Product Description
Yile Machinery is a specialist in manufacturing high-strength, custom-forged components using the closed die forging process. Also known as impression die forging, this method is ideal for producing parts that require superior mechanical properties, dimensional accuracy, and consistency across high-volume production runs.
We transform raw steel billets into complex, near-net-shape parts that are stronger and more reliable than their cast or machined equivalents.
Closed die forging confines a heated metal billet between two custom dies that contain a negative impression of the final part. The immense pressure forces the metal to flow and fill the die cavity, refining the grain structure and aligning it to the part's shape. This results in:
1.Superior Strength & Fatigue Resistance:
The uninterrupted grain flow creates exceptional strength, ductility, and resistance to impact and fatigue. Forged parts are significantly more durable than cast or machined parts.
2.Near-Net Shape & Reduced Costs:
The process produces parts that are very close to their final dimensions, drastically reducing material waste and subsequent machining time, which lowers the overall cost per part.
3.High Consistency & Repeatability:
The use of robust, reusable dies ensures that every part, from the first to the last, maintains tight tolerances and dimensional consistency.
4.Elimination of Internal Defects:
The forging process consolidates the material, eliminating internal porosity, voids, or shrinkage that can be found in castings.
We offer a complete solution from tooling to the finished component.
Step 1: Tool & Die Engineering: We design and manufacture high-precision forging dies based on your part drawings.
Step 2: Billet Heating: Steel billets are heated to the optimal forging temperature (typically 1100°C to 1250°C) in an induction furnace.
Step 3: Forging Operation: The hot billet is placed in the bottom die, and a forging hammer or press forces the top die down, shaping the part.
Step 4: Trimming, Heat Treatment & Machining: The "flash" (excess material) is trimmed off. The part then undergoes heat treatment (e.g., quenching, tempering) to achieve the desired hardness and mechanical properties, followed by final CNC machining if required.
We have extensive experience forging a wide range of ferrous metals:
Alloy Steels: 4140, 4340, 8620 (for high-stress, high-wear applications)
Carbon Steels: 1045, 1050 (for strength and general engineering)
Stainless Steels: 304, 316, 410 (for corrosion and heat resistance)
Our forged components are critical to the performance of machinery in many sectors:
Construction & Mining: Excavator teeth, track links, connecting rods, gear blanks.
Automotive: Crankshafts, control arms, yokes, and transmission components.
Oil & Gas: Flanges, valve bodies, and fittings.
Agriculture: Driveline components, tractor parts, and implements.
Railroad & General Industrial: Couplers, hooks, and machinery parts.
