Introduction to Structural Foam Molding
Structural Foam Molding is, in essence, a low pressure injection molding process. It is used to process thermoplastics, such as high density polyethylene (HDPE), in a low pressure environment. […]
Introduction to Interaction design processes
Interaction designers often follow similar processes to create a solution (not the solution) to a known interface design problem. Designers build rapid prototypes and test them with the users to validate or rebut the idea. […]
Introduction to a process of Thermoforming
Thermoforming has benefited from applications of engineering technology, although the basic forming process is very similar to what was invented many years ago. Microprocessor and computer controls on more modern machinery allow for greatly increased process control and repeatability of same-job setups from one production run to the next, usually with the ability to save [...]
Introduction to Thin and thick gauge thermoforming
There are two general thermoforming process categories. Sheet thickness less than 1.5 mm (0.060 inches) is usually delivered to the thermoforming machine from rolls or from a sheet extruder. Thin-gauge roll-fed or inline extruded thermoforming applications are dominated by rigid or semi-rigid disposable packaging. […]
What is Vacuum forming?
Vacuum forming, commonly known as vacuforming, is a simplified version of thermoforming, whereby a sheet of plastic is heated to a forming temperature, stretched onto or into a single-surface mold, and held against the mold by applying vacuum between the mold surface and the sheet.The vacuum forming process can be used to make most product [...]
Introduction to Stones
Nothing else cuts EDM faster and has a more controllable finish than a stone. While diamond files start off as being faster than stones, […]
Introduction to Steel Laps
Steel laps are the tool of choice for most polishers. Steel can be ground to any thinness and still allow for heavy downward pressure. Steel laps can be used with diamond compound or silicon carbide lapping compound as the cutting medium. […]
Introduction to Diamond Files
Diamond files are the next fastest cutting tools available for removing EDM from ribs after disking. Diamond files can be used in profilers, […]
Introduction to Brass Laps and Copper Laps
Brass laps also are very popular for lapping ribs. While not quite as rigid as steel laps, brass laps are easier to work to thickness and shape and they don’t suffer nearly as much from the deep, zigzag scoring as steel laps do. […]
How to Polish The Ultimate Rib
Take a brass lap, dress it to half the thinness of the rib, take a 220-grit, medium, hard-bond, aluminum oxide, nonoil-filled stone and slice it to half the thinness of the rib. […]
