We experiment continuously with new chemicals that change the properties of our polyesters. We carefully check to make sure that the compound actually improves the characteristics of the string. We do basic testing. Mix in several ways, manufacture it, then do elongation tests and measure tensile strength, to make sure the numbers match in the lab. Then we get it out and play with it, does it feel good? That’s the most important thing, does it hold tension well, does it perform well? We test with different type high level players, youth and older, male and female, different courts, balls, weather conditions and seasons, indoor and outdoor, serve, return, forehand, backhand, measure top- and backspin rotation... we deliver the best design
Thermal stability is of major importance in polymer extrusion, where product quality is dependent upon the level of melt homogeneity. This is done by conveying the material along a heated barrel with a highly controlled rotating screw. When extruding the polyester, there are several different stages of heating up and cooling down again: Longer/shorter, faster/slower, in water or in the open air and by adding particular treatments and special coatings along the production line. A string designed with the exact same properties, manufactured in a small different way, can produce a totally different string. We try to think of new and innovative ways to change the magic formula. The best compromise out of many variables. That’s our challenge.
It is critical to ensure that the flow exiting the extruder is well controlled and constant with variations on the screw's rotational speed within strict limits. Otherwise this typically results in undesired pulsating flow that can cause periodic changes in string thickness or in micro bubbles where the probability of breaking during play is highest. These weak points in a string must be avoided at all time. To produce long length of strings having exactly same properties from begin to end, requires a lot of specific know how in the field of tennis strings manufacturing. It is an intensive learning process and needs for each run optimisation to maintain melt stability, necessary in order to always maintain good guaranteed best quality products
A tennis string is part of a system with lots of different variables influencing the dynamical behaviour. This is: The polymers combination, manufacturing process, coating,.. and also the tennis racquet design. This means strings need to be developed for all racquets, by studying and minimizing the differences. Finally an important difference is given by the stringer. We are able to measure differences between subsequent the same racquets strung by the same person. Although everybody delivers their best work, it is hard to deliver exactly the same end result each time. We strive to be the best in minimizing differences throughout the complete production chain process. We guarantee top performance consistently!
The manufacturing process is composed of two parts: The manufacturing of the string and the restringing process. We are one of the view companies engineering the complete restringing process. We measure each stroke, each individual ball contact. We talk with you, analyse the data and adapt the manufacturing process to match your needs. This can be from the polymer raw material to the final knot on your racquet. This improvement process never stops. We learn together every day. What counts is the quality of the end result: To win each time with minimum loss of your energy and with fast recovery for the next match!
Every small adaptation needs to be tested in all conditions before becoming an improvement. This can be a bit easier, for example when a string has been developed specifically for a player at one tournament recurring every year. But when developing a generic string, a string has to be tested everywhere by all type of players, in the 4 seasons and at different temperatures and weather conditions. During play a string transforms continuously. About 10%-20% of the kinetic energy is lost and is transformed in heat at each ball contact. The racquet warms up. The behaviour is different after a serve or heavy rally, compared to when starting a new game after a change over. We communicate continuously with our players, we improve together!

Our customers require technical or engineering capabilities from us to guide them to higher rankings and to maintain these higher rankings while competition is getting stronger. This means we need continuously to increase our know how not only on strings, but on the total game performance. A tennis string cannot any more be seen as a stand alone item, but has become an integral part of the total game dynamics. We need to incorporate in our future product development, the know how on dynamics of racquet, balls, court, dynamic temperature variations, pressure and humidity. Not only, but also human interaction, like sound and feel.
Our customers need predictability, systems engineering is our input. We assist in managing the technical improvement process as a team member, we win together. We offer material and manufacturing know how, we measure the quality of the racquets, we offer guidance to the stringers. We specialise in measuring and collecting data during play. We translate the data for the team to improvement points. We make things better understandable, better manageable. We study the opponent and advise accordingly for the best game plan. At the end our mission is to guarantee the most predictable ball contact possible, with highest energy efficiency transfer and constant in the longest time frame possible.
Our strategy is to focus on the performance of the product. Trying to develop new products that people can experience, try out to feel whether it’s better than what they’re currently using. As a small company, we don’t have a Nadal or Federer promoting our products, the products have to sell themselves. So instead of spending money advertising or paying players to use our products, we put all our resources into research and development and in working as a team together with top players.
