Injection Mold Design

When planning to initiate a mold design the first question to be asked is "What Type of Mold Do You Need". This questions allows the designer and the customer to determine the build quality required for the complexity of the part, the required mechanical actions in the mold and how many molded parts art needed for the foreseeable future. These SPI Classifications are the standard used in the plastics industry to do just that. You don't want to purchase a mold that is too large or too small in cavitation. Too large increases the cost per part dramatically. Too small and you won't meet your production sales requirements. JMD works with our customers to determine the best solution to their particular needs, understanding that getting the most profit from the molded parts with the least amount of investment or headache works best for all parties. The section following the PDF files has calculators that you can download to understand your cavitation needs as well as estimate costs and profits.

This downloadable and tab able PDF file allows the customer to give the necessary information to the designer to initiate the project by placing all of this information in one simple, and easy to follow document that beco9mes part of the project history. The more completely this information can be filled out as early in the project as possible will reduce delays in the design waiting for information to be given or prevent errors in communication that can have disastrous results in the process of completing the design.

Once the proper SPI Classification has been determined, this form (which is tab able when downloaded), includes all of the information needed to understand the requirements of the design project, and all the particulars of the mold that will be designed to be built. There are industry standards that are insinuated by the SPI Classification, but not all factors and features are laid out in the specification so this sheet allows developing a fuller understanding of exactly what the design will be.
