Automated Composite Layup and Spray-up

This Automated Composite Layup and Spray-up program focuses on the various automated processes and equipment developed to manufacture composite products of high quality. The use of CNC gantry ply-cutters, robots, tape lamination machines and fiber placement machines are among the automated technologies detailed.

Manual Composite Layup & Spray Up

Manual composite layup and spray up are the most common methods of producing composite parts. This Manual Composite Layup & Spray Up program follows each process thoroughly, detailing each step from molds preparation through to the curing of finished layups and spray ups. The use of vacuum bag molding and autoclave molding to further consolidate layups and spray ups is also presented. This program is part of an eight program Composites Manufacturing series.

Composite Materials

This Composite Materials program features a detailed explanation of the important mechanical properties of thermoset fiber-reinforced composites. The primary types of reinforcement materials: glass, carbon and aramid are examined, as well as the major matrix materials: polyester, epoxy, bismaleimide, and polyimide. The use of thermoplastic composite materials is also highlighted. This program is part of an eight program Composites Manufacturing series.

Design for Manufacture and Assembly Introduction

Design for Manufacture and Assembly (DFMA) is a proven design methodology used to optimize part costs and quality, while reducing time-to-market development. This program features an interview with Nicholas Dewhurst of Boothroyd Dewhurst. He explains the concepts and use of DFMA in product analysis to understand the drivers of cost, and the interaction of the individual pieces within the product to optimize design, manufacturability, and assembly.

Compression Molding

The use of compression molding in high volume, high quality composite parts production is featured prominently in this Compression Molding program. The various sheet, thick and bulk molding compounds are detailed as well as mold types used. The transfer molding process, which is a technological extension of compression molding is also highlighted. This program is part of an eight program Composites Manufacturing series.

Plastic Injection Molds Introduction

The injection mold is an extremely important element of any plastic injection molding operation. Molds determine the shape of the part, vent trapped air or gases during injection, act as heat exchangers to solidify the molten plastic, and eject the cooled parts. This Plastic Injection Molds program highlights the primary injection mold components, including the mold base, cavity and cores, runner system, cooling system, and ejector system. This program also features segments on injection mold types, the use of computer simulation, mold prototyping techniques, and mold maintenance & repair.

Plastic Extrusion

The Plastic Extrusion segment explores components of the screw extrusion machine and common feedstock and materials. The two most prevalent plastic extrusion processes, profile extrusion and blown film extrusion, are also extensively detailed.

Extrusion Processes

Extrusion is the deformation of either metal or plastic forced under pressure through a die to create a shape. This unique Extrusion Processes program is an introduction to both plastic extrusion and metal extrusion processes. The Metal Extrusion segment looks at hot extrusion, press components, lubrication, force capacity, and the metals that are typically hot extruded. Both warm and cold extrusion processes are featured too, including indirect extrusion, combination extrusion, and impact extrusion. The Plastic Extrusion segment explores components of the screw extrusion machine and common feedstock and materials. The two most prevalent plastic extrusion processes, profile extrusion and blown film extrusion, are also extensively detailed.

Forging

This Forging program begins by outlining forging's function in refining the metallurgical microstructure of wrought mills forms, and it's use in generating parts to near-net shape from these forms. Featured are segments on the various types of forging processes, including: Open-Die Forging, Impression-Die Forging, and Related Forging Processes.
