Plastics Machining

The Plastics Machining segment highlights the use of sawing, milling, routing, turning, waterjet cutting, laser cutting, drilling and the secondary holemaking operations, such as tapping and reaming. The importance of coolant used while machining plastics is also explored in detail.

Plastics Finishing Introduction

This Plastics Finishing program includes information on the array of plastics finishing processes, arranging them into four categories: degating, deflashing, cleaning, and decorating.

Plastic Injection Molds

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. The Injection Mold Types segment showcases in detail the cold-runner two-plate mold, the cold-runner three-plate mold, the hot-runner mold, and the insulated runner mold. The Plastic Injection Mold Production segment explores the use of computer simulation to develop molds, mold production methods, mold prototyping techniques, and mold maintenance & repair.

Plastic Thermoforming Introduction

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

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.

Plastic Thermoforming

Plastic thermoforming is the process of producing parts by heating and shaping plastic sheet and film. This Plastic Thermoforming program highlights both cut sheet and roll fed thermoforming operations, and features details on the various thermoforming process components. The Thermoforming Process Components segment explores the materials, clamping systems, heating systems, thermoforming mold types, forming forces, and trimming processes. The basic thermoforming methods are also examined, including: drape thermoforming, cavity thermoforming, pressure thermoforming, plug assist thermoforming, and twin sheet thermoforming.
