Automated Tennis Ball Tester
During Wimbledon the tennis players will use over 50,000 tennis balls. These balls have to behave consistently and uniformly. To ensure this the balls used in tournament play must be approved by the International Tennis Federation (ITF).
As part of the approval process the tennis balls are put through a variety of quality control tests using an automated test system, designed by Mecmesin. This versatile test system can accommodate "standard" size tennis balls used at Wimbledon as well as the larger sized, slower foam balls which are designed for use by beginners. Testing includes compression and relaxation to check forward and return deformation, ball diameter and ball weight. By using an automated sample handling system, testing is more reproducible and can be monitored remotely, leaving technicians free to perform other tasks.

Manual Handling Kit
Musculoskeletal force measurement is an effective method of:
- Evaluating muscle endurance
- Diagnosing recovery and post-injury rehabilitation
- Predicting the training needs and fitness levels of an athlete
- Aiding the process of planning training programmes for athletes and tracking an athlete's progress during training
Mecmesin's Manual Handling Kit is the ideal solution for testing isometric muscle strength:
- Abduction and adduction
- Internal and external rotation
- Extension and flexion
- Pronation and supination
- Grip and pinch strength
The portability of the manual handling kit makes testing in the office or the sports track very easy, as it requires minimal set-up and provides credible data to enhance and maintain precision quality sport health assessments.

Mecmesin Testing Tip
|
|
Selecting the Right Tensile Testing Grip
Selecting the correct grip and grip faces is critical for testing success. Successful gripping solutions require the specimen to be held in a way that prevents slippage and jaw breaks and ensures the force is applied uniformly. When selecting tensile grips, many factors have to be given consideration including:
- The size, shape and material of the sample
- Load capacity required
- The test requirements
In many cases a general, all-purpose grip like a Wedge Grip will be the right choice. General purpose grips and fixtures have the advantage of being able to grip a wide variety of specimen types and materials using a range of options such as different jaw faces, alignment fixtures, etc.
|
|
However even though Wedge Grips are versatile the structure of a Wedge Grip is heavy and their serrated jaws may easily distort and damage or worse, break fragile materials. Therefore, it is recommended that Wedge Grips are used wherever possible for testing specimens constructed of harder materials and that require a higher load capacity. Fragile textiles may be better tested using for example, a Spring Loaded Fold Grip.
Some grips are available with jaw inserts e.g. smooth, serrated or rubber coated. Proper jaw selection is important to ensure the sample is held securely and slippage or sample breakage does not occur.
Some grips are pneumatic to ensure the grips will always close at the same pressure, as opposed to the mechanical grips where individuals may tighten the grips differently.
Mecmesin has a wide range of standard grips and fixtures but in some cases the gripping requirements are very specific and a purpose-designed grip or fixture is necessary to meet a particular testing standard. Our special applications engineering team is able to design and manufacture bespoke accessories, fixtures and fittings to your exact requirements.
