Why Metal-Stamped Components are crucial for the Aerospace Industry

Commercial aviation manufacturers continually strive to improve their vehicles’ fuel economy and passenger comfort. Additionally, aerospace OEMs must adhere to stringent safety guidelines as specified by governments and industry groups. These competing pressures mean that aviation components must be designed to the tightest tolerances possible. At every step of the process, from concept to tooling to production, aerospace manufacturers must satisfy strict quality standards.

Aerospace Metal Stamped Components

Many aerospace manufacturers are able to meet the slew of requirements through the use of metal stamping. This technique allows manufacturers to create high-quality precision components that can meet strict specifications. It can also work with and produce metal parts of all sizes, granting aerospace manufacturers a wide range of abilities when using this technique. This has led to a broad spectrum of aerospace equipment that owes its creation to the innovative use of metal stamping.

Providing Accurate Components Across the Industry

Aerospace industry regulators require manufacturers to adhere to rigorous quality controls and provide ongoing documentation to comply with national and international standards. One of the most important metrics that aerospace projects must satisfy is AS9100, which is part of the ISO 9001 aerospace standards. In order for aircraft to be approved by governmental bodies like NASA, the DoD, and the FAA, it must first accord with AS9100.

AS9100 standards require aerospace manufacturers to document all processes they use to design and fabricate components. This enables inspectors to better locate errors in the production process in case malfunctions occur later down the line. Stringent documentation also helps manufacturers review production plans so they can identify areas in which they can improve their processes, helping them produce sufficient quantities of parts that satisfy demand.

Every aerospace manufacturing project must prioritize component reliability. Because even the smallest types of aircraft are highly complex machines, each component within them must be ready to perform with maximum accuracy at all times. It’s a constant challenge in aerospace manufacturing to find the highest-value components while staying within demand and budgetary constraints.

Common Types of Metals and Applications

Metal stamping allows aerospace manufacturers to efficiently work with high-quality metals using cost-efficient and time-efficient processes. This technique can work with a broad range of high-quality metals essential to aviation projects, such as:

  • Steel
  • Stainless steel
  • Carbon steel
  • Aluminum
  • Galvanized steel
  • Cold-rolled steel
  • Titanium
Aluminum Stamping for Aerospace Applications

A Closer Look: How Metal Stampings Work

Metal stamping is used across a huge range of industries. Original equipment manufacturers (OEMs) typically utilize metal stamping to produce parts in situations in which casting would be too expensive. Metal stamping is much more cost-efficient, as sheet metal is easily recyclable.

OEMs, especially those in the automotive, appliance, and aerospace industries, often drive the need for metal tooling. Some OEMs produce their own stamped metal parts onsite, while others outsource to Tier 1 suppliers. These suppliers build the dies for stamping down the line.

Metal Stamping Components and Processes

A metal stamping operation involves a metal being cut and formed into a desired shape or profile. Three basic items are essential: the metal from which the part is to be made (typically steel, though all kinds of metals can be used, including golds and advanced super alloys), the stamping press, and the stamping die. During metal stamping, a flat metal sheet, also known as a blank, is pressed between a die and a punch to achieve the desired shape.

These parts comprise the press:

  • Blank — The portion of the metal that is punched through the die
  • Die — Defines the outside shape of the part
  • Punch — Defines the inside shape of the part
  • Ram — Component that presses down on metal with upper die pattern
  • Bolster plate — Stationary lower part of the die
  • Blank holder — Holds the blank for control during stamping

As blanks are punched out of the sheet metal, they come through the die, which is built with a slight angle so blanks don’t get stuck inside. Punch presses are powerful machines. It takes about 71 tons of pressure to cut a 10” circle out of 0.125” sheet metal. Modern presses range from 10 tons to 50,000 tons of force.

There are a number of workers involved in the metal stamping process. A machinist cuts die components to correct dimensions. A diemaker tests dies for consistency and assembles stamping tools. A maintenance technician repairs and maintains stamping dies, correcting any problems.

Some parts require further work after stamping. During deep drawing, for instance, a flat blank is slowly drawn over a forming die to achieve the desired shape. Excess material is cut from the deep drawn metal. The metal might then need to be flanged.

How Metal Stamping Can Impact Your Bottom Line

If you’re looking to increase your bottom line without sacrificing the quality of your product, consider metal stamping. To create new components, stamping presses transform metal blanks into desired shapes through the use of a tool and die. With a variety of modifications, metal stamping can create numerous shapes for your product, giving you greater versatility. It also offers a number of benefits including reduced product costs, shorter production time, and extended product lifespans.

To maximize metal stamping’s impact on your bottom line, here are some helpful tips:

1.      Reach out to your metal stamper early in the process

Getting your stamper involved from the start can save you considerable time and money later on. Often, there is a disconnect between the manufacturer’s envisioned design and what the stamping engineer can actually do within the limitations of metal stamping. If the manufacturer and metal stamper collaborate together early, however, they can eliminate such disparities and make improvements to optimize the design –– ultimately saving you production time and money.

2.      Forecast your requirements & Reduce costs

It’s important to share with your metal stamper your assembly process, projected volumes, release dates, and lead times for your product. If they have as much information as possible upfront, metal stampers can ensure a smoother production process from start to finish. For example, they may be able to redesign the stamp to reduce costs and streamline manufacturing.

