How to Get the Most Out of Peek Molding

Peek molding is a form of injection mold manufacturing that allows the use of polyether ether ketone (PAEK) plastic. This polymer is a special engineering plastic with exceptional comprehensive performance and can replace metals in many applications. Its characteristics include high temperature resistance, self-lubrication, easy processing, and high mechanical strength. PEEK can also withstand harsh environments and resist chemicals, making it one of the most popular high-performance plastics used in manufacturing aerospace and automotive components, machinery parts, and medical equipment.

PEEK injection molding produces high-quality plastic products for a wide range of applications, including aerospace and automotive components. PEEK is a semi-crystalline polymer with a molecular structure that includes both ordered and unordered molecules. The aryl and ketone portions of its build-up give it rigidity, stiffness, and strength. It is a flame retardant and insoluble in most solvents except concentrated sulfuric acid, making it resistant to chemical exposure.

It is biocompatible and sterilizable, making it a good choice for medical tools and other healthcare applications. It also possesses superior wear resistance, which is aided by the addition of graphite and PTFE lubricants. It can withstand radiation, including gamma and UV, for sterilization purposes without losing its chemical or physical properties.

The best way to get the most out of PEEK injection molding is to understand its unique properties and limitations. It is essential to select a plastic injection company that specializes in this material, and can handle the challenges of molding PEEK. PEEK is not as flexible as other plastics, which can lead to problems with dimensional accuracy and surface finish. The right plastic injection company can help ensure a quality part by using the right tools and techniques.

To make sure the injection process yields a high-quality finished product, the injection molder must follow strict production protocols. It must dry the PEEK pellets well before starting the injection process, and ensure that the mold has big gates to minimize air pockets and surface defects. It must also be careful to keep the temperature constant during the injection process, and maintain the correct holding pressure after the injection process. It should also consider adding carbon fiber fillers to reduce the overall shrinkage of the molded part.

While PEEK is an excellent polymer for a variety of applications, it is not the easiest to work with. PEEK requires a special injection mold that must be designed and built specifically for this material. It is important to choose a supplier with extensive experience in molding this material, and will be able to provide a cost-effective solution for your specific needs. Peek molding is a complex process, but with the right partners, it can be accomplished quickly and easily.
