For contract manufacturing projects that aim to produce a product, project cost includes the overall works in design, engineering, manufacturing, quality, project management, and supply chain management. Within each of these categories, work can be divided into many sub-sectors with even more specialty tasks that intertwine with each other. Management teams try to put a budget on the project based on their best estimate. However, there are still many gray areas in the details of each task where decisions need to be made based on skills and best known methods (BKM). Without doing so, this is where the Snowflake Effect can be seen.
Plastic is a widely used material in manufacturing, both in products and packaging. It is energy efficient and relatively easy to manufacture in comparison to alternatives. However, there are countless different types of plastics that are used in different types of application. In general, plastics can be grouped into two main families: thermoplastics and thermosets. The main difference between these two types of polymers is that thermoplastics soften and become pliable above specific temperatures (upon heating) and solidify again upon cooling, whereas thermosets always remain in a permanent solid state once they have been molded. Today we will look at the thermoplastic group.
DFM (design for manufacturing) is the process of designing your product with the goal of making it easy to manufacture. It is a critical manufacturing tooling design and process development step before making a brand new product. If done well, DFM will assure both quality and productivity. Here are 3 reasons why you must take DFM into account in your planning:
