Rapid Injection Mold Tooling

This Rapid Injection Mold Tooling program shows three different methods of producing injection molds using various rapid prototyping techniques. The first example is epoxy tooling made from a stereolithography pattern that is used to mold 15 prototype parts in actual production material. The second example used the DTM process called RapidTool to make mold inserts capable of thousands of injection cycles. These RapidTool inserts were formed using powder metal in a Sinterstation. The powder metal inserts are infiltrated with copper to give the tool strength. The last example shows how the 3D Keltool process can be used to make mold inserts capable of being used as the final production tool for an injection molded part. This program also contains a demonstration of the PROMETAL machine that can make metal tooling directly from CAD data.

Holemaking

Holemaking is the most common machining operation, consuming half of all cutting tools used in chip making operations. To better understand holemaking and its various applications, this Holemaking program examines drilling basics, the drill, holemaking machines, drilling operating parameters, and hole finishing operations. The Drilling Basics segment details chip generation, high pressure coolant systems, short hole drilling, peck drilling, deep hole drilling, trepanning, EDM holemaking, and laser holemaking. The Drill segment takes an extensive look at the elements that make-up the twist drill, such as the shank, flutes, drill point, cutting lips, chisel edge, and drill web. The various drill types are also featured, including: indexable insert drills, center drills, spade drills, core drills, step drills, drilling end mills, and drill jigs. The Holemaking Machines segment explores the sensitive drill press, radial drills, self-feeding drill units, multi-spindle drilling machines, and drill & tap centers. The Drilling Operating Parameters segment presents the variables of cutting speed, feed/penetration rate, drill bluntness, and drill point grinding. The Hole Finishing Operations segment covers reaming, boring, honing, roller burnishing, counterboring, and countersinking.

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.

Plastics Finishing

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.

Cutting Tool Geometries

Efficient metalcutting requires using the properly shaped tool for the task. These cutting tools are all described by their angles or geometries. To better understand these angles, this Cutting Tool Geometries program examines single-point turning tool and toolholder geometries, and milling and multi-point tool geometries. The Turning & Single Point Tools segment explores the various aspects of tool/toolholder geometry, such as insert shape, angle of inclination, lead angle, tool nose radius, and the various cutting tool rake angles. Insert chipbreaker designs and chip formation are also covered. The Milling & Multi-Point Cutting Tools segment focuses on the various milling cutter/milling insert rake angles, as well as, lead angle, cutter pitch, hand of cutter, effective diameter and more.

Heat Treating

This Heat Treating program highlights the versatility of heat treating in altering the metallurgical properties of metals and alloys. This versatility is broken down into three groups of processes: through hardening processes, surface hardening processes and softening processes. The Through Hardening Processes segment utilizes animations, phase diagrams and photomicrographs to explain the hardening process and define its many variables. Quenching speed, quenching mediums and temperature control are examined, as well as the tempering, martempering, and austempering of heat treated materials. The Surface Hardening Processes segment offers detailed examples of the processes that produce surface, or case hardened parts. Included are explanations of: flame hardening, induction hardening, carburizing, nitriding and carbonitriding. The Softening Processes segment examines the use of annealing, normalizing and stress relieving within the heat treating 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.

Lean Manufacturing at Miller SQA

This Lean Manufacturing at Miller SQA program examines the lean manufacturing principles at an office furniture company called Miller SQA. Miller SQA has applied lean principles in a mass customization market to give their customers exactly the furniture they need when they need it. Continuous improvement is encouraged by presenting the benefits to all employees through "lean events". These lean events allow different people from all parts of the company to examine the work area and make suggestions. In addition, a pull production control system maintains inventory levels at the assembly area so no more than 2 hours worth of parts are ever in the work cell ready to be assembled. One-piece-flow, cellular manufacturing, and strong visual controls are integrated into a sophisticated information technology system to help reach the company goal of 100% on time shipment of customer orders.
