With cavity steel or alloy selection, there are many variables that can dictate the best option for molds. Things that need consideration are the material you’ll be molding, cycle time expectations, part criteria, expected volume, tooling costs and maintenance. The goal here is not to suggest, recommend or give preference to any specific steel or [...]
Valve gate hot runner technology produces better-quality plastic parts and faster cycle times by offering the most accurate gate control available. Valve gate systems are also an essential tool for automated injection molding because they enable faster mold start-ups, a wider processing window, and clean gates with no stringing or drooling of melt. [...]
Much has been written and discussed relative to the cooling of mold cavities. Most molders and moldmakers are at least aware of the benefits of placing as much heat removal technology into a mold core or cavity as possible. Simply drilling a hole into the bottom of a core for a closure and inserting a [...]
Gas dwell, upon the completion of filling in the mold cavity and on the premises that the gas pressure is preserved, the product should be put aside until it gradually cools to compensate shrinkage of the product due to the cooling of materials. […]
the design also maximizes the pipelines inside the mold and thus allows rapidly raising the temperature to the thermo plastic level. […]
