Forging Defect Diagnosis: Tracing Cracks, Folds, and Trim Faults Back to Die Design or Operation
When a forged part shows up at inspection with a crack, a fold, or a ragged trim edge。
继续阅读锻件流线方向对服役性能的影响｜Forging Flow Lines and Their Effect on Service Performance
Fibre flow is forged into the part, not added later. Bend it the wrong way and the strongest direction never meets the load. How flow line orientation decides where a forging fails.
继续阅读锻件晶粒度控制：终锻温度是关键变量｜Grain Size Control: Finishing Temperature Is the Key Variable
Grain size on a test report is decided in the last seconds of forging. Why finishing temperature outranks deformation amount, and how to hold it.
继续阅读模锻斜度与圆角对模具寿命的影响｜Draft Angles and Fillets: The Quiet Drivers of Die Life
Half a degree of draft and one millimetre of fillet radius move die life more than die steel grade does. Where the numbers come from and how to negotiate them.
继续阅读镦粗工艺的高径比与质量控制｜Upsetting: Height-to-Diameter Ratio and Quality Control
Upset a billet too tall and it bows and folds at the waist. Why the 2.5 to 3 rule exists, what end-face condition does to it, and how to save borderline cases.
继续阅读锻造比对锻件力学性能的影响｜Forging Ratio and Its Effect on Mechanical Properties
More forging is not always better. How forging ratio shapes fibre flow, anisotropy and mechanical properties, and where the optimum sits.
继续阅读闭式模锻与多向模锻工艺路线选择｜Closed-Die vs Multi-Directional Forging
Closed-die saves material, open-die forgives weight error, multi-directional makes the shape possible. Which route actually fits your part?
继续阅读锻件错模、飞边超差原因与模具对中管控｜Die Misalignment and Flash Control
A dimensional reject usually points at the die, but the real cause is often how it was mounted. Where does misalignment start?
继续阅读锻件脱碳层控制工艺与加热气氛管控｜Forging Decarburization Control
Surface carbon burns away long before the forging looks wrong. How deep does decarburization run, and what machining allowance covers it?
继续阅读锻打批次工艺参数标准化管理｜Standardising Process Parameters Across Forging Batches
When each shift sets its own parameters, the same part comes out different every batch. What belongs on the process card, and who is allowed to change it?
