the Challenges and Solutions in High-Speed Machining
Success with high-speed machining requires a thorough under-standing of the required tools and methods and of their benefits and limitations. […]
Introduction to Multi-Component Molding
Two, three or four component molding can work with automation just as easy as single component. Two types are manual transfer and rotating molds. Manual transfer requires the robot end-of-arm-tooling to remove the substrate from the first cavity, remove the finished parts from the second cavity and place the substrate into the second cavity (overmold). [...]
Introduction to Stack Mold Design
Parts are removed either from the top or side of the mold (usually determined by cycle time). Be aware of mold obstructions—such as stack mold linkages, hot runner control cables and connectors, cooling hoses, etc., […]
Introduction to Insert Molding
Insert loading is an easy process if the mold is designed properly. Try to keep the insert and removal sides of the mold opposite. Insert on the mold “A” half and part removal on the “B” half. This limits the mold open time, but requires more mold open dimension. Have generous lead-ins for the inserts, [...]
Introduction to Box Filling
Mold cavity layout and quantity can be designed to allow easier robotic box or fixture loading. If the shipping container or fixture is defined, design the mold with an even increment of that container. For example, a box holds 40 parts, […]
the difference between Hot Runner and Cold Runner
Molds with hot runner or valve gate systems will simplify end-of-arm-tooling (EOAT) design and reduce cost by eliminating runner grippers or vacuum cups and allow for faster part removal. If a mold must have a cold runner, […]
What is Process Management System?
Once a pallet system has been implemented, even greater opportunities for efficiency become available. Quality process management software improves productivity by facilitating a smooth flow of information through the production floor. By attaching CMMs, EDMs and HSMs to the software, […]
What is Automation route in mold manufacturing?
Automation has been the golden key to unlocking the potential in their businesses by meeting these objectives. Moving from their more traditional manufacturing operations has not only been a major investment by these companies in dollar terms, but has also necessitated major shifts in mind-set by both management and employees. […]
How to Detect a Leak
Detecting a hot runner leak can often be difficult, as it is not always readily visible from the outside of the mold. In the worst case, plastic can be seen coming out through the electrical connectors and other openings in the system. […]
Nozzle Design Options to Prevent Leakage
There are various nozzle design options to seal between the manifold and the nozzle – (1) the solid skirt design with no active leakage prevention feature; […]
