The Design for Manufacturing review, or DFM, is intended to maximize the quality and performance of your manufactured parts while minimizing your production costs. This is helpful for large and small-scale manufacturing alike and is most effective when employed in the beginning stage of product design and production. Understanding more about how DFM is used and how you can apply it to your production will allow you to improve your manufacturing and maximize your return on investment.

  • Materials selection: When it comes to plastic injection molding, the materials you choose will make a huge difference when it comes to price, efficiency, and performance. You will need to consider the price of a given material as well as its availability and how it will behave for different applications. Learn more about materials selection at KASO Plastics.
  • Components: You should carefully consider the number of unique components included in your product; and remember, there is often room to reduce components for easier manufacturing. Your manufacturer’s engineering team can help ensure you simplify your design to minimize the necessity of additional components. This allows you to cut costs and manufacture more efficiently.
  • Wall thickness: When injection molded parts are manufactured on a relatively large scale, they must be made as uniform as possible. A slight variance in parts may cause problems so it’s important to keep everything consistent. It’s especially important for your plastic components to have uniform wall thickness. Variations in the thickness of plastic walls can lead to shrinkage and warping.
  • Gate location: It’s important to design your gate placement strategically for manufacturing. Since the placement of your gates will impact the way that melted plastic interacts with the rest of your mold, it’s a good idea to go over placement with your manufacturer’s engineers. As a general rule, you should place the gate in the thickest part of your mold since this is the part that will undergo the most stress.
  • Radius: The radius of your components’ corners will affect strength and durability. If the radius at the corner is too small, the component is far more likely to break under stress. You should make sure that the corner of your component is between 0.9 and 1.2 times the normal thickness of your part to prevent part failure.
