Progress in titanium investment casting

Written by depehz on July 20, 2022. Posted in 2022. No Comments on Progress in titanium investment casting

Progress in titanium investment casting a speech by Florian Bulling Introduction Titanium alloys are known for their high mechanical strength, low density and high corrosion resistance. Therefore, their application is mainly in the field of aerospace industry, but also in medicine as implant material. The alloy Ti-6Al-4V, also known as Grade 5 titanium is the most widely used alloy. Other titanium-based alloys are the intermetallic compounds NiTi, known as Nitinol®, which is used for its superplasticity as stent material or as actuator. Another important alloy is the intermetallic...

The importance of grain size in jewelry alloys and its control a speech by Chris Corti Abstract Control of grain (crystal) size in jewellery manufacture is important for several reasons. It affects the properties of the alloys – mechanical, chemical and physical. These, in turn, influence the manufacturing process and the jewellery’s behaviour during wear by the customer.There are a number of ways grain size (and shape) can be controlled in precious metal jewellery alloys – by casting, working and annealing and by use of alloying additives that refine the grain size during casting and...

Jewels from 2020 – Designing innovation

Written by depehz on January 27, 2020. Posted in 2020. No Comments on Jewels from 2020 – Designing innovation

Jewels from 2020 – Designing innovation a speech by Beatriz Biagi Jewellery trends evolve slowly. While other industrial sectors develop and adopt technological innovations quickly, the fine jewellery sector around the globe largely sticks to “same old” production and commercial procedures, feeling no urge to change. Cultural and security issues play a major role in both, keeping fine jewellery a priority for established customers and failing to address a growing number of potential customers. Over the past 3 decades customer attitudes towards precious jewellery have not changed...

The finishing of accessories: a must in the fashion industry a speech by Giulio Bevilacqua Fashion and the electroplating business. Two apparently distant worlds linked by a technical dialogue that aims at getting things done: fashion brands on the one hand, and finishing “suppliers” on the other. The challenge: to build a business meeting point between strategic sectors that are tendentially little inclined to cross-contaminate and communicate in order to create a new way of thinking about luxury finishings. A dialogue which inquisitive observation, together with 50 years’ experience, has...

Simulating the casting process for jewelry

Written by depehz on January 27, 2020. Posted in 2020. No Comments on Simulating the casting process for jewelry

Simulating the casting process for jewelry a speech by Vera Benincasa Simulating processes has been mandatory in many companies from the most diverse manufacturing sectors for years. One only need think of the aviation industry where companies must be absolutely certain that the components produced have no micro-structural defects whatsoever and where a rejected part cannot be re-processed. Casting process simulation identifies areas subject to defects and helps to design the casting system in the most efficient manner. It also allows the causes of any inefficiency to be analysed and to...

Lab-grown diamond: is it a commercial problem for the future?

Written by depehz on January 27, 2020. Posted in 2020. No Comments on Lab-grown diamond: is it a commercial problem for the future?

Lab-grown diamond: is it a commercial problem for the future? a speech by Antonello Donini We are talking about SYNTHETIC DIAMOND Crystalized carbon (C) in the cubic system and arranged tetrahedrally within the grid. As with natural diamond, this configuration gives the material properties that make it unique. Therefore, we are not speaking of an imitation but of an authentic diamond produced by artificial synthesis methods made by man rather than by nature. Initial attempts to produce the exact synthetic counterpart of diamond in the laboratory date back to the late 19th century,...
