Pressed steel vs. Cast steel – what is the best choice for your production needs? The answer always depends on many factors, such as the part’s application, the manufacturer’s budget, the size and timeline of production, the part’s approval, the finish, and any other specific manufacturer’s requirements. Steel stamping and steel casting very different processes in metal production. During press, the steel feed to the machine and then pressed and shaped into a specific part. To make steel, the steel is heated in a furnace. Poured into a mold where it cool and then remove.Mechanical Power Press

Each type of steel has specific strengths and weaknesses, mostly processes. Cast iron parts can safe and complex without losing tolerance, and the pressing method can produce a large number of simple parts in an inexpensive manner. Understanding the advantages and disadvantages of each method. And considering all options can mean the difference between reliable parts or deformed parts that need to be replaced quickly.

Despite this process, almost every industry that needs metal parts and components uses one of these methods, from agriculture to defense. This article discusses the processes, advantages and disadvantages of pressed steel over cast steel.

Process sealed steel

When deciding between using the pressed steel method and the cast steel method for the production of parts, it is important to first consider the production process. Metal stamping involves feeding sheet metal into a press in which the tool and die are used to quickly form the desired part or component. While the term ‘pressing’ is used to describe this type of metal production, the metal can be shaped using a variety of processes.


Also known as printing, this process feeds the sheet metal into a press, where the tool and star become a metal part.
Drawing: This is the pressing part of the production process, which forms the basic shape of the workpiece. The two types of drawing are shallow and deep. Although it’s the same as embossing, drawing is used to make parts that are deeper than stamping can.


As the name suggests, the iron part is placed on the star and a ram is driven into the metal, creating the desired bend.

Embossing: This process uses male and female rollers to create raised or recessed sheet metal patterns without changing the overall thickness.
Notching: This method is a cutting process that uses a punch press to extract parts of the workpiece.

Punching: For this process, a special punching press is used to make holes in the pressed steel plates.

Die-cutting: Typically, the first step in the manufacturing process is die-cutting, which cuts large parts of the spiral like a steel sheet into small pieces. Piercing: This will cause holes, crevices or other types of cuts to be made in the metal parts.

Roping: A separate process that simultaneously bends and cuts sheet metal to create tongues or holes in the workpiece.
Clamping: This is a unique manufacturing method in which the vertical walls of a part are cut by clamping metal between two parts of the tool.

The above processes are not mutually exclusive and it is common for the pressed steel to go through several press steps before the desired part is ready. This flexibility in production makes press steel vs. Cast steel is a desirable choice in some industries.


Steel sealed applications

The use of press steel versus cast steel is a popular choice in many industries. Sealed metal parts remain an important building block for countless manufacturers. These parts can be found in electronics, cars, devices, medical supplies, and even airplanes. The sealing steel production process enables the production of the most sensitive components in many industrial houses.

Here are some industries that use pressed steel in their daily activities

The aviation industry requires strict adherence to quality and accuracy. Partial production is carefully documented with the ability to make changes in real time without sacrificing costs.

Fluid Power uses powerful hydraulic and pneumatic systems that require complex equipment to stay functional. Metal parts, such as valve seal components, hooks and mounting flanges, are sealed and used in high pressure and harsh environments.

The medical industry requires longevity and precision because its equipment has a direct impact on human health. Metal stamping ensures precise construction and inspection of critical components.

Oil and gas operations depend on safety, quality control, and efficient components. Gaskets in this industry are used to make internal gaskets, washers, hooks, and handles that withstand all the dangers of the industry.

Cut pressed steel?

Oxidation is a scary word in almost every industry that requires metal parts and components to function. Pressed steel is valued for its longevity and durability, but it needs help to get far.

Alloys are usually added to steel and various finishing methods use to produce stainless steel.

So it’s embossed steel rust? The answer is, it depends.

Corrosion resistance depends on the percentage of elements in the iron mixture. Alloys such as chromium. And nickel can help improve corrosion resistance and corrosion that can be virtually corrosive.


Steel casting process

Significant differences in pressed steel vs. Cast steel parts come from how the part make. Steel casting exist for centuries, which testifies to its value. Steel castings therefore used for rigid machines and must able to withstand heavy loads, vibrations, and continuous use. During production, the molten metal pour into a preforme mold. The metal then cool and the part can remove and finish depending on the manufacturer’s specifications. There two popular methods for forming steel, seal forming, and sand forming.

Investment cast steel

Investment casting also know as lost wax casting. And value for its ability to produce highly detailed parts. This method is applicable to non-ferrous and ferrous metals such as alloy steel. The patterns for the finished part are assembled inside a single wood mold, so it is easy to produce multiple parts in one cycle. Steel melt casting can produce parts weighing more than 1,000 pounds; however. It is more common to shape lighter parts using this method.

Sand cast steel

Metals with high melting points have limited possibilities for cast parts. Sand molding uses non-recyclable sand molds. Which a flexible and cost-effective option for the production of steel gutter parts. The pattern for one or more functions arranges in a sand mold. As with other molding methods, the liquid metal immediately pour into a mold and allowed to cool. The part then remove from the mold and the sand can reuse to create a new mold in the following molds.

Sand molding

Sand molding can produce parts that weigh only a few ounces to several tons and have different shapes.

Each steel forming method is suitable for a specific industry.

Application on cast steel

Turbine engine manufacturers follow strict standards and strict approvals. Fuel system components, various cabinets, hardware. And support systems make by investing. The defense sector needs components that can withstand high temperatures, different climatic conditions and have a long service life. Steel use in weapons, propellers, valves, and launch components. Mining requires unstable and hot parts to maintain operation. The components of the grate, brush, and feeder depend on the parts obtain.

The railway industry uses cast steel for wheels, rail holders, wheel hubs, assemblies. And other products. Characteristics of this size and strength can easily achieve by press.

Cast steel and brittleness

It is common for manufacturers to inquire about steel and its fragility. The material consider brittle when broken without significant plastic deformation and slight elastic deformation. Depending on the composition of the alloy. the steel may be brittle at lower temperatures, which not suitable for some applications.

Stainless steel

Stainless steel withstands sudden impacts without deformation or breakage, making it a good choice for parts that need to withstand high stresses. Steel has the ideal combination of ductility and strength, making it a master of structural and mechanical applications.
