Luxury Goods

Brilliant appearance down to the last detail

“Shine bright like a diamond…” Luxury goods live on aesthetics, precision, and quality. Everything must work together perfectly. Pureon’s customer solutions shine – even when hidden.
Who does not know someone in their family or circle of acquaintances who has an arti􀉾icial hip joint? When the largest ball-and-socket joint in our body goes on strike, arti􀉾icial replacement is a blessing for patients. Today, this surgical procedure is considered routine. In view of demographic change, the market for implants that give older people back their lost mobility is growing. In the process, the technology of surgical mechanics and machine tool builders is becoming ever more sophisticated. What is the key here
A hip joint works like a sliding bearing: the parts that move relative to each other have direct contact. And this is exactly the point where it can become painful due to wear and tear. New prostheses are modeled as closely as possible on the natural joint and are made of metal alloys, ceramics, and special plastics. The artificial joint consists of a stem that is anchored in the thigh bone, the femoral head, the hemispherical cup that is inserted into the natural acetabulum, and a cup insert, also called an inlay. For the patient to be able to walk and play sports again soon after surgery, the ball and socket must fit together without friction. This sounds simple, but it is not.

It is no coincidence that endoprosthetics, like all applications on humans, is subject to strict regulatory requirements. In addition, bacteria and contaminants in artificial joints are dangerous enemies of successful treatment. Biocompatibility is therefore a must. The be-all and end-all in the manufacture of hip prostheses is the polished surfaces of the ball, cup and cup insert with the fineness required by

The company delivers “customized” in close exchange with the customer. Be it the manufacturer of the joints themselves or the machines that produce the components for them. Polycrystalline diamond, which Pureon produces itself in the USA, has proven ideal for polishing the joint components. The combination of a rough particle surface, optimal grain shape and an application-specific suspension formulation makes the difference in quality and gives our customers higher productivity,” explains Martin Spring, co-CEO of Pureon. This is because the Pureon team optimally matches the properties of the carrier fluid, such as temperature or viscosity, to the polishing process in question. The specific formulations are applied to the joint, sprayed or brushed, and then polished to remove minute damage to the surface step by step as the grain size of the polishing agent becomes finer and finer.

At Pureon, the specialists leave nothing to chance. The internationally positioned medium-sized company has a quality management system according to ISO 9001 and can control – and trace – every step in the value chain from in-house production of the diamonds to delivery.

manufacturers and surgeons. And, of course, the patient relies on his prosthesis functioning fflawlessly for decades. Pureon’s high quality standards can guarantee this.
This is the software-controlled classification of grain sizes by sedimentation, a complex wet process. This is the only way to guarantee unsurpassed surfaces of consistently high quality. This makes the difference. The professionals in watchmaking have a trained eye and not infrequently refrain from defining specifications in detail. Because they recognize the quality of a surface at first glance!

Pureon delivers the desired quality – and the success proves the diamond experts right: more than 50 percent of all Swiss watch brands use components that have been polished with products from the micronizer in Lengwil, Switzerland. Pureon can boast the largest range of suspensions on the market, with sales of 100,000 liters per year. You can always find a solution there. This is true in haute horlogerie, where small quantities and high margins are often required, as well as for less exclusive pieces. In addition, Pureon is setting itself up for finishing in the mass market. Apart from manufacturers of very inexpensive watches, this component is at the top of the agenda for all customers: watch glass made of sapphire.
The synthetically produced crystal makes the glass scratch-resistant, heat and pressure resistant, and provides good optical transmittance. But the hard sapphire can only be dealt with diamond. Polycrystalline diamond suspensions are unbeatable in this respect, a real hit, if you will. Pureon is the world leader in this field. Diamond suspensions are available in ready-to-use formulations. This saves time and money. The results: first-class, reproducible surfaces with short processing times.

Keyword speed. For manufacturers of gemstones, the question of how many specimens can be cut per second is business-critical. Because in this large market, the cost pressure is particularly high. We are talking here about synthetic gemstones made of zircon, spinel, marcasite, ruby or moissanite. They are grown, the stones cut and then mounted, to be faceted and polished with diamond grinding wheels or suspensions. Such a stone can have up to 57 facets, what counts is the brilliance of the imitation diamonds.

Here, too, it is important to choose the right suspension or liquid concentrate, guaranteed free of agglomerates. This is the only way to achieve perfect polishing results right away and drastically reduce the reject rate. It takes a lot of know-how to perfectly combine the numerous additives of the suspensions. And decades of experience – as Pureon has to offer
