In metal fabrication, punching and shearing are two distinct metalworking procedures. Metal punching is a cutting technique in which the material is removed from a metal sheet by exerting sufficient tearing power. On the other hand, metal shearing removes excess material from sheet metal without using heat or generating waste in the form of chips.
Punch and shear processing devices are metal fabrication machines that combine the functionalities of punching and shearing equipment. Typically, they are used to cut shapes and punch holes into metal sheets simultaneously.
In this article, we will take a deeper look at one of AIM Joraco’s projects which focuses on punch and shear applications.
AIM Joraco’s Punch & Shear Application Using Servo-Driven Feeder
AIM Joraco designed and constructed a highly automated multi-press punch and shear system to produce transformer core sheets. The project’s objective was to achieve precise tolerances of 0.002 in. around the burr of the punched hole in the steel sheet. Moreover, the client generally used the system in electrical transformers.
Engineers designed, fabricated, and rigorously tested the punch tools to ensure dimensional accuracy in the stack core transformer design for the client. Various in-house tests were also conducted to confirm that the tools consistently generated holes of the desired size and shape.
AIM Joraco delivered this automated fabrication technology with a set of carbide tools that we precisely honed. Due to carbide’s ability to keep its cutting edge even during high-speed punching, the tooling achieves exact tolerances and delivers accurate components during long production runs.
Capabilities Applied and Processes
To achieve the exact tolerances required, AIM Joraco applied the following processes:
Punching: Metal punching stamps a shape onto a surface via pressure or percussion using a steel punching tool. This method removes material from a metal sheet by exerting sufficient cutting power.
Shearing: Metal shearing cuts through a metal sheet using a blade attached to a tool or machine. A squaring arm controls the placement of the cut, allowing a metal sheet to be placed in a precise area.
Servo Feeding: The servo feeding process uses a machine motor that powers the feed roller via a synchronous belt wheel. It also utilizes the release signal supplied by the punch cam to discharge the generated error through the cylinder.
Equipment Used To Manufacture and Overall Dimensions
The following machines and devices are used to fabricate the multi-press punch and shear system:
2x Toggle Aire 2530 Press: The Model 2530 Press from AIM Joraco has a repeatability of 0.001 inches and can cycle up to 80 strokes per minute — faster cycle times with shorter-than-standard strokes.
Carbide Tooling Package: The precision-sharpened carbide tooling package enabled the system to create accurate components across extended production runs while preserving its cutting edge.
Servo Motor: A servo motor is a rotary or linear actuator that permits exact control of position, velocity, and acceleration. It consists of an efficient engine coupled with a position feedback sensor.
The overall part dimensions of the system are 29.5 in. (width) x 30.75 in. (depth) x 63 in. (height).

Powder compaction is gradually becoming an essential industrial manufacturing technique for producing components with complex shapes and structures. It is the process of tamping powder particles in a die using high pressures. The tools are typically held vertically, with the punch tool forming the bottom of the chamber. After that, the powder is compacted into a shape and ejected from the cylinder.
A powder compacting press compresses granular and powdered raw materials into various standard and custom-shaped units. It can suppress a wide range of products with high product density specifications and can compact multiple pieces at once, making it ideal for large production industries. In addition, the press requires innovative integrated machines, electricity, liquid, and gas control, as well as an automatic feeding and discharging device.
This article will discuss the different types of powder compacting presses and the product developed by AIM Joraco.
Types of Powder Press Machines
The four most common types of press machines used to compact powder material are as follows:
A hydraulic press generates compressive force by using a hydraulic cylinder. It is appropriate for the industries of carbides, powder metals, ceramics, polymers, and other particulate materials. Furthermore, hydraulic presses are commonly used in factories that manufacture powder products.
Mechanical presses are frequently used in manufacturing technical ceramics, but they are also well-suited for other commercial processes. Compared to hydraulic press machines, mechanical powder presses have limited maximum compaction forces that are typically greater than or equal to 5000 kN.
