10. Can You Make Heat Resistant Parts with CNC Delrin?

Materials are usually divided into two categories based upon their properties and reactions to high temperatures. One class is named ‘Thermosets’ while the other is called ‘Thermoplastics.’ Now, Delrin is categorized as the second category, thermoplastics.

Figure 10 – CNC Delrin Parts

The materials belonging to this class are sensitive to heat. This means they cannot withstand high temperatures and pressure. The same is the case with Delrin too. Once the temperature rises from a bearable amount, this material starts melting. The max temperature at which you can machine Delrin is around 121 degrees. However, it is better to keep the temperature as low as possible.

Now, as Delrin is a thermoplastic, you cannot use it to make temperature-resistant parts too. Delrin is not an ideal choice in case you need a part that must be able to bear extreme temperatures.

Not only Delrin but usually all the plastic materials are known to melt at high temperatures. Their melting points are low. Thus, you shouldn’t be choosing them to make heat-resistant parts with CNC machining.

11. What Things Should You Keep in Mind While Carrying Out the CNC Delrin Process?

Delrin is not a material similar to metals or steel. It has a nature of its own and thus, needs specific care while working on it. It’s not much, but there are some things that you need to consider while you are manufacturing parts with CNC Delrin.

· Maintain Consistency in Design

Delrin is not as strong as aluminum and other similar metals. Therefore, you need to be vigilant while designing your parts in this method. Maintaining consistency is a significant aspect to keep in mind while working on parts using the CNC Delrin method.

For example, keep the thickness of outer walls similar so that the part comes out to be stable and functional. You can also add handy objects such as rubs and fillets in the design for better results.

Figure 11 – Machining Plastic

· Keep Temperature Low While Machining

As described earlier, Delrin is a thermoplastic, meaning it is not good with heat. Therefore, it is crucial to maintain a low temperature while machining this material. You can use coolants where the machining process is taking place to keep the temperature lower than 120 degrees.

If you forget to do this, the material might start melting during machining, ruining the entire process. If you are unsure of being able to maintain temperature and machine Delrin simultaneously, you can hire manufacturers from China to help you do it.

· Delrin is Not a Metal

Usually, people work with metals in CNC machining and forget that Delrin is nothing similar to that while machining it. You need to make preparations, carry out the machining and finishing process differently for CNC Delrin than you used to do for metals.

First of all, you must use clean cutting tools and machinery for the process. Otherwise, the previous metal or its traces may mix up with your Delrin material and contaminate the result. To get outstanding results, it is essential to use perfect tools too.

· Sharp Cutting Tools Will Work Wonders

Delrin is near to plastic, which means it is not a super-hard material. However, that doesn’t mean using any kind of cutting tools for CNC Delrin. If you need the best results with sharp edges and excellent designs, you must use excellent tools too.

Figure 12 – CNC Machines for Delrin Fabrication

So, it is better if you opt for sharp cutting tools with lubricants for the fabrication of Delrin. It will give you perfect clearance angles. Plus, you will also be able to make the shapes that you desire. Otherwise, low-quality cutting tools will do nothing but give you roughly cut parts and poor-quality products.

· Be Gentle with the Process

Delrin isn’t a delicate material, but it is also not super strong and solid. If you apply strong forces during the manufacturing process, you might end up with the wrong design or a broken part.

When performing the CNC Delrin process, you must always keep in mind to handle the parts and process with gentleness. Of course, being gentle doesn’t mean handling this material as it is a super delicate thing. But it does mean to apply lesser forces on this material as compared to the ones you apply on metal and steel.

CNC Delrin is a method that requires delicacy and strength at the same time. Once you know perfectly how to balance these two, you’ll be able to manufacture great products with this method. However, hiring professional manufacturers and ordering them to make these parts for you can save you tons of time and money. Plus, they can produce the parts for you that you require in lesser time durations.

12. What Should be the Surface Speed of the Cutter During CNC Delrin?

The ideal machining Delrin feeds and speeds would be 375 ft./min. Maintaining the perfect speed and rotations is essential during the machining process. If you don’t take care of them, you might end up with roughly cut and unwanted parts.