Since production volume directly impacts costs, be sure to let the stamper know the volume at which you plan to produce the parts. In addition, providing your expected lead time can remove the need for rush jobs and build in time for extra review, modification, and production changes — eliminating extra costs.

3.      Assess the dimension for final assembly

Knowing exactly how a single part will fit into the overall design is very important when assessing your project budget. If you provide accurate dimensions for your part’s assembly, the metal stamper may be able to use in-die assemblies that can eliminate unnecessary manufacturing steps, reduce labor and production costs, and speed up the time to market.

4.      Evaluate simulations and prototypes

Be sure to test the design and functionality of your product before fully launching its production. Metal stampers have the ability to create prototypes and simulations that test how well the designed product will perform under certain conditions. If you find problems or issues, you’ll then be able to adjust the design to improve the product’s durability and function, as well as optimize its production. By using these simulations and prototypes, you can perfect your design before wasting any valuable time or resources in making something that won’t actually work.

Three Metal Stamping Trends to Look Out For in 2017

Thanks to several innovative technological developments, the metal stamping industry has seen steady growth. Advancements in robotics, automation, and numerical controls have all helped improve stamping precision and speed, while virtually eliminating setup time.

Metal-Stamping-Trends-2017With rising global consumer demand, the industry is expected to continue riding this growth wave through 2017. Here are three major trends you can expect to see in the coming year.

  1. Reshoring and the Growth of Manufacturing in America

You’ve probably heard about the surging reshoring trend in American manufacturing; after decades of outsourcing production and contract manufacturing, many companies are now considering the financial benefits of moving their operations back to the United States.

Today, reshoring actually results in a higher total cost of ownership than domestic production — despite the higher labor costs at home. Advanced automation techniques will allow the precision metal stamping industry to easily take advantage of the various business opportunities that will soon be sprouting up as more OEMs reshore their operations.

  1. The Rise of Solar Paneling

Significant price drops for photovoltaic (PV) systems have made solar power much more popular. Not only can metal stamping companies benefit from the energy costs savings and federal tax credits associated with switching to solar, but they are also uniquely positioned to service this growing industry; PV installations require many kinds of precision machined parts to support the metal panel frames.

  1. Integrating Automation in Production

Automation integration yields a two-fold benefit for manufacturing companies: higher production rates at lower costs. Utilizing advanced equipment such as laser cutters offers metal stampers unparalleled precision and speed for optimized production. Meanwhile, implementing robotics for repetitive tasks lowers the headcount in the shop while freeing up skilled machinists to take on more challenging work, such as programming.

9 Metal Stamping Processes to Consider

There is much more to metal stamping than most people take into consideration.
Complex parts often require a series of several different steps to create. Parts that may seem simple at first glance rarely need only one stamping step to be considered properly completed.

Confusion is often found when determining the appropriate process for metal stamping. When selecting a metal Metal Stampingstamping process, one should consider:

  • How the stamping process will impact the functionality of the design
  • The design or industry-specific requirements
  • Production time and cost-effectiveness

Common Metal Stamping Processes

Disregarding steps such as design and prototyping, which are necessarily performed prior to stamping, there are nine primary processes involved in the actual stamping of metal parts.

Blanking

When required, blanking is the first step of the stamping process. Blanking is the process of cutting larger sheet or coils of metal into smaller, more manageable pieces. Blanking is usually performed when a stamped metal piece will be drawn or formed.

Piercing

If a part requires slots, holes, or other cutouts, piercing can be employed. Piercing, which can be performed simultaneously with blanking, punches the requisite shapes out of the metal sheet.

Drawing

Drawing is the actual stamping in the metal stamping process. A punch forces a section of metal through a die, providing the primary shape of the part. When the depth of the part is less than the primary opening, it is considered shallow drawing; parts with a depth greater than the opening are deep drawn.

Bending

Bending is a fairly self-explanatory process. The part-in-progress is placed on a specially designed die and a ram pushes against the metal, providing the required bend. Bending is performed after drawing, as attempting to punch an already bent piece of metal causes the entire part to deform.

Air Bending

Air bending is when the flat surface of a part is bent by a punch into a die, often V-shaped. The space between the punch and die is larger than the metal thickness, resulting in a bend that relaxes slightly when the part is released. Air bending uses less power and pressure than other bending methods.

Bottoming and Coining

Bottoming and coining are bending processes are similar to air bending, but use anywhere from two to 30 times the pressure and the material is forced fully into a tight-fitting die, resulting in a more permanent bend.

Forming

Forming is a bending process similar to bending, bottoming, and coining. It creates parts with multiple bends, such as U-bends, in one step.

Pinch Trimming

Pinch trimming is a method of cutting a piece from the metal sheet, separating it from the scrap metal. It is an unconventional process: the metal is pinched against a flat vertical surface. It is often, but not exclusively, used to cut deep drawn round cups from the sheet.

Lancing

A unique process, lancing is a type of metal cutting used to make vents or tabs. A section of a part is cut along three edges and simultaneously bent. This creates the opening or hook-like feature required but eliminates a scrap collection or secondary machining step.

There are many different processes involved in the stamping process and, clearly, not every process is the best, or even required, for every part. With a full understanding of the processes, you can better design parts to minimize scrap, create cost savings, and increase production speed without ever sacrificing quality.
