The production of OEM forging parts involves several critical steps from design to delivery. Each step is important for ensuring that the final part meets the required quality standards and performs as expected in its intended application. Effective collaboration between the manufacturer and customer is key to producing high-quality OEM forged components.
Read MoreOEM (Original Equipment Manufacturer) forging parts are custom-designed and produced components for specific applications, usually based on customer specifications. The process of producing OEM forging parts typically follows a set of key steps.
Customer Requirements: The first step is to gather detailed requirements from the customer, including the part’s dimensions, material specifications, strength, surface finish, and other mechanical properties.
CAD Modeling: Using computer-aided design (CAD) software, engineers create detailed models of the forging parts, taking into account all the physical constraints and intended use.
Die Design: Dies are designed and crafted to form the part shape. The die design includes considerations for the part's complexity, material flow, and draft angles for easy removal from the die.
The appropriate material is selected based on the part’s end-use application, mechanical properties, corrosion resistance, and other factors.
Common materials used for forging include carbon steel, alloy steel, stainless steel, titanium, and aluminum alloys.
Billet Cutting: A metal billet, which is a piece of metal stock, is selected based on the part's size and material. It is then cut to the correct length or weight.
Heating the Billet: The billet is heated to a temperature that makes it malleable but still strong enough to be shaped. The heating process is crucial to prevent the material from cracking or becoming too brittle.
Closed-die Forging: The heated billet is placed between two dies that contain the shape of the final part. The die is closed around the billet, and a hammer or press applies force to deform the billet into the desired shape.
Open-die Forging: In some cases, open-die forging is used for simpler shapes or for larger parts, where the material is shaped by the movement of the dies without completely enclosing the workpiece.
Upset Forging: This is another forging method in which the billet is compressed in the direction of its length, increasing its diameter.
Trimming: After the part is forged, excess material (called flash) that overflows from the die cavity is trimmed off.
Flash Removal: Flash, which forms around the edges of the die during forging, must be removed to ensure proper finishing and prevent the part from being oversized.
Heat treatment processes such as quenching, tempering, or annealing are applied to the forged parts to adjust their mechanical properties (strength, hardness, and ductility) to meet the customer's specifications.
Quenching: Rapid cooling to harden the material.
Tempering: Reheating to a lower temperature to relieve internal stresses and adjust hardness.
Annealing: Softening the material for better machining or forming.
Machining: Some forged parts require additional machining to achieve the desired surface finish, tolerances, and geometric features.
Surface Finishing: Processes like grinding, polishing, or coating may be used to improve the surface quality of the parts.
Inspection: The parts are checked for dimensional accuracy, surface defects, and mechanical properties using tools like micrometers, calipers, and testing machines.
Visual Inspection: Checking for surface imperfections such as cracks, burrs, or voids.
Dimensional Inspection: Ensuring that the forged parts meet the specified dimensions and tolerances.
Non-Destructive Testing (NDT): Techniques like ultrasonic testing, X-ray, or magnetic particle inspection may be used to detect internal defects.
Mechanical Testing: The parts are tested for tensile strength, hardness, impact resistance, and other performance properties based on the customer’s specifications.
After passing all inspections and quality control checks, the forged parts are cleaned, packaged, and prepared for shipment to the customer.
Parts are often carefully packed to prevent damage during transportation.
The OEM forged parts are delivered to the customer, and any necessary documentation (such as material certificates or test reports) is provided to ensure the parts meet all specifications.
