Everyone intuitively understands that milling machines, holders and tools are difficult to scale down to the microscopic dimensions and extreme accuracy needed for micro-milling. At first glance, software might seem to be an easier fit. […]
In order to achieve the quality and accuracy required in micro-milling while meeting economic constraints, the entire manufacturing chain must be optimized and synchronized. Vendors of CNC machines, cutting tools, holders, clamping tools and quality control equipment are all required to provide the right solution at a competitive cost. […]
Over the years, and more times than can probably be counted, customers call from all over to order various surface treatments for their molds, without knowing what is truly needed to make their molds run better and more efficiently. It’s surprising how many customers are talked down on services because it’s not good business to [...]
More often than not, the first question a moldmaker asks when presented with an end mill is, “How much does this tool cost?” For this, there is really only one answer, “I can tell you the price, but I cannot tell you the cost until you run the tool.” […]
A study of chinese Molders on hot runner buying criteria concluded the following: Of greatest importance to the buyer was to purchase a high quality, high performing solution that was well supported in the field, durable and dependable, delivered on time, competitive on price and featured innovative technology. […]
A continuing trend within the molding business is silicone molding, which is being used in the medical, electronics, packaging and automotive industries. […]
The design and manufacture of a silicone mold is different from thermoplastic tooling as well: e.g., tolerances, venting, part ejection and the installation of a vacuum system. Although the tooling design is different, optimizing processing variables such as temperature, pressure and time are essential in both thermoplastic molding and silicone molding. […]
Hot runners have long made processing more efficient and cost effective while improving part quality. However, in cleanroom applications, those benefits have been offset by the need to use pneumatic hot runners with slower response times and weaker closing forces. […]
While much has changed in die sinking technology, one of the foremost advancements is the development and continual improvement of adaptive control, or fuzzy logic, to eliminate the guesswork and allow the machine to take control of the metal erosion process. […]
All too often, an EDM is purchased on the premise that optimum performance will be realized regardless of the electrode material used. Part one of this article (March 2010) introduced the effect that the electrode material can have on the adaptive control of a CNC sinker. This article will describe the details of a test [...]
