Metal components play a huge role in various industries from aeronautical, agriculture, oil and gas, or even consumer appliances. Every industry needs metal parts that are unique to individual applications. A deep understanding of various production methods can help you choose the right one for your metal part requirement. Die stamping, is a cold-forming process that transforms metal sheets into metal parts designed for various applications.
Metal stamping is gaining popularity, as it produces high-quality precision metal parts at an optimum speed.
This article gives an overview of progressive stamping- one of the most widely used metal stamping processes.
What is progressive die stamping?
Progressive metal stamping is a technique where the metal sheet progresses through a series of metal stamping operations to convert into the desired shape finally. It uses advanced techniques like automated progressive dies to create precision metal stamps at high speed.
This technique is similar to transfer die stamping. Here, the difference is that the die stamping metal sheet is lifted and transferred from one station to another. The metal sheet goes through various workstations.
Some of the common steps that are simultaneously involved in progressive stamping include:
- Coining: Flanging: Piercing
Steps involved in Progressive Die Stamping Process
Progressive metal stamping uses progressive stamping die press where the metal strip is pushed through various stamping stations. The sequence of metal stamping stations is decided to ensure minimal scrap and maximum precision.
The progressive stamping die presses are either mechanical or Hydraulic stamping presses.
A mechanical is a flywheel-driven system where the electric motor is connected to the flywheel over a spin belt. The flywheel is attached to a gear and clutch system that drives the
stamping process. This stamping dies press produces metal parts faster than a hydraulic system.
A hydraulic metal stamping press uses a hydraulic pump connected to a cylinder. The pump brings down the die slides onto the metal sheet. The pressure with which the die stamps on the metal sheet is preset. When the pressure surpasses the preset value, the sliders go down. Automation makes it possible to control the processing speed by adjusting the stroke per minute rate and other parameters.
The press cycle starts once the metal sheet is placed on the progressive stamping die. Here, the top die first goes up and creates space for the material to be placed on the die.
Next, the progressive metal stamping die comes down, closes, and performs the pre-decided metal stamping operation. The custom metal stamping die is always under scrutiny to produce impeccable quality and precision. At Eigen, every process goes through a quality check-up and ensures it matches the design requirements. Sometimes it also uses butter-shaped pilots.
Advantages of Progressive stamping
Progressive stamping offers the following advantages over the basic metal stamping process:
High production speed
Progressive stamping involves continuous feed on the metal. It offers a low production cycle time per part. So you can produce more metal parts at a higher rate at any time.
- It is apt for manufacturing pitch-perfect metal shapes.
- Progressive metal stamping produces metal parts of high precision.
- High repeatability rate
- As progressive stamping uses hard-tooling techniques to manipulate the metal, the dies last longer. It, in turn, increases their repeatability rate.
Should You Use Progressive Stamping?
It is true that programming stamping has a high repeatability rate and is faster. However, it is a complex process that needs time and expertise. The initial cost is high, but progressing stamping die can create highly accurate metal parts at the optimum time and cost with proper maintenance.
Progressive metal stamping is an effective complex metal stamping. The process requires expert supervision at a low production cost. The metals used for progressive stamping are good malleability, ductility, and tensile strength, such as brass, stainless steel, steel, copper, and aluminum.
Choose the right progressive metal stamping partners.
The key to producing top-notch quality complex precision products is to outsource the metal stamping requirements. With so many metal stamping partners available in the market, it can be an overwhelming experience to decide the right one for your business needs.
