Here are five considerations that a hot runner supplier and a moldmaker/molder should discuss when using fiber-reinforced materials, such as those with glass filler, wood fibers (lignite in biomaterials) and wool fibers: 1) Tip selection: The key with tip selection is maintaining appropriate heat as close to the gate as possible, while maintaining a reasonable [...]
The use of CAE for injection molding simulation has progressed from flow-front prediction in the late ‘70s to full simulation of the injection molding process, its variants and associated processes. Injection molding simulation benchmarking is the comparison of predicted and actual process parameters. Typically, an extensive study is carried out on a mold, machine and [...]
Ok! I try to list some: […]
In every molding operation, there is great pressure on purchasing agents to reduce tooling costs. When looking for a quality hot runner system, it can be extremely difficult to find the best value for your investment. […]
Competitiveness and price pressure in the injection molding industry has influenced many OEMs, molders and mold manufacturers to look for new ways to survive and thrive in their regional and global markets. […]
The decision to invest in a hot runner system is a major step in reducing molding costs. Some of the major benefits of adding any type of runnerless molding technology include: reduced or eliminated regrind, decreased cycle time and improved process capability. The selection of the right system for any given application will enhance the [...]
Competitiveness and price pressure in the injection molding industry has influenced many OEMs, molders and mold manufacturers to look for new ways to survive and thrive in their regional and global markets. […]
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, […]
