be followed with regards to plastic injection molding. With mold creation, some features must be adjusted to allows the proper resin flow into the mold.
Allowing it to evenly cool which reduces chances of defects such as sink, knit lines, flash, and warping just to mention a few.
