Injection Molding Defect: Fiber Floating – Root Causes and Fixes
2025-06-20
In the injection molding process of glass fiber-reinforced materials, fiber floating is one of the most common surface defects. It appears as an uneven surface caused by exposed glass fibers on the part. This issue not only affects the visual appearance of the product but can also negatively impact secondary processes such as painting, coating, or electroplating. Today, we will take a deep dive in...

Automotive Interior Odors: An Unavoidable Challenge for Material Engineers
2025-07-10
Odor is both a sensory experience and a perceived measure of quality. In the confined space of a car cabin, the "new car smell" from plastics is not a symbol of luxury—instead, it often becomes a major source of consumer complaints. This article, grounded in engineering practice, systematically explores the sources, mechanisms, analytical methods, and controllable strategies related to odor. It ai...

The Science and Strength of PPS: A Deep Dive into Polyphenylene Sulfide
2025-07-21
Introduction Polyphenylene Sulfide (PPS) is a semi-crystalline thermoplastic engineering polymer composed of alternating benzene rings and sulfur atoms in its molecular backbone, with the structural formula -[Ph-S]n- (Ph representing a phenyl ring). This unique combination of rigidity and stability has earned PPS the nickname “Plastic Gold.” PPS Long Glass Fiber Reinforced Four Core Properties of ...

How Much Glass Fiber is Needed to Make Polypropylene Truly Fire-Resistant?
2025-08-29
In modern industrial fields, glass fiber reinforced polypropylene (PP/GF), with its low density, excellent heat and creep resistance, and high cost-performance ratio, has become a “rising star” in industries such as electronics, aerospace, and automotive manufacturing. This material is often used to produce lightweight and thin-walled components as a substitute for steel and conventional engineeri...
