the fifth principle for deciding on the parting line is easy to machining. For instance, a slanted parting line and a curved parting line, […]
as for coarse lead screws, I have more details, during the demolding process, how to drive the cores, yes! The opening movement of the molding machine is transformed into a rotary action, […]
what about molds with coarse lead screws? I think, that is the most simplest driving method, because nuts mounted in the machine is the most reliable elements for thread-forming cores. And we can save setup time and special control of the stroke.
I want to say some thing about unscrewing mold with rack. In these molds, the diameter of part, the force of the machine or the rack drive limit the number of threads that can be molded, and the opening movement of the machine or a separate hydraulic or pneumatic actuator can actuate the stroke.
As a professional mold maker, more information must be at hand when you evaluate a mold project,they include the machine we will run in, the number of cavities required, the type of plastic that will be used for this product. And so on.
Machine controls today allow for extensive dynamic tuning of machine performance. The most common values to look at when considering machine dynamics are speed and acceleration. Equally important as each of these is jerk. […]
A moldmaker typically creates simple subplates with dozens, even hundreds, of holes that must be drilled, bored and tapped. Using conventional CAM to program all of these features for manufacturing on a CNC mill could take several hours. Today, he can import a model of the subplate from his CAD program, bring it into the [...]
Choosing an online course, so employees can take it at their own pace can be vital to retaining the knowledge long-term. They will need to build on their knowledge; otherwise it is limiting their potential. An online course should make every single machinist an expert in their trade. Every machinist should have a basic knowledge [...]
Robotics in machine tending can cut costs dramatically by allowing skilled labor to focus on imperative production tasks. In automated machine tending the robot loads and unloads parts from the CNC machine. Using standard part holding fixtures simplifies the production setup as the robot always handles the fixture instead of the actual part. […]
Gas permeable mold steel can be machined by conventional methods using cutoff saws, end mills, grinders, EDM, stoning, etc. It is important to remember that this material is honeycombed with thousands of microscopic holes, which are affected by metal removal. Oil coolant is recommended. […]
