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...

(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...

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...

How to increase the gloss of ABS injection-molded products?
2024-11-11
Injection Mold 1. If the mold cavity is poorly machined, with defects such as scratches, micro-pores, wear, or rough surfaces, it will affect the gloss of the plastic part. To address this, ensure precise machining of the mold to achieve a lower surface roughness for the cavity; if necessary, polish and chrome-plate the cavity. 2. If the cavity surface has oil stains, watermarks, or excessive mold...

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...
