Q how to injection mold bulk molding compounds
HumphreyJudd
LionelVan Release Time: August 6, 2024, 5:15 AM
Injection molding of Bulk Molding Compounds (BMC) involves pre-heating the compound before injecting it into a heated mold at high pressure. The high viscosity of BMC requires the use of specialized screw designs and high injection pressures to ensure proper flow and filling of the mold. The mold is then held under pressure during the curing phase, which is critical for achieving the desired material properties and part geometry. Cooling systems within the mold help manage the exothermic reaction of the curing process to prevent defects. Key factors in the process include the precise control of temperature, pressure, and cycle time, tailored to the specific properties of the BMC being used. Optimal conditions depend on the filler content, resin type, and desired final properties of the molded part. Proper venting in the mold is also crucial to allow gases to escape and prevent voids or surface imperfections in the final product.

Q why is nylon called a linear polymer
MirabelleAustin
LionelVan Release Time: July 24, 2024, 6:28 AM
Nylon is termed a linear polymer because its molecular structure consists of long, repeating units (monomers) linked in a straight, chain-like formation. In the synthesis of nylon, molecules like adipic acid and hexamethylene diamine undergo condensation polymerization, where water is removed, and the monomers are bonded through amide linkages (-CONH-), forming a polymer chain. Unlike branched or cross-linked polymers, where the chains have side chains or interchain bonds that create a network structure, nylon maintains continuous, unbranched chains, contributing to its strength, flexibility, and elasticity. This linear structure is crucial for its properties, making it suitable for various applications, from textiles to engineering plastics.
