the first part of the guidelines of selecting CNC or rp
Today, knowledge of CNC Machining and rapid prototyping technologies is important for the selection of the right tool for the job. […]
CNC Machining or rapid prototyping?
When comparing the merits of rapid prototyping (RP) and CNC machining, opinions abound. RP and CNC machining both have staunch supporters that tout the benefits of their preferred technology. […]
What to do a mold in Digital Manufacturing
The term digital manufacturing is starting to gain avid use in the industry; however, definitions vary. According to the Society of Manufacturing Engineers, […]
what to do a mold in Traditional manufacturing
Traditional manufacturing processes require at least an eight- to 10-week leadtime. An organization will design the projects and send it to a molder/moldmaker, […]
Why we need Rapid Prototypes before Moldmaking?
There are three powerful steps to im-proving moldmaking power and those who have implemented these steps are well on the way to becoming the ultimate toolmakers in their industry. […]
Introduction to Current Nozzle Technology
Problems with some hot runner technologies are that heat loss through the nozzle can be 40 percent. The heater overheats plastic at the middle of the nozzle. […]
How do you go about evaluating hot runner nozzles?
How do you go about evaluating hot runner nozzles? First, evaluate the entire molding system—including part design, plastics material, part weight, cycle time, mold, runner, gates (valve or thermal), nozzles, temperature control and molding machine characteristics. […]
We can do Injection Molding in computer
Moldflow Plastic Insight (MPI) is a computer simulation of injection molding that “helps us begin to understand what is going on inside the mold,” […]
Electric Valve Gating in hot runner system
Hot runner systems have traditionally used either pneumatic or hydraulic actuation to open and close valve gates. […]
Thinner Walls and Higher Outputs need hot runner system
In food packaging, the trend has been toward increasingly thinner walls and higher outputs. To accommodate this trend, […]
