How the Powder Production Line is Used to Produce Car Parts That Will Last

The Powder Production Line process is used to produce parts that will last. This includes car parts that must be able to withstand high wear and tear. These parts must also have exceptional dimensional tolerances to last.

There are four basic steps in the Powder Production Line process: powder preparation, blending and agglomeration, injection molding and isostatic pressing, and sintering.

The Process

The physical checks that are performed on products as they undergo manufacturing have to match the dimensional requirements set out for them. This is especially true for parts that are installed in cars, planes or machinery, where they need to last a long time so that the cost of replacement or repairs can be minimized. It is also important that they have good wear resistance and friction coefficients to prevent them from deteriorating over time, which can lead to the need for frequent replacement or repairs.

Powder metallurgy allows for net-shape manufacturing of parts from materials that can be difficult to manufacture via the classical ingot metallurgy route. Examples of such materials include the WC-Co hard metal with its peculiar microstructure, as well as parts with special magnetic properties.

Consequently, PM processes have typically been viewed as stochastic and non-linear and therefore challenging to control. As a result, they have been subject to substantial research and innovation on PSD estimation methods in order to provide an accurate real-time measurement of the physical state of the powder mixture.

Given this, the goal of this paper is to apply concepts of cybernetics towards the development of self-regulating machinery for a PM process that can take mitigating action when its state deviates from production standards. This is achieved by using the AE sensor to provide a real-time estimation of the PSD of the in-process powder mixture and then feeding this information into a control algorithm that can be used to optimize the manufacturing process in real time.

Raw Materials

The building blocks of matter have fuelled the imagination of philosophers, scientists and artists for millennia. But for manufacturers, these elements Powder Production Line have a more concrete existence as primary materials, which are pulverized to create powders. This powder processing technology converts bulk materials into fine particles with size distributions suited for the desired application.

The primary raw material for powder metallurgy is metal. It may be in the form of a pure metal or an alloy. The resulting powder can be used for a wide range of applications including transportation, machinery, electronics, aerospace, biological, nuclear and new energy fields.

A number of methods are used to make metal powders, including solid-state reduction and atomization. The former involves selecting a selected ore, crushing it and heating it to remove the carbon and oxygen. This produces a sponge-like material which is crushed, separated from non-metallic material and sieved to produce the powder.

The latter involves a plasma-based atomization process. Unlike other powder production techniques, the initial feed for this technique is a metal wire. This is fed into a plasma torch which disperses the wire into particles. The result is an alloy powder with highly spherical particles and low oxygen content. The powder is then ready for use in the sintering process. The powder is recoated with magnesium stearate to protect it from agglomeration during sintering and reduce the need for re-grinding.

Dimensional Requirements

The powder production process comes with wide-ranging design-for-manufacturability (DFM) guidelines. filling machinery Some of these are based on the physical limits of the process; others reflect your project’s requirements. For example, if your structural metal component requires a planar surface over 16 sq. in., it will probably need to be produced as multiple components or via additive manufacturing.

In terms of dimensional requirements, metal powder’s density is a major factor in its compaction efficiency. The more dense the powder, the higher the compaction pressure needed. The specific surface area of a powder is also an important factor: it depends on the size, shape and particle surface conditions. It also includes the amount of entrapped gas from the atomisation process.

To minimise entrapped gas, it’s best to use an atomisation method that produces a relatively small PSD, and ideally with a smoother surface finish. This can be achieved using a high-pressure die compaction cycle, or through a Hot Isostatic Press (HIP) cycle. Both of these processes will generate pores and defects, so a post-compaction heat treatment is often required to minimise these effects. Depending on the application, it may also be necessary to perform a post-compaction sintering. This will help reduce the permeability of the final product and improve its fatigue resistance. In addition, sintering will re-align the grain boundaries of the part, improving its mechanical properties.

Cost

A wide variety of materials are used in powder production lines. Iron is the least expensive, while more exotic iron-based metals have higher costs. However, it is important to consider the total cost of production when choosing a powder metal solution. A more accurate measure is to compare the cost of a finished part to other manufacturing options, such as traditional machining.

As a result of advanced compaction methods and innovative sintering practices, today’s powder metal parts often compete with those made by casting, forging or machining. This is why it is so important to work with your manufacturer early in the design process to find the lowest-cost option that will still deliver the performance you need.
