Future trend of RMB-Easy credit

According to the credit data published on last Friday, the amount of credit in July increased by 1.45 trillion, an increase of 323.7 billion RMB year-on-year.

On Saturday afternoon, China Bank Insurance Regulatory Commission has published a special article about “To enhance the supervision and guidance, open up the transmission mechanism of monetary policy, and improve the economic level of financial services”. This article stresses that the bank should increase the credit supply and loan support for small and medium-sized enterprises.

Obviously, the transformation from Cemented Tungsten Carbide easy money to easy credit has been realized in July. As the scale of credit expands further, the decline of the general lending rate and the notes financing rate will further accelerate, and the economic will gradually be stabilized.

Reduction of interest

According to the statistics published by the Central Bank, it shows that money market interest rate has continued to fall in the past two months. Last week, the rate of bank overnight was 1.622%, and the interest rate on August 7th closed at 2.450%. Both fell compared to the same period last week.

Forecast of exchange rate trend

Since the exchange rate is regarded as the value of one country’s currency in relation to another currency. Therefore, we have to look at the recent actions of the dollar in order to analyze the trend of RMB:

1) cemented carbide blade Expansion of national debt scale

Due to the increase in the US social welfare and the military spending, monetary policy of the United States is relatively tight. On July 30th, the U.S. Treasury Department said that it expects the third quarter debt to be $56 billion higher than previously estimated amount. The total debt is $329 billion.

2)Increase of government bond interest rate

“In general, what we’ve seen is the Turkish lira deprecation significantly against the dollar ... Trade tensions have kind of kept Treasury in a range for some time,” said Charlie Ripley, senior market strategist for Allianz Investment Management. “We also kind of expected more upward pressure on Treasury yields with the increased auction sizes, but it seems every time it seems to be met with demand. It’s sort of a head-scratcher.” 

Moreover, according to the recent statistics, the Fed’s increase of interest rate in September is a high probability event.

Forecast of RMB exchange rate trend

Hence it is obvious that China and the US have taken different methods. China has loosened the monetary policy and lowered the interest rate. On the contrary, the US has tightened the money supply relatively and raised the interest rate moderately. Therefore, through the analyses from all aspects, we conclude that the trend of the continued depreciation of the RMB against the US dollar will not end in the short term.

Tungsten Carbide Helix Rod

Tungsten carbide helix rod has high hardness (typically between HRA85 ~ 93), high strength (the compressive strength of 3400MPa ~ 560OMPa, flexural strength is 750MPa-2500MPa), high wear resistance (15 to 20 times higher than the best HSS), high heat resistance, strong antioxidant capacity and a series of advantages. It can be used to produce a variety of drills, high-speed milling tools .

 

 

 

 

 



Tungsten Carbide Helix Rod Production Process
Tungsten carbide helix rod manufacturing technology key is the helix hole formed, it mainly made by a metal powder injection molding technology. The process is: the mixture of metal powder Tungsten Carbide Round Rod and wax injection molding, and then paraffin is removed by sintering to obtain a high density tungsten carbide helix hole rods. Metal injection molding process as follows: mixing→glue→injection material→injection molding (mold)→green→lifted binder sintering→product. Metal powder injection molding production of tungsten carbide helix rod has high efficiency, high quality, precision, low power consumption advantages.

Tungsten Carbide Helix Rod Processing Methods
1. Billet processing method. The carbide bar prior to sintering the green compacts in drilling, the other end of the drilled hole at the same angle of 2-4.
2. Mosaic Law. This method is called sandwich method, sintering combination method. That is processed into a spiral flute carbide rod surface, and then pressed into a hard metal pipe sleeve compacts and then sintered together.
3. Squeeze method. The plastic compound mixture is extruded through a cut of the spout, the spout end of the installation of a large cylindrical hole formed spiral teeth containing these small teeth produce a rotating spiral during extrusion material through the formation of spiral groove slot.

Tungsten Carbide Double Helix Hole Rod Production Technology
Tungsten carbide double helix hole rod forming a double helix hole in the mold of its rough twisted to form a rotation, extrusion faster, shorter rough time in the mold mediator shape after extrusion die, the degree of elastic recovery, the greater the rough , while the longitudinal expansion is the result of the pitch increases. Therefore, the faster the extrusion speed, the greater the pitch of the blank.
Tungsten carbide double helix hole rod production technology, there are two that way and within the outer helix extrusion helix extruder way. The so-called outer helix extrusion way in the mold design and manufacture, the use of the female mold die with a ribbed tank, forcing the fluid out of the material change direction, rotating manner extruded billets, extrusion billet to rotate the entire process manner. So-called inner helix extrusion methods, the use of the special structure of a twin-helix extruder, and the core rod extends through the extrusion helix. Use a helix drive to reach the spiral mandrel rotation effect.

Tungsten Carbide Helix Rod with Cooling Holes
Tungsten carbide helix rod with internal cooling helix hole drill is mainly used in the production. Carbide drill with internal cooling helix holes, deep processing can improve the efficiency of drilling difficult materials to meet the needs tungsten carbide cutting tools of automatic processing lines and machining centers. In the cutting process, we can promptly get rid of metal debris in the working plane, extend the life of carbide tools, reducing replacement time, can greatly improve the processing speed. Internal cooling process is through an internal spiral tunnel, cutting edges will be transferred to high coolant under pressure. This can be either a spiral channel of the coolant due to the rapid and timely delivery, and rapid decrease in the process temperature; the same time as it directly to the internal processing of the front channels, which can be produced mechanically debris quickly and timely and clean out. Thus, it can achieve significant practical effect, its application both to extend the service life of their own, but also shorten the time the reorganization of machinery and tungsten carbide rods equipment.

Tungsten Carbide Scribe Makes Life Easier

A carbide scribe may seem like an obscure tool, but it's not. What the carpenter's pencil is to building houses, the tungsten carbide scribe is to building with metal. As anyone who has marked metal will tell you, a pencil doesn't work and neither do most pens. If you can get a pen to make a line, it can easily be smudged off. Even the trusty Sharpie pen makes a big fat line.

But a scribe is perfect. It marks a clean sharp line. And better still, it cuts through 360 DTH hammer dirt, paint, rust, and mill scale. It's the tool to use for clean, accurate lines. Its secret Water Well Drilling is at the business end, a little sharpened rod of tungsten carbide, a material so hard it can even scribe a line on the surface of a tile. The Model 88 by General Tools is a particularly good example. Its durability is outstanding (you'll get years of use from it), and its tip is retractable (you can retract it so it doesn't poke a hole in your work shirt or coveralls).


As holds true with other things in life, when it comes to carbide scribes and metal working, little things mean a lot.
