Investment casting can make use of most metals, most commonly using steel alloys, carbon steel,stainless steel, and tool steel. This process is beneficial for casting metals with high melting temperatures that can not be molded in plaster or metal. Parts that are typically made by investment casting include those with complex geometry such as turbine blades or firearm components. High temperature applications are also common, which includes parts for the automotive, aircraft, and military industries.

Our products cover a wide range of industries including train & Railway, automobile & Truck, construction machinery, mining machinery, forklift, agricultural machinery, shipbuilding, petroleum machinery, construction, valve and pumps, electric machine, hardware, power equipment and so on. We are capable to produce products according to customers' drawings or samples, we focus on both carbon steel and alloy steel. Up to today, more than 100 raw materials and 5, 000 kinds of different products have been developed and produced by us. We are familiar with the material standards of many countries, such as Chinese GB, American ASTM, AISI, German DIN, French NF, Japanese JIS, British BS, Australian AS and Association of American Railroads (AAR ) and other industrial standards.
The process is generally used for small castings, but has produced complete aircraft door frames, steel castings of up to 3 tons and aluminium castings of up to 100 kg. It is generally more expensive per unit than Die Casting or Sand Casting but with lower equipment cost. It can produce complicated shapes that would be difficult or impossible with die casting, yet like that process, it requires little surface finishing and only minor machining.
Investment casting is used in the aerospace and power generation industries to produce turbine blades with complex shapes or cooling systems. Blades produced by investment casting can include single-crystal (SX), directionally solidified (DS), or conventional equiaxed blades. It is also widely used by firearms manufacturers to fabricate firearm receivers, triggers, hammers, and other precision parts at low cost. Other industries that use standard investment-cast parts include military, medical, commercial and automotive.
Investment casting offers high production rates, particularly for small or highly complex components, and extremely good surface finish (CT4-CT6 class accuracy and Ra1.6-6.3 surface roughness) with very little machining. The drawbacks include the specialized equipment, costly refractories and binders, many operations to make a mold, and occasional minute defects.

Security surveillance camera analog and digital network installation are different?
Monitoring has become more and more important in life, and installation monitoring is a very tiring thing, and there are still different techniques. The early monitoring was mainly based on simulations. Of course, there are now, but the relative use is relatively small. The current trend is to install network monitoring.
The same point: Some materials are the same. The mounting brackets are all using 12V power supply. The camera's power interface is generally 12V power interface. Generally, video recorders are used.
difference:
1, the camera's interface is different, the analog monitoring connector is the use of BNC connector; the network camera uses the crystal head, which is the network cable to connect.
2, different wire: analog monitoring using coaxial lines, network cameras use network cable.
3, the video recorder is not the same: analog monitor using the video recorder interface is BNC connector interface, analog video recorder in order to achieve networking, also has a network interface, of course, you can also add a capture card on the computer, through the computer recording surveillance video; and network monitoring use The interfaces are all network cable interfaces.
4, the transmission distance is not the same: the use of coaxial line analog monitoring, generally within 300 meters can see the monitoring screen, and the line can be directly connected in the middle, but the final display may appear distortion of the screen. The use of network cable transmission network camera, the best cable distance does not exceed 100 meters, otherwise you may not see the video screen.
Other experience sharing:
1, on the fiber: regardless of the network camera or analog camera, in long-distance image transmission, can use fiber. Network and analog monitoring When using fiber transceivers, there are corresponding switching devices. The main use of switches in the network, analog monitoring also has corresponding devices, as shown below.
There is a problem with fiber splice. What should I do?
(1) You can find someone to help melt the fiber, you can pay some fees, it is best to use hot melt, it can not be considered cold.
(2) Do not use optical fiber, consider using the corresponding amplifier, analog monitoring amplifier, 500 meters of SYV-75-5 coaxial cable are no problem, you can clearly see the monitoring screen, this is Xiaobian encounter the most Remote analog monitoring, whether it can be more distant distance did not try.
Network monitoring can also be implemented using network amplifiers. Installing an amplifier at the camera can enlarge the maximum transmission distance of the network cable to about 300 meters.
Only the increase of these devices will increase the cost relative to the use of optical fibers.
(3) Optical fiber product lines can also be directly purchased. However, this requires the effect of welding. Many of the finished product lines purchased are mainly cold-welded, and some of them are not very good quality. Therefore, it is necessary to pay attention when purchasing a finished optical fiber product line.
About POE Power Supply Simulation Monitoring There is no POE power supply. One can only pull one power supply.
The network monitor can use a recorder with POE power supply. In this case, it is only necessary to pull a cable from the recorder to the recorder, and it is not necessary to re-pull the power. If you do not use a recorder with a POE, you can also use a POE-powered switch, which can also provide network cable power to the camera.
