A hot runner system produces plastic molds through a process known as injection molding. The nozzle of a hot runner system is the interface between the cavity and melt delivery system and is used to feed the molten plastic into the cavity of the mold.
Different Types of Hot Runner Nozzles
Direct Gate Nozzles
The Direct Gate Nozzle specializes in preventing nozzle leakage using H-13 steel. Its single-piece design eliminates stresses and leakage that can occur with multi-piece designs. This type of hot runner nozzle is often used in applications producing caps/closures and consumer electronic molds.
The Power Point® Valve Gate Nozzle is internally heated, providing a uniform heat profile and offering a flow of plastic into the cavity. This eliminates blemishes that can occur with uncontrolled plastic flow. This type of hot runner nozzle is often used in medical applications where precise parts are required.
Edge Gate Nozzles
The Power Point® Edge Gate Nozzle is designed for high-volume production and caters to resins where the gate is on a sidewall, allowing you to directly gate on the side of the part. This eliminates the need for cold runners. This type of hot runner nozzle is often used in the production of medical and thin wall packaging molds, including syringes, pipettes, and hygiene products.
The Cluster/Multi-Tip Nozzle includes multiple tips, and its compact size is ideal for the production of complex, small sparts that require multiple gates in confined areas. As with the Direct Gate Nozzle, the Cluster/Multi-Gate Nozzle is often used in the product of medical and caps/closure applications.
The Equatemp® Molding Machine Nozzle is a patented design that provides high-performance, precise temperature control, and burn-out resistance. The use of ceramic-insulated resistance wire ensures the highest possible heat transfer rate. This results in a longer heater service life. The nozzle body utilizes H-13 tool steel for maximum durability.
