PEEK injection molding is a high-performance plastic processing technology widely used in aerospace, medical equipment, automotive and other industries. However, during the PEEK plastic injection molding process, cracking often occurs in the product, among which cracking is one of the most common defects. This article will explore the causes of cracking in the PEEK injection molding process and propose corresponding solutions.

PEEK injection molding is the manufacturing of components by injecting its molten form into a mold. The form of the mold is adopted by the finished product after cooling and hardening. PEEK plastic injection molding is employed for high volume part manufacturing, where product consistency is the major problem. Additionally, this manufacturing method works for both thermoplastic and thermosetting polymers. A PEEK plastic injection molding machine, a mold, and plastic materials make up the PEEK injection molding apparatus. To simplify, PEEK injection molding is done in phases. It mostly breaks down into melting phase, injection phase, cooling phase, ejection phase, post-processing.

PEEK injection molding is a common plastic injection molding process. In the field of high-end manufacturing, PEEK (polyetheretherketone) has become the preferred material for aerospace, medical equipment, automotive electronics and other industries due to its excellent high temperature resistance, chemical corrosion resistance and mechanical properties. However, the PEEK Plastic Injection Molding process has extremely high requirements for equipment, technology and process management, and the slightest carelessness may lead to product defects or substandard performance. In this article, KRMOLD will systematically analyze the core precautions of the PEEK injection molding process to help you avoid risks and achieve high-quality molding.
