It is very scary to find out the cause of the failure


Car extinguishing causes:

1, automatic transmission models will not easily turn off the phenomenon, and manual file models due to low driving level, may often turn off the phenomenon. However, it is not ruled out that the stalls of automatic transmissions will not be extinguished. The main reason is the use of inferior fuel oil (many gas stations have to sell off impure oil to obtain profit) and cause the engine to deposit carbon.

2. In addition, the reason for the stalling of the new car (automatic file) is mainly due to the lack of driving skill. Another possibility is the problem of the car engine or the oil circuit. However, for the new car, the engine itself is more likely to have problems. Small, most of the reason is the problem of the oil circuit.

3, Finally, for the old models, the reason for the flameout is that, besides driving techniques, it is not enough to use the oil that causes the engine to collect carbon.

Auto gear stalling troubleshooting methods:

Usually pay attention to the place: For the phenomenon of automatic stalling the car, mainly due to the use of poor fuel. One is to increase the marking oil to a regular larger gas station, such as the use of gasoline No. 95, although the price is a lot more expensive, but it can guarantee the longer life of the car and a good driving force. However, some owners are eager to add the No. 92 oil, although the price is lower, but problems may arise in the future. The second is to go to a large qualified gas station to refuel!

Actual operation: Hold the steering wheel firmly with your left hand (because there is no power, so be sure to hold it firmly). Use your right foot to apply the brakes to reduce the speed as quickly as possible, then quickly transfer the AT file to the N position. (Note: Replay in progress. The fire must be in the N range, not the D/R/P, etc. Otherwise, the car will either fail to fire or the car gearbox will be damaged), then it will retreat the key, then re-ignite the fire, and then the AT file again The bit resumes normal driving to D.

Manual gear stalling troubleshooting methods:

1, for the novice, half-way flameout is not a new topic, the main exclusion method to quickly improve after driving skills.

2, the use of high quality and qualified fuel.

3, a thorough cleaning of the oil, including injectors, throttle, fuel tanks and so on. It may be because of the quality of the oil you add, but too much rubber, blocking the oil path, and causing poor oil attack.

4. The main reason for the failure of the car when the car is idle is due to excessive dust in the air. When the engine is running, there are many fouling deposits on the idler valve and the throttle seat. When the dirt accumulates too much, the engine will idle. Low, low idle stability, idling stop when driving. The solution to this problem is simple: just clean the idle motor.

5, whether the oil road is open, it also easily lead to half-way off.

6. Long-term parking is not used. In fact, avoid parking for a long time. If the parking time is long, you should do a thorough maintenance before replacing it, change the oil, machine filter, etc., and check the fuel, circuit, etc., as appropriate. Your vehicle may have caused lubrication or circuit problems because of long-term parking.



Gravity Casting Parts

"Gravity Die Casting. A permanent mould casting process, where the molten metal is poured from a vessle of ladle into the mould, and cavity fills with no force other than gravity, in a similar manner to the production of sand castings, although filling cn be controlled by tilting the die."

Gravity Die Casting

Sometimes referred to as Permanent Mould, GDC is a repeatable casting process used for non-ferrous alloy parts, typically aluminium, Zinc and Copper Base alloys.

The process differs from HPDC in that Gravity- rather than high pressure- is used to fill the mould with the liquid alloy.

GDC is suited to medium to high volumes products and typically parts are of a heavier sections than HPDC, but thinner sections than sand casting.

There are three key stages in the process.

  1. The heated mould [Die or Tool] is coated with a die release agent. The release agent spray also has a secondary function in that it aids cooling of the mould face after the previous part has been removed from the die.
  2. Molten metal is poured into channels in the tool to allow the material to fill all the extremities of the mould cavity. The metal is either hand poured using steel ladles or dosed using mechanical methods. Typically, there is a mould [down sprue" that allows the alloy to enter the mould cavity from the lower part of the die, reducing the formation of turbulence and subsequent porosity and inclusions in the finished part.
  3. Once the part has cooled sufficiently, the die is opened, either manually or utilising mechanical methods.

Advantages

  • Good dimensional accuracy
  • Smoother cast surface finish than sand casting
  • Improved mechanical properties compared to sand casting
  • Thinner walls can be cast compared to sand casting
  • Reverse draft internal pockets and forms can be cast in using preformed sand core inserts
  • Steel pins and inserts can be cast in to the part
  • Faster production times compared to other processes.
  • Once the tolling is proven, the product quality is very repeatable.
  • Outsourced Tooling setup costs can be lower than sand casting.
