Plastic bearings: its type and advantages over metal
2024-07-24
After all, they may be used in rugged products and subsystem components, such as bearings made of alloys such as steel and bronze. Or they simply don't think plastic can handle harsh applications or extreme environmental conditions. But the fact is that modern plastic bearings (especially plastic ball bearings) can withstand extreme temperatures, heavy loads and high speeds. However, it is importa...

From steel to composite materials: Research of multiple materials for battery casings
2024-08-07
Battery is one of the most important core components of electric vehicles, whether it is in the face of high temperature, wading and even impact, the safety of battery protection can not be ignored. To protect the safety of the battery, the battery shell is the most important thing. Since the battery is the core key component of electric vehicles, electric vehicle researchers have focused their at...

Why do injection molded parts develop sink marks and dimples?
2024-09-02
(1) Improper control of molding conditions If the injection pressure is too low, the injection and holding time is too short, the injection speed is too slow, the material temperature and mold temperature are too high, the cooling of the plastic part is insufficient, the temperature is too high during demolding, the temperature around the insert is too low, or there is insufficient material supply...

(Ⅰ) How to deal with flow marks on injection-molded parts?
2024-09-27
(1) P: Poor flow of the molten material leads to the formation of concentric flow marks resembling growth rings on the surface of injection-molded parts, centered around the gate. When low-temperature, high-viscosity molten material with poor flow performance is injected into the cavity in a semi-cured, fluctuating state through the injection port and runner, the material flows along the cavity su...

(Ⅲ) How to deal with flow marks on injection-molded parts?
2024-09-27
Mold temperature too low Cause: The low mold temperature causes the molten plastic to cool too quickly in the runner, preventing full fusion. Solution: Increase the mold temperature to ensure the molten plastic flows smoothly and fuses completely. Injection speed too slow Cause: Slow injection speed causes the plastic to flow slowly, extending cooling time and forming weld lines. Solution: Increas...

Overview of 8 Non-Destructive Testing (NDT) Methods for Composite Materials
2024-11-01
Composite materials are new materials created through advanced material preparation techniques that combine components with different properties in an optimized manner. In the 1940s, due to the needs of the aviation industry, fiberglass-reinforced plastics (commonly known as fiberglass) were developed, marking the beginning of the term "composite materials." After the 1950s, high-strength and high...

Do you know which nylon materials are used in new energy vehicles?
2024-11-15
In the new energy vehicle materials industry, polymers encompass plastics, rubber, silicone materials, and composite fiber materials such as carbon fiber. To avoid safety hazards associated with high-voltage systems, materials for new energy vehicles must not only be heat-resistant but also flame-retardant. Therefore, Xiamen LFT has introduced a flame-retardant polyamide solution targeting manufac...

The Growing Demand for Long Fiber Reinforced Thermoplastic Resin: Revolutionizing Industries with High-Strength, Lightweight Materials
2024-11-26
In recent years, the demand for high-performance composite materials has soared across various industries due to the increasing need for materials that combine high strength with low weight. Long fiber reinforced thermoplastic resins, particularly those incorporating long glass fiber (LGF) and long carbon fiber (LCF), have emerged as strong contenders in replacing traditional metals in application...
