The first step in the mold development process—responding to a request for proposal (RFP)—requires moldmakers to import, diagnose and repair part geometry in order to assess its suitability for injection molding, develop estimates and produce a formal quote. Because moldmakers need to complete this step before even winning the business, […]
Once a mold designer has imported and repaired part geometry, moldmakers can save additional time and reduce the volume of back-and-forth communications by using a 3-D CAD package that automates the process of creating a mold model for the part, […]
A five-axis measuring head and probe system can produce impressive results in the measurement of feature-rich parts—such as powertrain components and complex, doubly-curved surfaces—including those found in aerofoils and turbine blades. […]
Examining the mold development process itself is equally important for determining how specific tools and development platforms can benefit a moldmaking operation. […]
First, this type of machine may take a beating machining graphite if it lacks the appropriate dust protection and it may not have the tight tolerance required for repositioning and redressing electrodes. The bottom line is that achieving efficiency in machining micro EDM electrodes calls for a machine dedicated to this process and designed for [...]
The latest advances in automation and combined machine technologies can bring your EDM operations forward by leaps and bounds. […]
Several operational strategies can help moldmakers increase the value they reap from their EDM processes. In wire EDM, for example, the type of wire used can cut costs and improve efficiency. Brass is a commonly used and cost-effective wire material, but zinc-coated wire can increase speeds by up to 15 percent for improved productivity. [...]
Proper preventative maintenance is crucial in keeping EDM machines running as efficiently and economically as possible. Operators need to check and maintain consumables—such as power feeders, filters and resin—regularly to prevent unstable, inaccurate machining. […]
The Total Cost of Ownership (TCO) model and analysis is commonly used to make decisions when purchasing new equipment. Part of this evaluation process should include an audit: an evaluation of current equipment and manufacturing operations to determine the capacity or capability for meeting present and future operational requirements. […]
When TCO principals are applied to major elements associated with the operation of the sinker EDM equipment, such as graphite electrode materials, the value proposition and productivity of these elements start to impact profitability of owning and operating the equipment. […]
