How Custom Sheet Metal Increases Your Profit

Sheet metal is a flattened piece of metal that is used extensively in the electrical and manufacturing industry. Sheet metals can be made out of various metals or alloys such as aluminum, steel, copper, brass to name a few.

To make the best use out of sheet metal, they are fabricated using various cnc machining processes such as cutting, punching, welding and bending. Fabrication also helps to keep the manufacturing cost low, the quality of material great and production on a large scale.

Customizing a sheet metal helps to fulfill the objective of designing pieces of metal as per the desired industrial requirement. Since the designs are precise, they facilitate large-scale production with uniformity and without compromising on quality. The products made using these custom sheet metal designs can also be used at a later stage to modify or repair the existing product, thereby increasing longevity and minimizing loss.

Sheet Metal Customization Methods

QBH technology and other kinds of methods are used to customize the metal sheet as per the requirement.

Cutting

Cutting is one of the most basic methods to customize a metal sheet. Metals can be cut by sawing, shearing, using a high pressure water jet, etc to customize the sheet metal as per the specific requirement.

Bending

Bending is achieved by subjecting the metal sheet to hydraulic brakes that are set at certain angles. The metal sheet is then placed in the brakes and applied force to bend it at the specified angles.  

Rolling

Rolling is either done using a hot-rolling process or a cold-rolling process. The hot-rolling method is used to create thin metal sheets whereas the cold-rolling method is used to make thick metal sheets.

Welding

Welding is an important method to customize a metal sheet. Once the desired shape is attained, welding helps to retain that shape of the metal so that it does not get deformed.

Shrinking and Stretching

Shrinking is done to smoothen out the edges and other irregularities in the shape of the metal. Stretching on the other hand is done to stretch a metal sheet and get the desired shape.

Fastening

Holding tools like nuts, screws, etc are used to hold the metal sheet tightly during the customization process.

Hydroforming

Hydroforming is a method in which the metal sheet is subjected to high pressure fluid to give it the desired shape.

Punching

Punching is done to give the metal sheet a uniform shape throughout and remove any holes in the sheet.

Assembling

Assembling is often the last step of customization and is achieved by welding, binding and bending to get the desired outcome.

How Custom Sheet Metal Increases Profit?

Be it the automotive industry, electrical industry, utility industry, medical industry, or even agricultural industry for that matter, companies often prefer a custom metal sheet that perfectly suits their production requirement. Sheet metal can be cut, punched, bent, stamped, welded, rolled, cnc machined, drilled to get the customized output.

A custom metal sheet helps them to scale up production at a low cost as there are fewer to no manufacturing challenges and the output is precise. Furthermore, companies can keep being innovative and create better designs as they know they can completely rely on custom sheet metal to replicate the designs.

Durability

Choosing the right kind of metal and giving it the right thickness, a customized sheet of metal increases the lifespan of the parts to a great extent. Add to that the property of metal sheets being corrosion, heat and rust-free and you get more out of your products than the set target. A great reason to shift to a custom sheet metal approach.

Fewer Limitations More Productivity

There is no limit or restrictions when it comes to customizing a metal sheet as per the design requirement. The entire process of customization through cutting, drilling, welding, etc takes less time thus enabling a higher rate of production at a low cost. Furthermore, this can be achieved using any kind of metal thus providing the company’s flexibility to choose from the metal suiting their manufacturing requirement.

Faster Turnaround Time

With the usage of QBH technology and other automation tools such as cnc machining, it is now possible to customize sheet metals with great precision in less time. This feature enables companies to roll out products quickly into the market and meet the growing demands of their customers.

Ease of Transport

Custom-made sheet metals can be customized in such a way that their weight is less as compared to a non-customized metal sheet. This option makes it easier to transport such metal sheets.  

High Precision

The process of customizing a metal sheet can be streamlined to get the same output again and again with great accuracy and precision to suit the specific requirements of the industry. Thus companies no longer need to remain stuck with standard designs, instead, they can use custom designs and meet the market requirements at ease.

Easy Repair

More often than not, after say, 10 years or so old equipment tends to become of no use. This does not hold true for custom sheet metals since they can be easily re-engineered and be of use again. The old custom sheet metals can also be easily recycled thus they are environmentally friendly.

So in totality, adapting to using custom sheet metals is not at all a complex process. It is very much viable and makes absolute sense, now that all the cnc machining tools and other automotive methods are in place. The shift to custom metal sheets will give you the flexibility and the license to go for the kill and carry out large scale production that is bound to give you great benefits and greater results.

Thus, those companies looking to bring their production in line with the market demands, those who wish to innovate in terms of design, those who want to be a leader in the manufacturing space and bring new efficient products into the markets should definitely shift to custom sheet metal to meet all their production goals and increase their profit.

Simple & Easy Guide to Plastic Extrusion

Extrusion is one of the earliest and most cost-efficient manufacturing techniques. Advanced modern manufacturing techniques and materials have led to increased interest in plastic extrusion manufacturing. Thermoplastics, the primary choice in plastic extrusion, are lightweight, versatile, and inexpensive.

