A thorough discussion and evaluation of options are required to transform your customer’s request from the idea they present into reality. Although plastic injection molding is an efficient way to make plastic parts, there are different aspects to consider before choosing the right approach to assure steady production and a satisfied customer. There are many options, from resin to surface design, so I turned to Wunder Mold for more information about plastic molding. Here are some tips they gave me:

How to Choose the Right Surface
Surfaces are essential from a visual perspective and from the perspective of previous materials and production decisions. It is imperative to decide on the correct surface finish early in the planning process because it will have an impact on the rest of the design. Surface finishes can also vary depending on the materials you choose.
Textures also play a significant role in blending parting lines and creating undercuts. The texture is beneficial not only for aesthetic purposes but also for practical ones. In addition, it is essential to consider making room for gases to escape during the injection since this affects the grip and how well the paint sticks to the surface.
Levels of Thickness
During the process, it is imperative to keep the thickness level constant. Variations could negatively impact the process. An ideal range would be between 2-3 mm, but it is almost impossible to keep a steady stream.
Approaching Drafting
Parts are released from injection molds using a process called “drafting.”. This is done to maintain a steady flow without forcing them out of the mold, as well as to increase the longevity of the tools. For a fully textured mold, the degrees should range from 1 to 3. In this case, it is vital to have more drafts because it allows the part to be removed from the mold and helps maintain quality and tool utility in fast injection molding operations.
Material Selection
The right resin must be selected based on a variety of factors. You have to consider the final product, its use, and the environment it will be subjected to. What is the best type of material to use? Does it have to be elastic or firm? Can it withstand extreme temperatures? It’s also important to consider safety. An expensive and new product may not always be the best. You should maintain quality without increasing costs. The best thing to do is to find an engineer who is experienced in materials and present your idea to them. They can then decide which materials will work best for your application.

A Good Flow
It is necessary to simulate a constant flow while designing a part. An excellent, well-thought-out flow is critical to quality production, just as it is for drafting. Several elements in this simulation can be adjusted, including finding the best location for the gate, allocating water, and setting up runners. In general, the more complex the part, the more preparation and depth of simulation are required.
Finishes and Coatings
These should be minimized as much as possible. A coating or finish reduces the wear of a surface by adding a texture to it. Depending on the level of detail, finishes prolong the production process and increase the cost. Time, resources, and a minimum of complexity are all factors that have to be considered to produce cost-effective quality products.
