Monitoring of Injection Molding Tool Corrosion and Effects

Before injection molding, wood polymer composites (WPC) normally have to be dried to achieve optimal quality of the injected parts as well as to avoid corrosion of the mold. Based on a literature study, there are currently no published investigations dealing with the dependency of WPC properties on the initial moisture content of the compound's pellets. Further, it is known that water and wood Author: E. Steidl, L. Sobczak, C. Pretschuh【Get Price】

Effects of processing method and fiber size on the

01/01/2009· Wood–plastic composites (WPC) were manufactured using extrusion or injection molding (IM) and fibers with different length-to-diameter (L/D) ratios. The IM process resulted in better composite physical and mechanical properties than the extrusion process, but higher density was obtained with the extrusion process. Therefore, the differences in mechanical behavior according to processing : optometry【Get Price】

Polycarbonate lenses: Advantages and disadvantages | All

In a lens manufacturing process called injection molding, the pellets are heated until they melt. The liquid polycarbonate is then rapidly injected into lens moulds, compressed under high pressure and cooled to form a finished lens product in a matter of minutes. Trivex lenses. Despite its many advantages, polycarbonate isn't the only lens material suitable for safety applications and children 【Get Price】
