Composite Industry: LFT-D long fiber reinforced thermoplastics process introduction
2022-11-24
1 Overview 1.1 Introduction LFT-D is short for Long Fiber Reinforce Thermoplastic In Direct Processing. 1.2 Process Characteristics Compared with GMT and LDT-G, which rely on semi-finished plates or granules, LDT-D technology directly uses polymer masterbatch and glass fiber for daily production, which eliminates the intermediate process of plate making or granuleting, reduces cost and makes the s...

Analysis of carbon fiber reinforced plastic composite CFRP
2023-02-08
Carbon fiber reinforced plastic composite (CFRP) is a lightweight, strong material that can be used to make a wide range of products used in everyday life. It is a term used to describe fiber reinforced composites with carbon fiber as the main structural component. Note that the "P" in CFRP can also stand for "plastic" rather than "polymer." Typically, CFRP composites use thermosetting resins such...

The related knowledge of nylon
2023-02-23
Invention of nylon Nylon (Nylon), named Polyamide in English, is a man-made polymer. Wallace Carothers of DuPont invented the plastic on February 28, 1935, in Wilmington, USA. Nylon was officially marketed in 1938. The first nylon products were nylon brushes for toothbrushes (sold on February 24, 1938) and nylon stockings for women (sold on May 15, 1940). The appearance of nylon makes the textile ...

The differences, advantages and disadvantages of PP copolymerization and homopolymerization
2023-02-24
Polypropylene (PP) is divided into homopolymer polypropylene (PP-H), block (impact resistance) copolymer polypropylene (PP-B) and random (random) copolymer polypropylene (PP-R), so what are the advantages and disadvantages of all kinds of PP? I'll share it with you here. 1. Homopolymer polypropylene (PP-H) It is made by polymerization of a single propylene monomer. The molecular chain does not con...

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...
