Metal Forgings Suppliers

Forging Hammer Process

As one of the oldest forms of metalworking in existence, metal forging has evolved to become one of the most vital manufacturing processes for transforming raw metal into custom shapes. Today, metal forgings manufacturers use powerful hydraulic, compressed air, or electric hammers with reciprocating weights that exceed thousands of pounds to produce forged parts that are stronger than a comparable machined or cast metal component.

What are Forgings?

Metal forgings are both an art and a science that uses the power of heat to rearrange the grain of metal. Heat is used to soften, deform, and produce the final finish of a piece of metal. But it is the force of a falling ram or a die press that will squeeze and press the metal into its final form.

When the grains within metal are heated and stressed at high temperatures, the resulting rearranged metal will feature a greater structural integrity that can withstand extreme pressures, even while under stress. Custom forging companies can produce a wide variety of forgings that are used in many industries, including automotive, aerospace, and heavy equipment.

Metal forging presses and hammers are massive pieces of equipment designed specifically to work with hot metal. The forces of vibration and shock generated by a forging hammer or press is absorbed by the equipment and its foundation. The craft of metal forgings demands an operator that can precisely and carefully use heat treating and metal forming best practices to correctly shape the final workpiece.

Common Types of Metal Forgings

Metal forgings suppliers serve a wide range of industries, many of which prefer forged components over welded or fastened assemblies that weaken at connection points. And, quality, forged metal products are without internal voids that can cause product failure when under stress.

Here are some of the industries that benefit from forged components that are stronger due to their more consistent metallurgical properties.

Automotive and Commercial Trucks – from transmission components to steering yokes, U-joints and rocker arms, the drivetrain of motorized vehicles benefit from the strength of forged steel products.

Agricultural Equipment – to meet the harsh demands of an industry that requires constant output, forged parts for backhoes, tractors, and combines keep this industry humming.

Mining and Forestry – it is from parts made by custom forging companies in which tools like auger bits, drills, block cutters, and rock tools are able to drive through hard earth and solid rock.

Railroad – many metal forgings suppliers produce railroad components such as eye bolts, box car hand brakes, coupler pins, and track switching irons.

In addition to these specialty industrials, the everyday consumer enjoys a higher quality product that feature forged metal components including motorcycles, snow mobiles, and firearm components.

How Are Forgings Made?

There are a number of methods for producing forged metal parts, including closed impression die forging, open die forging, along with hammer and press forgings that will shape metal parts through a series of die impressions using repeated blows to the metal.

Open die forging is an extension of press forging where the workpiece is not completely enclosed by a die as it is being shaped. Open die forging can be used for larger components that may weight from 5 to 500,000 pounds, such as shafts and disks.

The preferred method for most forged metal parts uses the closed die forging process. Closed impression die forging is a process where the workpiece is completely enclosed within the die. As each half of the die moves together, the workpiece is totally or partially enclosed.

The heated raw material is poured into a die that is the approximate size and shape of the final piece. Both the top and bottom die are the negative image of the final piece. When pressed into the molten material and impacted by force, the final forged shape is developed.

Forging Vs Casting

When compared to metal castings, both hot and cold-forged products are stronger. The strength and integrity of forged components are more predictable, and will typically exhibit more uniform and superior physical properties versus casting.

Internal metal defects that can arise from cast ingots are refined or removed by the forging process. This is due to the forced flow of the material’s grain into a specific direction caused by forging that is not present in the continuously cast bar. Forged stock is often pre-worked to orientate the grain in a specific direction for maximum metal strength and ductility.

Also, metal forgings manufacturers can produce parts more economically, which results in cost savings for customers. And, a product that is more durable, stronger, and easier to shape due to a higher ductility in metal forging makes forged products perfect for heavy-duty service.

During processing, casting requires very close attention to the melting and cooling phases to prevent alloy segregation. Forgings simply respond better to heat treatments, resulting in a more uniform heat response for greater straightness and better dimensional precision of the final products.

How to Choose Metal Forgings Suppliers

When choosing from metal forgings manufacturers, look for a company that has serviced various industries and are experts in specific metal forging processes. Likely, your projects will have certain deadlines that must be met. Therefore, work with metal forgings suppliers that you can build a relationship with and one that can deliver on time, every time.

Quality forgings are made by companies that have a solid reputation for using high-quality raw materials that result in a strong and durable product. Some companies take shortcuts or use low-quality processes to save money. In the end, these products will have a shorter life span or may result in a failure of equipment.

Fact-check the companies’ history to determine if they are a low-cost, low-quality provider. Reputable metal forgings manufacturers understand how hidden defects deep within the metal forging can cause a catastrophic equipment failure that may put lives and property at risk.

And finally, you should always use metal forgings suppliers that implement cutting-edge solutions that are data-driven. These companies are often certified in forging industry practices and have a higher level of quality assurance that includes process monitoring and product evaluation after forging.

Custom Forgings

Trenton Forgings has over 50 years of experience in delivering custom metal forgings using high-quality steel, stainless steel and steel alloys. Custom forgings are engineered to specifically meet design specifications for both durability and affordability.

Custom forging companies use processes and materials that are designed to ensure a product that is stronger and lasts longer, and with better in-field performance that reduces productivity downtime. When a product is custom engineered, you can expect it to withstand higher impact forces while maintaining the product’s structural integrity.
