The difference between table tennis racket and diy racketThere were many differences between a table tennis diy racket (handmade racket) and a finished racket:
1. ** In terms of composition **
- The finished product was made of rubber and bottom plate, which were usually pressed by a machine. The diy racket was usually composed of two parts, the rubber and the bottom plate. You needed to choose the suitable bottom plate and rubber, and then stick it with an organic glue.
2. ** In terms of performance **
- In terms of elasticity, the elasticity of the finished product is small, and the elasticity of the diy pat is better. The finished product was hard, dead, and weak. The rubber was hard and weak. It was weak in the middle and far stage. The strength and speed of the near stage were not fast enough, and the backhand was not strong enough. The diy racket basically crushed the finished product in terms of elasticity, speed, friction, and so on.
- As for the rubber, the rubber of the finished product had a shorter service life. After the rubber of the diy shoot was damaged, it could be torn off and replaced, but the rubber of the finished product could not be replaced.
- From the bottom plate, many low-star wood products would be made of sawdust. The wood that was purchased separately was better, and the texture was obvious.
3. ** Production process **
- The finished pats were produced by the machine assembly line, which had a great impact on the rubber and the bottom plate. Usually, the glue was more solid, resulting in the lack of elasticity of the rubber sponge, which was hard and dead. The diy pats were pasted by themselves, which could avoid this problem.
4. ** In terms of cost-performance ratio **
- For high-star finished products, there was a certain performance, but often the same price of the performance of the diy racket was much better than the finished product, or the same performance of the diy racket was cheaper than the finished product. Low-star finished products were cheap and did not have much performance, so it was not cost-effective.
5. ** Adaptability **
- For table tennis novices, the finished racket could meet the performance requirements because the novices didn't have their own playing style, so the finished racket was more popular. However, as long as there was a certain basic level, the finished racket could not meet their own performance requirements. However, the diy racket could be selected according to their own playing style and technical level, and there were a wide range of choices.

carbon fiber racketThe carbon fiber racket was made of carbon fiber woven composite materials. In the 1970s, Japan began to use carbon fiber materials in the racket, and then the United States began to use carbon fiber composite materials for racket manufacturing, opening the first use of carbon fiber composite materials in the racket industry.
The carbon fiber racket had many advantages over the traditional material racket, such as its low density, high specific strength and specific module, higher fatigue resistance, higher design freedom, and good shock absorption. It could help athletes improve stability, reduce vibration, and make the ball more stable.
In terms of production technology, the production process required high temperature and high pressure to allow the carbon fiber and the resin to interact to form a complete racket. There were differences in production processes and materials between mass-produced rackets and rackets for professional players. The rackets for professional players cooled slowly before opening the mold, which took a long time and increased the cost. The carbon fiber and resin used were of better quality, more stable and consistent, and the price was higher.
Different types of rackets (for example, professional rackets and amateur rackets) differed in many ways:
1. ** Model **: Professional players are used to using racket models from the early stages of their career. Muscle memory makes them rarely change them. The sponsors keep the early models to produce the racket for them. For amateurs, it is more difficult to get the same racket as professional players, and the racket performance has changed in the past 20 years.
2. ** In terms of parameters and accuracy **: Professional players 'rackets have huge differences in parameters, such as length, weight, pounds, etc., which may reach higher or lower values, and there are also differences in accuracy. They will also make custom-made modifications to the racket, such as adding weight, changing the length of the handle, changing the drilling of the string bed, etc. There is a certain quality error in amateur rackets. At present, the better brands can guarantee a margin of error of 5 - 7g.
3. ** Handle **: Professional players can customize the shape of the racket handle according to their needs. The inner handle leather is mostly made of calfskin, which has the advantages of durability, stable performance, and sharp edges. However, some players use artificial inner handle leather. Amateur rackets rarely have such custom-made handles.
4. ** String **: Most professional players use catgut + pet fiber, which is more expensive. Some players use string brands such as Babolat's rpmblast. Amateurs can choose according to their own situation.
In comparison to the carbon racket, the carbon fiber racket was sturdier and more elastic. The carbon material was an unprocessed material. The carbon fiber was made from carbon fiber and then woven into a net to make the racket. After weaving, the carbon fiber was more flexible. Nowadays, the mainstream racket was made of carbon fiber. Blockade rackets that cost more than 200 yuan were basically made of carbon fiber, but there were differences in whether other materials were added, as well as the performance of the materials and the adjustment. Some high-end brands, such as Yonex, added other materials (such as tungsten) to the carbon fiber weaving to significantly improve the performance of the racket. Li Ning and Shengli also had similar practices. While watching the Olympics, you can also read the wonderful novels related to the Olympics!
