How to Find a Injection Moulding in Alto ?
Whether the fabricator’s shop is large or small, the Ironworker is the backbone. The Ironworker isn’t a single machine; it is five machines united into an engineering wonder. It has much more versatility than most people would imagine. The five working sections that are involved in the make-up of this machine are a punch, a section shear, a bar shear, a plate shear, and a coper-notcher.
A number of the cheaper ironworkers are constructed to employ a fulcrum where the ram shakes back and forth, building the punch go into the die at a small angle. This normally leads to the eroding of the punch and die on the front rims. The higher quality machines integrate a ram which moves in a direct vertical line and employs modifiable gibs and guides to guarantee a constant traveling route.
When you look for a End of Arm Tooling (EOAT) that develop a Injection Moulding in Alto, looks for experience and not only pricing.
That gives more life to the tooling, and allows the punch to penetrate the die right in the middle in order to capitalize on the machine’s total tonnage.
When looking for a design house that designs a Injection Moulding in Alto don’t look just in Michigan , other States also have great providers.

This job is among one of my favorites. It’s because the entire project was mine. I started by going out to their facility and seeing their inefficiencies. One cell that they were very excited to revamp was their Silica dump cell. I was able to come up with the initial concept, quote the project for materials and labor, and then do the engineering myself. I did, not only the mechanical design and detailing, but also the electrical and pneumatic schematics. I felt in charge of the whole thing- high risk, but high reward.
A HUGE 6 axis robot (ok, not that huge, I’ve used bigger) but an R2000 robot picks up these paper bags filled with Silica. The end-of-arm-tooling (EOAT) used vacuum suction to hold onto the bag.Solidworks Rendering of EOAT
It bring it over to a hopper, where a smaller robot uses a knife to cut the bags. The larger robot then flips it’s tooling to dump the Silica into a hopper. Seems pretty simple and for the most part it was. However, the Silica is so densely packed into the bags that even when the bags were cut wide open, the Silica wouldn’t dump. To help the Silica loosen and fall, we stick needles into the bag and blow air through these probes which moves the Silica powder around. We then (for a lack of engineering terms) flap the bag to further empty the Silica. It may sound tedious, but any powder or residue left in the bag is money wasted for the company.
An SMC slide cylinder pushed the air probes through the paper bag, and the fittings attached to the other side provided air to go through to the holes in the probe.
Another part of the project was to add a tool changer to the smaller robot. It was originally just equipped with the knife, but by adding a tool changer with a “Silica break tool” the robot was able to then go into the hopper and break up large clumps of Silica helping the contents of the hopper drain. Imagine a giant potato smasher. (Which is in fact what we ended up often calling the tool.)Potato Smasher Robot
I had a lot of fun working with my machinist and builder on this project. I did everything I could to help them succeed, but also knew they had my back on this as well. I understand that that dynamic not all that common in the work place, so I really appreciated it. The install is happening currently and now the programmer is up to bat. The EOAT has a camera and laser to locate the bag. The camera locates the XY location of the bag and the laser the Z (height) location. I can’t wait for the tooling to be fully power, programmed, and running. I really think the customer will be happy with this addition.
Obviously enough, one of the first things many people want to know when getting started with scrolling as a hobby is what saw to buy. Whether you are looking to purchase your first scroll saw, or you are looking to upgrade to a better one, there are many things to consider. In this article I will attempt to touch on all aspects so that you are able to make an informed decision. I will also make some recommendations based on personal experience and what I feel is the general consensus of the scroll sawyers I have discussed the matter with.
Blade Changing and Blade Holders: The saw should accept standard 5" pinless blades. A lot of scrollwork simply cannot be done with a saw that requires pinned blades. While pinned blades have some advantages, they have one very big disadvantage: You can't cut any small inside detail cuts since you have to drill a very big hole to get the blade's pin through.
Also, how easy is it to change a blade? Is a tool required for this? Some scroll saw projects have hundreds of holes. This means you have to remove one end of the blade from the holder and thread it through the wood and re-mount it in the holder more times than you can count. Be sure the process is comfortable and relatively easy to do. A saw in which the arm can be raised and which holds itself in this position is most desirable as it makes this process much easier as do tool-less blade holders.
Variable speed: A great many saws offer variable speed and you should not have a problem finding this feature in any price range. Sometimes you will want to slow the blade down just to cut slower, other times you must slow it down to prevent the blade from burning the edges of the wood as you cut. Some scroll saws require belt changing to change speeds. Personally, I would highly recommend a saw an electronic speed control.
Vibration: Vibration is very distracting when cutting and must be kept to a bare minimum. Some saws inherently vibrate more by design. This feature tends to be very much dependent on the cost of the particular saw. Vibration can be reduced by mounting the saw to a stand. A sturdily mounted saw and heavier saw/stand combination will reduce vibration. Many companies offer stands purpose built for their saws.
Size Specifications: Manufacturers often list the maximum cutting thickness of their saws. Since this is always more than 2", you can ignore this as you likely will never want to cut anything thicker than that on a scroll saw.
The depth of the throat however is something you may want to consider if you think you will be cutting very large projects. A small throat will limit how big of a piece you can swing around on the table while you cut. For many this is not a very big deal since it is somewhat difficult and unpleasant to swing around a big piece of wood on a scroll saw. This limit can also be circumvented by the use of spiral blades which don't require the work to be rotated at all.
A most notable difference between the Excalibur and other saws is that the head of the saw tilts rather than the table. This is a nice advantage if you intend to do a lot of angled cutting. The one feature that I personally am leery about is that you only have a quick release for the tension at the front of the saw's upper arm and the fine adjustment is at the back of the arm. This is a relatively recent change to the saw however I have not seen any negative feedback about this setup. Theoretically, once you have set the fine adjustment, you don't have to adjust it very often and you just need the quick release when undoing/redoing the blade to feed it through your project.
These saws are manufactured by General International, which has a reputation for quality.
Other notable mentions RBI and Eclipse both offer high end saws with great performance and low vibration. You may want to check these saws out if you can afford them. Since they are out of most people's price range, I have not heard a whole lot of feedback on them. In my opinion, many of these models do however have inconveniently located controls and/or require tools for blade changes which do give me cause for concern.
Hegner offers four different models starting at about $700 and going all the way to $2400. The lowest end model "Multimax 14-E" is only single speed which I would definitely stay away from. In my opinion there are several better choices for a comparable or cheaper price. The $2400 industrial "Polymax" model requires belt changing to change the speed which is an inconvenience. Because of this issue and the high price tag, I would only consider this model for a truly industrial purpose. This leaves us with the Mutimax 18-V and 22-V models to consider.
All Hegner saws require tools for blade changes. This fact, in addition to what I would personally consider an inconvenient control layout would make me think twice about a Hegner. That being said, most people who own Hegners are very happy with the quality and usability of their saws. Since I have not personally used one, I will leave this matter for your further consideration if you can afford a saw in this price range.
I hope this article has provided you with enough information to allow you to make the best possible investment of your money so that you can start with or upgrade to a scroll saw that will provide you years of scrolling pleasure.
