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...

(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...

The application of high-performance long glass fiber (LFT) materials in explosion-proof cameras
2024-10-28
As we all know, explosion-proof products have extremely specific requirements—explosion-proof ratings, material standards, sealing performance, functionality, certification requirements, and more. Among these, material requirements are particularly stringent. Taking explosion-proof cameras as an example, most currently use stainless steel or cast aluminum alloy for the casing, which can withstand ...

The application of advanced composite materials in drone structural components.
2024-10-28
Unmanned Aerial Vehicle (UAV), commonly referred to as "drone," is an aircraft that is operated without a human pilot on board, using radio remote control and onboard programmed control systems, or fully or intermittently autonomous operation via onboard computers. As a new type of aircraft, drones differ from manned aircraft in terms of operational requirements and mission objectives. Drones typi...

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...

Long Carbon Fiber vs. Short Carbon Fiber in 3D Printing
2024-11-11
In 3D printing, both long carbon fiber and short carbon fiber are used as reinforcement materials to enhance the strength and durability of printed parts. Here’s an overview of their differences: 1. Long Carbon Fiber Long carbon fibers are continuous strands that are incorporated into the printing material. This type of fiber provides superior strength, stiffness, and structural integrity to the p...
