The success of a mold manufacturer boils down to its ability to deliver high quality products at the shortest possible time and the lowest possible cost. Following are some mold design best practices that will help you achieve these goals.

1. Think Process Not Features
All too often, companies invest in a new technology just to find out that their new “toy” merely moved their production bottlenecks from one stage of the process to another. To really make a difference in business outcomes, companies must first establish a streamlined process that covers all deliverables and milestones— from the initial price quotation to the finished product. Inputs and outputs for each step in the process need to be clearly identified, along with quality expectations and the value added to the finished product. Once the entire process has been laid out, specific technologies and methods can be considered based on their impact on the process outcome, not the latest bells and whistles.

  The design process is 30 to 40 percent faster than it used to be and as much as two to three times faster on some molds. The flow from design to manufacturing is much smoother, shortening our delivery dates, making us more efficient and improving quality. I know it has impacted our bottom line. We can take on more business, because we are not spending as much time in design.

  2. It All Starts with the Quote
Quoting is the lifeline of the business. It is also the first time the part data is being handled at the shop. Incorporating common design standards and strategies into the quoting process—for example, material shrinkage parameters, part rotation and tip positions, and what standard components are going to be used¬—will ensure the quote reflects how design and engineering will approach the job.

  The person performing tooling quotations at EIMO is an experienced designer of 20 years. When we receive an RFQ, we evaluate the data and look for anything that will cause problems with the tool manufacturing or could lead to cosmetic problems with the part, so we can provide immediate feedback to the customer,

3. 3-D or Bust
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.
  Nobody wants to look at a 2-D model anymore. The people on the shop floor want to see exactly what they’re building, and the customers want to see exactly what they’re getting. Some of the very large and extremely complex molds we make today have more than 800 components and can weigh over 40 tons. We probably couldn’t even handle these types of jobs in a 2-D environment,

 4. Concurrent Engineering
Concurrent engineering can drastically shorten mold design time, as multiple design tasks can be performed simultaneously. For example, one designer may work on the cavity side while another works on the core side or one designer can finalize ejection while another designs the manifold and hot drops or one designer is finishing waterlines while another begins pulling electrodes. Manufacturing and assembly work can start while the design details are still being worked out, further compressing product delivery times.

 Since there is no need for translation between design and manufacturing, changes in design are automatically updated and toolpaths are flagged to show any changes. Machine operators can view the toolpaths and clearly understand the production process, eliminating the need for excessive documentation. In the assembly area, toolmakers can access the data online to do preliminary checks and verify dimensions, saving valuable engineering time,

5. Repeatability Not Repetition
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.

6. Put Your Design in Motion
Designing a moving object in a static CAD environment is a challenge that mold designers have grappled with for ages. Nowadays, advanced motion simulation technologies provide designers with the benefits of complete visual representation of mold kinematics and comprehensive collision detection, including automated recognition for mold components like lifters, sliders and ejectors. 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.

Final Words
While these best practices have proven to help other shops, the key to your success is applying the strategies and processes that are right for your business. Remember, these are best practices, not silver bullets!
