Solidworks 3D Modeling Software

BMD uses Solidworks software as our primary modeling and mold design software. We have versions from 2016 up to the most recent releases installed so we can work with older models as necessary or upgrade your existing models to the latest version to take advantage of the latest features of Solidworks for mold designing. We also have 3rd party add-ins from R&B Mold Design Products called Splitworks and Electrodeworks that we use in the design processes.

Single Cavity Production Quality MUD Unit

This MUD unit was designed and built by Jepson Mold Design and BMS Company. It utilizes a locking hydraulic cylinder, and rising slide to allow part ejection without excessive wear on the side action components.

1 + 1 Cavity Family Mold

This was a fairly large mold that made two halves of a feeding tray for an automation system company.

2 Cavity Syringe Mold

This design was for a three plate cold runner system, with plate timing devices to assure the proper mold opening sequence to release the runners prior to the syringes stripping off the back half cores for ejection.

1 + 1 Cavity Family Mold

Here is another example of a design for a family mold with lifters to eject the part and valve gate hot runner system integrated into the front mold assembly.

SPI Mold Classification

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.

Customer Mold Data

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.

Mold Specification Sheet

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.
