Casting Parts:
The casting is a metal human control of hot working
process relatively early, has a history of about 6000 years.In early 1700 BC to
1000 China has entered into casting heyday era,the technology has reached a
very high level.
the material to be casting is usually solid
but heated to a liquid metal (copper, iron, aluminum, lead, tin, etc.), and
mold materials can be sand, metal and even ceramics. In response to different
requirements, the use of the method will be different.

Category:
Casting blank is almost forming, which
achieves the goal of free machining or less processing, reduces cost and
reduces production time to a certain extent. Casting is one of the basic
processes in modern equipment manufacturing industry.
(1) Sand casting:
Using sand as the mold material, also known
as sand casting, foundry, including wet sand, dry sand and chemical hardening
sand 3, but not all are available in sand casting. Advantage is low cost,
because of the use of the mold sand can be reused; drawback is the mold
manufacture time-consuming, repeated use casting model is not possible. To
damage can be achieved after the finished product.
(2) Special Casting Process:
According to the special casting molding
materials can be divided into natural mineral sand as the main materials (such
as casting, mud casting, shell casting, vacuum casting, mold casting, ceramic
mold casting, special casting and metal) as the main cast materials (such as
metal casting, pressure die casting, continuous casting, low pressure casting,
centrifugal casting, etc.
2.1 Metal mold casting method: using high
melting point is the raw material made of metal mold. The subdivision for
gravity casting, low pressure casting and pressure casting method. By casting
the melting point can be cast metal has also been limited.
2.2 Lost wax casting method: this method
can for membrane casting and solid casting. First the object copy the required
casting wax, and then dipped into ceramic containing (or silica sol) in the
pool and stay dry, the wax replica covered with a layer of ceramic membrane,
repeating the steps until the outer membrane is sufficient to support the
casting process (about 1/4 inch 1/8 inch), wax melting in the mold, and out of
the mould. Then many times to enhance the mold temperature, the hardness can be
used to rear casting.
Based on different casting raw material,we`ve
Steel Die Casting,copper alloy die casting and aluminium alloy die casting.
Processing:
(1)The mold preparation (liquid metal become
a solid container for casting ) according to the material used can be divided
into sand, metal, ceramic, clay, graphite, according to the frequency of use
can be divided into single type, semi permanent and permanent mold preparation,
quality is the main factor affecting the quality of castings;
(2) The melting and casting;:casting metal
(alloy) mainly include all kinds of cast iron, cast steel and casting of
nonferrous metal and alloy castings;
(3) The processing and inspection: casting
processing including removal of the core and the casting surface removal of
foreign body, riser, shovel thorn and sanding fash protrusions and heat
treatment, plastic. Anti rust and rough machining.

Dongfeng Group Co., Ltd. denied the merger with FAW Group and announced that it has not introduced a plan for a new joint venture brand.
On March 29th, at the 2016 performance conference held in Hong Kong, Dongfeng Motor (6.700, 0.03, 0.45%) Chairman Yan Yanfeng made it clear that the cooperation between Dongfeng and FAW is mainly to jointly research forward-looking technology and discuss other issues in the market. The question "No discussion, no plan".
The market generally understood that the speech of Yan Fengfeng pointed to the merger rumors of Dongfeng Motor and FAW which had long been circulating.
On March 30, Dongfeng Motor’s listed company Dongfeng Motor Group Co., Ltd. (Dongfeng Group Co., Ltd., 00489.HK) told the relevant sources that Mr. Yan Yanfeng did have related statements. As of now, the Group has not merged with FAW Group. Plans and arrangements. However, it also added that, after all, the merger of the two major central SOEs will be able to accurately know the dynamics and details will be very few, but there is no relevant news at the public level.
On February 17th, Dongfeng Motor Corporation and China FAW Group Co., Ltd. jointly established the signing ceremony of the “Forward-looking and Common Technology Innovation Center†strategic cooperation framework agreement in Changchun. According to the news of Dongfeng Group Corporation, according to the agreement, according to the agreement, Dongfeng and FAW will jointly explore new systems and mechanisms for technological innovation management on the platform of the Innovation Center, share technical and investment risks, and reduce R&D costs. Rapidly improve the research level of forward-looking common technologies in the Chinese automotive industry.
In the 2016 annual report, Dongfeng Group's shares will clearly focus on the development of new energy batteries, motors, and electronic control technologies, and accelerate the deployment of intelligent networking business as the Group's key work in 2017.
The annual report shows that in 2016, Dongfeng Group's auto sales vehicles exceeded 3 million units, reaching 3.5168 million units, up 10.1% year-on-year; sales volume ranked second in the industry; profit attributable to shareholders amounted to approximately 13.355 billion yuan, up year-on-year.