Electric powder presses are servo-powered machines that compress materials at extremely high pressures. Because of their servos, they can regulate the placement and response time of the output shaft instead of keeping a constant press cycle speed. Moreover, electric metal presses can perform several functions and use a closed-looping feedback mechanism to enable a more precise cycle rate and load regulation.
Isostatic presses enable users to produce uniform-density components using a dry bag design, simplifying and improving powder filling, compaction, and ejection. These machines are typically used in ceramics, carbides, composite materials, pharmaceuticals, and explosives.
AIM Joraco Compacting Press
AIM Joraco developed a compacting press for the world’s leading provider of technology for the oil and gas industry. It is the outcome of the need to design an explosion-proof mechanism with an integrated safety capacity. It must also adhere to industry standards, legal requirements, and the company’s clear and specific guidelines.
The company designed and built this compacting press entirely in-house. This included reinforced machine guarding, a robust protection system, integrated safety features for operators and equipment protection, and a process control system for capsule consistency.
The following are features highlighted in the developed compacting press:
Compacting: The press is intended to pack explosive substances into capsules for oil well-perforating processes.

How Does the Assembly System Work?
This assembly system features two 8-ton AIM Joraco Hydro-Aire® presses, a rotary electric motor mounted on top of a pneumatically powered linear slide, and an optical sensing system.
As the operator activates the system and loads the hub into the press with loosely inserted pins, the linear slide moves the wheel into position. Next, the optical sensors guide the electric motor as it rotates the wheel hub until one bolt is accurately located under each press. The presses then activate simultaneously with precise force to insert the perfectly aligned bolts into the hub. Once that is done, the motor moves the succeeding two bolts into position, and the process repeats until every bolt is in its place. Lastly, the part is manually ejected after the slide retracts.
AIM-Joraco Wheel Hub Assembly Machine
AIM-Joraco constructed the assembly machine by incorporating two of its HP8 Series Hydro-Pneumatic Presses into a custom-built press frame. As a result, the machine takes up only 7.5 square ft. of floor space, with a footprint of 45 in. long x 24 in. wide. A safety light curtain has also been installed to protect operators from machine motion injuries.
PLC Control Unit provides control and logic verification to ensure the bolts are pressed to the correct depth and that all the bolts are processed.
Linear Slide System then shuttles the finished hub assembly to allow the operator to remove and repeat the process.
Press Fit Bolts: These are used to connect flange couplings.
Rotational Positioning: During installation, the bolt is positioned in the coupling holes in a clearance condition, and the sleeve expands by drawing the bolt through the sleeve to provide a proper interference fit.
Optical Sensing for Positioning: Position sensors detect movement or determine an object’s perceived position relative to a known reference point.
Equipment Integrated into Solution

When cutting a particular shape from a material, die-cutting makes the process more efficient and accurate than cutting by hand. Die-cutting uses a die and a machine to cut, which produces more consistent results in less time, making it great for a variety of applications. Due to die-cutting’s ability to cut intricate shapes from paper and other materials, it’s frequently used for the fine arts and medical industries.
Using Die-cutting Machines
A die-cutting machine is used to cut custom shapes from different materials, including paper and vellum. The machine consists of cutting plates and rollers, which apply pressure to a die to press it through the base material, creating the desired shape. Using a custom die featuring nearly any shape imaginable, you can cut the same shape repeatedly with more efficiency and minimal risk of mistakes.
There are two main types of die-cutting machines available: manual or digital die-cutting machines. Digital machines, which often use laser technology to complete die cuts, connect to computers. Designs are cut either from scratch or designs created in software. Laser die-cutting machines offer more accuracy, precision, and efficiency than other types of die-cutting machines.
Cleanrooms provide a controlled environment with minimal exposure to contaminants. They are used in a variety of industries where dust and debris, microorganisms, chemical vapors, or aerosolized particles might impact the efficacy of a process or product. Selecting equipment designed for use in cleanrooms is critical for maintaining the sterilization and cleanliness standards of the environment.
