Have you ever pondered the creation of intricate and complex brass parts? This is a fascinating process that combines engineering precision with art. Our brass extrusion capability allows us to produce metal components customized according to exact specifications.

Brass extrusion, or die-pressing, is a process in which brass is pressed through a die and shaped into a long shape with a particular cross-sectional pattern. We excel at this technique, resulting in durable and precise components.

It’s not only about forming metal but also about creating new possibilities. Every piece is purposefully engineered to serve a distinct function in vehicles and home appliances.

Brass Extrusion: Basics

Shengen has been perfecting brass extrusion as an art form. Our expertise in transforming metal into precision components is really on display here. Let me guide you to a basic understanding of brass extrusion and why it is essential in our industry.

What is Brass Extrusion?

Brass extrusion is a process that involves pushing brass through a die, a soft, malleable metal with high strength and flexibility. The result is objects with a defined cross-sectional shape. This process enables the production of lengthy items with intricate cross-sections, customizable to any desired length. In our facilities, we apply this technique to craft diverse products. These items vary in size and shape to meet the precise needs of our clients.

History of Brass Extrusion Technologies

Brass extrusion dates back to early industrial times but has changed significantly. The process used to be crude and needed more precision and efficiency than we enjoy today. We’ve refined our craft through technological advances, from manual labor to automation, rough shaping to precision engineering. The evolution of brass has enabled us to create the impossible.

Critical properties of brass that affect extrusion

To master the extrusion technique, one must first understand the properties of brass. Brass is a copper-zinc alloy that can have its composition altered to produce different properties. Brass is ideal for extrusion because of its high malleability. We choose brass for its excellent electrical conductivity and ability to resist corrosion.

 Brass has many inherent characteristics that allow us to produce high-quality extruded components and meet our industry’s standards.

Brass Extrusion Process

The complexities of brass extrusion captivate engineers and manufacturers alike. We at Shengen consider this process the heart of our production. We’ll explore the techniques and steps that turn brass into the custom parts that our customers rely on.

Prepare the Brass for Extrusion

Selecting the suitable alloy and its composition

The suitable brass alloy determines its properties and suitability for various applications. They select the alloy’s composition to meet specific needs for strength, corrosion resistance, and ease of machining in the final product. Designers ensure that extruded components perform optimally for their intended use.

Billet preparation and heating

Once we choose the suitable alloy, we prepare brass billets for extrusion. Workers cut the brass into manageable sections and then heat it to a temperature that renders it pliable. The heating process directly affects the quality of extruded metal.

Extrusion Machinery

Types of extrusion presses

Extrusion presses are available in different forms, each with a specific purpose. Hydraulic presses provide control and power for complex profiles. Mechanical presses are more suitable for simple shapes. The complexity of the design, as well as the volume of production, will determine the choice of press.

Design and material of Tooling and Dies

Tooling and dies form the core of brass extrusion. Designers create these components with precision. This ensures that the extruded brass meets the exact specifications. Dies are typically crafted from high-grade steel, which can endure the intense pressures and temperatures of the extrusion process.

Extrusion Operation

The Step-by-Step Procedure

Brass extrusion is a complex process that requires precision. The heated billet is placed into the press and pushed through the die to achieve the desired shape. Years of experience and technology help to manage the complexity of this complex process.

Temperature and speed controls

It is crucial to control the temperature and the speed of the extrusion. This affects the metal’s workability and the final product’s structural integrity. We closely monitor these parameters and make adjustments in real-time to ensure consistency and quality.

Post-Extrusion Treatments

Cooling and Straightening

After extrusion, we cool the brass profiles slowly. This careful cooling preserves their mechanical properties and shape. We use various cooling techniques and straightening processes to align the extruded pieces perfectly.

Surface finishing and heat treatment

Surface finishing and heat treatments are the final steps that improve brass’s appearance and strength. We offer a variety of finishes, including polishing, anodizing, and lacquering. Heat treatment is also available to ensure the component performs well in its final application.
