A few key mold design strategies can go a long way in improving your mold building operations and customer support.
Using 3-D solids design makes it substantially easier to achieve standardization and synchronization across design and manufacturing, resulting in fewer errors, speeding up delivery, and obtaining more reliable results. Working in 3-D solids enables many of the manufacturing issues to be identified upfront, allowing the designer to detect potential collisions, verify correct shrink values and determine whether parting surfaces are manufacturable. With 3-D, a fully detailed and consistent model is maintained throughout the design and manufacturing processes, so changes can be quickly and reliably incorporated from design to manufacturing and assembly.
With a realistic view of the tool in motion built into their CAD environment, designers are able to prevent common errors and improve communication with customers.

Standardization goes a long way towards increasing the quality of work and reducing delivery time and cost. Creating a rich library of mold bases and related components that can be readily reused in new tools will streamline the design process and leave far less room for errors. Standard components and user-defined templates that can be applied with a single click will minimize time spent on repetitive tasks, promoting consistency across jobs and uniformity among designers.
There are still some unique characteristics to each mold, but if we can get to the point where 60 or 70 percent can be standardized or automated, then we are focusing our time on the high value added for the customer, Milling templates allows us to make only minor changes during the machining of a new part, which greatly streamlines the process. 
The success of a mold manufacturer boils down to its ability to deliver high quality products at the shortest possible time.