WHAT LEVEL OF CLEANROOM DO YOU HAVE?
Cleanroom levels vary depending on the needs of the application. The requirements for each class of cleanroom are determined by ISO 14644 standards, as well as corresponding FED STD 209E standards. These guidelines set specific rules regarding the number of particles that can be present in the cleanroom’s air supply, as well as the size of those particles. ISO Class 1 has the highest purity standards, while ISO Class 9 is roughly equivalent to the air quality of standard rooms.
At AIM Joraco, we offer pneumatic presses for use in cleanrooms. We have three levels of pneumatic press available to suit varying cleanroom levels:
Level 1 (Cr-1)
· Exhaust air cleanliness: Equivalent to ISO Class 5 (FED STD Class 100); particles of 0.3 µm or larger (3.5 particles/ℓ or less)

At AIM Joraco, we are pleased to offer the highest quality precision pneumatic and toggle presses, rotary indexing machines, and fabrication tooling for a wide range of applications. Our toggle presses offer superior accuracy and reliability, so you can be sure that your manufacturing and assembly processes are running as smoothly and efficiently as possible without the mechanical complications common with hydraulic and power presses.
WHAT IS A TOGGLE PRESS?
A toggle press is a metal fabrication tool used to bend or indent metal stock or sheets. Rather than using electrical power, a toggle press relies upon pneumatic power to exert force through a series of strategically placed levers.
The mechanism consists of toggle lever connected to a secondary toggle, which manipulates the compressing piston by pressing it downward into flat material fastened to the press table. The use of toggles significantly increases the pressure placed on the material by multiplying the force. As such, toggle presses often exceed the available force of other common bending methods such as hammer striking. Incorporating pneumatics into the system enables an exponential increase in available force, significantly increasing pressure while reducing manual strain on operators.

Pneumatic presses offer a range of benefits in a wide range of applications. These machines are great due to their:
Pneumatic presses generate a force greater than manpower( manual press usually known as an arbor press) alone can supply. It can be used for pressing, squeezing, forming, and other actions. Removes the potential for repetitive strain on the operator, increases efficiency, and pressing repeatability resulting in better quality parts and reducing costs over time.
HOW DOES A PNEUMATIC PRESS WORK?
The potential force of a pneumatic press comes from compressed air pressing against a piston inside an enclosed cylinder, The area of the piston multiplied by the air pressure determines the force generated by the press. The actuation of the press comes from either an air or electric signal, typically generated by an operator when running manually, or by a PLC in an automated system setup. The signal to the press can be configured to create a complete cycle for each signal sent. It also can be configured for Constant Signal Required (CSR) whereby the operator is required to maintain the input signal for the press to actuate, staying down, applying force until the operator removes the signal, then the press would retract. Operators typically use an anti-tie down controller which requires two hand operation to insure the operator’s hands are free from the work area and potential risk of injury. PLC actuated systems utilize sensors and physical/light curtain guarding to insure operator safety.
Direct double acting pneumatic presses are the most widely used type in industrial applications. These types of presses use air to advance and retract the cylinder, which is beneficial for applications with heavy tooling attachments, and applications that require quick response and cycle times.
DIFFERENCES BETWEEN HYDRAULIC (MECHANICAL) & PNEUMATIC PRESSES
There are several key differences between the pneumatic press and hydraulic presses.
Method of Operation
Hydraulic presses function similarly to the principles of the pneumatic press. However, instead of compressed air, the driver for their movement is a fluid base.
Pneumatic presses do not require much in terms of maintenance.
If there is a leak, then only air escapes, which can be easily replaced once the leak has been repaired.
Conversely, if a hydraulic machine leaks, it loses fluids, which creates a mess that requires time to clean up.
Pneumatic presses operate at very high speeds, whereas hydraulic presses operate at much slower speeds.
