On February 6, 2015, the Delta Group's 2014 work summary awards and 2015 work deployment meeting was held. Last year, the group built a global marketing network and its sales network has covered more than 170 countries and regions.
In 2014, the Triangle Group adapted to the “new normal†of the economy and, under the guidance of the Global Development Strategy, accelerated the enhancement of the international competitiveness of manufacturing, technology, marketing and management, and continued to maintain its leading position in the industry. Up to now, Delta has received a total of 321 patents, including 42 invention patents and 24 international patents, ranking first in the domestic industry. The 2014 triangle represents the tire industry's 2nd participation in the UN/WP29GRRF meeting of the United Nations World Vehicle Regulatory Forum's Coordination Meeting (UN/WP29GRRF) and is directly involved in the global tire technical regulations coordination process.
On the same day, Ding Yuhua, chairman of the Triangle Group, delivered a speech calling on the company to continue to take the road of globalization. In 2014, Delta Group accelerated the construction of a global innovation system and established a global marketing network. The current sales network has covered more than 170 countries and regions, forming a regional business system in North America, Central and South America, Europe, Asia Pacific, Middle East and Africa. Last year The market in Central and South America, the Middle East, Asia Pacific and Europe increased by 6%, 12%, 7% and 3% respectively year-on-year.
It is reported that in recent years, the company has always focused on building new productivity models and accelerating the pace of transformation and upgrading. The Lingang District and Nanhai New District projects were launched in 2014. The two projects use an advanced team for factory design, and more than 90% of the equipment comes from international advanced manufacturers. They use advanced automation, digital identification, and robotics to build intelligent smart factories. .
When it comes to work arrangements for 2015, Ding Yuhua said that 2015 is the year of the end of the Twelfth Five-Year Plan for the National Economy, and it is also a crucial year for the future development of the company. “The company will grasp the development characteristics of the new industrialization and seriously establish globalization. The concept of 'marketing people', seriously developing and using global talent resources and market resources, accelerating the construction of new manufacturing models, new business models, and new management models, and unwaveringly promoting the development of the company's globalization to a new level."
"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.
- 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.
- 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.
- 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.
