Deburring Processes Introduction

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.

Painting and Powder Coating

This program begins with an introduction to the basic elements of all paint formulations including pigments, additives, solvents, and resins. Viscosity and volatile organic compounds (VOC) are also explained. The two types of resin polymer structures, enamels and lacquers, are explained with an emphasis on the crosslinking aspect of enamels.

Die Casting

Die casting is a high precision, rapid parts-production process involving the high pressure injection of molten metal into a die having a cavity of the desired part shape. This program explores the common die cast metals and their various properties, as well as die casting machines and die cast tooling.

Injection Machine Controls

The Injection Machine Controls segment features the functions of the various controls and the use of computers in mold design and construction.

The Injection Mold

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 Molding Machine

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.

Plastic Injection Molding Introduction

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.

Plastic Blow Molding

Plastic blow molding processes are the most popular methods used to produce hollow products out of thermoplastic materials. Blow molding is performed using a wide variety of production methods, including: extrusion blow molding, injection blow molding, and advanced blow molding processes. This Plastic Blow Molding program provides a detailed discussion of each of these processes, presenting a clear understanding of the similarities and differences between each of them. In addition, information on parison and preform production is provided. The Extrusion Blow Molding segment looks at both intermittent extrusion blow molding and continuous extrusion blow molding processes. The extrusion head and die assembly and machine types, such as the reciprocal screw style blow molding machine, and the accumulator style blow molding machine are featured. The Injection Blow Molding segment examines the various stations in the process, including the injector station, the blow station, and the strip, or eject, station. The Advanced Blow Molding Processes segment details both single and two-stage bi-axial stretch blow molding, and the co-extrusion blow molding processes.

Sheet Metal Bending

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.
