(Ⅱ) How to deal with floating fibers on injection-molded parts?
2024-09-27
Mold temperature too low Cause: If the mold temperature is too low, the melt cools too quickly during flow, causing the glass fibers to not be fully encapsulated by the base resin and float to the surface. Solution: Increase the mold temperature appropriately to ensure the melt has sufficient fluidity to uniformly coat the glass fibers. Regularly check the mold temperature control system to ensure...

(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...

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...

Carbon fiber composite ballast tank for deep sea
2024-08-01
The traditional deep-sea ballast tank is mainly made of wrought steel, aluminum, titanium and other metal materials, and the technology is relatively mature. The weight of the ballast tank made of lightweight composite materials such as carbon fiber and polymer resin is 40% to 60% less than that of the metal tank of the same specification, which means that more scientific instruments can be carrie...

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...
