Automobile Industry
Automotive brake pad back plates are important structural components in vehicle braking systems. Their production requires consistent dimensional accuracy, stable forming performance, and reliable material feeding, particularly when high-strength and thick steel coils are used.
To meet these requirements, YouYi Precision developed and delivered a heavy-duty 3-in-1 coil feed line for automotive brake pad back plate stamping. The system integrates decoiling, leveling, and servo feeding into one automated production unit and is designed for processing high-strength steel coils with material thicknesses up to 10mm. For this project, YouYi Precision supplied a customized heavy-duty configuration designed to process high-strength steel coils up to 10mm thick. Standard product configurations may vary depending on material width, yield strength, coil weight, and specific production requirements.
The solution combines a hydraulic expansion decoiler, coil loading trolley, heavy-duty straightening system, servo-electric adjustment, and precision servo feeding to provide stable material handling for demanding automotive stamping applications.
Automotive brake pad back plates must maintain consistent dimensions and forming quality because they are used in safety-critical braking systems.
As automotive manufacturers increasingly adopt high-strength steel, thick coil materials create additional challenges for conventional coil feeding systems. Heavy material weight, high yield strength, springback, and internal coil stress can affect leveling performance and feeding stability.
For this application, the customer required an automated coil feeding solution capable of handling 1.0–10mm high-strength steel while maintaining stable material flow during continuous stamping.
YouYi Precision therefore supplied a heavy-duty 3-in-1 coil feed line specifically configured for thick steel automotive stamping.
Before implementing the automated feeding system, thick high-strength steel presented several production challenges:
Heavy coils were difficult to load and position manually.
High-strength steel generated significant springback after decoiling and leveling.
Conventional leveling systems could experience insufficient leveling force when processing thick material.
Feeding instability could affect the dimensional consistency of stamped brake components.
Changing material specifications required additional mechanical adjustment and setup time.
Thick steel processing required a more rigid machine structure to withstand high straightening forces.
These challenges made reliable coil handling and precision feeding essential for stable brake pad back plate production.
The supplied system integrates three core functions into one production unit:
This integrated configuration shortens the material transfer path, reduces manual handling, and simplifies coordination between the coil processing equipment and stamping press.
The hydraulic expansion decoiler is equipped with a coil loading trolley and pressing arm to support safe handling of heavy steel coils.
The coil trolley assists with positioning the coil onto the decoiler, while the pressing arm helps control the material during unwinding. An adjustable limit arm allows operators to accommodate different coil widths and improve material alignment during production.
After leveling, the strip enters the servo feeding section and is accurately delivered to the stamping press.
Servo-controlled feeding enables programmable feed lengths and repeatable material positioning, helping maintain stable production when manufacturing automotive brake pad back plates.
By integrating decoiling, leveling, and feeding into one machine, the 3-in-1 configuration reduces the need for separate equipment and simplifies the overall stamping line layout.
This is particularly beneficial for automotive stamping workshops that require heavy-duty coil processing while maintaining an efficient production footprint.
The straightening section is one of the most important parts of this automotive stamping solution.
For processing high-yield-strength steel up to 10mm thick, the system uses a reinforced straightening structure with a 9-over-4 roller configuration and 110mm diameter rollers.
The large-diameter rollers provide increased contact and leveling force when processing thick steel strip.
The straightening rollers are manufactured from SUJ2 bearing steel and undergo hardening and precision grinding to improve wear resistance and dimensional stability.
The reinforced upper and lower frames provide the rigidity required for heavy-duty leveling operations and help maintain stable material flatness during continuous production.
A hydraulic shear unit at the outlet can also be used to cut the coil head and tail, helping reduce setup work during coil preparation and material changes.

Different steel grades and material thicknesses require different leveling settings.
The system therefore uses a servo-electric adjustment mechanism combined with a parameter memory function. Operators can store leveling parameters for different material specifications and recall the corresponding settings when changing production orders.
This reduces repeated manual adjustment and helps shorten setup time when the stamping line processes multiple material specifications.
For automotive component manufacturers, this provides greater flexibility when switching between different brake pad back plate specifications or other thick steel stamped parts.
A heavy-duty 3-in-1 coil feed line is particularly suitable for brake pad back plate production because it addresses several requirements simultaneously.
The reinforced leveling system helps stabilize thick steel before it enters the stamping press, while servo feeding provides controlled material positioning.
The hydraulic decoiler and coil loading trolley reduce the difficulty of handling heavy coils and improve the safety and efficiency of coil loading.
Servo-electric adjustment and parameter memory allow operators to quickly recall previously configured leveling settings.
Decoiling, leveling, and feeding are combined into one automated system, reducing manual material transfer and simplifying production-line integration.
Although this system was configured for brake pad back plate production, the same heavy-duty coil feeding concept can also be applied to other high-strength steel automotive components.
After implementing the heavy-duty 3-in-1 coil feed line, the customer achieved more stable coil handling and feeding performance during thick steel stamping production.
The integrated system reduced manual material handling and improved the consistency of material preparation before stamping. The heavy-duty leveling structure also provided the required processing capability for high-strength steel coils up to 10mm thick.
The servo-electric adjustment and parameter memory functions further simplified setup when changing material specifications.
As a result, the automated feeding system provides a reliable foundation for continuous production of automotive brake pad back plates and other thick steel stamped components.
The heavy-duty 3-in-1 coil feeding system can also be configured for other automotive stamping applications involving thick and high-strength steel, including:
Reinforcement plates
Suspension components
Structural brackets
Reinforcement beams
Other heavy-duty stamped automotive parts
The appropriate feeder configuration should be selected according to material thickness, material width, coil weight, yield strength, feeding length, and stamping press requirements.
The automotive brake pad back plate stamping case demonstrates how a heavy-duty 3-in-1 coil feed line can improve coil handling, leveling, and servo feeding when processing thick high-strength steel.
With hydraulic coil loading, a reinforced 9-over-4 straightening structure, 110mm leveling rollers, servo-electric adjustment, parameter memory, and precision servo feeding, the system provides a stable automated solution for demanding automotive stamping applications.
For manufacturers processing 1.0–10mm high-strength steel coils, YouYi Precision can develop and customize coil handling and stamping automation systems according to material specifications, coil weight, press capacity, feeding requirements, and production layout.
A heavy-duty 3-in-1 feeder line is designed for processing thick steel materials, including high-strength steel, carbon steel, and automotive structural plates with thicknesses up to 10mm.
A 3-in-1 feeder integrates decoiling, straightening, and feeding into one system, ensuring stable material flow, accurate feeding, and efficient production for automotive brake components.
The system is suitable for automotive brake pad back plates, chassis components, reinforcement parts, suspension components, and other thick steel stamped parts.
The equipment described in this case is configured for processing high-strength steel with thicknesses from 1.0mm to 10mm. Actual processing capability depends on material width, yield strength, coil weight, and other production parameters.
High-strength and thick steel generally requires greater straightening force because of its higher yield strength and springback. A reinforced leveling structure with appropriately sized rollers helps improve material flatness and feeding stability before stamping.
A 3-in-1 feeder combines decoiling, leveling, and feeding into one automated system. This can reduce manual material handling, simplify line integration, improve feeding consistency, and reduce the footprint compared with separate machines.
Besides brake pad back plates, heavy-duty coil feeding systems can be configured for automotive chassis components, reinforcement parts, suspension components, structural brackets, and other thick steel stamped parts.
Selection should consider material thickness, material width, yield strength, coil weight, coil dimensions, required feed length, stamping press capacity, and production speed. YouYi Precision can customize the coil feeding system according to the customer's specific stamping requirements.