A GUIDE TO PNEUMATIC PRESS SAFETY
Employee safety is the most crucial component of every industrial setting. Therefore, it’s important that you properly train your employees and operate each piece of equipment with care.
Below are some pneumatic press safety tips that any shop using a pneumatic press should follow.
Release all compressed air.
Whether the pneumatic press is shut down, undergoing maintenance, or merely inactive, it’s critical that the compressed air in the machine is released correctly.
Every pneumatic press should have a release valve (labeled “lockout/tagout”). This valve will safely and effectively release all compressed air back into the environment.
Failure to release air properly can result in serious injury to employees.
Restrain all tubing.
Tubing is overlooked in shop settings. However, pneumatic press tubing has the potential to cause injury if snapped or broken.
To mitigate this risk, group bundle/bond all tubing.
Like any shop machine, adequate training is critical towards reducing potential injuries. It’s crucial that all employees are trained to industry standards on any new or old machine the shop.
Again, like all other machines in the shop, performing regular risk assessments on your press can lower potential safety hazards.
BASIC TROUBLESHOOTING FOR YOUR PNEUMATIC BENCH PRESS
If you own a pneumatic bench press, troubleshooting potential problems is typically quick and strait forward. Referring to schematics, pneumatic have three basic components: The air cylinder, the power valve, and the signal source(actuator).
To obtain an accurate diagnostics, the best course would be to contact your pneumatic bench press manufacturer to diagnose and assist with fixing the problem.
In the meantime, here are a few steps you should take to diagnose and troubleshoot common problems associated with your pneumatic presses.
Do you hear any leaks in the system? First and foremost you want a have an air leak free setup. When the air supply is turned on be sure your hands are away from the pressing area.
When you operate the actuator, does the press cycle? If not, remove the signal out from the actuator and try to cycle to see if signal is present. IF not, the actuator may need repair/replacement. If the press is going down but not generating full force, check you air supply line to confirm adequate pressure is supplied to the press. If the press is not properly maintained and lubricated, it is possible you need to replace the seals and o-rings in the cylinder.
What do you use your press for?
If you work in clean room environments, such as medical device manufacturing and aerospace, pneumatic presses can be configured to be compliant to Class 100 Clean room particulate compliance. Utilizing stainless steel construction and air particulate filtration systems, clean room pneumatic presses have many advantages in these types of applications. Clean, efficient, quiet, ease of use, and trouble free; pneumatic presses have flexibility and functionality to meet your needs.
If you have an application running small production runs, but need accuracy, repeatability and ease of operation, the pneumatic press is well suited to offer a quick, flexible and cost-efficient solution configured for manual operations.
For applications with higher volumes, longer run times, or secondary processes, a pneumatic press solution that includes PLC controls is easily configurable. Pneumatic presses can be setup with end of stroke sensors to provide feedback to the PLC to insure the press reaches bottom of stroke to perform the work, and top of stroke to know when the press has completed the operation. PLC working with other inputs can provide for an effective automated solution while maintaining cost-effective, low maintenance production.
Your press should have come with a handbook or other form of documentation regarding troubleshooting.
They will often come with diagrams, showing the correct placement of certain valves, grippers, and pressure settings.
If any of these seem as if they are out of place, try adjusting them before trying other troubleshooting options.
Inspect while you use the machine
If there are no apparent problems when your machine is not in operation, perform a visual inspection while the machine is operating.
You should look for signs of air leakage, drastic changes in system pressures, and any faults when the system moves.
You might have to get the help of a colleague or a friend to stay safe while the machine is in operation.
With a pneumatic bench press, one issue may be causing smaller issues elsewhere.
While some pneumatic hand press machines or other types of press may require simple lubrication or part replacement, it is essential to consult a professional when you make any major changes to your machine.
If a malfunction in your pneumatic press has been resolved, be sure to record where and when the incident took place to ensure you’re keeping an accurate log. This will be useful in the future if any other problems may occur.
