Zhejiang Qichen Electromechanical Co., Ltd., with 15,000 square meters of modern factory buildings, is an advocate of high-end silent mahjong machines. 

From the era of hand-rubbing mahjong to stand-up machines, noise has always been the most disturbing part of mahjong, especially mahjong friends prefer to play mahjong all night, the noise of shuffling cards makes relatives sleepless, and it affects the harmony of neighbors, and the neighborhood disputes and even criminal incidents derived from it abound. 

The noise of the mahjong machine mainly comes from two parts: the motor and the shuffle barrel. The mainstream four-mouth machine generally needs 14 motors, and the price of a single motor with good quality is 30 or 40 yuan, while the inferior motor only needs about 10 yuan. In addition to the material, the heat resistance level, protection level, and bearing quality of the envelope all affect the quality of the motor. A good motor is efficient and stable when running, and the sound emitted is also small, while the products of Qichen are all customized motors, which are close to silent when running. 

In addition to the motor, the collision between mahjong and the inner wall of the shuffle barrel is also a major source of noise, the general manufacturer will paste the anti-collision sound-absorbing material on the barrel wall, and the morning is more detailed, in all the transportation channels of mahjong have added the noise reduction process, the noise of the whole machine is suppressed to below 30 decibels, which belongs to the excellent level in the industry, but it is not much better than other brands. 

In terms of products, the prices of the main products of Quechen are around 3000 yuan, and the most popular ones are QQC005 and Q7. Compared with products at the same price, the appearance design of Qichen is at the middle and upper level, and the more practical mobile phone slots, USB charging ports, and large-capacity drawers are all available, which are very cost-effective.
