Composite Materials and Manufacturing

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.

Plastics Assembly

The Plastics Assembly section covers the many fastening and joining methods used to produce plastic parts. Included are segments on snap-fit fasteners, the use of hinges, mechanical fasteners, adhesive and solvent bonding applications, and the various plastic welding processes, including: spin welding, hot-gas welding, ultrasonic welding, vibration welding, heat staking and ultrasonic staking.

Sheet Metal Shearing and Bending

This program examines two of the oldest manufacturing processes: shearing and bending. Shearing is the cutting of sheet metal by means of two opposing blades. It is used to cut large sheets of material into smaller more manageable sections. Bending is the creation of three-dimensional shapes out of two-dimensional material, and is a fast, economical way to produce an endless variety of parts from sheet metal and plate.

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.

Plastic Injection Molding

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.

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.
