"Top Gun" is an air-powered pitching machine that reproduces real-life pitching and achieves high performance. It allows for various types of breaking balls and changes in ball rotation, based on the same principles as actual pitchers' breaking pitches. It enables safe and easy infield/outfield defensive practice. Additionally, unlike conventional machines that require you to look straight down from above to time your swings, this machine allows you to predict actual arm movements based on the ball's motion, making it easy to practice important timing. 【Features】 ■ Accurate control and revolutionary breaking ball function ■ Defensive practice is also possible ■ Outstanding safety and durability ■ Allows for more practical batting practice with angled pitches ■ Release point can be adjusted from approximately 1 to 1.7 meters *For more details, please refer to the PDF document or feel free to contact us.

We would like to introduce the key points of the introduction of 'Top Gun' handled by Kōwa Giken. In the world of professional baseball, nothing surpasses a ball thrown by a person. However, for those involved in amateur baseball and batting centers, there has never been a machine that resolves issues such as "the lack of batting pitchers" and "the inability to hit a large number of balls with similar speeds and types." Therefore, our company has developed a machine that meets the demands of various stakeholders. We aim for a robust design that can deliver balls at around 150 km/h and produce over one million pitches, and we are verifying durability with a test machine that can reach 300 km/h. 【Development Process】 ■ A machine that is safe, high-performance, and durable is needed. ■ Faithfully reflecting user feedback, we enhance specifications as an industrial product. ■ We aim for a robust design that can deliver balls at around 150 km/h and produce over one million pitches. ■ We verify durability with a test machine that can exceed 150 km/h by more than double (300 km/h). *For more details, please refer to the PDF materials or feel free to contact us.

The full-scale development of our air pitching machine began from the perspective and requests of users, specifically from local professional baseball teams, who asked, "Can we replicate the pitches of professional pitchers?" Conventional pitching machines have faced challenges in terms of safety due to their structure, which leads to issues with ease of handling, durability, and unstable accuracy, resulting in wild pitches. In this context, the demand for our developed machine, which addresses issues such as accuracy, convenience, and machine durability, has started to increase. There are expectations for market penetration not only from direct purchases by users but also from sports stores in various regions and major sports manufacturers. [Reasons for Being Chosen (Partial)] ■ Accurate pitching and diverse functions are superior compared to conventional models ■ Does not crush or pinch the ball during pitching ■ The seams of hard balls are less likely to break, resulting in less wear on the balls ■ Low risk of accidents due to the absence of high-speed moving parts ■ Simple structure makes it easy to understand the construction *For more details, please refer to the PDF materials or feel free to contact us.

Our company handles the air-powered pitching machine "Top Gun." There are three types of pitching machines: "air-powered," "arm-type," and "rotor-type." The "air-powered" type stabilizes the ball trajectory by passing through a launch tube, while the "arm-type" requires adjustments due to changes in ball trajectory caused by the loosening of springs, etc. Additionally, the "rotor-type" may deliver unpredictable pitches depending on the grip of the rotor. 【Features】 <Air-powered> ■ Accuracy (capable of precise pitching to the targeted area) ■ Safety (no high-speed moving parts) ■ Convenience (easy adjustment of speed, course, release point, and breaking balls) ■ Versatile functions (varied breaking balls with trajectories similar to actual pitchers) ■ Durability (less metal fatigue, energy-efficient) *For more details, please refer to the PDF document or feel free to contact us.

"Top Gun" is an air-powered pitching machine that pursues control, safety, and durability. By allowing speeds from 80 to 170 kilometers per hour and adjusting the height in 32 levels, it meets the demands of a wider range of customers. The random function also enables practical training. With the addition of value elements (such as baseball classes) to existing batting centers, users can experience fastballs similar to those thrown by professional pitchers in videos. 【Features】 ■ Accuracy (the balls that can be hit come) ■ Safety (no high-speed moving parts) ■ Convenience (no wild pitches, and adjustments take little time) ■ Versatile functions (speed, breaking balls, etc. can be easily adjusted with a dial) ■ Durability (cost reduction) *For more details, please refer to the PDF document or feel free to contact us.

In the world of professional baseball, it is believed that "there is nothing better than a human pitcher throwing the ball," such as during batting practice conducted by a batting pitcher. However, the reality of amateur baseball includes issues like "a shortage of batting pitchers" and "the inability to hit a large number of balls with similar speeds and types." Therefore, our company believes that there is a need for a safe, high-performance, and durable machine, and we have worked on developing machines that meet the requests of all stakeholders. 【Reality and Requests】 ■ Amateur Baseball - There are few batting pitchers. - It is not possible to hit a large number of balls with similar speeds and types. - Players must also get used to fastballs around 150 km/h. ■ Batting Centers - There is a need for machines that have fewer moving parts and maintenance, and can consistently deliver fast balls. - Machines used by baseball teams are used about ten times more than those in batting centers. *For more details, please refer to the PDF document or feel free to contact us.
