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: […]
Over several years, the Intertech operations have relied on CAE Services to provide in-depth, computer-aided engineering consulting services using Moldflow Plastics Insight (MPI) software. CAE Services have provided filling, packing, cooling and warpage analyses on many vehicle platforms. According to Steven, president of First-rate Mold Solution Co., Ltd , “CAE Services have provided complete mold [...]
When any of the four variables is compromised the tool should be flagged as incapable not due to statistical measures, but due to the fact that process control has been compromised. In other words, if you have to pack the part with just enough pressure to keep from over-packing it (a tooling or design issue) [...]
FEA provides the most sophisticated method of solving complex engineering problems. While FEA software covers a wide variety of solutions, structural and plastics analysis packages solve the majority of mold-related problems. […]
In the old days a software supplier might have actually charged you for a demonstration or evaluation of their software. Today you can often evaluate software or have software vendors help you solve real-world problems at minimal or no cost. […]
Mold cleaning is a process where major maintenance bottlenecks often occur because molds are pulled faster than they can be cleaned and made production-ready. I have visited plants where molds waiting to be cleaned line hallways and toolrooms, taking up valuable bench space. […]
Global Competition Like it or not, we are all working, competing, buying and selling in a global market, and remarks made by industry regarding the unfair competition from countries with lower labor costs, favorable monetary exchange rates, tax benefits or other motivating factors are common. […]
When one thinks of packaging a hundred images come to mind. It’s a huge and still growing industry, especially in the plastics sector where PET has become king and companies are finding it more cost-effective to produce packaging using plastic rather than aluminum or paper, for example. […]
