In recent years, we have seen the rapid development of science and technology in our great motherland. This made me feel extremely proud for me as a Chinese. With the advancement of technology and the progress of people, we will join the Chinese cutting machine trading network to make progress together. Join the hotline, we look forward to your call.

Sodium hydroxid,with the chemical formula NaOH, is commonly known as caustic soda. It is a strong alkali with strong corrosivity, generally in the form of flakes,pearls or lumps.Industrial grade Caustic Soda contains a small amount of sodium chloride and sodium carbonate, and is white translucent crystal.Its aqueous solution has an astringent and creamy feel.Sodium hydroxide is prone to deliquescent in the air, so solid sodium hydroxide is often used as a desiccant.It is very soluble in water and emits a lot of heat when dissolved. It`s also soluble in ethanol and glycerin.
Sodium hydroxide (NaOH) is extremely versatile. Used in the production of paper, soap, dyes, rayon, metal smelting, petroleum refining, cotton fabric finishing, coal tar product purification, and food processing, wood processing and machinery industries.
The product is a strongly alkaline substance which belong to 8 grade dangerous goods. with strongly irritating and corrosive, dust or smoke can irritate the eyes and respiratory tract, corrode the nasal septum, direct contact between the skin and eyes and NaOH can cause burns, and misuse can cause digestive tract burns, mucosal erosion, bleeding and shock.So it`s highly corrosive and requires the "corrosive item" mark.

There are more than 40 companies that produce cutting machines in the country, mostly private, individual, and joint-stock companies. The statistics of the welding and cutting machines in 2000 were 380 gantry cutters, 14650 car cutters, 10500 plasma cutters, 2.5 million welding torches, and 1.89 million cutting nozzles.
The development of CNC cutting industry in China is relatively late. There are more than a dozen CNC cutting machine manufacturers in China. The annual market demand is about 350-400 units, which basically meets the needs of the domestic market. The imported products are less than 10% of the total market. At present, the domestic manufacturers of CNC cutting machines mainly include Shanghai Isa Cutting Machinery Co., Ltd. and Messer Cutting & Welding Co., Ltd. (Kunshan). They have received strong technical support from foreign technology, so the products are in a leading position in China. Harbin Sihai Numerical Control Equipment Co., Ltd., Harbin Welding & Cutting Equipment Co., Ltd., Harbin Electric Machinery Co., Ltd. Machinery and Electronic Equipment Manufacturing Plant, Shipbuilding Technology Research Institute of China Shipbuilding Corporation, Shenzhen Bolichang CNC Cutting Equipment Co., Ltd., and Wuxi Hualian Welding and Cutting Equipment Companies and other companies use the advantages of their own companies and have developed rapidly in technology. Products meet the needs of different users.
The product development in China's cutting industry has broken the traditional boundary between welding and cutting. Its products have already crossed the two major industries of welding and cutting. Many companies also produce welding and cutting equipment.
Problems with the cutting machine industry:
(1) The disorderly competition in the market is characterized by devaluation, mutual price reduction, and mutual digging;
(2) Little or no R&D investment, or no input at all;
(3) There is not much difference with foreign products in the level of machinery and control, but it is not transparent to foreign control systems and only stays at the level of application;
(4) There is no cooperation between companies and they cannot be united to open up the market. For example, the concentration of companies on the procurement of parts will reduce costs.
