hot runner buying criteria concluded the following: Of greatest importance to the buyer was to purchase a high quality, high performing solution that was well supported in the field, durable and dependable, delivered on time, competitive on price and featured innovative technology. […]
The torpedo system is one of the first hot runner heated nozzles introduced to the moldmaking industry. The concept is simple – a cartridge heater is inserted into a gun-drilled hole running through the center of several flow channels. […]
Coil heaters have been introduced to the hot runner system – greatly increasing the cycle speed and the quality of the product produced. […]
Cartridge heaters are utilized around the flow channel to ensure uniform temperature. It is important to keep the distance between the heaters and the manifold equal or greater than 1x the diameter of the heating. […]
A new mold temperature control technology has been developed that affects the two most important things in mold cooling: flow rate and temperature. […]
Tubular heating elements are inserted into a milled slot into the manifold. This allows for a more accurate location of heat at the areas that require the most . […]
Thermal Load StabilityOxidizing decay of organic components in thermal insulation boards increases with rising temperatures. Continuous thermal load is defined by the temperature at which the application of a particular grade can be technically and economically justified, so that the lifetime will extend to several years. […]
“I’m a great moldmaker. I know my trade. My company has great people, the best equipment and we can cut anything. […]
Selecting the right heater for a molding application is critical to the success of any operation. The most common heating elements specified for use in molds are cartridge, tubular and strip heaters. […]
When more than one gate is required within a system, the question of balance is raised. When running multicavity molds, it’s important that all the gates perform identically. This is especially true when molding highly toleranced and thin wall components. […]
