Today’s popular CAD systems share a common technical foundation in the way solid (and surface quilt) models are internally described and represented. Of course, the specifics differ from one system to another, which gives rise to the very challenges that face interoperability. Modern modeling systems define a 3-D object by its topology and geometry. [...]
Thermal Load StabilityOxidizing decay of organic components in thermal insulation boards increases with rising temperatures. Continuous thermal load is defined by the temperature at which the application of a particular grade can be technically and economically justified, so that the lifetime will extend to several years. […]
Heater SelectionSelecting the right heater for a molding application is critical to the success of any operation. The most common heating elements specified for use in molds are cartridge, tubular and strip heaters. […]
Over the years, heating systems for hot runner systems have changed as much as hot runners themselves have. The word “hot runner” itself explains the process and keeping the runner hot is a simple idea. […]
Software has become a fact of life in American manufacturing. CAD/CAM requirements differ among companies, so it’s not surprising that many find it necessary to customize their systems to meet their particular needs. […]
Manufacturers continuously strive to develop better mousetraps for their production needs. For Bell Labs, this isn’t just a figure of speech – it’s literal. The Madison, WI, company has been supplying rodent traps to the professional pest control market for more than 25 years. Bell Labs’ two latest `better’ mousetraps are the result of a [...]
Three dimensional-based mold design solutions are being used for the development of injection molds, allowing mold tooling companies to shorten their development times and automate mold manufacturing. Also with 3-D, the quality of the design gets better because of the excellent possibilities to analyze the design. […]
Much like the hot runner market, the components sector also has seen faster delivery times. Steven president of first-rate mold company , points out that in addition to quicker deliveries is less expense—with quality a given. “The industry is much more open-minded and single sourcing is now a rarity as there are many innovative good [...]
In every molding operation, there is great pressure on purchasing agents to reduce tooling costs. When looking for a quality hot runner system, it can be extremely difficult to find the best value for your investment. There are so many considerations to choosing the right solution that it may seem easiest to “stick with what [...]
Valve Gates/NozzlesThe use of more valve gate technology over the years is an eminent trend. “Valve gates provide better control over the injection molding process and generally, better quality parts,” steven, president of first-rate mold company explains. “This technology has always been used in high end markets like medical, but it is now finding its [...]
