Tube cutting machines are used for cutting long metal stock or scrap, generally where accuracy is not an important consideration, and the size or shape of the material makes other cutting or shearing options (such as a cutting torch) impractical. Alligator shears are often used in conjunction with large metal shredders in the metal recycling industry, to [clean" or prepare scrap for shredding by removing unwanted fittings and other parts the Shredder will not accept.

In 2011, automotive MEMS sales reached US$2.2 billion, an increase of 16% from the US$1.9 billion in 2010. Last year, it maintained a momentum of a 28% surge in 2010, when the market accelerated its way out of the global recession. The growth rates in 2011 and 2010 were above average, even higher than the usual growth rate of 7-9% before the previous recession.
As the market enters a growth phase, more good news will come out. The market is expected to grow at a faster rate than initially expected. From 2010, the five-year compound annual growth rate is about 10%. This means that by 2015, the automotive MEMS industry sales are expected to exceed the 3 billion US dollars mark.
The four categories are major contributors to automotive MEMS sales: pressure sensors, accelerometers, gyroscopes, and flow sensors. The four devices accounted for 21 of 24 automotive MEMS applications and accounted for almost 99% of the entire automotive MEMS market.
The main growth drivers for this market are still government safety regulations requiring the use of MEMS sensors such as the Electronic Stability System (ESC) and Tire Pressure Monitoring System (TPMS). Among the major sensor vendors with extensive focus on security, Bosch, Sensata, Analog Devices, VTI and Freescale Semiconductor reported that their market share has grown, and that the overall automotive sensor growth rate at the end of the year is much higher than 15%. rate. First-tier manufacturers such as Continental, TRW and STMicroelectronics and other semiconductor companies have confirmed similar growth rates.
The rejuvenation of the automotive industry and the increase in production are another factor in the growth of the automotive MEMS market. Although last year's car output was only 3% higher than the special growth rate of 25% in 2010, the increase in overall car production was enough to push up the overall inventory level of automotive MEMS sensors. At present, the output of automobiles has exceeded 75 million. The sales of light passenger cars is a key factor.
The third factor influencing the growth of automotive MEMS is somewhat unexpected: the Great Japan Earthquake in March 2010 and the floods in Thailand in October 2010. System supplier's supply chain logistics seems to have withstood the test of these disasters. However, these manufacturers, who have also experienced the impact of the 2009 recession, are aware of the significance of expanding the number of sensors. This multi-supply supply agreement creates opportunities for new and old automotive sensor suppliers. Compared with the consumer electronics supply chain, car supply agreements have been relatively stable so far.
Outlook for 2012, Japan's Impact IHS believes that due to inventory cuts by manufacturers in the late second half of 2012, sales growth is expected to decline slightly this year, to about 7%. However, it is expected that automobile shipments will increase by 6%, which will offset the decline in inventory, and the impact of safety regulations will increase. For example, an electronic stability control (ESM) system can account for approximately $15 in the value of each automotive MEMS sensor.
This year Japan will also implement the ESC safety regulations in the country. It is expected that Japan will introduce relevant regulations in October, which is about the same as the expected time in Europe. The new model will be equipped with ESC to detect the deviation between the driver's intentions and the actual movement of the car. The ESC system can automatically intervene when it is necessary to prevent dangerous slippage.
By 2014, all existing Japanese cars and all new mini cars will have ESC installed. The mini car is a local automobile category in Japan, with a length of less than 3.4 meters and a displacement of 660 cc or less. According to IHS Global Insight, Japan’s ESC regulation is expected to affect a total of 5 million vehicles in 2012.
