Common Manufacturing Methods for PPSU Rods and Boards

Views: 562 Author: Site Editor Publish Time: Origin: Site

Polyphenylsulfone (PPSU) is a high-performance engineering thermoplastic that offers exceptional thermal stability and resistance to chemicals. It is commonly used in various industries, including aerospace, automotive, and medical, due to its excellent mechanical properties. PPSU is available in different forms, such as rods, sheets, and tubes. In this article, we will discuss the common manufacturing methods for PPSU rods and boards.


Extrusion is one of the most common manufacturing methods for PPSU rods and boards. The process involves melting the PPSU resin and forcing it through a die to create a continuous profile. The extruded PPSU profiles can be cut into desired lengths to produce rods and boards of different sizes. Extrusion allows for tight tolerances and consistent quality control, making it an ideal manufacturing method for high-volume production.

Compression Molding

Compression molding is another popular manufacturing method for PPSU rods and boards. The process involves placing PPSU resin in a mold cavity and compressing it under high pressure and temperature. This results in a solid and dense product with excellent mechanical properties. Compression molded PPSU rods and boards are often used in applications where dimensional stability and strength are critical.

Injection Molding

Injection molding is a versatile manufacturing method that can produce complex shapes and sizes of PPSU rods and boards. The process involves melting the PPSU resin and injecting it into a mold cavity under high pressure. Once the material cools and solidifies, the mold can be opened, and the finished product can be removed. Injection molding is ideal for producing small to medium-sized PPSU rods and boards with high precision and consistency.


Machining is a subtractive manufacturing method that involves cutting, drilling, and shaping PPSU rods and boards using CNC machines. Machining allows for flexibility in terms of size, shape, and tolerances of the final product. This method is particularly useful for producing custom-designed PPSU parts that cannot be manufactured using other methods.
