A continuous rolling process using wedge-shaped dies to form stepped, tapered shaft parts in a single pass without cutting waste, used in automotive, aerospace and machinery manufacturing.
Overview
In modern manufacturing, precise and efficient production processes are the core goals pursued by enterprises. Cross wedge rolling technology, as an advanced metal plastic forming process, is bringing revolutionary changes to the automobile, aerospace and machinery manufacturing fields with its unique technical advantages.
Key data
Full technical parameters are confirmed together with our engineers, based on your part and production volume.
Features
The cross wedge rolling process adopts a continuous rolling method, which can complete the production of large quantities of workpieces in a short time, significantly improving production efficiency. Material utilization rates exceed 90%, reducing raw material costs.
Through precise mould design and rolling control, cross wedge rolling achieves high precision and surface finish of the workpiece, reduces subsequent processing procedures and improves the overall quality of the product.
The process requires no high-temperature heating, reducing energy consumption and cutting waste.
Enables one-time forming of complex shaft parts such as stepped shafts and tapered shafts, reducing assembly procedures.
During the rolling process, the metal material undergoes plastic deformation, the internal structure becomes denser, and mechanical properties such as strength and toughness are significantly improved.
