Water jet cut design for a scientific glass beaker stir breaker device design overview...
Design Over view:
We can use the water jet cutting process to offer an improved, more simple and cost effective way of completing a project.
This is a design for a device to be inserted into glass beakers for experimental purposes. The concept is to break up the swirling motion when the contents are stirred in the laboratory by a magnetic stirring machine. We were approached by the scientific glass beaker manufactures with an idea of how this could be made using stainless steel tubes that were then machined and bent. However, we devised a better solution to the problem, which has been a great success.
customer design solution to a scientific glass beaker stir breaker device...
Customer design solution:
Our customer supplied a full sized paper model of what they had in mind and stainless steel tubes to be machined and bent to create the parts, these can be seen in the picture.. We pointed out various issues and costs involved in manufacturing the product in this way and offered an alternative solution.
A big problem with their original plans is that the cost to produce the tooling was out of budget, and it needed to be flexible to offer different sizes of the finished product.
So we looked at ways to produce the finish product more cost effectively and by using our 3d cad design service and our water jet cutting service we were able to come up with the perfect result.
Scientific glass beaker stir breaker device finished parts...
Manufactured from stainless steel, the finished parts are shown here in two sizes, the outside diameters and heights would always change. We designed the product in 3d cad and then water jet cut all the 2d parts. There were 6 parts per assembly, tig welded at the joins.
With the water jet cutting process giving us burr free parts, no heat affected zone and clean cutting, very little finishing was required and the parts were clean so no weld preparation was necessary to tig weld the joins.
This picture shows three finished parts in two different size variations.
Water jet cut design for a scientific glass beaker stir breaker device installed into glass beakers...
The finished Scientific glass beaker stir breaking device installed in some glass tubes:
This image shows our design installed into some glass tubes. Using the special design feature of small legs which grip the glass with a sprung tension enabling them to be positioned in the beakers at varying heights.
The concept behind these is that they can be set at the right height by using the small gripping arms to grip the inside of the tube, then the paddle design on the four uprights interferes with the solution that is being stirred / mixed in the beaker by the magnetic stirrer, this creates a break in the swirling motion of the fluid, resulting in a better mixing process / vortex interrupter in the laboratory.

Safire Design solution:
This is a 3d cad render drawing of the assembly we came up with to solve their problem and produce the stir breaking device, made up from 6 parts all water jet cut from stainless steel sheet.
All the parts clipped together and were held in a jig so we could tig weld them at the joins.
By designing this in 3d cad we were able to make sure everything worked as intended, we could work out all the part geometries and then produce all the workshop data to produce the finished parts in our work shops.
