Metal Forging Companies

metal forging companiesWhat is Forging? Forging is a manufacturing process which involves the forming and shaping of metals using localized and compressive forces. The blows are delivered to the metals with a hammer (see drop hammer forging for reference) or a die (open die forging or closed die forging). The type of forging processes are often classified in accordance with the temperature at which they are performed: cold forging, warm forging, or hot forging. For the latter two, the metal is heated, usually in a forge.

Common Types of Forging

Four methods allow metal forging companies to create precision components for a number of commercial applications. Consider these four types as you review metal forging companies:

  1. Cold forging
  2. Seamless rolled ring forging
  3. Closed impression die forging
  4. Open die forging

There are pros and cons to each type, but our team at Trenton Forging specializes in closed impression die processing. We use two dies, or tooling, that are pre-cut to the precise profile of your desired part. Whether manufacturing a single prototype or a bulk order, we take care in creating accurate tooling for a reliable finished product.

Closed Die Forging

Closed die forging uses extreme temperatures, unlike cold forging. It offers a wider range of part manufacturing capabilities than a seamless rolled ring process. Unlike an open die, closed die forging uses custom-made plates, which removes additional finishing steps in the process.

Increase the strength of your manufactured metal components through closed die forging. Compared to a molded part, forged components have improved integrity and less risk of bubbles or other inconsistencies. The slug is struck once or multiple times until the tooling impresses the full features onto the workpiece.

We carefully control the process through skilled operation of an air lift. This process ends with steel components that can last up to four times as long as parts manufactured with another process. It also produces less waste material.

Common Metals Used by Metal Forging Companies

Metal forging companies carefully compare the features of common and specialty alloys to create optimal product features. The metal selection process starts by considering the demands of the final product. Next, alloys are compared and chosen to suit the final component and the forging process. As a leading American forging company, Trenton uses these and other common metals for our customs forging services:

  • Steel
  • Stainless steel
  • Steel Alloys
  • Microalloys

The weight, strength, temperature performance, cost and other factors are all weighed and discussed with you until we arrive at the optimal metal. These are the most common metals used at our metal forging company, so discuss rare alloy use to create a specialized workpiece for your industry.

Steel Forging

Steel comes in an incredible range of grades and alloys. As you compare everything from 100 to 600 series steel, work with Trenton to achieve the results you need. We strive to outpace other metal forging companies in our commitment to quality materials and exceptional forging precision. Consider our steel, stainless steel and steel alloy options as you discuss the optimal choice for your components.

Martensitic

Steel that is martensitic goes through a quenching process to capture carbon in the structure. While this material has less chemical resistance than austenitic steel, it has high levels of hardness. It’s commonly used in creating cutting edges.

Austenitic

Austenitic crystal structures absorb about 2% carbon to create corrosion-resistant products. The steel must be heated to around 912 degrees Celsius. It often needs nickel or manganese to retain the austenitic properties after being exposed to high temperatures.

Ferritic

When iron atoms create a ring around an individual iron atom, it prevents carbon absorption and creates ferritic steel. This product offers limited corrosion resistance and only has average levels of strength and hardness.

300 Series Steel

Stainless steel is divided into 200, 300, 400, 500 and 500 series of alloys. Each series offers multiple types. These differences can reflect whether an alloy is austenitic, ferritic or martensitic, but also reflect other metals introduced into the steel structure.

300 series steel features chromium-nickel austenitic alloys. It includes surgical and marine-grade type 316, as well as the most common grade of stainless steel, type 304. Type 301 is another popular 300 series alloy that is easily weldable and ductile enough for use in formed manufacturing processes.

400 Series Steel

Consider a chromium alloy with either martensitic or ferritic properties. The 400 series includes iconic options like type 409, used extensively in automotive exhaust manufacturing, and type 420, another surgical-grade solution. Type 440 is another popular option for cutting blades, often used as cutlery steel.

Types of Forged Products

Metal forging companies create dependable steel components for a diverse range of industries. Some of the typical industries and types of forgings which are manufactured for them include:

  • Industrial Equipment From cylinders and shafts to blocks and sleeves, industrial equipment uses a number of steel components that need to work in demanding applications. We work with power generation, paper processing, steel milling and refinery industries to manufacture or repair massive machinery for industrial use.
  • Railroad/Off-Highway Equipment Trains, mining equipment and construction equipment all use forged materials. We can create wheel hubs, axle beams and ball joints for these durable machines.
  • Tool and Hardware Forging is also a convenient way to create hand tools. Surgical instruments can also be forged using a suitable alloy and precision dies. Consider this process whether you need a single tool or a bulk order of hardware.
  • Valves and Fittings These components are used in hydraulic systems and other industrial applications. Work with our team to create corrosion-resistant fittings and valves to handle any process liquid.
  • Agricultural Equipment Balers, tractors and other agricultural equipment need specialized components that can withstand heavy use. Consider forged products for improved impact and fatigue resistance.
  • Military Armored military vehicles and ammunition both use forging and high-quality alloys. We work with precise specifications for reliable military hardware. A forged military component may use a specialty alloy or a common stainless steel type for reliable durability.
  • Aerospace Lightweight items with high strength ratings are possible through forging. Order wing roots and spars, arresting hooks or other aerospace components forged from state-of-the-art alloys. Discuss alloy selection to achieve the best balance of strength, precision and lightweight performance.
  • Automotive Perhaps the most iconic industry for forged materials is the automotive industry. Axles, ball studs, steering arms and other components are custom forged to produce results that last. These parts need to hold up to heavy use, sudden shocks and extreme weather conditions. Forged products create the components you need.

Forging vs. Casting

Forging allows you to create precise, reliable components, however because of the nature of the process their are limitations to the size and the weight of the forgings.

Casting, however, can be used to create much larger products. Casting heats metal until it becomes a liquid that can be poured into a custom cast. While casting offers more flexibility in part dimensions and weight, it can’t compete in terms of reliability and long-lasting performance. Forging offers uniform structure and composition for refined grains and impressive mechanical strength.