What is the best racket?Aiya, it was hard to say. It depended on many aspects. For example, Yonex's racket was super famous. It had many high-end series and advanced technology. Many professional players loved to use it. Victory's racket is also very good. It's cost-effective. Some of its models are very suitable for amateur experts. There's also Li Ning's racket. Its racket design is very unique. It has a fashionable appearance and good performance. It's a good choice for our domestic fans. However, which one was the best would depend on your skill level, playing style, and budget. While watching the Olympics, you can also read the wonderful novels related to the Olympics!
How to choose a racket?Choosing a racket could be considered from the following aspects:
** 1. Weight **
1. ** Weight Range and Characteristics **
- The 3U shuttlecraft weighed between 85 - 89.9 grams. It was heavier, had a large inertia when hitting the ball, and had a large killing force. It was suitable for players who liked to kill the ball, had a large strength, and pursued a violent killing force, especially offensive players.
- The 4U shuttlecock weighed between 80 - 84.9 grams. It was relatively light and effortless to use. It was not easy to get tired after playing for a long time. It was fast to swing and was suitable for players who focused on defense and pursued reaction speed. For example, players who often played doubles in the middle and front. It was also suitable for beginners. It was the current mainstream choice.
- The 5U (75 - 79.9 grams), 6U (70 - 74.9 grams), 7U (65 - 69.9 grams), and 8U (60 - 64.9 grams) were lighter. Among them, the 5U was used by more people. The lighter racket was more flexible and had a better effect on some fast and agile plays in doubles. At the same time, it was more outstanding in defense. However, because the head was light, the attack was a little worse.
2. ** Choose according to your own situation **
- For beginners and players with average strength, it is recommended to choose a 4U racket, and beginners with great strength can consider a 3U racket.
- Players who were good and liked to kill the ball could choose a 3U weight racket, and if they were not sure how to choose, a 4U racket was a safer choice.
** 2. Pounds of wire **
- The higher the weight, the better. It had to be determined according to one's own strength. As time passed and skills improved, the weight could be gradually increased. Blindly using a high-weight racket would not only reduce the attack power of the ball, but it would also easily sprain the wrist due to the racket's vibration.
** 3. Racquet type **
- If it was for leisure and entertainment, and the pursuit of durability, choose a durable racket of about 100 yuan (usually a pair).
- If you want to learn the techniques of shuttlecock as a hobby, choose a carbon racket that weighs between 3U/4U/5U (75 - 89g)(4U is 80 - 84g) and costs about 200 yuan.
- Players who have a certain foundation and know their own playing style (such as offensive, speed, and balanced) can choose a speed, offensive, or both offensive and defensive racket that is suitable for advanced players between 300 and 900 yuan.
- Players who had a certain foundation, knew how to exert strength, and could understand the characteristics of the racket through trial play could choose a high-end racket that cost around 1000 yuan or more.
** 4. Other aspects **
1. ** Raider elasticity and hardness **
- If the middle club is too soft, it is difficult to control the ball. If it is too hard, the elasticity will be reduced and it will easily cause wrist and elbow joint injuries. It is more suitable to use "medium hard" or "hard"(8.0 - 8.5).
2. ** Slap handle size **
- The thickness of the handle was generally represented by G, which was divided into G0- G5. The larger the number, the thinner the handle, which was more suitable for players with small hands.
3. ** Slap face **
- The shape of the racket surface was a round head racket and a square head racket. Round-head rackets generally had a smaller sweet zone, but the power of the sweet zone was very concentrated, which was difficult for beginners to use. The square head rackets had a larger sweet zone than the round-head rackets, which was easy to control, but the hitting point was not so precise.
4. ** Material **
- At this stage, almost all the rackets priced above 100 yuan were made of carbon fiber, but the higher-priced rackets had a higher grade of carbon fiber, which was more outstanding in the elasticity, feel, and stability of the racket.
5. ** Torsion Resistance **
- The anti-twisting force referred to the magnitude of the twisting force produced by the racket when it hit the ball. The smaller the twisting force, the better the control of the ball.
6. ** Balance Point **
- The balance point could be understood as the center of gravity of the racket. The balance point was close to the top (head-heavy or offensive type), so it was more powerful, faster, and more inertia when hitting, which was suitable for offensive players. The balance point was close to the handle, so it had strong flexibility, which was suitable for defensive players. In order to avoid injury, if a new player wants a racket with a forward balance point to enhance his ability to return the ball and kill the ball, it is recommended to choose a racket with a slightly softer pole.
