What is the gravity casting process锛?/span>
How does the gravity casting process work?
1. Gravity casting is one of the first processes invented for die casting of metals and light alloys. In this process, which can be fully automated, molten metal is poured directly from the dumpling into semi-permanent or permanent molds. The goal is to fill the mold with minimal turbulence through one or more channels, reducing oxidation and blistering. This minimizes porosity and inclusions, providing optimum metal properties in the final casting. Gravity casting equipment can have vertical or horizontal mould openings or tilt technology with 0/90掳 or 0/120掳 inclination to provide alternatives. With tilt die casting, the flow of metal at the die inlet is controlled by the tilt angle and speed of the die.
Advantages of inclined gravity casting.
An advantage of inclined gravity casting is that it produces dense, high-quality castings with excellent mechanical properties such as strength and stiffness. This makes it ideal for demanding automotive applications such as braking systems and suspension components.
The main advantages of gravity casting technology include:
1. Suitable for high-volume, automated production.
2. Minimum investment required for small and medium batch production.
3. Produces parts with excellent mechanical properties suitable for heat treatment.
Gravity casting can also produce parts with complex shapes since the sand core can be placed inside the mold.
Principle and characteristics of gravity casting.
Gravity casting refers to the process in which molten metal is injected into the mold under the action of the earth’s gravity, also known as gravity casting. The generalized gravity casting includes sand casting, metal casting, investment casting, lost foam casting, mud casting, etc.; the narrow gravity casting mainly refers to metal casting.
1. There are many process methods for making metal materials into desired products, such as casting, forging, extrusion, rolling, drawing, stamping, cutting, powder metallurgy, and so on. Among them, casting is the most basic and commonly used process.
2. The molten metal is injected into a hollow mold made of high-temperature resistant materials, and after condensation, a product of the desired shape is obtained, which is casting. The resulting product is casting.
3. Casting can be divided into ferrous metal casting (including cast iron, and cast steel) and non-ferrous metal casting (including aluminum alloy, copper alloy, zinc alloy, magnesium alloy, etc.) according to the material of the casting. The precision casting factory specializes in non-ferrous metal casting, with an emphasis on aluminum and zinc alloy casting.
4. Casting can be divided into sand casting and metal casting according to the material of the casting mold. The precision casting factory is handy with both casting processes and designs and manufactures these two types of casting molds by themselves.
5. Casting can also be divided into gravity casting and pressure casting according to the casting process of molten metal. Gravity casting refers to a process in which molten metal is injected into a mold under the action of the earth’s gravity, also known as casting. Gravity casting in a broad sense includes sand casting, metal casting, investment casting, lost foam casting, mud casting, etc.; gravity casting in a narrow sense refers to metal casting. Die casting refers to a process in which molten metal is injected into a mold under the action of other external forces (excluding gravity). Die casting in a broad sense includes pressure casting and vacuum casting of die casting machines, low-pressure casting, centrifugal casting, etc.; pressure casting in a narrow sense refers to metal die casting of die casting machines, referred to as die casting. The precision casting factory has long been engaged in the gravity casting of sand and metal molds. These casting processes are the most commonly used in non-ferrous metal casting at present, and they are also relatively cheap.
Application of precision investment casting process.
Gravity casting technology is ideal for the production of various complex aluminum castings for automotive parts such as turbochargers, brake calipers, steering knuckles, engine cylinder heads, engine blocks, and pistons. It is also suitable for many other industries from lighting components to kitchen tools.
What are the advantages of gravity casting molds?
1. What is a mold? Molds, various molds, and tools are used in industrial production to obtain the desired products by injection molding blow molding, extrusion, die casting or forging, smelting, stamping, and other methods. Under the action of external force, the blank becomes a tool with a certain shape and size. It is widely used in blanking, die forging, cold heading, extrusion, powder metallurgy parts pressing, pressure casting, and compression molding or injection molding of engineering plastics, rubber, ceramics, and other products. The mold has a certain contour or cavity shape, and the use of the contour shape with the cutting edge can separate the blank according to the contour shape (blanking). Applying the cavity shape allows the blank to obtain a corresponding three-dimensional shape. The mold generally includes two parts, a movable mold and a fixed mold (or a punch and a concave mold), which can be divided and combined. When separated, the parts are taken out, and when closed, the blanks are injected into the mold cavity to form. The mold is a precision tool with a complex shape, which bears the expansion force of the blank, and has high requirements on structural strength, rigidity, surface hardness, surface roughness, and machining accuracy. The development level of mold production is an important symbol of the level of machinery manufacturing.
2. Classification of molds. The different materials to be formed, it is divided into metal molds, plastic molds, and other special molds. Hardware dies are divided into: including stamping dies (such as blanking dies, bending dies, deep drawing dies, turning dies, shrinkage dies, undulating dies, bulging dies, shaping dies, etc.), forging dies (such as die forging dies, upsetting dies, etc.) forging dies, etc.), extrusion dies, extrusion dies, die-casting dies, forging dies, etc.; Non-metallic molds are divided into plastic molds and inorganic non-metallic molds. According to the different materials of the mold itself, the mold can be divided into a sand mold, metal mold, vacuum mold, paraffin mold, and so on. Among them, with the rapid development of polymer plastics, plastic molds are closely related to people’s lives. Plastic molds can be generally divided into injection molding molds, extrusion molding molds, gas-assisted molding molds, and so on.
3. What is Gravity Casting Mould. Gravity casting mold refers to the process of injecting molten metal into the mold under the action of the earth’s gravity, also known as casting mold. Gravity casting in a broad sense includes sand casting, metal casting, investment casting, mud casting, etc.; gravity casting in a narrow sense refers to metal casting. As an indispensable part of the gravity casting process, the application of gravity casting molds is a more frequent mechanical equipment.
4. What are the advantages of gravity casting molds?
(1). When casting, the metal liquid is subjected to high pressure and a fast flow rate.
(2). The product has good quality, stable size, and good interchangeability.
(3). The mold life is longer than that of die casting, and the mold cost is low.
(4). The process is relatively simple.
