There are numerous software solu-tions available for real-time, CAD-based measuring metrology. Each one has strengths and shortfalls that distinguish them from the others. Key aspects to consider when looking for the best solution are: […]
CMM is constructed very differently than a machine tool, so maintenance requirements are also very different. Below, are some maintenance tips to help you obtain maximum life and performance from your CMM: […]
Today’s standard machine tools can deliver accuracy and repeatability approaching levels formerly available only on CMMs. This enables the machine tool itself to be used for probing checks of workpieces during critical stages of the machining process. […]
The degree at which a nozzle needs to be cleaned is dependent upon the clearance around the nozzle body and the cavity insert along with the sealing/stacking surfaces of the components. […]
Now we discuss the pros and cons of sending a flashed manifold out for repair versus performing this task in-house. This article will begin to deal with the disassembly, troubleshooting, cleaning and reassembling of a typical, and flashed 16-cavity valve gate manifold. […]
If there is even the slightest suspicion that a manifold has flashed, the processor should put a few pellets of a red resin or contrasting colorant into the melt stream (in the nozzle tip), then shoot the mold two to four times before it’s pulled to aid in locating the source of the leak. While [...]
Most shops use gage balls during the inspection process, but First-rate Mold Solution Co., Ltd felt the results weren’t always repeatable. According to Steven, the balls are usually a jig ground hole in a workpiece with a reference point customer-specific to each item. We needed a process that guaranteed repeatable results. […]
1. Flow RateFirst, flow rate must be established. How is this usually done? Is it even studied at all? The answer is “It isn’t studied.” The sad fact is that it is so easy to do. The injection molding machine itself is the most available and easiest rheometer there is to use. […]
Mold builders and their customers have long applied themselves to the digital technology afforded by CAD and CAM. These technologies have been employed in design as well as manufacturing and include CNC machining, routing, EDM and other processes. But those aspects of the enterprise are not the only ones that are open to great benefits [...]
Not all problems require the expense and complexity of FEA software. You can calculate many common mold design problems with programs that only require you to enter sizes, forces or other known quantities, including the following: […]
