Stamping Steel Products at ABC Vietnam
At ABC Vietnam Manufacturing, we specialize in transforming flat sheet metal into intricate shapes using the power of stamping. With years of experience in the metal stamping industry and a team of skilled engineers and technicians, we’re committed to delivering high-quality stamped components for a wide range of applications. In this article, we will describe the machines and steps involved in our stamping steel products factory in Vietnam, as well as how to handle single-step and progressive molds and what post-processing steps can be offered.
What is Stamping Steel?
Stamping steel (also known as pressing) is the process of placing flat sheet metal in either blank or coil form into a tamping machine, where a tool and die surface form the metal into a net shape. Stamping includes a variety of sheet-metal forming manufacturing processes, such as punching using a press or stamping machine. Blanking, embossing, bending, flanging, and coining. This could be a single-stage operation where every stroke of the press produces the desired form on the sheet metal part, or could occur through a series of stages. The process is usually carried out on tubes and sheet metal, but can also be used on materials like aluminum.
Machines Used for Stamping Steel
The main machines used for stamping are:
- Stamping press: A machine that applies force to a metal sheet or tube with a die. The press can be mechanical, hydraulic, or pneumatic, depending on the required pressure and speed. The press can also be single-action or double-action, depending on the number of strokes per cycle.
- Progressive Die: A tool that shapes the metal sheet or tube into the desired form. The die can be made of steel, carbide, or other materials, depending on the hardness and durability required. The die can also be single or multiple, depending on the number of operations performed on the metal.
- Feeder: A device that feeds the metal sheet or tube into the press. The feeder can be manual, automatic, or servo-controlled, depending on the accuracy and efficiency required. The feeder can also be rolled, stripped, or coiled, depending on the shape and size of the metal.
Steps of Stamping Steel
The steps of stamping can vary depending on the type of product and the method of stamping. However, a general overview of the steps is as follows:
Design
In the first step, our engineers collaborate closely with you to understand your product requirements. We leverage CAD/CAM (Computer-Aided Design/ Manufacturing) software to create detailed designs of both the product and the stamping die, ensuring accuracy and functionality.
Fabrication
The second step is to fabricate the (progressive) die, using methods such as machining, grinding, welding, or casting. The fabrication can be done in-house or outsourced, depending on the complexity and quality of the die.
Setup
Our experienced technicians expertly set up the press and feeder, fine-tuning parameters like pressure, speed, and stroke length to match the specific die and material. We primarily utilize coil stock for continuous stamping, enhancing efficiency for large production runs.
Stamping
The fourth step for stamping steel is to use the press and the die, following the sequence of operations such as cutting, bending, drawing, forming, or coining, depending on the shape and function of the product. The stamping will be done in a single step or progressive mode, depending on the number and complexity of the operations. With continued stamping, we will use a coil as the main material.
Inspection
The fifth step we do is inspecting the stamped product, checking the quality, accuracy, and consistency of the product. The inspection is done visually and with instruments, such as calipers and micrometers. In production, calipers and gauges are the primary tools used for quality checks, depending on the standards and requirements of the product.
Post-processing
In the final step, we offer a comprehensive range of post-processing services to add the finishing touches to your stamped parts. These include:
- Assembly: Joining multiple stamped components into sub-assemblies or finished products
- Deburring: Removing sharp edges and burrs for safety and aesthetics
- Cleaning: Thoroughly cleaning parts to remove oils, contaminants, and debris
- Coating: Applying protective or functional coatings like zinc plating, powder coating, or anodizing
- Painting: Adding color and branding to your parts
How to Choose the Right Mold? Single Step vs Progressive
The choice between single-step and progressive molds is crucial for optimizing your production process.
| Feature | Single-Step Molds | Progressive Molds |
| Operations per Press Stroke | One | Multiple |
| Ideal Production Volume | Low-volume, prototypes | High-volume |
| Complexity | Simpler | More complex |
| Cost | Lower | Higher |
| Flexibility | High (easy changeovers) | Lower |
| Efficiency | Lower | Higher |
| Per-Part Cost | Higher | Lower |
