Virtual Pre-Acceptance Uses Technology for Customer Success
Virtual pre-acceptance with our customer Hubbell Power Systems – Testing and demonstration of the new 968.700 Tv (S1) machine.
Our customer was extremely impressed with the teamwork and good spirits that were shown throughout the run-off event!
DESMA USA recently facilitated a very successful virtual pre-acceptance of a large machine and mold at our DESMA Fridingen factory together with our customer Hubbell Power Systems! This was a multi-day event with participation from multiple parties on both sides of the Atlantic.
The use of virtual pre-acceptance was driven by international travel restrictions. In normal times, such large projects involve an in person pre-acceptance event allowing the customer onsite access to the equipment tooling and all resources necessary for success. However in these challenging times, virtual pre-acceptance is the next best solution since business must go on.
In this case, our customer felt that while the virtual event may not quite have matched the in person experience, we were able to accomplish much more than expected in an efficient manner. Facilitation from the USA together with support of “Team Hollywood” (our in-house digital production team) and the men of the Fridingen machine acceptance team were all engaged in this activity. The use of multiple HD cameras, both static and mobile, online access to the machine control, and the ability to interact with the men running the system proved effective in demonstrating features and performance of this cutting edge machine and tooling technology.
We all look forward to getting “back to normal” with in-person events, but when that is not possible for one reason or another, virtual pre-acceptance events like this are perfect examples of using technology to great advantage!

DESMA helps customer revolutionize part production to achieve FOUR times throughput
“Our partnership with DESMA has revolutionized the way we run parts in medium to high volume activities.” - Precision Associates
Precision Associates, for over half a century, has been a leading manufacturer of top quality, custom rubber seals and other rubber products for a variety of markets. Their capabilities include close-tolerance, precision machined plastic and metal components. From O-rings to U-cups to square gaskets, Precision Associates molds essentially every type of rubber seal you can think of.
For nearly 60 years, Precision Associates used the same traditional methods and machines for compression, transfer, and injection molding of rubber materials. Precision Associates’ engineering team recognized the need to modernize their equipment in order to open up a new range of capabilities and increase their efficiency. After looking at several options, they chose to partner with DESMA on their first new injection molding press in 2018.
Key Selection Factors for DESMA:
Ease of use - DESMA’s injection screw and plunger system uses a unique method to allow for cleaning and maintenance that Precision Associates found to be very quick and efficient
Ability to work with existing molds - At the time of partnership with DESMA, Precision Associates had over 8,000 active molds. Replacing those to adhere to a new platform would’ve been prohibitively expensive and a major roadblock. DESMA worked to modify their standard injection press allowing them to run their existing tools on that new press, which was a huge win!
Customization for the task - Repeatedly, DESMA has worked to customize their solutions to fit the unique needs of Precision Associates. The first run of HCR Silicone (Gum Stock) didn’t work well as the machines weren’t designed for that soft of a material. DESMA built a custom materials delivery system for Precision Associate’s press that provided a path for this new material to work. DESMA also worked with Precision Associates to get a machine running in their ISO Class 7 Clean Room for special medical applications.
Upon receiving and onboarding their first DESMA machine, Precision Associates found they were able to produce 4 times the throughput of their existing machines, and at half the labor cost! These results were so incredible, that in less than 3 years, Precision Associates has gone from 1 to 9 DESMA machines, and have revolutionized the way they run parts in medium to high volume activities.
Precision Associates has been able to bid competitively and win several large projects that they would’ve been unable to secure using their conventional molding method pre-DESMA machines. DESMA machines have also enhanced their work on existing high volume projects by cutting labor which decreases costs for both Precisions Associates and their clients, while reducing the need for long overnight and overtime hours for their team.
DESMA continues to support Precision Associates with strong support, solid training procedures, and a partnership approach to work on custom needs as they arise. It's been a great success and a foundation has been laid for more machines and a long term relationship moving forward.
DESMA Automation - Full Turnkey Support
Investing in automation technology will improve molding quality and maximize efficiencies.
For the last few decades in the elastomer molding industry, there has been an increasing demand to introduce automation principles into typical molding operations to improve efficiency and eliminate traditional manual labor. In the late 1990s DESMA recognized this trend in the industry & began investing in complete turnkey support infrastructure for our customer base.
From initial concept support to final implementation & installation, our Project Engineering divisions located in the USA, Europe, and Asia have the resources available to manage projects of automated systems for even the most demanding molding operations.
Some of the more basic examples of automation include basic brush systems & mold plate manipulating technology. Single side shuttle tables, centerplate exchange systems, and sliding heating platen technology are examples of this basic automation. An investment in these technologies will improve molding quality & ergonomics, maximize efficiencies, and eliminate labor operations.
More advanced automation projects often include multi-axis robots, customized pick and place systems, automated trimming devices, and even conveyor transport technology. Our full-time project engineering staff located in Hebron, Kentucky can customize a solution specific to our customers’ needs. For each project, we do an in-depth analysis of the goals based on the technical requirements while also keeping in mind economical constraints that may be present. Once we have collaborated with the customer to share information, a tailored Project Analysis is then presented to the customer for their consideration.
In rubber, each automated project is unique. For a percentage of our projects, a customer acceptance runoff (or Factory Acceptance Test) occurs at our World Headquarters in Germany after the new injection machine is manufactured. For other domestic projects, this acceptance runoff takes place at DESMA USA in Hebron, KY - or in more basic scenarios, the runoff and acceptance can be executed when the press is delivered to the customer location. The acceptance runoff tests, system optimization, and in-depth training are the final steps to the implementation of our turnkey automated molding cells for our customers.

Vacuum in the Rubber Injection Molding Process is Critical to Success
The importance of vacuum in rubber injection cannot be overstated.
Vacuum is an often used but a commonly misunderstood technique in rubber injection molding. The main purpose of vacuum is to remove air entrapments during the injection and vulcanization process that occurs once rubber is packed inside an injection mold. This sounds simple in theory but to achieve good vacuum in a repeatable injection process is a bit more complex.
Vacuum is achieved by evacuating air and developing gasses inside the mold or mold cavity prior to and during the injection process. A properly designed mold will have strategically located vacuum connections and dump grooves to assist cavity filling without voids in the product. Often these vacuum locations, or the vacuum achieved at these locations is insufficient, improperly designed or in many cases hindered by an inadequate working vacuum pump system outside the mold.
A "near perfect" vacuum is considered 0.996 bar or 29.4 mm hg. Many times this is difficult to achieve due to poorly sealed mold plates or is caused by a variety of other factors. Proper vacuum is a function of both sound machinery maintenance, vacuum pump and vacuum line maintenance as well as a properly sealed mold plate and cavity design. DESMA USA's NAMC division considers vacuum a key criteria in any new project design phase.
Another way to achieve adequate vacuum in rubber injection molding is to utilize a vacuum chamber where the mold is placed completely inside a controlled environment. To remove air, a properly sized vacuum pump with an accumulator tank evacuates the air completely within the chamber (versus cavity only) prior to or during injection. Special features within the hydraulic circuitry of the press must be incorporated in conjunction with vacuum for optimum process stability.
DESMA has many years of experience not only in process development using vacuum, but also in the development of machinery and molds that require vacuum. Our DESMA Trainer, Walter Frick, has decades of experience in this subject. Walter offers several classes on rubber processing that touch on vacuum. These classes were designed for in person instruction but have been updated and are now available online.
