What is Sheet Metal Fabrication?
Types of Sheet Metal Fabrication
Laser Cutting
Laser cutting involves etching materials, or cutting etching materials with a focused beam of a laser to create precise edges and complex patterns to the specifications of the designer through vaporization or melting.
Punching
Punching is a metalworking technique that uses a punch press to punch holes, notch or otherwise shape metal sheets. It is an affordable method of producing parts of high precision and can be used in repetitive production.
Bending
Metal bending refers to the act of bending the metal through a press brake or roller to the shape or angle required. This technique is best used in making parts that have sharp, angular bends and is needed in those industries in which precise angles are necessary.
Why should you choose our services in metal bending?
We offer custom metal bending at Top Proto to ensure that your parts fit and are in shape. We will manufacture your parts according to your exact specifications using our top-quality machinery and professional workforce.
Precision Bending: Accuracy within a range of± 0.1⟯mm, so there is nothing wrong in any project.
Flexibility of Materials: We deal with more than 50 different metals such as stainless steel to aluminum, depending on your requirements.
Effective Production: Our high volume production and rapid prototyping ensure that we produce your parts on time and every time.
Certified Quality: Our metal bending services are of international standards i.e. ISO 9001: 2015 and ISO 13485 and are of high quality in terms of quality and performance.
