What are the influential factors of glass fiber reinforced nylon material?
2024-06-24
Polyamide is commonly known as nylon (PA), its main feature is that the polymer main chain contains a large number of amide groups, these amide groups are easy to form hydrogen bonds with each other, and the force between PA molecular chains is strong. Therefore, PA has the characteristics of high crystallinity, high surface hardness, good chemical stability, high tensile and bending strength, wea...

Modulus and tensile strength of reinforced fibers for composite materials
2024-07-16
At present, as a common reinforcement fiber for composite materials, there are usually three types: carbon fiber, glass fiber and Kevlar (aramid) fiber. When used for composite reinforcement, the fibers can define the performance standards of the material and are responsible for playing a load-bearing role in the design structure, while the resin matrix is primarily responsible for transferring th...

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...
