In-depth analysis: 3D printing material polyamide PA nylon
2023-03-03
Nylon is a high performance polymer material in traditional industry. Nylon has also become one of the most widely used materials in 3D printing. PA6, PA11, PA12, PA66 and so on often appear in the available materials for 3D printing. In form, it is divided into powder materials which can be used for powder bed 3D printing technology, such as selective laser sintering (SLS) and multi-jet fusion (M...

Polyamide 12 LFT: Benefits and applications
2024-01-16
What is PA12-LCF? PA12-LCF is a thermoplastic material, belonging to the nylon class. PA12-LCF is based on nylon 12, which has 12 carbon atoms in each polymer repeat unit. Nylon 12 is also known as polyamide 12 or PA12. It is a semi-crystalline material with a high melting point (180°C) and a low moisture absorption rate (0.5%). It is also resistant to chemicals, wear and impact. PA12-LCF is a mod...

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...
