Right Mold, Right Machine

A word of wisdom on putting the right mold in the right machine from RJG Consultant, Shane Vandekerkhof.

Making sure that the right mold is put into the right machine is something that could use a little more attention for a couple of reasons—one of which is the issue of machine performance. While working with many molders in the medical industry, one issue that we see time and time again is the question of barrel capacity.

A common issue with high cavity, small component medical molds is too much barrel capacity. In these types of molds, medical molders are typically forced to purchase a larger machine for tie bar spacing, which can lead to a barrel that is larger than necessary.

We typically recommend running shot sizes between 20 and 80—ideally 40 to 60—percent of the barrel capacity. In the circumstance of a larger barrel, however, machines often run well below the 20 percent mark. This can lead to potential problems that boil down to residence time. When running low barrel capacities, residence time on the material will typically increase, raising the risk of material degradation. Continue reading.

Recently Taken a Systematic Molding Class or Plan to Soon?

RJG has released a public version of our Decoupled Molding Workshop, designed to provide students with valuable hands-on machine time to reinforce the methodologies they have learned in the Systematic Molding class. Attendees will acquire the knowledge they need to dissect and rebuild a process using data-driven methodologies, then document the return on investment and reveal potential improvement areas using the current condition of the machine and mold.

Our next class will be held in Georgia this August. Students must have already taken Systematic Molding within the 6 months prior to the workshop. Click here for details.

The Processor of the Year award honors companies with superior achievement among plastics processors. We don't want to take all the credit, but would like to point out that Evco and all of the finalists are customers of RJG. Just sayin'.


Passed Master MolderTM I? Take It to the Next Level

Whew… you made it through part one, but don't stop now! Master Molder II will give you the knowledge to further improve your process and make better parts by utilizing cavity pressure control strategies to accomplish Decoupled III techniques.

This course covers the proper use of instrumentation and how to achieve process control solutions through the utilization of Decoupled III techniques. It also covers how monitoring techniques are used to detect and contain suspect parts and how to do accurate machine and mold qualifications.

You will leave the course with an understanding of the improvements Decoupled III provides for process repeatability and robustness. Click here for more details and upcoming courses.

Master Molder II gives one an understanding of mold processes and why we have the problems we do with consistency. I would recommend this course to anyone who wants to better themselves or further their career. -Charles Arnold, ITW Fastex
RJG is on Fire in the UK (in a good way)

In March of 2015, we completed the purchase of G&A Moulding in the UK. Newly rebranded as RJG Technologies Ltd., the addition now has three Master Molder Technicians (MMI), one certified Master Molder (MMII), and another employee that has spent several days dedicated to eDARTTM implementation training.

By the end of 2016, we expect to have a certified trainer, one additional certified Master Molder, and a full time customer support team. We currently have open positions for a trainer/consultant and regional account manager—we predict that business will be hot!
