General machinery parts output value has growth

China General Machine Components Industry Association has announced that General Machine Components Industry GDP grew only 6.4 percent last year, which is the lowest recent years, down from 12.1% in 2008. Fasteners and powder metallurgy industry even have negative growth of -1.5% and -2%. According to reports, General Machine Components industry output since 2006 has maintained a double-digit growth. China General Machine Components Industry Association said in 2012 the industry suffered the most difficult times in recent years, compared to the global financial crisis in 2008, the more serious problems encountered by industries and enterprises.

Founded in 1989, China General Machine Components Industry Association (CMCA) is a registered national industrial organization having the social entity as a legal person with the approval from the Ministry of Civil Affairs. It is voluntarily formed by the manufacturers, research institutes and related associations in the fasteners, gears, chains transmission, springs, powder metallurgy, and couplings industry.

In the complex domestic and foreign downturn grim development situation, on the one hand, enterprise development funding significantly increased; on the one hand, there was a dramatic decrease in corporate profits. Besides, fasteners suffered the international trade protection impact which results in the range of exports narrowed significantly; less order, upgrade, products optimization, green manufacturing, lack of funds, labor drain and other series of problematic issues, are pooled together in 2012.

China General Machine Components Industry Association also said that in last year, precision hardware has growth totally. The gear output value reached 195 billion yuan, a year-on-year increase of 9.5%; gear exports is relatively stronger which is $ 4.543 billion with an increase of 18.3%; precision parts manufacturer said that chains, springs and transmission joints basic sub-industry growth rates is 8%; however, fasteners, powder metallurgy industry has emerged negative growth, year-on-year growth of between -1.5 to -2%.

Association reported that the reason why fasteners and powder metallurgy industry has negative growth is that lack of market demand. Especially fasteners are suffered by the international anti-dumping, which caused export sales showed a downward trend.

However, China General Machine Components Industry Association believes that, the development of the industry has switched from the high-speed growth stage to the high-quality and stable growth period. And “from the forecast analysis trend of economic development in 2013 at home and abroad, the industry should be better in 2013 than in 2012”.

Introduction to 304 Stainless Steel

304 stainless steel is a very common type of stainless steel, also known as eighteen-eighths stainless steel in this industry. Corrosion resistance of it is preferable to that of 430 stainless steel, but the price of it is cheaper than that of 316 stainless steel. 304 stainless steel is widely used in daily life, such as: high grade stainless steel cutlery, outdoor stainless steel railings and 304 stainless steel coil products.

Although this type of stainless steel is very common all over the world, but the name "304 stainless steel" came from the United States. Many people think that the 304 stainless steel is a model called in Japan, but strictly speaking, Japanese official call of 304 stainless steel is "SUS304". Currently, common indicating methods of this type of stainless steel on the market include 06Cr19Ni10, 304, and SUS304. Among them, 06Cr19Ni10 generally means Chinese standard production, 304 generally means ASTM standard production, and SUS304 means JIS standard production.

304 is a universal stainless steel. It is widely used for making equipment and parts require for good overall performance (corrosion resistance and formability). In order to maintain the inherent corrosion resistance of stainless steel, steel must contain more than 16% chromium and over 8% nickel content. 304 stainless steel is a mark of stainless steel produced in accordance with United States ASTM standards. 304 is equal to 0Cr18Ni9 stainless steel in China. (GB/T 20878-2007 has been changed to 06Cr19Ni10).

Product Standard

It is a very important parameter for 304 stainless steel, directly determining its ability to resist corrosion and its value. The most important element of 304 stainless steel is Ni and Cr, but they are not the only two elements. The specific requirements are stipulated by the product standard. Industry common decision situation finds that as long as the content of Ni is greater than 8%, and the content of Cr is greater than 18%, it can be regarded as 304 stainless steel. That's why this type of stainless steel is called eighteen-eighths stainless steel in this industry. In fact, related product standard has very clear rules to 304, which is different to stainless steel of different shapes.

Situation of China Rare Earth Industry

China is playing games with modern electronic equipment and REE export quota cuts per cent of exports are necessary, so that the industrialized countries scrambling everything from smart phones to the laser-guided weapons material.

This latest reduction in exports comes on the heels of a whopping 72 percent cut in rare earth metals earlier in the year, driving up prices.

