There are few applications in which materials quality is more important than in the production of polycarbonate ophthalmic lenses. The slightest variation from perfection can alter the prescription ...

About 50 billion plastic screw caps are made annually, and demand is rising all the time. In the game between the two rival production processes, neither holds all the aces. When it comes to choosing ...

At the upcoming Fakuma show in Germany, Netstal will present what company officials are calling a world's first: injection-compression molding on stack molds. Fakuma is set for Oct. 13-17 in ...

In addition to its considerably higher cost-effectiveness, the process has the great advantage that as well as the high pressing forces that can be achieved, temperatures above 450° can also be ...

Huntsman Advanced Materials (Basel, Switzerland) reports that it has developed a new epoxy resin system and a novel and cost-efficient compression molding concept. By combining a new fast-cure ...

Shindo noncrimp fabrics (NCFs) have been used for various products in the aerospace, marine, civil construction, and repair and reinforcement fields. There are four features that characterize this new ...

Injection overmolding of unidirectional fibers and preforms is an attractive process for many good reasons. It’s fast, consistent and repeatable, and it can be performed with a machine that is ...

In this study, experiments and mold flow simulation results are presented for a void-free wafer level molded underfill (WLMUF) process with High-Density Fan-Out (HDFO) test vehicles using a ...

Compression molding involves forming of complex shaped components by molding of a charge of fiber reinforced prepreg bulk molding compound (BMC) under heat and high pressures. Unidirectional fiber ...

Today’s fan-out wafer-level packaging (FOWLP) processes use organic substrates composed of epoxy mold compound (EMC) created using a thermal compression process. EMC wafers are a cost-effective way to ...
