non woven abrasive molding method according to the needs of different commonly used are the following : A hydraulic molding hydraulic molding equipment hydraulic machines and hydraulic press , because oil has the proper viscosity, not prone to back and stable, so abrasive molding is generally used hydraulic machine without water presses, such as the use of appropriate structural hydraulic machine can have ease of lift . Allows ease of lifting the molding compound at the time of pressing the abrasive gases sufficient time to escape from the mold compound, and the material layer can have time to get up and down and reduce the wheel traverse uneven density , and reduced after moving the elastic effect, increasing the pressure to maintain a predetermined time to obtain better results ; this operation , but the lift is too slow , reducing productivity. Using high pressure into the 70s can get a higher density of the last century, the country has rough ring automatic molding machine, but it only applies to a single large production specifications , the SMEs do not apply. The former Soviet Union had given automatic machine design thinking in a certain data, the agency is turning its schematic . Its automatic machine with high pressure blower vacuum adsorption molding blank robot , some domestic plants are imitation of this robot moves rough , eliminating the flap procedure ( Figure 5 ) . In recent years, domestic research on automatic molding machine has made significant progress in Figure 6 is the factory producing ceramic abrasive 18- station automatic molding machine.
Mold industry is an important area of high-tech industries in recent years, the rapid development of China's mold industry , mold industry dependent on imports from the past towards independence subsidiary industry new industry . World mold production center is also to transfer to China , China has become the mold production and consumption country , mold companies new investment , the investment in processing equipment to account for 80%. According to statistics, in 2010 China's mold in total sales reached about 112 billion yuan over the previous year growth of more than 14% , while the national mold equipment market has exceeded 40 billion yuan , and also to the rate of about 20% growth per year. This shows that China's mold industry in the post-crisis period to obtain a better non woven abrasive recovery of growth , the growth rate has scaled double digits again . At present , China has the highest amount of mold in the world, many mold companies . Abrasives as mold production process consumables , demand in the coming years , and its application in the production process of concern. On the status of corporate mold : mold industry has a relatively broad market prospects, but on the current development of mold companies , due to the financial crisis, the domestic economic downturn and other factors, domestic and foreign orders significantly reduced, given the very low price most of the mold is difficult to sustain their livelihoods. Plus a variety of costs rising again , a majority of companies have mold face closure . Of course, this is not absolute, the mold industry with many other industries, the development of the phenomenon today has emerged differentiation. Phone companies that supply the mold business, for example , can make international and domestic brands of mold factory , they are busy, and again to expand the scale of production . To develop in the mold industry , must have sufficient strength , the introduction of the best mold production equipment , professional and technical personnel, in collaboration with major clients with continuous orders. Today, the domestic mold industry has also emerged a number of competitive mold manufacturing enterprises, the Guangzhou Pearl River Delta region has become China's mold industry is most developed, high tech area. If domestic mold companies together, division of labor, sharing of resources , to achieve the level of technology leap , concentrate on solving problems in this area , the mold industry out of the current adverse situation is not difficult. Common mold polishing abrasive tools: a bit of scale mold enterprise value at 550 million yuan a year , of which the proportion of abrasives of about 10%. Mold in the manufacturing process of polishing tools used are: sandpaper , Whetstone , velvet carpet round , grinding paste, alloy rasp , diamond grinding , bamboo, fiber Whetstone , round rotating grinding machine . Mold polishing process : 1 , rough polishing 2 , 3 semi- fine polishing , fine polishing polishing environmental requirements: polishing process should be completed in two separate workplace . That rough grinding and fine polishing processing location separate locations , but also to pay attention to a procedure to clean the surface of the sand left in the . After the general rough polishing , the workpiece to be polished clean rooms to ensure that the air is free of dust particles stick to the mold surface . If a more precise polishing must be absolutely clean space , because of dust, smoke, dandruff and saliva Mo are likely to scrap high- precision polishing surface. After the polishing process is completed , the surface dust protection work to do . When the polishing process is stopped , carefully remove all abrasives and lubricants to ensure that the surface is clean. Should then spray the mold surface rust coating . Polishing the surface of factors : 1 , the surface condition 2, the quality of steel 3 , 4 heat treatment process , the mold manufacturing technique polishing polishing process is a very important step , it relates to the quality and life of the mold , but also determines products their quality . Master works and polishing process , choose the right method and polishing abrasive products that can improve the quality and life of the mold , thereby improving the quality of products. Mold Factory to numerous requests abrasives products , such as mobile phone suppliers mold companies require high quality , mostly with foreign materials , specialized procurement from manufacturers. Abrasive products to enter the mold companies , the most important thing is the product quality is better , the service should be in place , followed by Price and human relations . For mold equipment supplier , the main requirement is a high precision mold enterprise , good material , good shelf life to timely repair, maintenance , and maintenance work.
