You think you have a car and see these amazing vehicles


What kind of bird is there in the woods? This sentence describes what people in the world have. The same is true of cars. The normal cars are cars, bicycles, rickshaws and trams. There are many things that are not normal, and it is impossible to imagine them. If you do not look at them with wheels, you can't really tell what they are. Do not say, look at the map.

You think you have a car and see these amazing vehicles

This, you are sure that this is not to remove the fitness equipment at your door?

One person who wants to ride this car is estimated enough!

You are gymnasts, buddy!

You think you have a car and see these amazing vehicles

The amount... This is still a normal point. At least it can be seen that it is a walking tractor.

But what is the ghost of this TM Buick Landmark and Audi A6L?

This thing actually has a license plate!

Judging from the license plate, this uncle you are lucky (surname) blessing it ...

Visually measuring the price of this brand is not cheap

Oh! This big guy is arrogant ~

It’s been a few years since I was watching photos, even if it’s still a rare thing

Visually, this is the wheel of the tractor, even with a leather seat

With the red flag, go directly to the military parade

This ... motorcycles are also lengthened?


Pulling Black Live must earn a lot


Back to this tool!


I have seen lying in the car, it is a common type of bicycle in foreign countries.

But this lying car is absolutely!

This seat also has pillows as cushions. Hand brake

Big Brother, are you sure that this is not a wheelchair change? ?

The most luxurious carriage.....

Look at the body should be the Russian production of the Rada 2105, this car in the 80-90 years in the domestic active for some time

The Lada 2105 is 4140mm long, 1630mm wide, 1450mm high, and the wheelbase is 2430mm. Use front drive drive mode.

It also launched the taxi market and was later replaced by a better-quality joint venture vehicle.

To this end, Lada also gradually introduced the Chinese market. ?

Are you sure this is not PS? Siamese children?


This change of face reminds me of it

This is not what the two Jeep Wrangler Rubicon got together...

Human wisdom is endless


Can't afford trains, scrap trucks come to Minato


This hub does not violate the special rails


The best dog for working dogs


Things can be done on the road


Amount, I'm sorry everyone put this picture


This is definitely a natural speaker


With it it is estimated that people should observe traffic


Finally, I would like to silently ask... buddies! Is it painful?


This car is high and I have seen it in my childhood

The wheels of the animated cartoon "Tiejia Xiaobao"


I never wanted to ask


Do you have any childhood?


Finally, I want to move out of my ultimate car


Seoul and other citizens can retreat!



"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.