But the materials choices and variations in the extrusion process can be very complex and confusing.

So, here is your basic guide to help you better understand the Plastic Extrusion Process.

Plastic Extrusion

What is Plastic Extrusion?

Extrusion is the process of material forming where the application of force pushes material through a small orifice or die. Plastic extrusion is a manufacturing process where melted plastic is pushed through a die to form a continuous profile shape.

Process of Plastic Extrusion

Here is a brief overview of the extrusion process for plastic materials.

Plastic Extrusion

Step 1

The raw plastic material is formed into small pellets called nurdles (also known as plastic beads or resin). These nurdles are approximately 5 mm in size and often contain color or UV protection additives.

Step 2

Once the raw plastic beads are pre-processed, they are steadily fed into the hopper. The hopper base is conical and connects to the barrel via the feed throat, a small opening on the barrel’s surface.

Step 3

Once inside the barrel, the plastic beads are gradually heated to their melting point. The heating is done through several heating elements placed across the length of the barrel. The gradual increase in temperature allows for controlled melting and avoids overheating.

Step 4

A large rotating crews cover the inside of the barrel. As the screw rotates, it moves the plastic beads towards the front of the barrel.

Step 5

At the front end of the barrel lies a screen used for filtering any unwanted contaminants in the now molten plastic. A breaker plate reinforces the weaker screen and ensures it can withstand the high pressures.

Step 6

Once the molten plastic is filtered through the screen, it goes into the die shape, sometimes through a feed pipe. The die determines the final cross-section (profile) of the extrudate.

Step 7

With the plastic extruded, it is set to cool down to room temperature. Passive air cooling is adequate for thin profile parts, but thicker parts require water cooling.

The extrusion process is versatile and can be modified to suit specific applications. By simplifying changing out the die, you can extrude an entirely different part using the same machine.

Types of Plastic Extrusion

Following are some basic types of the plastic extrusion process.

Tubing Extrusion

This type of plastic extrusion is used for making tubes, pipes, and other cylindrical shapes. Here a positive pressure is applied to the center of the die and negative pressure to the outer diameter of the die, resulting in the formation of a pipe shape.

Sheet or Film Extrusion

Sheet extrusion uses a T-shaped or coat hanger-shaped die to extrude a thin and flat plastic sheet. Sheet plastics are used in various industries, the most common one being thermoforming or vacuum forming.

Blown Film Extrusion

Blown film extrusion is used to manufacture even thinner films of plastic. Here a pneumatic system is attached to the end of the die that uses airflow to manufacture a thin and consistent plastic film.

This method can use three types of dies for extrusion.

1.Spider 

2.Annular (Crosshead)

3.Spiral

Over Jacketing Extrusion

Over jacketing involves coating a long wire or cable of material with plastic. Here a wire is fed through the die, and the die pushes the molten plastic around the wire.

Extrusion Coating

Extrusion coating is the same process as over jacketing, but for flat pieces of material. The most common example of this manufacturing process is Tetra Pak packaging, where paper is coated with a thin plastic film.

Co-Extrusion

Co-extrusion involves two or more plastic materials being melted and extruded through the same die. This extrusion method is a more advanced form of other plastic extrusion processes. 

(over-jacketing, tubing, sheet, and blown film)

Extrusion Plastics

The extrusion process is compatible with many thermoplastic bases. As long as the plastic material can be reliably melted without reaching the thermal decomposition point, it can be used in plastic extrusion machines.

Here is a list of commonly used extrusion plastics.

Plastic Extrusion

In some rare applications, an elastomer or thermoset plastic is more beneficial instead of using thermoplastics.

Applications for Extruded Plastic

Extruded plastic is used in several industries and our daily lives. Here are a few examples of extruded plastic parts.

Plastic Extrusion

Benefits of Extruded Plastics

  • Plastic extrusion can be used to manufacture large lengths of tubing and piping. 
  • Extrusion is particularly suited to high-volume manufacturing.
  • Extrusion is a very cost-efficient process
  • Relatively quick turnaround time.

Aluminum Extrusion

Aluminum extrusion uses the same basic operating procedure as plastic extrusion but with a few small changes.

1.The base aluminum is in the form of a large Billet instead of small Pellets.

2. Aluminum is heated to a high temperature but not melted.

3. Extrusion requires several tons of force, applied through a hydraulic mechanism.

Conclusion

Plastic extrusion is a quick and reliable mass manufacturing process suited to various applications. A few variations in the extrusion process result in different end products, but the base procedure remains the same. When selecting the desired plastic material, you must ensure that said material is compatible with your chosen extrusion process.

How does CNC Machining Ensure Precision in Making Complex Parts?

