Few Guidelines to be considered in Design for Manufacturing

There are many factors to consider when designing for manufacturing (DFM Services) by injection molding. You must ensure that your product can be produced accurately and consistently, however, you may need particular features or parts that will require additional efforts by tool manufacturers. To ensure that your design is smooth and that the injection mold is successful, here are ten design guidelines to follow:

1. Keep it simple. The design is about simple products and clean lines that are functional. Simple shapes, lines and curves will make your design look modern and aesthetically pleasing.

2. Using standards when designing your product, do not specify odd-sized screws and hard-to-obtain materials. Designing with standard "ready-to-use" components in mind will keep your design efficient and affordable. People will want to use something that is easy to maintain, so make your design with the end user in mind.

3. Design for ease of manufacturing. Do not make everything a challenge for the toolmaker. Part of the product design is to create something that is pleasant for the customer and relatively easy to manufacture.

4. Avoid thin walls or anything that may deform during the cooling of your mold. The creation of a mold with thin spider web walls or chunks that will take a long time to cool will result in costly deformation and rejection, which leads to the need for a new design.

5. Avoid cuts. Think about where the line of separation will need to be. Avoid protrusions that get caught in the mold when it opens. If you can avoid them, try not to include threads in your design. They will limit the design in terms of where the separation line should go and increase the rejection change.

6. Small, intricate parts increase the chances of rejects and increase your production costs. When designing corners or other features that require a radio, look for the largest possible radius without compromising its design.

7. Design pieces that can be oriented. If your part is a component of a larger design, consider its ease of construction. If there is any piece that may become tangled or bent during the construction of your product, you may need to reconsider the design of your part.

8. Efficient union and fixation options. A good piece design will include fastening methods to other parts without the need for screws or glue.

9. Design components so that they can only be assembled in one way. Make the design of your piece easy enough for a child to build the final product. There should be no confusion about how your part fits into the overall design.

10. Designing for an aesthetically pleasing product that is functional and easy to produce can be a challenge, but it is a necessary part of the design process. Plastic injection molding is still the best method of mass production that exists today.
