Our outstanding peek manufacturing capability to delight your customers

RapidDone knows well for PEEK material, we are able to deal with different peek projects, and offers the most proper solutions. As an experienced PEEK plastic machining manufacturer, we are glad to manufacture quality and precision peek parts to delight your customers.

PEEK CNC milling services
PEEK CNC turning services
PEEK rapid prototyping services

CNC turning method is the key machining method for our PEEK fabrication services. We are able to create precision parts with different sizes from rod material and rube material at a quick turn-around.

RapidDone holds one 5-axis CNC machines, this makes us be able to build complex PEEK components directly from customer-supplied CAD models in a single operation.

As a professional rapid prototyping manufacturer, we know well for all common engineering materials. We have rich experience to run the PEEK projects by exceeding customer’s expectations.

The Basics of PEEK Plastics

PEEK is also known as Polyetheretherketone. It is a high-performance engineering plastic material with excellent wear resistance, chemical resistance, biocompatibility, high stiffness, and high strength. Another benefit is the high temperature withstanding ability that performs well at a temperature of 480°F.

Manufacturing Processes For PEEK Parts

Usually, PEEK materials are available in sheet, rod, tube, film, and plastic granule format.

When creating PEEK parts, there are two main manufacturing processes for them.

The first way is CNC machining and fabrication, the raw material is PEEK sheet, rod, tube, film. It is ideal when you are in need of small quantities for rapid prototyping build or low-volume manufacturing build. At RapidDone, we have an experienced team and be able to finish prototypes orders in several days.

The second way is plastic injection production, the raw material is PEEK plastic granule. It is suggested to use this for the high-volume order. At RapidDone, we can use rapid injection molding services to have parts done in two weeks.

The third method is 3d-printing, this is a low-cost way to make PEEK prototype parts in the fastest way.

Manufacturing Processes

The Applications

There are two types of PEEK material: industrial-grade PEEK or medical-grade PEEK, each is used into different applications.

Industrial-grade PEEK is most commonly used in common manufacturing industries, including automotive, aerospace, chemical, semiconductors and electronics, oil and gas, as well as food industries.

Medical-grade PEEK, on the other hand, is wildly used for custom medical components applications, such as spinal devices, articulating joints, and other medical equipment applications.

Six reasons where distortion may happen for PEEK machining

• It does not apply an annealing step to remove internal stress or internal stress is not removed completely.
• The cutting depth is too much.
• There is no coolant progress.
• The cutting is not a balanced cutting, one side cutting volume is bigger than the other side.
• The PEEK workpiece clamp is not firmed enough which causes vibration during machining.
• The clamping force is too big that distort the workpiece.

Does PEEK part easily get Burr during machining?

Yes, it easily creates burr because PEEK material has high tenacity.

There are four ways to get less rid of the burr.

• Try to use the diamond tool and keep the tool to be as sharp as possible during machining.
• Add chamfer feature to get rid of the burr from edges.
• Use second operation progress to remove the burr.
• Try to use glass filled or carbon filled PEEK material instead of normal types of PEEK material.

The Recommended tips for machining Peek parts

Take Annealing process

Peek sheet or rob is a special material, it easily creates high internal stresses during the machining process. This internal stress leads to possibilities of surface cracks formation. It also reduces to part to get tight tolerance and flatness.

To fix this issue, the solution is to take the annealing step to relieve the stress before you start the machining work. Besides, some PEEK parts may take additional intermediate annealing processes if the machining time is too long.

Make a correct tool selection

That depends on the material types you are going to the machine.

When cutting natural PEEK material, it is suggested to use sharp silicon carbide tools.

When cutting carbon-fiber-reinforced PEEK material or bearing Grade PEEK material, it is ideal to use a higher hardness tool such as a sharp diamond tool.

Handle well for the chips

PEEK has high tenacity, the chip is not easily cut into pieces. Thus, it may be easier to get around your tool and melt on the tool surface.

To avoid this, you need to use the right tool to ensure the chips fly. At the same time, monitor the machining closely, use the vacuum to clear chips on time before it turns into a big problem.

Preventing Contamination of PEEK medical-grade workpieces

It is important to dissipate the heat during the PEEK part machining by using a coolant, the best way is to machines dry. In that case, the air is used as the coolant, this can avoid jeopardizing the biocompatibility for medical-grade PEEK material components.
