The document discusses the lost foam casting process which involves:
1) Expanding polystyrene foam beads that are filled into an aluminum tooling cavity.
2) Heating the foam to expand and fuse it into the shape of the cavity.
3) Cooling and removing the foam pattern, leaving a mold to be filled with molten metal.
4) Pouring molten metal which replaces the foam that is liquified and volatized, resulting in a metal casting that accurately reproduces all details of the original part design.
Description of the Lost Foam Casting process and explanation of what makes the Lost Foam Casting Process preferable to other forms of casting techniques.
Shown for the first time at the VII Moscow International Lubricant Week, Molykote® experts present a new range of lubricants developed through the use of unique patented technology.
New silicone copolymer lubricants combine the thermal stability of phenyl siloxanes with the wear resistance of fluoro siloxanes to deliver increased wear resistance even at high temperatures. The balance of phenyl and fluoro groups can be adjusted to produce the ideal solution for each tribological challenge.
With high-temperature lubricity achieved, without sacrificing low-temperature operation, these new oils and greases function effectively in a wide range of temperatures (-35°C to 220°C) – delivering superior performance against ester based lubricants. With a lower density than PFPE lubricants, they offer lower cost-per-use and their wide additive acceptance delivers additional properties such as corrosion and oxidation resistance.
See the results of the research and development along with a direct comparison against a range of silicone, PFPE and ester based lubricants.
A wide range of applications are emerging as we work with industry to launch further ranges within this group. Contact your Molykote representative now to request a development sample.

Removing gaskets from the flange connection can be
a tedious and labour intensive task which can result
in flange surface or equipment damage. When using
hammer and chisel to remove a gasket from the flange
surface, one can damage the latter. The amount of time
spent on cleaning flanges can be significant, and in
many cases, the plant must remain off-line while the
gaskets are being removed, creating a loss of valuable
production time. It has an important impact on maintenance
costs and plant efficiency. To avoid these problems
using gasket materials with a proper anti-stick
coating is recommended.

Stress Ratio Effects in Fatigue of Lost Foam Aluminum Alloy 356 Dave Palmer, P.E.
Lost foam casting is a highly versatile metalcasting process that offers significant benefits in terms of design flexibility, energy consumption, and environmental impact. In the present work, the fatigue behavior of lost foam cast aluminum alloy 356, in conditions T6 and T7, was investigated, under both zero and non-zero mean stress conditions, with either as-cast or machined surface finish. Scanning electron microscopy was used to identify and measure the defect from which fatigue fracture initiated. Based on the results, the applicability of nine different fatigue mean stress equations was compared. The widely-used Goodman equation was found to be highly non-conservative, while the Stulen, Topper-Sandor, and Walker equations performed reasonably well. Each of these three equations includes a material-dependent term for stress ratio sensitivity. The stress ratio sensitivity was found to be affected by heat treatment, with the T6 condition having greater sensitivity than the T7 condition. The surface condition (as-cast vs. machined) did not significantly affect the stress ratio sensitivity. The fatigue life of as-cast specimens was found to be approximately 60 – 70% lower than that of machined specimens at the same equivalent stress. This reduction could not be attributed to defect size alone, and may be due to the greater frequency of oxide films near the as-cast surface. Directions for future work, including improved testing methods and some possible methods of improving the properties of lost foam castings, are discussed.

What is cast iron, its process, properties and applicationsSearchnscore
Cast Iron is a ferrous alloy consisting of 2 to 4.5 % of Carbon, 0.5 to 3 % Silicon and small amount of Sulphur, Manganese and Phosphorous. It is generally cast as soft and strong or as hard and brittle iron. Usually made from Pig Iron, cast iron is formed by liquefying it, followed by pouring it in a mould and allowing it to cool.
The expandable STMMA co-polymer is very popular in Chinese lost foam casting foundries. Here I posted the detailed specification of STMMA for studying by my friends.
The advantages of co-polymer used for lost foam casting:
Reduces carbon defects in castings
Reduces carurization defects on the surface of steel castings
Reduces smoke carbon
Improves surface finish of castings
Reduces the total production costs

Neuro-symbolic is not enough, we need neuro-*semantic*Frank van Harmelen
Neuro-symbolic (NeSy) AI is on the rise. However, simply machine learning on just any symbolic structure is not sufficient to really harvest the gains of NeSy. These will only be gained when the symbolic structures have an actual semantics. I give an operational definition of semantics as “predictable inference”.
All of this illustrated with link prediction over knowledge graphs, but the argument is general.

Epistemic Interaction - tuning interfaces to provide information for AI supportAlan Dix
Paper presented at SYNERGY workshop at AVI 2024, Genoa, Italy. 3rd June 2024
https://alandix.com/academic/papers/synergy2024-epistemic/
As machine learning integrates deeper into human-computer interactions, the concept of epistemic interaction emerges, aiming to refine these interactions to enhance system adaptability. This approach encourages minor, intentional adjustments in user behaviour to enrich the data available for system learning. This paper introduces epistemic interaction within the context of human-system communication, illustrating how deliberate interaction design can improve system understanding and adaptation. Through concrete examples, we demonstrate the potential of epistemic interaction to significantly advance human-computer interaction by leveraging intuitive human communication strategies to inform system design and functionality, offering a novel pathway for enriching user-system engagements.
Kubernetes & AI - Beauty and the Beast !?! @KCD Istanbul 2024Tobias Schneck
As AI technology is pushing into IT I was wondering myself, as an “infrastructure container kubernetes guy”, how get this fancy AI technology get managed from an infrastructure operational view? Is it possible to apply our lovely cloud native principals as well? What benefit’s both technologies could bring to each other?
Let me take this questions and provide you a short journey through existing deployment models and use cases for AI software. On practical examples, we discuss what cloud/on-premise strategy we may need for applying it to our own infrastructure to get it to work from an enterprise perspective. I want to give an overview about infrastructure requirements and technologies, what could be beneficial or limiting your AI use cases in an enterprise environment. An interactive Demo will give you some insides, what approaches I got already working for real.
