A Practical Guide to Understand Metal Stamping Press

Metal Stamping suppliers

The topic of metal has remained popular in every era. It is particular famous in connection with modern technology. In reality, however, logam is an ancient craft that over the centuries became an advance technique.

What is metal stamping?

Stamping logam is a controlled deformation process in which the body changes its shape under the influence of excessive pressure. Thanks to such processing, metal products are given the most diverse forms that they need to fulfill their functional duties.

Stamping gives in to parts of small thickness, since bending thick products is very problematic.

How metal stamping is carried out?

Metal stamping allows you to quickly and accurately shape the original sheet material into a finished product.

This process consists in the deformation of the metal under the action of directional pressure. In this case, the material changes its shape, while maintaining the initial thickness of the sheet.

 

The main types of metal stamping

This method of processing is used in small, medium and large volumes in industries.

Stamping of metal products is used in almost all industries. Moreover, it allows you to create any kind of detail. This technology has a very long history and is now actively developing.

New methods are constantly emerging that use forces of different origins other than gravity. Similarly, deformation occurs under the influence of:

  • hydraulic pressure
  • electric current
  • Magnetic field, etc.

Next, we will consider issues related to the principle of operation of:

  • logam
  • types and
  • methods of metal deformation
  • The use of products created in this way in various industries.

What is sheet metal deformation?

Deformation of sheet metal can be carried out under the influence of high pressure. Based on this, all types of stamping can be divided into two large groups:

  • cold;
  • hot

Secara umum, kedua tipe tersebut memiliki kelebihan dan kekurangan yang membatasi ruang lingkup penggunaannya. Cold stamping dilakukan pada suhu di bawah titik leleh logam.

Selanjutnya, ini menghindari penyusutan selama pendinginan. Tapi itu memberlakukan pembatasan pada bentuk produk akhir. Cara ini membuat suku cadang tanpa banyak elemen timbul, misalnya bagian bodi mobil.

Persyaratan utama untuk bahan yang digunakan selama pencetakan logam adalah keuletan yang tinggi. Selain itu, metode ini cocok untuk:

  • rendah karbon dan baja paduan
  • tembaga
  • Kuningan
  • paduan aluminium dan magnesium, dan

 Hal berikut diperlukan untuk stamping logam:

  • Bantalan lembut, kertas logam dan alat pengembos.
  • Jika ingin menjajal tekniknya terlebih dahulu, Anda bisa menggunakan pulpen emboss sederhana dan satu sendok teh sebagai alat bantu.
  • Jika Anda menyukai hobi ini maka Anda harus mendapatkan alat yang tepat. Jauh lebih mudah untuk mencapai hasil yang jauh lebih baik.
  • Alat logamterlihat agak "kuno". Tetapi juga sangat stabil - dan memang itulah mereka! Mereka melayani tujuan mereka dengan lebih baik daripada beberapa alat baru. Karena mereka stabil dan pas di tangan.

Mengapa stamping logam?

Stamping logam  adalah proses manufaktur yang penting, tergantung pada stamping apa yang membutuhkan bentuk dan fungsi. Keunggulannya adalah:

  1. tingkat produksi yang tinggi
  2. konsistensi dan
  3. Biaya rendah.

Stamping Logam diterapkan di banyak industri. Seperti:

  • Otomotif
  • industri berat
  • industri elektronik
  • komponen elektronik
  • aksesoris perangkat keras
  • Aksesoris kendaraan.

Stamping molding technology is a technology for forming a desired shape by combining technologies. Such as:

  • Bending
  • Drawing
  • punching, and
  • Cutting metal plate materials.

It has the advantage of being able to manufacture large numbers of products at low cost. It is one of the main technologies for manufacturing metal parts.

Main mechanical hammers used in forging

Modern forging machines mainly include mechanical hammers and press machines.

First, there are two main types of mechanical hammers used in forging:

  1. air hammers
  2. and spring hammers

What is hydraulic metal stamping?

A hydraulic press is a press machine that uses the pressure of a cylinder into which water or oil is fed to perform processing. The load and speed can be controlled by adjusting the hydraulic pressure sent to the cylinder.

Potensi  logam  stamping

The sheet logam adalah proses produksi yang memungkinkan Anda membuat benda dan produk logam mulai dari lamina. Itu dikompresi dan dicetak menjadi berbagai bentuk dan ukuran tergantung pada jenis alat.

Lembaran ini diterapkan di banyak sektor, dari furnitur hingga elektronik, dari objek hingga pemanas, dari makanan hingga sektor industri.

Stamping lembaran memungkinkan menghasilkan objek berkualitas tinggi dengan biaya rendah. Bahkan ketika bentuk dan karakteristiknya sangat rumit dan kaya akan detail.

 

Ini karena mesin yang digunakan dalam produksi dan proses produksi sangat canggih dan mutakhir dalam segala hal.

The fastest and most efficient sheet metal pressing technique is the cold one. Let's look at how it works.

What is cold stamping of sheet metal?

The cold sheet is the most convenient and rapid type of industrial molding. Because it is operated at ambient temperature, without requiring the heating of machinery and metal plates before machining.

Generally, it greatly reduces the waste of energy, economic and temporal. This is why many companies use it for sheet metal stamping in Turin and throughout Italy.

Conclusion on metal stamping

It's used for a very long time. Since it comes from the forging of metals - a process that develops together with humanity. without which it is impossible to imagine the creation of tools, construction tools and weapons.

Modern methods of manufacturing parts require not only high precision, but also material savings. While cutting metal, a very large part of it goes into chips  maximum rationality. It consumes material, giving it a shape that practically does not need further processing.

Metal Stamping manufacturers

Although the presses used for logam are constantly evolving, increasing power and productivity. Their technical characteristics sometimes do not allow the creation of parts of very large sizes.

In this case, alternative methods come to the rescue. Such methods use hydraulic, explosive and electromagnetic forces.

The introduction of these methods into production allows you:

  • to reduce the consumption of materials
  • increase the accuracy and
  • reliability of products and
  • speed up the production processes.
