How Can You Cut A Polycarbonate Sheet With Circular Saw In Polycarbonate Fabrication?

You can cut the sheet with the circular saw with carbide teeth.

It is essential to run the circular saw with a speed range of 6000-8000 ft/min to get the best results and the blade of the saw must have 3-5 teeth per inch.

You need to make sure that you have smooth tabletops while cutting the polycarbonate sheet and the surface should be free from projections.

Otherwise, there would be scratches on the polycarbonate sheet.

There should be a minimal gap between the saw blade and table edge.

 Cutting with circular saw

How Can You Prevent Bubbles Or Blisters During The Process Of Polycarbonate Fabrication?

It is possible that during the processing of polycarbonate sheets, bubbles, or blisters are formed due to moisture in the sheet which can damage the process of fabrication.

It is vital to clean the fabrication sheet or pellets and make sure it has no moisture in it.

Can You Bend Polycarbonate during Fabrication?

 Bending Polycarbonate Sheet

Generally, there are two types of processes involved in the bending of polycarbonate during the process of fabrication.

The following methods of bending polycarbonate are used.

· Brake Bending

In this method, polycarbonate sheets are break bent up to 90 angles in gauges.

However, the bending of heavier gauges can crack or break the polycarbonate sheet due to high pressure or stress applied to the bending area.

For angles in higher gauges, strip heat bending is recommended.

· Cold Bending

This method is used for the polycarbonate sheets with a minimum radius depending upon the sheet thickness.

The material of the polycarbonate sheet can have a radius up to 100 times the thickness.

Does Polycarbonate Absorb Water During Fabrication?

During the process of polycarbonate fabrication, polycarbonate absorbs water at two different stages.

In the first stage, the water is absorbed due to elevated temperature during the process when cooled to room temperature.

In the second stage, the additional water is absorbed by the polymer in a separate liquid phase known as clustered water.

Do You Need to Clean Polycarbonate Sheets Before Fabrication?

It is advised that you clean the polycarbonate sheet before fabrication with lukewarm water.

If required, you can use some soap or detergent to clean the sheet so that you can get rid of dust particles and dirt.

The cleaning of polycarbonate sheets before fabrication helps to remove any impurities before you transform the polycarbonate sheets and fabricate them into different shapes.

Are Polycarbonate Products Toxic?

Most of the products made of the polycarbonate sheets can be considered as dangerous when they come in contact with food-related items due to the potential release of Bisphenol A (widely known as BPA).

The material may degrade when it comes into contact with hot water.

Most of the products made from polycarbonate use the combination of phosgene and BPA.

Is Polycarbonate Bad For The Environment?

It is a fact that polycarbonate material contains bisphenol A which is dangerous for human consumption.

Hence, its use is just limited to industrial purposes and manufacturers are not using this for food-related packaging or consumption.

It poses a great threat to the environment as the chemicals leach into the environment and results in the formation of gases and hazardous liquids.

Traditional polycarbonate made with bisphenol A is not biodegradable and causes damage to the environment.

Is Polycarbonate Biodegradable?

There are certain types of polycarbonate that have been manufactured from aliphatic hydrocarbons which are biodegradable.

These polycarbonates will biodegrade with the help of enzymes or bacterial cells.

Traditional polycarbonate made with bisphenol A, however, are generally not biodegradable and still remains widely used for industrial purposes.

You can verify with your manufacturer on the type of polycarbonate sheets you are intending to order to find out if they are biodegradable.

 Biodegradable Polycarbonate

Can Polycarbonate Sheets Resist Heat If They Can Be Thermoformed?

While polycarbonate sheets can be thermoformed, this is done at extremely high temperatures.

Polycarbonate sheets are very useful in shelters and greenhouses as these panels provide good resistance against heat, water, moisture, ultraviolet rays, and snow.

It is formed of thick material which can withstand temperatures in extreme weather and large amounts of force or pressure, and provide enough resistance against any shock or hit.

Thus, it makes a good choice for sunlight protection as the polycarbonate can naturally resist heat and protect you from ultraviolet rays.

Polycarbonate block heat

How Can You Thermoform Polycarbonate Through Heating Into Different Shapes?

If you want to thermoform polycarbonate sheets into different shapes then it must pass through heat penetration at 350 degrees F to 360 degrees F.

You need to pre-dry the polycarbonate sheet to ensure all moisture is removed otherwise bubbles may form in your sheet.

It even takes a higher amount of heat to fabricate the polycarbonate sheet into more complex shapes.

You need to have even heating over the entire sheet with an air circulating oven. You can use vertical hanging or infra-red heaters for this.

When you are ready to shape the polycarbonate sheet, remove the heaters and pre-blow the sheet.

Vacuum forming is usually used here to form the sheet over the mold and get the right shape.

A good amount of temperature control at each stage is needed for optimal results.

