100% of critical components undergo magnetic particle and ultrasonic testing. Our in-house metallurgical lab conducts chemical composition analysis, mechanical property testing, and metallographic inspection to issue full material certification reports.
One-Stop Solution from Raw Material to Precision Product
30 years of expertise, 10 production lines, and ISO-certified quality management system — delivering assembly-ready forged components with guaranteed precision.
Precision Forging Excellence
From raw materials to finished components, our 10-step manufacturing process ensures exceptional quality, precision, and reliability in every forged part we deliver.
Raw Material Preparation
Raw material preparation
The process begins with the selection of high-quality raw materials such as carbon steel, alloy steel, stainless steel, or aluminum alloy. Each batch is tested for chemical composition, cleanliness, and internal defects using ultrasonic inspection and spectrometer analysis.
Heating
Heating
Billets are heated in an induction or gas furnace to the forging temperature range, typically between 1000°C and 1250°C. Temperature uniformity is critical to prevent cracks and uneven deformation during forging.
Forging & Forming
Forging and forming
Once the billet reaches the correct temperature, it is transferred to the press or hammer for deformation. Depending on product type, open-die, closed-die, or precision forging may be used. Forging refines the grain structure and enhances strength and fatigue resistance.
Flash Trimming & Deburring
Trimming and deburring
After forging, excess material (flash) is removed using trimming dies. Burrs and edges are then ground off to ensure dimensional accuracy and smooth transitions between part surfaces.
Shot Blasting & Surface Cleaning
Scale removal & surface prep
Remove scale and oxide after forging & trimming to protect tools and reveal surface defects. Clean surfaces improve subsequent machining accuracy and coating adhesion.
Pre-Heat-Treat Machining (Roughing)
Establish datums & remove allowance
Perform necessary rough turning/milling/drilling to set machining datums, straighten features, and remove forging allowance. This reduces distortion impact during heat treatment.
Heat Treatment
Normalize / Q&T / Solution + Age
Apply controlled heat treatment to achieve target mechanical properties. Roughing beforehand minimizes post-HT stock and improves dimensional stability for finishing.
Non-Destructive Testing (NDT)
MPI / UT / PT
Conduct NDT after heat treatment to reveal quench-related cracks and internal defects before final finishing.
Finish CNC Machining & Final Dimensional Check
Tight tolerances after HT
Perform finish turning/milling/grinding to reach final tolerances (up to ±0.01 mm), followed by full CMM verification against drawings and CTQs.
Surface Treatment & Packaging
Surface treatment and packaging
Surface finishes such as zinc plating, black oxide, painting, or phosphating are applied per customer requirement. Parts are then rust-proofed, labeled, and packaged in export-grade cartons or wooden crates.

A professional forging parts manufacturer controls every stage — from material selection to final inspection — ensuring parts meet ISO 9001 and industry standards for durability and precision.
