DESFEED - The Flexible Silicone Feeding Solution

A stand alone feeding solution to compliment injection molding. 

For applications which require the injection molding of silicone (HTV – High Temperature Vulcanization / HCR – Heat Cured Rubber) DESMA offers a flexible material feeding solution named DESFEED

DESFEED is a stand-alone device which delivers the raw material to the screw of the elastomer injection machine where it is further processed and injected into an injection mold. Utilizing an electrically driven screw type positive displacement pump and a high pressure feeding hose, DESFEED takes the HCR/HTV raw material (blocks or “pigs”) and meters it to the opening of the injection unit screw.  

DESFEED is truly unique in that it is a portable system which can easily be connected and disconnected from an injection machine.

To use, connect the electrical power to the unit, the feeding hose , and a signal plug to the injection machine and it is ready for operation. The ease of connection makes it possible to easily and quickly move one DESFEED unit between multiple rubber injection molding machines.

DESFEED is best suited for HCR / HTV materials with lower viscosity.

Servo package now available for DESMA Alpha and Sigma Machines.

Improve energy consumption, reduce noise, optimize flow and enhance speed control with a Servo package. 

To complement our award winning ServoGear system for our DESMA 968 and 969 press series DESMA is now offering an energy saving Servo package option in their Alpha and Sigma injection machine model presses. DESMA uses system matched pumps, drives and controllers sourced from Bosch Rexroth are mated to the DRC 1030 control system.

By incorporating a Servo electric drive into the hydraulics system, improvements in our Alpha and Sigma series machines can be seen across the board in areas relating to noise reduction, optimized flow and speed control for press movements, and of course energy consumption. With a Servo option, DESMA uses just one high capacity axial piston pump. This pump can work at two different settings & output configurations depending on the flow requirement during individual press movements throughout the molding cycle. For example, during high flow requirement when pressure and force requirement is low (like for an ejector movement), the pump operates in the high flow range. Transposed, when pressure requirement for the injection machine is high (like for clamping force & injection process holding pressure), the pump works at low delivery capacity for fluid. So, for each movement, the hydraulics can be tailored to the specific hydraulic function taking place at any given time. The ability to control the hydraulics in this manner leads to additional power savings.

The defined amount of energy savings the Servo option will generate is variable depending on many factors relating to press operation & the customers determined molding process. These variables include the required cure time for the parts in addition to the number and length of machine hydraulic movements required within each cycle. It is estimated that with optimal conditions, this Servo option can save up to 36% of overall injection machine power consumption when compared to a standard proportional hydraulics system.

DESMA SmartFlow for optimal mold design

Proprietary DESMA software enhances mold designs

SmartFlow software and analysis is unique to DESMA due to material characterization and injection unit data incorporated in mold flow calculations.

Traditional mold designs try to keep cavity numbers even, runners symmetrical and equal in length to give molds the best shot at optimal balance from the start. However, there are certain instances in which our design team will be tasked with designing a mold with an odd number of cavities, or an odd number of decks, and sometimes the article itself has an odd shape that doesn’t lend itself very well to packing out completely with elastomer during part injection. Balancing an odd number of cavities is always a challenge.

In these instances DESMA utilizes our SmartFlow software in order to prove out the mold design concept and catch any issues that the flow analysis model data may illustrate. SmartFlow calculations may prove the design concept immediately. The data from SmartFlow could also indicate the need to increase the size of the runners or the gate depth, decrease the amount of runners, or which locations to add vents to prevent air entrapment during article injection. DESMA uses SmartFlow analysis data to lead the way to optimize the mold design during the CAD phase. Catching issues in the CAD phase is always the most cost effective method before cutting anything into steel. Optimizing the mold by using this data leads our customers to a more broad process engineering envelope throughout the life of the mold.

The SmartFlow analysis process starts with our design engineers creating a complete 3D mold in Siemens NX software. Additionally, our designers will create a complete elastomer model that includes everything from point of injection through sprue, runners, gates and ultimately completely filled articles and overflow grooves. We then export this NX 3D model to a raw CAD data file to be imported into our mold flow analysis software. The SmartFlow engineer will then assign a material to the elastomer from our material library. Additionally, we can even send customers supplied material for chemical analysis to assign the exact formula the customer is running to the elastomer model. Our SmartFlow engineer will then set a running temperature gradient to the mold, set the software and run hundreds of injection simulation cycles. Using this data engineers then fine tune the design and run the simulation cycles again until satisfactory results are achieved.

Do you have a mold design that you think may be a good candidate for DESMA SmartFlow and analysis?  Contact DESMA and see how we can help! namc.us@remove-this.desma.biz

DESMA FIFO-A | Flexibility for Strip Fed Material

October, 2020 (Hebron, KY) Flexibility for strip fed material plus silicone applications.

Klockner DESMA Elastomertechnic builds a variety of First-In First-Out injection units to suit different material and process requirements within the elastomer molding industry. These different types include FIFO-A, FIFO-B, FIFO-C, and FIFO-K, each of which are designed for a specific purpose.

Of the options available from DESMA, the “FIFO-A” injection unit is our most popular and most flexible.

The “FIFO-A” injection unit is designed specifically for use with vertical clamping machines in a variety of injection volumes ranging from 85 ccm up to 22,900 ccm.

One very attractive characteristic of the FIFO-A concept is the ability for the end user to change between different material types. 

The most common use of this injection unit is for processing strip type raw materials such as NBR/SBR, HNBR, FKM, Neoprene, AEM and others. However it is also quite easy to include the ability of processing HCR silicone materials by including a silicone stuffer. The addition of a stuffer to the FIFO-A injection unit can be done so that switching the machine between HCR operation and strip material operation is simple; requiring only hand tools and no more than 30 minutes.  

Connecting the silicone stuffer requires only the removal of the strip guiding device and installation of a connection pipe between the stuffer output and screw input.

Surprisingly, the same FIFO-A injection unit that is used for highly viscous materials such as HNBR can also effectively be deployed in applications to inject liquid silicone (LSR). While the conversion from strip material to LSR is more involved than connecting a silicone stuffer, the process remains straightforward. The conversion requires the exchange of the screw cylinder, injection plunger, and the addition of a LSR meter / mix system including a 2-pass static mixer.

The ability to process a wide variety of materials with the same basic injection unit provides our customers the ability to pursue business in a wide variety of markets and applications.

By combining the capabilities of the FIFO-A injection unit together and selecting the optimal process type (hot or cold runner direct injection, hot or cold pot injection transfer, or injection compression) nearly all elastomer molding challenges can be met.
