Castings without pattern – A new way to produce iron sand castings

Nopatech™ is a new technology developed by Saguenay Foundry. Its purpose is to make very short production runs of gray & ductile iron castings faster and more cost effective by eliminating the need to produce a pattern.

In regular production, patterns are made de create an imprint in a sand mould. Metals are then poured in the “negative” of the part. After cooling, you get a part to the correct dimensions and shape. This technology has been done for hundreds of years to obtain complex shapes that could not otherwise be machine directly in a cost-effective manner.

The problem with patterns is that they are expensive. If you redo the castings dozens or hundreds of even better thousands of time, it can easily be amortized. But in certain situations, one or two castings might be all you need. For instance, prototypes of an unproven design are subject to change after a trial of one or two castings. With a pattern, some change can be made, but not always, so you are always taking a risk.

In this case, a casting that cost 2000$ can require a 5000$ wood pattern do be produced effectively. If you do only one, your casting has cost you 7000$ . Nopatech™ on the other hand might cost you only an extra 1500$ – 2000$ to cast a part without pattern . This is a very substantial gain. The lead time might also go down by half.

To obtain this low cost and fast lead-time, Nopatech™ benefits from the advance in robotic technologies to machine blank sand moulds directly to the final shapes. Cores can also be done, so there is no limit to the complexity of the final shape. Basically, what can be done with wood patterns can be done with Nopatech™.

Also, the quality matches exactly what you get from a casting made with a regular pattern. You reach an average “as cast” RMS figure of 500 and the accuracy of the mould is within 1/16” of an inch, a precision that compares favourably to pattern-made parts. The size limitations is also the same as any other part done at our foundry, with a 115” x 115” maximum flask and a 16,000 lbs gross weight pouring capacity.

The process of producing a sand casting

What is a sand casting? How dose it comes out? The following passages would give you some answers.

Have you seen a large metal made of iron, bronze, brass of aluminum with some featured patterns in the middle? Have you noticed a cavity of wood or metal? If you say yes, I think you have already got the idea of casting. The sand is a cast part produced by forming a mold from a sand mixture and pouring molten liquid metal into the cavity in the mold. After the process of cooling, the melted metal has been solidified. At the last, a sand casting would be gotten just separated from the mold. Generally speaking, it is produced as follows.

The basic step is to place a pattern in sand to create a mold. It should be mentioned that the mould has two parts divided by the parting line. The cope is the upper half and the drag is the lower half. And as you know, there are 2 main types of sand. One is called the “green sand”, and the other is the “air set”. The previous one is a mixture of silica sand, and the latter one is dry sand with other material through curing adhesive.

Then, remove the pattern and pour the melted metal to the mold. You can use the vibration and mechanical method to remove the pattern. And the cope is separated from drag. Within the mechanical methods, the sand mixture is assembled to for a mold cavity. According to the different types of sand, the change happened during this process is different. Whatever, a riser is needed to hold excess molten material to avoid the holes in the main casting.

Next, allow the metal to cool. At this moment, the liquids are solidified. It is time for you to break away the mold and remove the casting. It is true that the mold is destroyed in the removal process. However, the pattern itself can be reused to produce new sand molds. And if you want a more elaborate casting, surfaces should be polished.

The producing process appears to be simple. But it is definitely not. It is certain that each one hopes to produce a casting with high accuracy. It is a work which needs enough practice. During the process of casting, it is advisable to reuse some of the components of the sand mixture lost in the thermal casting process. Whatever, the material determines a lot. Generally speaking, sand castings made from coarse green sand impart a rough texture on the surface of the casting which makes them easy to identify. However, air-set molds can produce castings with much smoother surfaces.

Safes: 3 Major Historical Developments

If you have ever seen a Robin Hood movie (animated or not), you may have noticed that when Robin robbed from the Sheriff of Nottingham, the gold was often kept in a wood box that was bound with iron straps. These were called strong boxes, and are the precursor to modern day safes. It seems rather obvious that a wood box has limited security potential, and offers almost no protection against fire, but it wasn’t until the late 1700′s that we started seeing serious efforts in what would become modern day safes. Let’s take a look at three of the these developments.

The first, and probably most obvious upgrade was in the late 1700′s. Though cast iron strong boxes may have been around on a limited basis, in the 1780′s they became more widespread as iron became less expensive. They were commonly seen in the homes of the wealthy upper class in England. The term safes was not yet in use, so at this point they were called iron chests. These chests were about 1/2″ to 1″ thick and were cast in one piece. Doors were cast also from one piece and of similar thickness to the body.

But iron chests and the old strong boxes were specifically designed against theft, not for fire protection. It wasn’t until the 1800′s that manufacturers started to make safes to protect against heat and fire. It is in the quest to protect against fire that we see the second major development in safes.

One of the first fire resistant patents was filed by Richard Scott in 1801, but there is no evidence that he used it. Others were also working on fire resistant security boxes, with the idea to have multiple layers of metal with slow conducting materials between layers.

It was Thomas Milner, a tinsmith from England who developed in the 1820′s a safe that was composed of two thin sheets of strong tin plate, with a layer of sawdust mixed with alum sandwiched between the tin. When the safe was exposed to fire, the alum melted which resulted in the sawdust being dampened. The wet sawdust stopped the conduction of heat to the inside of the safe. Though fire resistant, it was not very secure against burglary.

Over the next decade, the wood based insulating material evolved several times until in the 1840′s when Daniel Fitzgerald discovered how to use a liquid form of plaster of Paris for insulation between heavy iron plates. This was called the “Salamander Safe” (after the amphibian that in folklore is said to be able to survive a fire). The only problem that was discovered was that items inside the safe became damp. With a few small changes in the composition of the plaster, the problem was solved. This innovation is credited with a lot of success in protecting valuables during fires in the nineteenth century.

The third major development of safes came with an improvement in burglary protection during the 1840′s (around the time that the term “safe” came into use). During this decade, and from a few different sources, we saw the development of diagonal bolt systems for locks, the use of strong plate iron, and drill protection used around the locks of safes. All of these made safes harder to break into, which became big public sport among safe manufacturers of this time period.

Safes have definitely come a long way from the original wood strong box. These three major break through in its development are the building blocks to the modern safe, in which we still see innovation and improvements today.
