The injection molding tool, also known as the mold, is another critical element in the total quality process control chain. This relies on a quality-built tool for the application of the best part design and the best materials.
In order to produce plastic parts that meet customer requirements, the design and construction of the tool must be of the highest quality. The key to successful completion of this task is to keep in close contact with all individuals responsible for the design and construction of the tool.
These activities include sales, design, purchasing, tooling, and manufacturing, in various degrees. Quality parts and their manufacture should never be compromised by negotiating for a bargain tool price. Since over 60% of the quality of a part comes from the tooling, it should not be diluted.
As the part designer, you are responsible for ensuring the tool’s design and construction is done properly. This means the part designer is responsible for deciding which parts and thicknesses will be used.
The part designer should not rely on the tool designer to make these decisions, because the tool designer does not fully understand the end-use function of the product. For this reason, parts and tooling design departments must collaborate in order to achieve the highest quality finished parts.
Because of this, the part designer is responsible for making sure that all necessary information for tooling design is available to the tooling designer promptly before tooling begins to be designed. This will save time, money, and future parts production problems; it will also result in a successful and profitable program.
