Recently, the second batch of 13 55T Kato crane chassis trucks opened the doors of the FAW Liberation Chief Special Branch Company in the morning, and took Changte Branch to realize the dream of overseas strategy, took over their own confidence, and resolved to overcome the crisis. As it heads for the port of Dalian, it will soon arrive in Japan. At this point, the FAW-Jielong Special Branch Company has cumulatively exported 25 Japanese 55T Kato crane chassis trucks, and the remaining 16 vehicles will be sent to Japan by time. This indicates that the Liberation Chief Special Branch Company has made a big progress in the overseas market and is also the result of the Party's mass line education practice.


In order to realize the goal of “Challenge 13, Climb 14 and Cross 15”, the Liberation Chief Special Branch Company has taken the development of overseas markets at the beginning of the new year as a breakthrough for this year’s incremental efficiency increase, and has detailed plans for overseas development. It has been 3 years since the joint venture company of the Liberation Chief and the Japanese company Kato had been developing the crane vehicle. This year, Kato Corporation of Japan and the Special Branch of the Liberation Chief signed purchase orders for 41 chassis crane 55T cranes.

For the early delivery of the 45 55T crane chassis to the Japanese side, the leader of the special branch of the Liberation Chief requested the members of the Kato project team to reflect the spirit of the party’s mass education and practice activities during the completion of the project, and to carefully find out what happened in the assembly. The problems were discovered in a timely manner, resolved quickly, carefully organized, carefully assembled, and carefully examined, never letting a glimpse of flaws, leaving the Japanese factory personnel to feel our work attitude and thorough service quality. The members of the Kato project team also devoted themselves to the rigorous assembly with active, serious and strict working spirit. Under the leadership of deputy chief engineer Sun Yongjun, they fought with high temperature and intense heat, and completed the steering and tilting of the ball head and turn. More than a dozen technology research tasks, such as power cylinders and expansion tanks, have made a qualitative leap in the quality of the vehicle and have met the Japanese quality acceptance criteria. They have been fully affirmed and highly praised by Japanese personnel at the plant. The first batch of 12 55T crane chassis trucks were handed over to Japanese users in mid-July and will be sent in September.

The export of 41 55T crane chassis trucks will realize a sales income of 8.17 million yuan, which will help the company to achieve incremental efficiency gains.

In addition, the FAW Jiefang Chang Special Branch Company has successively negotiated and negotiated business relationships with car dealers in Georgia, Russia, and South Africa, which has enabled the development and expansion of overseas markets.

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.
