A CNC router enables Foam Fabricators to produce the typical order of 20 sample models in two days when compared to the five days necessary to cut the foam pieces by hand. As well as time savings, the CNC router liberates up engineers who previously had to pitch in and assist cut foam items each time a big quantity of examples were needed. Excluding a single person who lots the foam stock and gets rid of finished pieces, the router can run unattended night and day if necessary to transform out a sizable order. An additional benefit of automating the test creation procedure is it enables the company to consider jobs it would have lost in the past. “When the shape of the customer’s component was too complicated to cut by hand, we needed to transform out the work,” says Nathan Musgrove, an applications engineer at Foam Fabricators’ Jefferson, Georgia regional design and test center. “That hasn’t happened since we set up the CNC machine. It can accurately cut even probably the most complex three dimensional shapes.”

Foam Fabricators, headquartered in Scottsdale, State of arizona, is a coast-to-coast network of 14 services offering shape shaped foam items, packaging, and elements. Its foam goods are found in the packaging of products like electronic devices gear and home appliances, nevertheless they can even be found in other programs including within bicycle helmets. The company, that has 250 workers, molds a full range of materials such as broadened polystyrene (EPS), broadened polyethylene (EPE), expanded polypropylene (EPP), and copolymers like GECET, ARCEL, and RMER. These raw materials are injected as beads into molds, then heated up with vapor which causes those to broaden and firm up in to the finished shape. Foam Fabricators also fabricates versatile components like polyethylenes, polyurethanes, polypropylenes, and EPS, both molded and extruded.

Samples for testing

Each of the company’s local design and check facilities is staffed with degreed packaging experts and fully built with the latest in fabricating, drop screening, computerized information purchase, and CAD systems. Whenever a consumer comes to Foam Fabricators with a new item that should be packaged, the first step is to work with one of the company’s designers to ascertain the suitable material. As soon as it has been chosen, the engineer uses the customer’s specifications and CAD geometry to build up a tough design of the foam part. The Foam Fabricators engineer specifies the fabric, dimension, and gratification characteristics for that product and utilizes the SolidWorks CAD system to produce a 3D model of the first idea. At this point, most clients request between 20 and 30 samples for decrease screening. Some clients have this screening performed by Foam Fabricators while some choose to accept the examples and perform the screening in-home. There was clearly an additional disadvantage to producing examples by hand. Some of the shapes that customers required had been not possible to produce this way. For example, a jet ski producer asked Foam Fabricators to produce a bow flotation unit, a piece of foam that matches inside the bow of a four-man jet ski to provide buoyancy. “This part had plenty of complicated geometry and it was impossible to shape it by hand,” states Musgrove. “We weren’t capable of making the test, so that we had been not able to consider the task.” A third disadvantage was that this handmade models had been not extremely precise since the process of cutting them required some interpolation between areas. It was acceptable for some customers, but others wanted greater accuracy.

Among Foam Fabricators’ larger customers, who typically demands a large number of samples because of its substantial screening program, requested the company to take into consideration utilizing a CNC machine to cut the foam examples. As the company investigated this, they identified two choices: weighty and dear machining centers mainly designed for metalworking, and cheap routers that may not provide the accuracy Foam Fabricators required. Chances are they found the Techno Design 160 Production CNC router from Techno Isel, New Hyde Park, Ny, which offered the perfect compromise. The router was really accurate and sturdy which was intended for production routing and drilling on a wide variety of materials such as timber, plastic, MDF, solid surfacing materials, and nonferrous precious metals. The cost and the capabilities contained in the Techno CNC system seemed great for Foam Fabricators’ requirements, therefore the company decided to buy it. The technical specs in the Techno router they selected add a operating area for your router of 59″ x 50″ and Z-axis height of 12″, a vacuum hold-down desk, 5 horsepower Columbo spindle along with a raised gantry for large part clearance. The desk comes with a rapid travel velocity of 800 in . each minute, a Z-axis reducing force of 200 pounds optimum, .0005-” resolution and repeatability, and .003 inches/foot total accuracy.

Automated sample production

Now, whenever a customer involves Foam Fabricators having a request for a new item, the professional creates the SolidWorks model, because he performed previously. But rather than creating a sketching, he exports the strong model straight into the Techno router system’s CAM system. Initially intended for metalworking, this CAM program is also well-suited for foam due to its ability to produce by far the most complicated shape with little programming effort. Within the Camera system, the professional affords the command and also the software creates the toolpaths for cutting the test. The sole additional enter required is details like feed rates and cutting rates of speed. Total programming time, from when the SolidWorks design is brought in to the CAM system up until the system is able to reduce foam, ranges from half an hour to 2 hrs based on the intricacy of the component.

After a piece of foam carry is fastened towards the Techno router, the owner hits the “begin” button and also the sample will then be etched instantly. The machine fails to need any guidance, other than to eliminate the finished item and attach a whole new foam obstruct to repeat the process. With this machine, a typical order for 20 examples is done in 2 times. Big test purchases no longer need the creation assistance of designers. The machine is just kept provided with stock and run up until the order is finished.

Foam Fabricators has become very pleased with the longevity of the Techno router. With just normal lubrication, it functions perfectly. Part of its dependability is because of the types of materials used in its building. For instance, the machine utilizes anti-backlash ball screws. These screws have outstanding energy transmitting as a result of moving ball get in touch with involving the nut and screws, and this kind of get in touch with ensures reduced rubbing, low put on, and long lifestyle. The ball anchoring screws also have the ability to produce parts to the machine quality of .0005 inch. Furthermore, the machine constructed on metal stress alleviated bases with hardened metal linear ways, and ballscrews with servomotors regular, that offer the best accuracy performance, speed capacity, and machine longevity. This shaft-and-having system generates really smooth, play-free movement and is certainly a rigid system that creates high-quality slashes.

Customers appreciate the faster turnaround on examples. Those who need to have a high amount of precision inside their samples are observing an improvement from your Techno router here, as well. Most importantly, clients who visit Foam Fabricators seeking packaging components will have confidence the company can undertake their work, regardless how complicated the shape with their components. Because the CNC yvctke imports CAD geometry and replicates that shape exactly, regardless of the complexity, Foam Fabricators is no longer confined to simpler shapes.

Obtaining the CNC router has paid off for Foam Fabricators inside a number of methods: quicker turnaround on examples, more accurate samples, much better pleased customers, and the cabability to handle more advanced jobs. Additionally, having a CNC router assists the company compete against other shot foam molders. “Making samples on a CNC machine it becoming the standard in our industry,” clarifies Musgrove. “Using the Techno machine, we found an expense-effective way to fulfill this requirement.”
