Starting with assembling shredders, Kemi has now become the largest shredder manufacturer in China, and has also established a number of product lines, including binding machines, attendance machines and other machines, and has won the top ten brands of office supplies in China in 2011 and won the China Best-selling Stationery Brand Award for two consecutive years.
 
Like Van Ross, the company focuses on shredders, and pays less attention to binding machines, although there are two binding methods, rivet and comb, but there are not many models. Same as Huijin, there is no manual model of the riveting tube binding machine of the Ministry of Secrets, there are two types of semi-automatic and fully automatic respectively, the performance of the machine is good, but there is no advantage in terms of price, and the cost performance is average.
 
Semi-automatic models have CM-50N and CM-50A, positioning are entry-level, in addition to the appearance, the difference between the two is not big, the binding thickness is 50mm, equivalent to about 500 sheets of paper, the warm-up time is 2-4 minutes, in the industry at the medium level. It is more recommended to sell the CM-50N, which is about 1700 yuan, which is about 500 yuan cheaper than the CM-50A, and is relatively more cost-effective.
 
CM-500K and CM-500A are fully automatic models, which can complete drilling and binding with one click, the binding time is only 30 seconds, and the drill cutter has high durability, and the official claim has passed 30,000 punching tests, while the average brand only passes 10,000 punching tests. CM-500K and CM-500A are priced at 7000/9000 yuan respectively, the performance is not much different, but the latter has one more LCD screen than the former, but the price is 2000 yuan higher, not very cost-effective, and the price of 9000 yuan can buy first-line brand Huilang, Jindian products, more recommended cost-effective CM-500K.
 
There are also two types of comb binding machines in the ministry, but they are not worth mentioning, many users evaluate that "it is easy to have some small problems", it can be seen that the quality needs to be improved, and there is no matching rubber ring and clamp strip for sale, you need to buy from other brands, the comb binding machine product line is not its strong point, and it is not a good choice.
