Recently, Xugong successfully exported 200 dump trucks in Central Asia, and once again achieved large quantities of products exported to Central Asia. In recent years, the Central Asian market has established a complete dealer network and service spare parts system under the efforts of XCMG Import & Export Corporation. It has strengthened the support for agents in service spare parts, and has maintained and gradually expanded the sales of core competitive products.

XCMG Heavy Duty Card continuously strengthens its technical support to agents. Each agent sets up a technical service support department, engineers with various products, and establishes a service hotline to enable users to obtain the answers to relevant product technical and service questions and claims at the first time. The timely processing.

At the same time, the technicians assigned by XCMG and customers jointly develop products that are more suitable for the local market, and work together with distributors to promote the XCMG brand and make good use of exhibitions, newspapers, television, and other media to promote the XCMG brand. , support agents to participate in the local influential large-scale mechanical professional exhibition.

At the same time, the dispatch of elite personnel will advance the position, serve the customers, and timely feedback the relevant market needs to the company so as to serve the market quickly and efficiently.

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.
