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 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 ...

Difference between casting flange and forging flange

2024-09-03

Casting flange Casting flange, blank shape and size accuracy, small processing, low cost, but there are casting defects (porosity. Cracks. Inclusions); casting internal organization streamline is poor (if it is cutting parts, streamline is poor); forging flange is generally lower than casting flange, low carbon content, not easy to rust. Forging streamline good, dense organization, mechanical properties better than casting flange; if the forging process is not appropriate, the grain will be large or uneven, there will be hardening cracks, forging cost is higher than casting flange. Forgings can withstand higher shear and tensile forces than castings. The advantages of castings are complex shape and low cost; uniform internal organization, no casting holes, inclusions and other harmful defects; casting flanges and forging flanges, such as centrifugal flanges, belong to one of the casting flanges. Centrifugal flange is a precision casting...

Aluminum die casting mold design and manufacturing

I. The purpose of developing standards 1. Reduce downtime caused by molds, production stoppages, improve labor productivity, reduce manufacturing costs. 2. Promote mold manufacturers to improve the level of mold manufacturing and quality, reduce its after-sales...

Aluminum die casting mold structure

2024-08-05

A, die casting mold foundation 1.die casting concept die casting: refers to the high temperature molten metal liquid in the state of high speed and high pressure under certain conditions to quickly fill the cavity, and in a certain pressure under the action of rapid cooling of the molding process. Die casting mold is an important process equipment in die casting production, it is extremely important to the production can be carried out smoothly, the quality of the castings play an extremely important role, it and die casting production process, production operation exists and mutual influence and mutual constraints, close relationship. Die casting mold determines the casting shape and size tolerance level; Its pouring system determines the molten metal filling condition; In the production process, control and regulation of die casting process heat balance; The strength of the mold limits the maximum limit of the pressure of the ejection ratio, affecting the production efficiency of die casting production. 2. The structure of die casting mold die casting mold is mainly by the fixed mold and moving mold...

Aluminum Die Casting Mold

Aluminum die casting die refers to the tool used to manufacture aluminum alloy high die casting, usually by the die kernel, die seat, die core, cooling device, sliding device, ejector device and other components. The following is a detailed analysis of aluminum die casting die: a, classification aluminum die casting die and die casting machine can be divided into: Horizontal cold room die casting die: die casting machine die for horizontal placement of die casting room, direct contact with molten aluminum water. Horizontal hot chamber die casting mold: die casting machine mold for horizontal placement of die casting room and molten aluminum water separation. Vertical die casting machine mold: die casting machine mold for equipment standing, up and down the mold. Second, the principle of work in the die casting production process, die casting mold installed in the die casting machine, and die casting machine to form a whole. Through the pressure of the die casting machine, the metal liquid in high pressure, high speed filling the mold cavity, in the high pressure under the cold...

Aluminum oil sump

2024-08-05

What is an oil pan? The oil pan is located in the lower part of the engine's crankcase, also known as the lower crankcase. Used to seal the crankcase, collect the engine friction generated by the lubricating oil back to prevent outside dust impurities into the lubricating oil. Classification of the oil pan: common have these kinds of oil pan Plastic oil pan Plastic oil pan refers to the oil pan material for engineering plastics, using plastic injection mold processing technology manufacturing, this material is manufactured by the oil pan more thin and lightweight, design freedom is relatively high, relatively inexpensive, more convenient installation. Has a certain degree of toughness. However, the high temperature resistance and corrosion resistance of plastic oil pan is relatively poor, the life is relatively short, suitable for low working temperature, low frequency of use, the weight requirements of the environment. Aluminum alloy oil pan Aluminum alloy oil pan due to the use of aluminum...

High pressure casting Die casting machine tonnage selection

2024-08-03

These days a customer asked me how to choose the right die casting tonnage is not die casting tonnage the bigger the better, so write this article slightly explain the die casting mold tonnage selection. Picture high pressure casting is a kind of pressure casting, in the case of high speed and high pressure liquid through the pressure chamber, by the die casting machine hammer into the mold internal molding, die casting machine tonnage the larger the pressure is mainly reflected in the clamping force, and die casting hammer. So how to judge the die casting products need the size of the tonnage? How to calculate the high pressure die casting tonnage, here we mainly from four aspects to consider: 1, calibration die casting products clamping force What is clamping force? Clamping force refers to, high pressure die casting products in the casting process, the molten metal liquid with high pressure into the mold cavity will produce a hold up the force, this time high pressure die casting machine exerted to the mold of...
