Peek Injection and Its Advantages and Disadvantages

 

Peek injection is a type of plastic injection molding that uses a proprietary blend of polyether ether ketone to create high-quality, strong parts. It offers superior mechanical, wear and heat resistance, as well as chemical strength, and can be used in harsh environments. Peek is also highly recyclable and has excellent electrical insulation properties. It is ideal for aerospace and automotive applications, as well as medical devices and other mechanical components.

The peek injection process involves bringing the polymer to a melting point, so it can be injected into a mold under high pressure. Then, the mold is cooled, and the completed plastic part can be removed. The process can produce a wide variety of shapes and sizes, as well as complex features that require precise engineering. It can also reduce costs, as the need for machining is reduced and assembly time is eliminated. In addition, the injection molding process is environmentally friendly, since it does not involve the use of solvents or toxins.

One of the key challenges of peek injection is maintaining the proper processing temperatures during the injection molding process. If these are not met, the resulting molded plastic can suffer from fatigue and stress cracking. Additionally, if the temperature is too low, the plastic can become soft and brittle.

To avoid these problems, it is important to choose an experienced injection molding company with the right equipment. Injection molding companies must have the ability to control the precise temperature required for each plastic. This ensures that the polymer will solidify properly in the mold, and that it will not be subjected to a large amount of stress as it cools.

It is also important to know that the injection molding process can cause shrinkage in the finished product. This is due to the fact that the material must cool at a different rate than the mold. To avoid this issue, it is a good idea to use fillers such as glass fiber, carbon fiber or graphite. These additives can also improve the surface hardness and abrasion resistance of the plastic.

Injection molding Ohio companies that use PEEK often add these fillers to improve the mechanical properties of the resulting plastic part. In addition, they may also use them to increase the dimensional stability of the finished product. Adding fillers can help reduce the risk of sink marks and other defects that are common in injection molded plastics.

Injection molding of PEEK requires specialized equipment and knowledge to achieve the best results. In addition, PEEK is a specialty plastic that is expensive compared to other injection materials. Therefore, it is a good idea to contact an expert injection molding company for more information about the procedure and the benefits of using this material.
