Precision Progressive Die Manufacture
The Fine Blanking advantage
Fine Blanking is a specialized form of stamping used to produce high-precision parts with clean-cut, straight edges with a high degree of reliability and repeatability. The use of higher pressures and additional forces means that more operations can be carried out in a single die with higher dimensional accuracy. Fine blanked parts with complex shapes involving forming can therefore be produced in shorter and more cost-effective production cycles and with reduced incidence of secondary operations like machining or re-striking for flatness. The parts produced by us are an example of these multiple advantages.
Our Stamping operations are geared to produce parts in thin (<0.5mm) and thick steel (6 to 9mm), with a variety of shapes and features and across applications like Braking, Chassis, Steering parts for 4 and 2 wheelers and Tractors. The operation is designed to be flexible and cost competitive, also in medium and low volume situations, and uses stage as well as progressive die technology.
1. Clean-cut and Straight Edges
The combines action of three forces during blanking results in finished edges superior to conventional stamping process.
The nature of the material holding and cutting action results in a high level of flatness, eliminating added operations like re-striking.
3. Multiple features within the tool
Progressive tools and additional force make multiple operations, such as coining, forming and bending, possible in a single tool. This means reduced machining costs and shorter lead times for large production runs.
4. High strength and Wear Resistance
Flat rolled steel of varying tensile values are used to product fine blanked parts and the combination of the blanking, counter and V-ring forces imparts higher wear resistance to the cut edges.
5. Positional accuracy and high-volume consistency
Fine blanking is ideal for keeping tight tolerances across high-volume production bathes. Small holes in relation to material thickness can be pierced close to the edges of the part.
