HDC for HDPE CNC machining

High-Density Polyethylene which is commonly known as HDPE is an amazing plastic for machining applications. Some of the common parts made from HDPE CNC machining are electrical parts, automotive parts, construction parts, etc. HDPE is largely resistant to chemical and thermal changes and offers a very good strength-to-weight ratio. Here is why you should choose us for your HDPE machining needs.

Available materials

HDPE is available in two grades, namely, 300 and 500 grades. Main difference between the two grades is of density. Generally, HDPE has a density ranging from 0.955 g/cm3 to 0.961 g/cm3. The tensile strength at yield is 23 to 29.5 MPa. Due to the high chemical resistance, HDPE machining parts are used extensively in the medical and food packaging industry. It not only keeps the food items fresh, it also does not allow bacteria and other organisms to grow on the HDPE parts.  



Is HDPE a good option for CNC machining?

Yes. HDPE is ideal for machining parts as it offers low resistance to tools and is resistant to temperature over a long range. Furthermore, the material holds firmly during the machining process, therefore, the tolerances are developed very precisely as per the requirement of the clients.

What are main applications of CNC Machined HDPE parts?

HDPE machining of parts is a very common practice around the world. There are food type HDPE materials and non-food type. The food type material is majorly used in the food packaging industry like bowls, boxes, packing, etc. Whereas, the non-food type HDPE is majorly used in electrical connections, packaging, connectors, automotive parts, etc.

Is HDPE machining a price effective solution?

Yes. HDPE is one of the most economical materials to use for a large number of applications. Even in comparison to a lot of metal and its alloys, HDPE machining is a much more economical and cost-effective solution. Furthermore, the cost of reworking, due to damages to the material, is very minimal when machining HDPE so it is an ideal choice for machining.

CNC Custom Plastic Machined Parts FAQs

China has been a hub for a wide variety of CNC custom plastic machined parts. But in choosing a supplier you’ll be working with, what do you look for? What do you consider?

Here at HDC Manufacturing, we don’t lock up our clients in a contract, we offer freedom of choosing. Of course, though, we perform the necessary imparting of knowledge and information to them. So, in this FAQ guide, we will be giving you complete information about plastic machined parts before you purchase!

Can Plastic Be CNC Machined?

plastic machining partsNo, not all plastics can be CNC machined. However, one thing to note is that the more rigid a plastic is, then, the easier the better machinability it has. On the contrary, the softer and more flexible the plastic, the less suitable they are for machining.

This paves way for the question, what types of plastics can I CNC?

What Plastics Can I CNC?

cnc plastic machining

In the world of machining, there are about a few different types of plastics that respond well to machining. These plastics include, but are not limited to:

  • Polycarbonate or PC
  • Acrylonitrile Butadiene Styrene or ABS
  • Nylon 66
  • Polyetheretherketone or PEEK
  • Polytetrafluoroethylene or PTFE
  • Ultra-High Molecular Weight Polyethylene (UMHW)
  • And many others

These are the most common types of plastics and thermoplastics that are commonly machined and worked on.

What is the Best Machinable Plastic?

figure 3 what is the best machinable plastic

Currently, the types of plastic that hold the trophy for the best Machinable plastics are: ACETAL, PVC, and PEEK. Let us discuss the reasons why they’re considered the best when it comes to machining, and how they came to be.


ACETAL is one of the leaders when it comes to fabricating plastic because of the fact that it has high levels of strength with low friction. In addition, it also boasts of low moisture absorption and extreme levels of dimensional stability.

Polyvinyl Chloride or PVC

Polyvinyl Chloride or PVC, for short, is another plastic type that’s excellent when it comes to machining and fabrication. The reasons why would be because of its multiple beneficial properties, which include water, flame, and corrosion-resistance; not to mention that it also has high levels of toughness, strength, and impact resistance!

Polyetheretherketone or PEEK 

Last but most definitely not least is PEEK, now, compared to the first two, PEEK or polyetheretherketone is considered an excellent machinable plastic because of high repeatability, tight tolerance levels, high melting points, and high accuracy.

NOTE: Even if these are the best and most effective types of plastic for custom machining, that doesn’t mean that you’re restricted to these. There isn’t a written rule saying that you CAN’T use other types of plastic for producing or fabricating machine parts.

Pros of CNC Custom Plastic Machined Parts

cnc machining plastic partsIn CNC machining alone, you’ll be able to find multiple benefits and advantages – what more if we combine CNC machining and thermoplastics?

These are the pros and advantages of using plastic CNC machining for the production of the parts you need:

Fast Turnaround

Plastic CNC products are the best when it comes to prototyping because it wouldn’t take you big number of hours for the prototype to be made. All that’s needed is the plastic material, as well as the design of the product to be manufactured, and the prototype will be made.

Faster prototypes always equate to faster turnaround of the parts or components needed.

Tighter Tolerances

Another benefit of CNC plastic machined parts is the fact that it can easily accommodate tighter tolerance requirements. So, if you are in an industry that requires more accurate and precise jobs, you won’t have a problem, not to mention that these can be prototyped faster and easier!

Better Wear Resistance

Last and most definitely not least is the fact that these products have benefits and advantages over metal parts – simply because they are plastic. In comparison to metal, they can be strong, resilient, durable, and resistant, too!

Challenges of CNC Custom Plastic Machined Parts

And if you think CNC custom plastic machined parts always offered rainbows and butterflies, that’s not the case. In fact, there are a couple of considerations before you go with CNC custom plastic machined parts – and these include, but are not limited to:

Warping and Tooling

The most common challenge or drawback to it is that warping and tooling of the components made is especially common. This is more prevalent when the part or the component only requires a thin piece of plastic.

Relatively Expensive

Another drawback is the fact that CNC machining is quite more expensive and costlier than traditional production methods. The use of high-quality CNC machines, and of course, expensive types of resistant plastic is what makes it heftier.

Where Are CNC Custom Plastic Machine Parts Used?
