This Plastic Thermoforming program highlights both cut sheet and roll fed thermoforming operations, and features details on the various thermoforming process components.

A review of the Plastics Machining & Assembly program content.

Deburring processes are used to finish sharp, undesirable part edges that are produced during cutting and stamping operations. This Deburring Processes program includes information on an array of deburring processes, including - cutting processes, power brushing, bonded abrasive finishing, mass finishing, abrasive blasting, abrasive-flow deburring, thermal deburring, and electro-chemical deburring.

Plastic injection molding is the most common method of producing parts out of plastic material. This Plastic Injection Molding program was scripted by renown plastics industry expert, Irvin I. Rubin, and focuses on the injection molding machine, the injection mold, and the injection machine controls to illustrate the injection molding process. The Injection Molding Machine segment covers in detail both the injection system and the clamping system. In step by step progression, thermoplastic material is followed from its raw material state through the melting process and onto it's injection into the mold. Throughout the sequence, various components of the injection machine are explained, including the reciprocating screw, and the various machine platens. The Injection Mold segment details and defines mold terms as the molten thermoplastic material is formed, cooled, and ejected as a final part. Also featured are the common mold types, including the two-plate cold runner mold, three-plate cold runner mold, the hot runner mold, and the insulated runner mold. The Injection Machine Controls segment features the functions of the various controls and the use of computers in mold design and construction.

This Plastics Finishing program includes information on the array of plastics finishing processes, arranging them into four categories: degating, deflashing, cleaning, and decorating. The Degating section includes segments on manual degating and the various automated tooling devices. The Deflashing section covers the cutting and trimming, media blasting and cryogenic deflashing processes. The Cleaning segment features the ways in which contaminants infiltrate the molding process and how parts are cleaned for secondary decorative operations. The Decorating section features lengthy examinations of the following processes: painting, plating, vacuum metallizing, pad printing, hot stamping, silk screening, and fill-and-wipe.

This Plastics Machining and Assembly program focuses on the primary machining and assembly processes used for plastics.

The Sheet Metal Bending segment concentrates mainly on the terms defining a bend, such as the neutral axis, bend allowance, bend radius, and springback, and focuses on the primary bending machine - the press brake. Various examples of press brake dies, gaging, and bending operations, such as air bending, and bottom bending, are shown, as well as, a segment on folding technology.

In step by step progression, thermoplastic material is followed from its raw material state through the melting process and onto it's injection into the mold. Throughout the sequence, various components of the injection machine are explained, including the reciprocating screw, and the various machine platens.

This program includes information on pattern and core production methods, and covers an array of casting processes, arranging them into three major categories: Expendable Mold/Reusable Pattern Processes, Expendable Mold/Expendable Pattern Processes, and Permanent Mold/No Pattern Processes.

This program explains the basics of composite materials and manufacturing by featuring segments on: composite matrix and reinforcement materials, composite manufacturing processes, and composite fabrication and joining methods. The first segment features the primary types of matrix and reinforcement materials, as well as the various forms in which they are available.
