The danger of excessive maintenance of the car
Usually, the car owner will give the car a maintenance plan after buying the car. Some of them will go to the 4S shop for direct maintenance. When the time comes, someone will remind you to do the maintenance. There is also the maintenance from the merchants, usually the first time for free, and then start collecting money from the second time, the longer the car is used, the more the store recommends that you maintain more content, the faster the time. This seems to be no problem, but if the car doesn't take long, I suggest you do a lot of maintenance in the store, saying that it is good for your car, will you be tempted? Today, Xiaobian will tell you about the dangers of over-maintenance of cars . Beimai Auto Parts Xiaobian first said to everyone from the usual car wash we usually do, generally speaking, car wash everyone do not understand, I think car wash is good for the car, and everyone knows that the static electricity on the car is easy to absorb dust, also There will be rain stains when it rains. These long-term corrosion of car paint on the car, car wash is obviously to protect the car, but frequent car wash, car wash will have to clean the car, then the car will be thinner. Ultraviolet radiation will make the car paint age faster, plus the car wash liquid must be used when washing the car. This acid and alkali sometimes does not pay attention when you buy it. If it is too acidic and alkaline, it will corrode. Bodywork. Generally, washing a car for ten days or two weeks is actually a matter of saving money and effort. You don't have to spend time every week to wash. Everyone knows the importance of the engine to the car. The general engine cleaning agent can clean the engine's carbon deposits, oil stains, etc., so it is not very clear how long the engine is cleaned. Generally, when cleaning the engine, it is cleaned once in a maintenance cycle. Without excessive cleaning, the carbon deposit will not be so fast. Of course, it is also necessary to keep a good habit of driving. It is not possible to drive at an idle speed and brake suddenly. These behaviors are likely to cause carbon deposition. Cleaning the engine also depends on the mileage traveled. There are also maintenance systems for the brake system. Vehicles under 40,000 km do not need to be maintenance-maintained for the brake system. Fuels and oil additives that enhance power and reduce fuel consumption are generally exaggerated in the propaganda function, but they are not good for the engine, but will intensify the wear of the engine and cause the vehicle exhaust to fail. These can not be used as much as possible, even if you want to use the quality, you can also consult the manufacturer, this additive is not suitable for this car. If you have already used the oil additive, please change the oil immediately. The fuel additive should also use the manufacturer's certified product. In fact, detergents have been added to the fuel sold in most domestic petrol stations. The danger of over-maintenance of the car is finished for everyone. Everyone knows that parents can't usually bring their children now, because parents love their children too much, which is not good for the child's body and mind. But if the car is over-maintenance, is it also a principle? Excessive maintenance of the car can also cause injury. In fact, this is not difficult to understand, because there are many chemicals in the car when it is used for maintenance, and these chemicals are used more. If the time is long, the paint will corrode. The damage said is inevitable. So it is important to develop a maintenance watch. I hope that the small series of articles will be useful to everyone.
The domestic current
situation of the die-casting mould
Die Casting Mould industry
has developed rapidly in our country, the total output growth significantly,
domestic die casting mold production after the United States, has become the
second in the world, become the veritable die-casting superpower. It can have
such achievement because of our country with unique broad market advantages and
relatively cheap labor force. Depend on very obvious price in the international
trade market, we produced the die casting mould which occupies a bigger
superiority, according to the situation, in the future Chinese die casting
industry development prospects are very broad.

What is the Moldflow analysis, this conception
derived fromtaiwan.
it's a precess through the computer for injection molding simulation by data
simulate software, and get data result. Then assess the feasibilty of the mold
program through these results to perfect mold and production designation.The
common software for plastic mold such as moldflow, moldex 3D and so on. And the
common software for Aluminum Die Casting Parts such as PROCAST, FLOW 3D and so
on.

1, According to the materials, shape and precision product, analyze technology,
decide of the process.
2, Confirm the location of product in the mold cavity. Analyze parting surface,
overflow system and the gating system.
3, Design the various activities of the core are assembled and fixed method.
4, Design the core-pulling distance and force.
5, Design the ejection device.
6, Confirm the die casting machine, design the mould base and the cooling
system.
7, Checking the mould size and die casting machine, drawing the process
flowchart and component of die casting mold.
8, Design is complete.