Figure 13 – CNC Machining Processes

The speeds of machine cutters vary from part to part, material to material, and process to process. However, you can discuss your requirements with proficient suppliers and let them help you decide on a perfect speed value for your CNC Delrin manufacturing.

13. Why Controlling Frictional Heat is Easy During CNC Delrin?

The answer to this question is also hidden in the fact that Delrin is a plastic that belongs to the thermoplastics category. These materials are less hard and have a modulus lesser than metals. Lower modulus means more flexibility characteristic in the material.

Now, as Delrin also has a lower modulus, it shows less friction too. Thus, it doesn’t produce much frictional heat during the process and makes it easier to keep the overall temperature maintainable.

Figure 14 – Delrin Parts

The low friction thing also makes the material useful in many cases. For instance, you can the parts made from CNC Delrin for a long time. You can make wires and long chains for different purposes using it. Apart from that, CNC Delrin can also help you create parts for the processes that require lubrication-free work.

14. Which Material is Stronger, Delrin or Nylon?

Delrin is comparably stronger to nylon. Both materials are good for manufacturing plenty of products. However, when it comes to strength and sturdiness, Delrin is better. Nylon is also a kind of plastic that has strength and durability of its own. But it is lesser than that of Delrin plastic.

So, if you’re going to choose between both these plastic materials, you should choose to depend upon your requirements. Delrin will make a better and more appreciable choice if you are looking for a stronger part. However, some expert manufacturers can share more details about both these materials and help you choose between them.

15. How Laser Cutting is Effective During CNC Delrin?

Delrin is an easy-to-machine material. That means you don’t require a lot of effort and strength to cut Delrin. That is why a laser can cut it with great proficiency. You will get a highly functional and well-designed part if you cut Delrin with a laser.

Figure 15 – CNC Laser Cutter

Laser cutting is an efficient cutting process that ensures perfect edges and engravings on the product. And as Delrin can easily be cut through laser, it is highly preferred to use this method for CNC Delrin.

16. Should You Opt for CNC Delrin If You Have a Tight Budget?

Yes, of course, you should. In fact, it’s a great choice to make, especially when you’re tight on a budget. Delrin is a cheap material. All plastics are relatively cheaper as compared to metals and heavy materials. Delrin requires lesser investment too.

So, you don’t need to worry if you don’t have a huge budget. It is because many manufacturers in China can help you with the CNC Delrin process at lesser rates. Some plastics are expensive too. However, Delrin isn’t. It costs less than many other plastic materials, including PTFE, PA66, etc.

Figure 16 – CNC Delrin Parts

Another thing that makes you spend lesser on Delrin is its dimensional stability. The parts don’t need to go through multiple test sessions or trials. This saves a lot of your money. The processes in which the CNC parts require testing costs more too. In a nutshell, CNC Delrin doesn’t cost you a lot and can be helpful for you if you don’t have a lot to spend on the process.

17. How CNC Delrin Process Reacts with Chemicals?

Delrin is a material with intense bonding and rigid molecules. It does not react with chemicals present around it. That is why you can use it for various machining processes without worrying about chemicals reacting to it.

Its chemical resistive nature also limits the use of Delrin at different places. Adhesives that are commonly used during CNC processes are also chemical. And as Delrin doesn’t react to them, adhesives don’t work on the material either. Thus, it becomes hard to machine the parts and join them together.

Figure 17 – Acetal and Delrin Parts

That is also why you cannot use this material for the making of large structures and parts as they can fall apart quickly. But at the same time, you can easily use it in different manufacturing processes with lubricants and coolants.

18. How Can Manufacturers Help You in CNC Delrin?

POM CNC is a good process, but you do need professional help to carry it out with perfection. POM is divided into plenty of materials, including acetal, Delrin, etc. If you want to make parts using this process, you need to choose a suitable CNC method and material.

CNC Delrin is a helpful process when it comes to manufacturing parts for various uses. It is also cost-effective and doesn’t require a lot of effort.
