What is high pressure die casting? High pressure casting principle: high pressure die casting (HPDC) refers to a production of metal products casting process, the principle of the process is to melt the metal solution at high temperature through the hopper will be melted metal liquid poured into the die casting machine injection pipeline, in the piston or plunger in the hydraulic pressure or pressurized gas push forward. Make the melted metal liquid filled die casting mold cavity, under the action of pressure forming and solidification and obtain castings, then die casting machine in the role of the cylinder to open the high-pressure die casting mold, aluminum die casting parts out, this process is called high-pressure die casting. As shown in the following diagram die casting machine production moving picture: high pressure die casting process characteristics of high pressure die casting advantages and disadvantages: high pressure die casting advantages: 1, casting high dimensional accuracy, surface finish is good, generally equivalent to 5 ~ 8. 2, high strength and hardness ...

Aluminum alloy processing technology

Aluminum is the most widely used and widely applied metallic material among non-ferrous metals, and its applications are still expanding. Aluminum produces an endless variety of aluminum products. According to statistics, there are more than 700,000 kinds, from the building decoration industry to the transportation industry, aerospace and other industries have different needs. Today, I will introduce the processing of aluminum products and how to avoid processing deformation. The advantages and characteristics of aluminum are as follows: Aluminum products processing technology Aluminum products punching 1, cold punching Use of materials aluminum particles. The extruder and die are used for one-time molding, which is suitable for oval, square, rectangular products and other column-shaped products or product shapes that are difficult to achieve by stretching process. (Such as Figure 1, Figure 2, Figure 3 products) The tonnage of the platform used is related to the cross-sectional area of the product. The gap between the upper die punch and the lower die tungsten for the product...

Sand casting process

2024-10-08

What is sand casting? Sand casting, also known as sand casting, is a time-honored method of casting process with a wide range of applications across the globe. It is a process method of producing castings by using clay-bonded sand (or sand molds made of other materials such as gypsum and silicone resin) as the molding material. The principle is to take advantage of the softness and ease of molding of the sand mold by pouring molten metal into the sand mold, and then crushing the sand mold after the metal has solidified in order to obtain the desired casting. Applied in a variety of metals, common aluminum sand casting, iron sand casting, copper sand casting, now let the aluminum alloy casting factory located in China Ningbo He Xin for everyone to explain the sand casting process. Conventional process flow of sand casting production Sand casting process (1) Preparation of molding sand and core sand The molding material for sand casting is mainly used for...

Mold flow CAE (fluid simulation technology) casting applications

2024-10-08

Nowadays, with the development of computer software, artificial intelligence, simulation and analysis software accuracy and credibility, mold flow analysis software in the casting industry is more and more common. cae simulation technology is widely used in the development of casting molds and product production. Today, I will introduce the widely used in the industry software magma, flow3d, procast, anycasting, China casting CAE, the other have novcast, jscast. more professional simulation soft or: anysys , star ccm wait for software, this kind of software is more complex, mainly for automobile, aircraft, ship simulation. Basic Principle CAE (Computer Aided Engineering) is based on the basic principles of fluid mechanics and solves the equations of motion of fluids by numerical methods, thus simulating the flow state of fluids. These equations usually include mass conservation equations,...

Aluminum alloy gravity casting, high-pressure casting, low-pressure casting process introduction awareness

2024-09-04

Gravity casting introduction: gravity casting refers to the aluminum liquid in the earth's gravity under the action of gravity injection casting process. Broad gravity casting gravity casting is divided into sand casting, metal type (steel mold) casting, disappearing mold casting. ; Narrow gravity casting refers to the metal type casting. Metal casting is divided into upright hand casting, tilted casting is now most commonly used metal mold (steel mold) casting. The mold is made of heat-resistant alloy steel, casting aluminum castings strength, size, appearance are higher than other casting processes. Aluminum liquid for gravity casting is generally poured manually into the gate, relying on the self-weight of the metal liquid to fill the cavity, exhaust, cool, and open the mold to obtain the sample. The process flow is generally as follows: aluminum liquid melting, pouring, exhausting, cooling, mold opening, cleaning, heat treatment, processing. -Ningbo Hexin Aluminum alloy gravity castings are ...

Semi-solid metal casting process

2024-08-03

1, Overview Since 1971, the Massachusetts Institute of Technology's D.B. Spencer and M.C. Flemings invented a stir casting (stir cast) a new process, that is, the use of rotating double barrel mechanical stirring method to prepare a Sr15% Pb rheological slurry since the semi-solid metal (SSM) casting process technology has experienced more than 20 years of research and development. The alloys prepared by stir casting are generally known as non-dendritic organization alloys or called Partially Solidified Casting Alloys (Partially Solidified Casting Alloys). Products using this technology have a strong vitality due to their high quality, high performance and high alloying characteristics. In addition to applications in military equipment, it has begun to focus mainly on key components for automobiles, for example, for automobile wheels, which can improve performance, reduce weight, and lower scrap rates. This ...

Classification of metal manufacturing processes

Hot working includes casting, forging and welding. Cold working, also known as metal cutting process, including tool cutting process (which has turning process, drilling and boring process, planing, inserting, broaching, milling process, abrasive cutting process; the processing of gear teeth). The following are briefly introduced. (A) casting The casting process is to pour liquid metal into the mold, to be cooled to obtain a certain shape and sex of the casting. This is the method of molding metal in the liquid state. Casting can produce billet blanks of complex shapes, especially complex internal cavities, with unlimited size and weight. Both single-piece production, can also be mass production, the use of most of the material from a wide range of sources, low prices, but also available scrap and waste parts, so the cost is low. Castings and parts of the shape and size close to the processing allowance is small. Casting...