CNC machining is a cornerstone of modern manufacturing services. Along with quick turnaround times and versatility, CNC machining is also known for its excellent precision. Of course, precision becomes more important when matching a complex part. However, an increase in part complexity will increase the failure chance during machining.

Thus we present to you the benefits of CNC machining in complex parts.

What is CNC Machining?

CNC machining stands for Computer Numerical Controlled machining. Here a computer (microprocessor) is responsible for the accurate and precise motion of the cutting tool. The tool subtracts material from a solid blank (called a workpiece) until the desired geometry is achieved. CNC machining is an incredibly precise and time-efficient manufacturing method.

Complexity in CNC Machined Parts

Here are the critical elements of CNC machining that contribute to part complexity.

CNC Machining

a.Geometry

Geometry complexity refers to the number of design elements present in a single part. These design elements consist of holes, cuts, pretensions, undercuts, etc.

b.Size

The part size itself is not responsible for part complexity but is still a significant contributor. Machining a larger-sized part is considerably easier than machining the same design but at a smaller size. Additionally, large parts can be machines at a higher speed than smaller parts.

c.Machining

Machining is a design-dependent property of CNC. Complex geometric designs require machining using multiple cutting tools and changing workpiece orientation. Some designs cannot be machined using standard 3-axis CNC machines.

d.Tolerances

Tighter tolerances for any design will slow down the manufacturing process. As tolerances shrink, the amount of machining precision requires increases exponentially. Additionally, the same tolerance for a smaller part will result in added complexity than it would for a large part.

Precision in CNC Machining

Precision is the quality of a device that is responsible for consistent results upon repetition. In short, CNC precision ensures that every machined part has similarly accurate dimensions.

CNC machining precision is the result of several design choices. 

The following are critical elements of a CNC machine that increase the overall machining precision.

CNC Machining

1.Microprocessors

The compute element of a CNC machine is controlled by a microprocessor (computer). This little chip can make thousands of calculations per second, resulting in precise and accurate instructions to the motors.

Microprocessor technology has increased by 100 times in just the past two decades. With faster processing, CNC machines can cut material with even greater precision and less time.

2.Servo Motors

Motors are responsible for carrying out cutting instructions provided by the computer (microprocessor). However, motors are inherently inaccurate as their momentum keeps them from stopping at precise locations.

A servo motor uses specific electric currents to start and stop. This fine-tuned control system allows servos to carry out movement instructions provided by the computer accurately.

3.Multi-axis CNC Machines

Finally, the most significant contributor to modern CNC precision is multi-axis machines. A typical CNC machine only moves in three axes (directions), Up-Down, Left-Right, and Front-Back. This means operators will have to adjust the workpiece and change its sides for complex designs, which brings unnecessary variables and impacts the overall precision of the machine.

6-axis machines can move in the three directions but also rotate in the three directions, resulting in total coverage of the workpiece. You can cut complex designs into the workpiece with the click of a single button, with no need for operator guidance.

CNC Prototyping Machining Service

Prototyping is a necessary step in product development but a time-consuming and costly practice. Prototypes often need very precise tolerances so the design can be as close to the final product as possible.

CNC machining solves most drawbacks associated with prototyping. The precision of CNC allows for rapid turnaround times, meaning you can decrease the lead time between the design phase and the production phase.

Precision CNC Milling

Milling is generally restricted to simpler tasks, like surface milling or drilling. But newer multi-axis CNC machines are incredibly versatile and can create complex designs with unparalleled precision.

For example, monolith aluminum blocks are used to manufacture high-performance turbine blades. These turbine blades require utmost precision and accuracy. Each blade must be the same as the others.

Precision CNC Turning

Turning is performed on a horizontal machine called a Lathe. It is commonly used for objects with significant length-to-height ratios. CNC turning is an excellent option for machining threads, pipes, deep cavities, etc.

Since turning is performed on large objects, poor precision can have a snowball effect and result in large variations between parts. CNC turning ensures consistent and accurate machining operations.

The most significant benefit of precision turning can be seen in machined threads. Threads have standard sizes, and your parts must adhere to these strict standards. Luckily precision turning on CNC machines leaves no room for errors.

Surface Finishing

Machined parts often undergo secondary processing called finishing. Finishes like powder coating and painting can add 0.05 to 0.1 mm to the final thickness. While polishing can reduce the thickness by the same amount. These finishes have a tendency to exaggerate surface imperfections.

Your parts need to be machined as precisely as possible using a CNC machine for even and consistent finishing.

High Volume Production

CNC precision also proves extremely useful for large-scale productions of complex parts. CNC machines ensure each part closely matches the other, with as little variation as possible. This precision also results in quicker turnaround times and shorter lead times.

CNC Machining

Conclusion

Precision is an often overlooked benefit of CNC machining. However, after reading this article, we hope you better appreciate CNC’s precision. CNC machines will maintain their precision irrespective of your cutting tools, design geometry, and tolerances. You will need to rely on more advanced CNC machines, like a six-axis CNC, for even better precision.
