Indonesia has emerged as a significant player in the aluminum extrusion industry, with companies like PT ALCOMEX INDO and PT Alexindo leading the way. The aluminum extrusion process involves transforming raw aluminum into various shapes and profiles, which are used in diverse sectors such as construction, automotive, and electronics. This article will delve into the intricacies of the aluminum extrusion process in Indonesia, highlighting key steps, technologies, and applications.
Introduction to Aluminum Extrusion
Aluminum extrusion is a manufacturing process where aluminum is heated and forced through a die to create a desired shape. This process is widely used due to aluminum's lightweight, corrosion-resistant, and versatile properties. Indonesian aluminum extruders have capitalized on these advantages, offering high-quality products both domestically and internationally.
Indonesian Aluminum Extruders
Companies like PT ALCOMEX INDO and PT Alexindo are prominent in the Indonesian aluminum extrusion market. PT ALCOMEX INDO, located in Cibitung, West Java, operates with a production capacity of 18,000 tons per year, utilizing advanced machinery including UBE Press Machines from Japan. PT Alexindo, another major player, boasts a production capacity of 27,000 tons annually and is known for its quality products used in prestigious high-rise buildings across Asia and beyond.
The Aluminum Extrusion Process
The extrusion process involves several key steps:
1. Die Preparation: The extrusion die is preheated to between 450-500°C to ensure uniform metal flow and extend its lifespan.
2. Billet Preheating: An aluminum billet is heated to 400-500°C to make it malleable but not molten.
3. Extrusion: The billet is loaded into the extrusion press, where it is pushed through the die under high pressure.
4. Quenching and Shearing: The extruded profile is cooled and then sheared to the desired length.
5. Stretching and Heat Treatment: The extrusion is stretched to correct any twists and then undergoes heat treatment to enhance its strength.
Detailed Steps of the Aluminum Extrusion Process
Step 1: Prepare Extrusion Die
The first step is to make a round-shaped die or use an existing one if available. Preheat the die to precisely 450-500°C before initiating the extrusion process. This helps ensure that the metal passes through evenly and maximizes the die's longevity.
Step 2: Pre-Heat Aluminum Billet
Next, a cylindrical billet cut from a stretched log of material is preheated in an oven to 400-500°C. This technique prepares the billet, making it malleable for operation without becoming molten.
Step 3: Move the Billet to the Extrusion Press
Transfer the billet mechanically into the press after preheating it. Lubrication is applied before filling the billet into the press, along with a release agent on the extrusion ram to prevent adhesion.
Step 4: Press-up Extruded Material Against the Die
The malleable billet fills the container's walls as it gets pressed against the extrusion die under high pressure. This pressure must be applied continuously until the extruded material emerges through the die opening fully formed.
Step 5: Quench the Extrusion
A puller grasps the extrusion after it exits the press. This puller safeguards it while undergoing a “quenching” process as it moves along a cooling table. The profile cools evenly through either a full water bath or fan cooling.
Step 6: Shear the Extrusion to Length
Once cooled to table length, use a hot saw to shear it. Temperature control remains crucial throughout each step of this process.
Step 7: Cool Extrusion to Room Temperature
After shearing, extrusions are moved from the runout table to a cooling area until they reach room temperature.
Step 8: Transfer Extrusions to Stretcher for Alignment
At this stage, any twists in shape need correcting using a stretcher. Each profile is held at different ends while being pulled until straightened according to specifications.
Step 9: Cut Extrusions to Desired Lengths
Once straightened and work-hardened, extrusions are cut into lengths typically ranging from 8-21 feet before being transferred for aging treatment (T6 or T5 temper).
Step 10: Perform Secondary Operations (Heat Treatment, Fabrication & Surface Finishing)
Upon completion of extrusion, profiles can undergo heat treatment for enhanced properties. Additional fabrication processes may correct dimensions or surface finishes improve aesthetics and corrosion resistance.