New quotas, this may be the year to adjust, more and more international focus on the availability of the metal, which 97% of production in China. "

"Beijing has been gradually reducing exports of rare earths, and the reason is the increase in domestic demand and environmental issues. Soared after Japanese rare earth manufacturer reported earlier this year, is cut off diplomatic dispute process shipments from China between international interests ."

Chinese control of not less than 95% of global rare earth production. In this high-risk game Baotou Steel Rare Earth Group Hi-Tech Co., Ltd., the production of key players from Inner Mongolia - the world's largest rare earth elements. China has imposed export quotas for rare earth three years - in order to improve their own high-tech industries. The Chinese master plan is to develop sophisticated smelting techniques for rare earth – instead of simply selling the raw product.

The end of last year, the U.S. Department of Energy lists five "key" rare metals production of clean energy; dysprosium, neodymium, terbium, europium and yttrium. Hybrid cars and fiber are essential, such as production.

From the Pentagon's perspective, it is more important to the mountains of the U.S. industrial military complex aircraft engines and missiles of rare earth metals. Once again, China is the world's only rare earth supplier.

In 2025, the United States will be mainly determined by China to access these rare earth metals. There are three ways, the development of alternatives to improve the recovery or increase the local production of rare earth - for example, in a huge mining investment amounted to $ 5,000,000 in California.

www.rareearth-china.com is committed to the production, research and development, sales ceramic raw materials and cerium oxides and other rare earth materials for chemical industry, as well as chemical raw materials for glass-ceramic.

Types of Door Lock Handle

Two Points of Large Difference of Price

Price difference mainly shows on these two points: one is the brand, and the other is styling. The reputation builds brand, and quality supports reputation. Famous brands are definitely with superior quality. Nowadays in the building materials market, most of those upscale door lock handles are imported, especially mainly from Germany, such as Hoppe, Hafele, and DEBON. According to different models and styles, door lock handle prices are most in between 600 Yuan to 3,000 Yuan, as well as 6,000 Yuan to 8,000 Yuan or even luxurious type costing tens of thousands Yuan; mid-range door lock handles mainly come from joint ventures, Taiwan, China or Guangdong, China. There are JIADE (joint venture), Taiwan ZMT, Guangdong FUYU, and FUANTE, etc. Their prices are in between 300 Yuan to 600 Yuan; low-end door lock handle price is below 100 Yuan, generally between 60 to 90 Yuan.

There is also a cheap door handles of the twenty or thirty dollars, materials and workmanship is very rough. Quality is the same or close to the door handles, from one model to another, prices vary. In General, bar door handle expensive than spherical one hand, feel better; finish higher, the higher the price. Also has a model perfectly "shaped" door handles, a Tarantula, a lizard in Africa or a carp jumped the Dragon Gate, are likely to become your family door handles. "Special" door handles can also be customized, such as a celebrity's hands, so that you once, and admired figure in the eyes of you "hold your hands", exhilarating. Or as far afield as a lover's hand in a foreign land, and also had a unique flavor. However, it may have to make you money. "Special" is expensive, typically thousands of million.

Buy Door Lock Handles According to Circumstances

As to home, everybody wants to use the money on the blades. For your new home purchase a suitable and cost-effective door handle it? In a Word, suit measures to local conditions. Simply must be solid, such as household insurance, with the Ministry of public security-approved best, interior doors more beautiful and convenient. Bedroom door, living room door is not closed or locked, to buy number switch guarantees less, 100,000 in General would have been enough, 200,000 times was a bit "overkill" and the bathroom door lock, high frequency switch and lock, would like to buy good quality, frequency of switching high door knobs.

In addition to this, health factors cannot be ignored when buying door lock handles. For example, brass door lock handle is suitable for washrooms. Because it seems stainless steel door lock handles are clean, but in fact they can breed thousands of germs, including Glenn's bacteria, Escherichia coli and streptococcus. Bacteria on the brass door handles are much less than that on stainless steel door handles, because brass can destroy bacteria. Therefore, it is best to install brass door handles of the bathrooms in your home, which is good for your health.

The Price of Fasteners Affect the Development of the Common Standard Parts

The phenomenon of excess production capacity and raw materials skyrocketing will appear in the fasteners and other basic components industry. Everyone said capacity refers to the common standard parts (less than 8.8 fasteners) should develop restrictively. Recalling the history of Stainless Steel Fasteners and other basic parts industry found a regularity phenomenon whenever the market, followed by an inevitable product saturation, followed by the macro-control and compression, followed by a short supply, the manufacturers again on large capacity, so the product again saturated, so the cycle fastener industry for nearly 20 years.

