Mastering Precision: The Steps of Closed-Die Forging at WALKSON

Introduction:

At WALKSON, our commitment to quality and precision in manufacturing steel parts is embodied in our closed-die forging process. Closed-die forging, also known as impression die forging, is a sophisticated method that ensures high-strength, durable components. Here's a detailed look at the steps we follow to create parts that are the backbone of industries worldwide.

Step 1: Material Selection

• Choosing the Right Steel: The process begins with selecting the appropriate steel grade based on the part's requirements for strength, wear resistance, and environmental conditions. Whether it's carbon steel for toughness or alloy steel for enhanced properties, WALKSON has the expertise to match the material to the application.

Step 2: Preparing the Dies

• Die Design and Manufacturing: Dies are the heart of closed-die forging. Our engineers design dies to exact specifications, ensuring they will produce parts with the desired shape, size, and features. These dies are then meticulously crafted to ensure precision and longevity.

Step 3: Billets Preparation

• Heating: Steel billets or bars are heated to a specific temperature, making them malleable enough for forging. This temperature varies based on the steel type, but it's crucial for achieving the desired grain structure and properties.

Step 4: Forging

• Pressing: The heated billet is placed between the dies. A forging press then applies force, causing the steel to flow into the die cavities, fully shaping the part. At WALKSON, we use advanced machinery to ensure consistent pressure for uniform density and quality.

• Flash: Excess material, or flash, escapes around the dies. While this might seem like waste, it's a sign that the part has been fully formed within the die.

Step 5: Trimming

• Removing Flash: After forging, the flash is removed in a trimming press. This step ensures the part has a clean, precise finish, ready for further processing.

Step 6: Post-Forge Treatments

• Heat Treatment: Depending on the part's requirements, it might undergo heat treatment to enhance strength, toughness, or wear resistance. Processes like annealing, quenching, and tempering are applied as needed.

• Machining: While closed-die forging provides near-net shape, some parts might require additional machining for final dimensions or to add features like holes or threads.

Step 7: Surface Finishing

• Surface Treatments: For additional corrosion resistance, aesthetics, or to meet specific performance criteria, surface treatments like shot peening, polishing, or coating might be applied.

Step 8: Quality Control

• Inspection: Every part undergoes thorough inspection at WALKSON. We use advanced techniques like dimensional checks, hardness tests, and non-destructive testing to ensure each component meets our stringent quality standards.

Step 9: Final Packaging and Delivery

• Packaging: Once inspected and approved, parts are carefully packaged to prevent damage during transit.

• Delivery: We ensure timely delivery, understanding that our clients' production schedules depend on our reliability.
