Brief Profile of Press Feeding Line

The Press Feeding Line is an advanced machine designed to supply coils of material to a power press for efficient production of various products. Its compact design is especially suitable for customers with limited space. It offers process reliability, even for the most demanding materials, making it ideal for manufacturing structural parts and processing high-strength materials, including the higher ranges of strip thickness.

The principle of the press feeding line is that the motorized Decoiler (Coil Reel) with drive continually moves the strip into a bottom coil loop, supplying the Straightener-feeder, which then feeds the coils strips into the power press machine.

Our MFL5 series press feeding line can handle material strips up to 2000mm stock width and approximately 9mm thickness, with coil loading capacity up to 25 tons.

The Decoiler Straightener Feeder Press Feeding Line is widely used in the auto parts industry, hardware stamping industry, home appliance industry, electric appliance industry, and other related fields. Its high efficiency, reliability, and precision make it an essential machine tool in modern manufacturing processes.

Features of Press Feeding Line

● Advance Techniques

With the world’s leading automatic press techniques ,advanced and humanized management system,we unite thousands of elites dedicated to the development of automatic press,including top engineers in this field,experienced technicians, production workers with fine craftsmanship to ensure every equipment produced durable ,high-efficiency and stable.


● Modular control, simple and smart operation

Compact coil feeding machine is not only a simple combination of decoiler, straightener, and feeder machine into one unit, but also highly integrated control in operations. The hydraulic station, coil car, uncoiling motor, spindle and inverter, straightener part, servo feeder motor are connected with the PLC modular system and controlled by one touch screen, which is quite convenient and easy for operators.

Moreover, movable regulating handle is very convenient operation for installing and debugging when the machine is testing.


● Reliable Structure Design

Super large scale and plenty of advanced quality control measures including CNC machining, grinding machine, boring machine and Lathe machine equipment and various precision testing instruments from Germany, Japan and Taiwan. It can ensure the high precision and quality of all parts of machine.

What's more, all of main body makes surface treatment with our shot blasting machine before they are painted. With our shot blasting machine treatment, the machine surface is excellent for painting.they blast onto the surface of work piece with shots to clean and beautify the surface. The shot blasting also enhances the pressure stress of work piece surface and extends the lifespan.We also use high-end vehicle oil paint for our machine to have high level of painting quality and you don’t need to worry about broken painting problem under extremely nasty working environment. 


● High precision straightening and feeding performance

The metal coils trips will be inserting into straightener-feeder part automatically after uncoiling, with photoelectric sensors for full closed loop control, no manual operation. The straightener roller and feeder roller mechanism are placed on the same precise platform to ensure the uniformity of parallel precision and to limit the error of leveling and feeding operation to the maximum extent.


● Wide range of metal coil stamping application

The high strength coil feeding line is not only suitable for normal material with thick thickness, but also can handle high strength material. It can deal with steel thickness up to 12mm coil width up to 1800mm with high precision straightening performance. Compact coil feeding line is ideal for the high strength material steel stamping in automotive,construction and electrical appliance industry manufacturing.


● Space-saving, easy installation and maintenance

Compact design is ideal for limited space workshop.  

The compact coil feeding line is very easy to install, which can enter into mass production in a short time. Without a long material loop, the coil feeding line length is usually no more than 5m, some models such as MFL2 is only 3m length, which will save workplaces of stamping room. Thanks to the international brand core components, automatic lubrication system and self-inspection procedures, the compact coil feeding line have a very low failure rate and easy to maintenance

Main Parts of Press Feeding Line

Coil Car

Coil Car

● Coil car has two function, one is assisting loading the coils on the spindle of decoiler parts, other is leading the uncoiling strips into the straightener-feeder parts.

● With the coil Car auxiliary loading, the operator can safely and conveniently for loading coils,when used for operation, the material coil is transferred to the mandral rack spindle smoothly.

● The coil car is equipped with the material coils anti-dumping baffle, which can effectively prevent the material coil from dumping when transferring materials with small material width.

Decoiler Machine

Decoiler Machine

● After the coils holds on the spindle of decoiler machine, decoiler machine rotates intermittently to release the metal coil to metal strip, the support rollers on coil car will lead the strips into the straightener arm.

● Decoiler with support cantilever structure can loading up to 25ton. And there’re three groups of hydraulic wedged structure for uncoiler spindle expansion. 

● Moreover, Material auto-alignment function as an optional meet your requirements.

Coil Inlet Support Arm

Coil Inlet Support Arm

● After uncoiling process, the support rollers on the coil car will lead the material strips to coil inlet support arm which is driven by a hydraulic cylinder will close automatically to hold-down material strip when strip head touch the straightener part.

● The bottom inlet roller is geared transmission, sharing drive power with straightener rollers.

● When upper inlet roller goes down, the two rollers clamp the metal strip and lead it to the straightening part.

● These two rollers are made by high quality bearing steel, with sandblasting treatment, hardness reaches HRC60±2.

High Precision Straightening and Feeding Machine

High Precision Straightening and Feeding Machine

● The straightener feeder parts leveling the coil strips and feeding it into the stamping press and dies according to the fixed length controlled by PLC.

● Given the difference in coil at the beginning of rollers and the end of roller, it is usually necessary for an operator to always be monitoring straightening operations, and to manually carry out corrections to ensure a high degree of precision in straightening. With the unique electrically adjustment fitted on the MFL4-GF Series coil straightener-feeder, changes in the coil strips thickness are detected during production. Straightening correction is performed continuously and automatically. it making a significant contribution to operational efficiency.

● Moreover, additional backup roller can achieves a high precision straightening performance.

Discharging Support Bracket

Discharging Support Bracket

● The outlet support bracket is used to deliver the straightening strips to press die smoothly.

● When the coil material is thin thickness or soft material , or the distance between straightener-feeder and stamping dies is long, the strip can not be delivered the strip head into the die successfully, the support bracket will be help to reach it.

● The length of the support bracket is adjustable to meet different dimensions of stamping press machine and dies.

Hydraulic shearing machine (Option)

Hydraulic shearing machine (Option)

● A hydraulic shearing unit is used to cut the material heads and tails for productivity improvement and better stamping product quality.

● The hydraulic cutting unit has four sides scissors to achieve smooth cutting.

● It's operated by touch screen control and with manual scissors adjustment.

Automatic Lubrication Unit (Option)

Automatic Lubrication Unit (Option)

● Lubrication of steel strip before stamping will protect the stamping dies from damaging and prolonging the uselife.

● The automatic lubrication system is automatically controlled, with an oil loop recycling system, which will save oiling cost and prevent leakage.
