When most people think of the metal manufacturing process, they imagine a stream of molten metal being poured into a mold—which makes for great visuals in movies and commercials. However, when you think about making parts from powdered metal, it can be a little hard to imagine the process, or why people bother with powdered metal in the first place.
The manufacturing method of metal powder is not necessarily simple, and there are only a handful of advanced powder metallurgy companies. Don’t worry – with proper explanation, the important concepts of the PM process are not difficult to understand.
Let’s look at the first steps of the powder metallurgy process – you’ll quickly understand how powder metallurgy differs from traditional machining.
Powder metallurgy process: what does it mean?
Is there any reason to specify powder metallurgy over conventional machining other than “that’s how we’ve always done it”? The answer is an unequivocal "yes" - and the reasons aren't just low cost.
In traditional manufacturing, you melt it, roll it, cast it, machine it. Lots of steps and a lot of scrap metal at the end.
Using powdered metal can significantly reduce waste and can therefore be called an environmentally friendly manufacturing process. It sounds contradictory, but it’s true!
Residual metal from machining is minimized. There are no metal fragments to throw away. If you look closely, you will find that powder metallurgy is indeed a "green process." In fact, a Ford Motor Company study a few years ago showed that the powder metallurgy process is 15 percent more energy efficient than traditional machining.
Of course, sometimes physical workpieces need to be machined. But for many projects, you can avoid secondary processing entirely by using a powder metal process.
What is powder metal? This is the metal "batter" from which we begin to form the metal "cake". Most importantly, it’s part of a sustainable process. To complete the cycle, products made from metal powders can be recycled and made into... new powders.
How metal powder is made？
Your manufacturer's powder metal supplier follows careful steps to produce a product that delivers the superior mechanical and/or magnetic properties your components require.
1. Select powder metal material.
When it comes to metal powders, you have several options. It is important to consult your powder metallurgy supplier first to obtain a mixture that supports the properties you need most.
Options include:
How Powder Metal is Made
iron
copper
brass
bronze
alloy steel
aluminum
zinc
tin
cadmium
lead
copper
chromium
magnesium
From there, you can choose from a variety of alloys (some come pre-mixed) to provide enhanced mechanical or magnetic properties. Iron or other ferrous metals are often popular in powder metallurgy due to their magnetic properties.
2. Make metal powder.
There are four main methods of making metal powder. Which method to use depends on a variety of factors, particularly the type of metal that needs to be powdered and the properties you prioritize.
Powder metal manufacturing methods include:
solid state reduction
atomization
electrolysis
Chemical
centrifugal atomization
Solid state reduction
Metal ore is crushed and then mixed with another material, usually carbon. After the mixing is complete, it is placed in a furnace to react, reducing the oxygen and carbon content in the powder.
The reduction in carbon and oxygen makes the metal mixture resemble a less appetizing sponge cake. The "sponge" is crushed and sieved to remove non-metallic materials. The final pellets are still spongy, which is a good thing - it means they compress well.
Solid state reduction is an ancient process but can take up to 3 days in a kiln to completely reduce iron ore to iron. It requires a relatively high purity of ore to obtain the desired end product.
Atomization
The process starts with scrap metal, which is then melted down. Once melted, a stream of metal is injected through a gas or water stream, causing the metal to break down. The goal is to break or atomize the metal into small droplets that solidify before coming into contact with the surface or each other.
Atomization is very effective for making metal powders and can be used with all types of molten metals. Commonly used for powdering:
iron
bronze
alloy steel
copper
brass
aluminum
zinc
cadmium
lead
Electrolysis
The electrolysis process requires specific conditions to be effective, including appropriate:
Electrolyte composition and concentration
density
temperature
As long as the right conditions are obtained, electrolysis can produce very pure and dense metal powders. Relative to other methods of making metal powders, electrolysis is expensive. It is mainly used on high value metals, especially copper, for applications requiring high electrical conductivity.
Chemical
The three main methods of chemical powder processing are:
Thermal decomposition
oxide reduction
Solution precipitation
These processes can produce metal powders with very specific qualities. For example, thermal decomposition is mainly used to process carbonyl compounds, while solution precipitation produces powders with high purity and narrow particle size distribution.
Centrifugal atomization
Another method of atomizing molten metal is to use a centrifuge, which consists of a porous container that separates the liquid metal into droplets of specific sizes. The speed of the machine can be changed depending on the desired result.
How are powder metal parts made?
Metal powder flows smoothly and can be formed into complex shapes – strong enough for the toughest components. By giving metals certain electromagnetic properties, we can create advanced motors and vehicles.
The manufacturing of powder metal parts is done through the powder metallurgy process. Here are the general steps for powder metal part manufacturing:
Raw material preparation:
First, a suitable metal material is selected, usually by mechanically or chemically preparing metal ingots or powder into metal powder with the required particle size. These powders are usually very fine and can be powders of iron, copper, aluminum, stainless steel and other metals.
Mixing and Recipe:
Metal powders are mixed with possible additives such as reinforcements, lubricants or other powder materials to achieve the desired chemical composition and properties.
forming:
Manufacturers use different molding methods to turn the mixture into the desired shape of the part. Common molding methods include compression, injection molding, and extrusion.
sintering:
The formed part undergoes a high-temperature sintering process, which fuses the powder particles together to form a strong part structure. Sintering temperature and time depend on metal type and product requirements.
Heat treatment (optional):
Sometimes powder metal parts are heat treated to improve the material's properties, such as increasing strength or hardness.
Post-processing:
After sintering is complete, the part may need to undergo machining, surface treatment or other post-processing processes to achieve the final size, shape and surface quality.
Testing and Quality Control:
Perform quality inspections on finished products to ensure parts meet design specifications and standards. This may include dimensional measurements, material testing and surface quality inspections, etc.
Packaging and delivery:
After completing all manufacturing and quality control steps, the powder metal parts are packaged and delivered as per the customer's requirements.
It is important to note that the manufacturing of powder metal parts can vary depending on the specific project and requirements. Different metals, shapes and performance requirements may require different processes and equipment. Manufacturers typically develop appropriate manufacturing processes based on customer needs and design specifications.
Tips for Choosing a Powder Metallurgy Company
Choosing the right powder metallurgy company is crucial to ensure the quality and performance of the components you need. Here are some tips to help you make an informed decision:
1. Reputation and Experience: Research the company's reputation in the industry. Look for established companies with a solid track record and extensive experience in powder metallurgy. A company with a long history of success is likely to have developed reliable processes and expertise.