Once you have gotten the desired shape, you can wait for the polycarbonate sheet to cool down before lifting it up from the mold.

How Can You Find A Manufacturer To Do Polycarbonate Fabrication?

If you want to get a custom shape, size, and design of a polycarbonate sheet without doing any fabrication yourself, then you can search for any plastic manufacturer that can do the fabrication of polycarbonate sheets.

These companies can help to get you custom design, shape, and cut to size panels for your use.

These companies have a large fabrication facility with design and development teams that can fulfill all the needs of their clients.

You can get assistance for custom design, development of concept work, and sketching of any product of your choice.

Can You Cut Polycarbonate Sheets For Fabrication?

There are different methods used for cutting of polycarbonate sheets during the fabrication.

For the small jobs, hand cutter and box knives can be used.

For the large sheets that you need to cut, you can use wooden saws, circular saws with the fine sharp blades for cutting the polycarbonate sheets.

When the polycarbonate sheets are cut to size, it gets small particles through the flute channels and it would require compressed air to clear the flutes.

You can watch this video to find out how to cut your polycarbonate sheet.

Can You Drill Holes In Polycarbonate Fabrication?

You can easily drill polycarbonate sheets using the conventional drilling machines used for woodworking.

However, you need to make sure that you don’t crack the entire panel while drilling and use all the safety precautions while drilling the sheet.

It is advised to avoid using a center punch on a polycarbonate panel in any case because it will damage the sheet.

Drilling holes in polycarbonate

How Do You Join Polycarbonate Sheets?

The polycarbonate sheets can be joined with the help of bolts and nuts.

The sheet needs to be drilled with the help of a conventional woodworking drill and then fixed at any angle with the help of nuts and bolts.

It takes aluminum rivets and machine screws for proper attachment of the sheets together.

You can also use cyanoacrylate glue to join the polycarbonate sheets but you have to make sure you clean the polycarbonate sheets before gluing.

This will ensure that there will be no contaminants that mix with the glue and interfere with its effectiveness.

You can also use polycarbonate profiles to join your polycarbonate sheets with additional support.

Put the polycarbonate sheets in place and slide your polycarbonate profiles between them to join them.

What Is Vacuum Forming In Polycarbonate Fabrication?

When the polycarbonate is heated at forming temperature and stretched into the single surface mold using the vacuum, this process is called vacuum forming.

The process of vacuum forming is used to create permanent plastic objects such as covers,  signboards, and packaging material.

Can You Walk On A Polycarbonate Sheet?

You can only walk on a polycarbonate sheet if it has enough thickness backed with good support.

You have to spread out the weight.

Test it first to be sure it can support your weight without difficult and stay on all fours, so your weight is calmly distributed.

What Is The Difference Between Machining Polycarbonate Vs Acrylic?

Polycarbonate is a flexible plastic and comparatively easier to machine with the help of milling and sawing than acrylic.

The reason is that polycarbonate doesn’t break easily even in the process of machining so it is more durable than acrylic.

It is also less likely to warp under a large amount of pressure compared to acrylic.

When it comes to machining both of them, the major disadvantages come for acrylic because it is easy to crack the acrylic sheet during the machining process and its wastage level is much higher than that of polycarbonate.

Acrylic is also more likely to chip and has lower heat resistance so they are more likely to melt or warp when it is exposed to high heat.

Polycarbonate is easier to thread and fasten with the help of nuts and bolts without putting too much stress on the sheet.

However, polycarbonate is more likely to get scratches or dent during fabrication and machining.

It is possible to get polycarbonate with an abrasion-resistant coating, however, it is usually costlier than pure polycarbonate.

Polycarbonate is also generally a more expensive material compared to acrylic.

Can You Router Cut Polycarbonate?

Yes, you can router cut polycarbonate.

Make sure your feed rate is high enough to minimize melted polycarbonate chips.

Use an O flute which will give you the right cutting geometry and clearance angle

You can use a scraping motion to smooth a finished cut.

For a clear finished edge, you can consider using an industrial machine that traps the sheet and drags it along a diamond blade or fixed carbide.

Does Polycarbonate Scratch Easily?

Although polycarbonate is known for its high impact resistance, it can scratch easily.

For this reason, clear surfaces such as a polycarbonate lens will typically be coated with a scratch-resistant layer for protection.

Does Polycarbonate Crack When Drilled In Fabrication?

Polycarbonate sheets are easy to crack during the process of fabrication while drilling if the proper mechanism is not followed for drilling.

If you are using the wrong kind of tool and not using a stable surface when you are drilling, then it can result in chipping of the edge and can make cracks in the sheets.

When pressure is applied to plastic, it travels alongside the polymer chains inflicting molecules to strain to remain in contact.

The polymer chains finally creep in the direction of the pull and deform.