It is not difficult to see, different situations have the different enterprises and the corporate capacity is indeed manifested as surplus. With an internal, product demand, product sales are sluggish. Therefore, cannot be generalized problem of fasteners such as the capacity of the infrastructure components the general overcapacity or excess biased, survival of the fittest, innovation, and a sign of the healthy development of the industry.

Overcapacity, product saturation is accompanied by the continuous rising of cold heading steel wire rod, in fact, the trend of raw material towards is the impact of the international environment. And since 2010, global iron ore prices were rising step by step and the iron ore prices soared 71.5% in 2012, is still expected to rise 10% this year, now commonly used cold heading steel swrch35k of up to 3900 to 4400 per ton, 45 # carbon steel up to 3400 to 3800 per ton last month rose from 500 to 800 per ton.

The main reasons for the recent steady trend of raw material prices: First, control steel industry production capacity to ease the relationship between supply and demand, and the countries strengthen macro-control of the iron and steel and high tensile fasteners industry, the steel market develops orderly. Second, the decline in steel imports and exports are increasing, which is conducive to price stabilization. In addition, market confidence has been restored, operators and production customers are optimistic about the market demand, and dare to procurement.

Fasteners and other basic parts industry are the raw materials industries dependent on the raw materials and the increase of raw materials will naturally enhance the cost of production of fasteners. In the current situation, fasteners and other basic parts manufacturers should timely adjust the product structure, control the scale of investment and compress the non-productive expenditure, which undoubtedly have a positive sense.

In addition, in order to save material expenses fasteners and other basic parts industry have to put into the technology, and only the good technique can also open up wider market resources.

Basic Knowledge of CNC Machines

Numerical control (NC) is the automation of machine tools that are operated by abstractly programmed commands encoded on a storage medium, as opposed to controlled manually via handwheels or levers, or mechanically automated via cams alone. The first NC machines were built in the 1940s and 1950s, based on existing tools that were modified with motors that moved the controls to follow points fed into the system on punched tape. These early servomechanisms were rapidly augmented with analog and digital computers, creating the modern computer numerical control (CNC) machine tools that have revolutionized the machining processes.

In modern CNC systems, end-to-end component design is highly automated using computer-aided design (CAD) and computer-aided manufacturing (CAM) programs. The programs produce a computer file that is interpreted to extract the commands needed to operate a particular machine via a postprocessor, and then loaded into the CNC machines for production. Since any particular component might require the use of a number of different tools—drills, saws, etc., modern machines often combine multiple tools into a single "cell".

CNC machine tools are generally composed by the following precision machined parts: 1. Host machine. This is the subject of CNC machine tools, including the mechanical parts of the machine itself, column, spindle, and feed mechanism. It is used to complete a variety of machining mechanical parts. 2. CNC devices. It is the core of CNC machine including the hardware (printed circuit boards, CRT monitors, key boxes, paper tape reader, etc.) as well as the software which is used to enter the number of the part program, complete the input information storage, data transformation, interpolation computation, and achieve a variety of control functions. 3. Driving parts. It is the drive of the CNC machine actuator including the spindle drive unit, the feed unit, the spindle motor, the feed motor, etc. Under the control of the NC device, by electrical or electro-hydraulic servo system, the spindle and feed drive. When several feeds are linked, positioning, line, plane curves and space curves can be processed. You can get custom machined parts as well. 4. Auxiliary device. It means some necessary supporting parts to guarantee the operation of CNC machine, such as cooling, chip removal, lubrication, lighting, monitoring, etc. It includes hydraulic and pneumatic devices, chip conveyor, exchange table, CNC rotary table and CNC dividing head, tools and surveillance detection devices. 5. Programming and other ancillary equipment. They are available to program and storage the outside parts of machine.

CNC Tools include: Drills, EDMs, Lathes, Milling machines, Wood routers, Sheet metal works (Turret Punch), Wire bending machines, Hot-wire foam cutters, Plasma cutters, Water jet cutters, Laser cutting, Oxy-fuel, Surface grinders, Cylindrical grinders, 3D Printing, Induction hardening machines, and so on.
