Manufacturing high-quality plastic injection molded parts takes a lot of attention to detail. There are four key factors that determine if a large-volume project will go smoothly. They include:
Part Design, Tool Design and Build,
Material Selection and Manufacturing
Without a precise approach to each stage of the process, things can go wrong, and when they do, costs begins to rise.
In our eBook "How to Manufacture a Perfect Plastic Part", we review the most important aspects of each stage in the manufacturing cycle along with some helpful charts and diagrams.
We know that product designers and engineers are often overwhelmed with the long lead times in getting a part manufactured. By focusing on these four core factors, we hope to help you streamline the process.
First and foremost, the part must be optimized for manufacturability. Using the resources of a turnkey injection molder will help. Manufacturing design engineers are a great resource. They have often come up the ranks and began as tool builders. They understand how to apply part modifications that will improve the overall quality, appearance and manufacturability of a part.
There are some standard design benchmarks that must always be considered in the injection molding process. All part designs should have a uniform wall thickness, optimized rib and boss design and placement, as well as curved corners with consistent radii.
Sharp corners cause problems with melt flow and packing. Improper rib design and/or placement can cause weaknesses in the part wall. The same is true with bosses.
Our eBook provides illustrations and details on how these key critical design features can impact part quality and moves forward in the process straight through to the final step of manufacturing.
