Direct Gate Nozzles
Direct gate nozzles are designed for single-part and multi-material molding, where the plastic is directly injected into the mold cavity through the machine nozzle. These gates may be used in a hot runner system, where precise temperature control is required for a single nozzle and a hot tip to dispense plastic to turn into materials.
Using direct gate nozzles is ideal for producing simpler parts, as their appearance is less critical due to the sprue mark left behind. Direct side gating with these nozzles ensures efficient use of hot runner technology, providing a straightforward solution for basic applications.
Valve Gate Nozzles
Valve gate nozzles are advanced components used in hot runner systems. This type of nozzle for hot runners features a mechanical shut-off mechanism, or “valve,” that controls the flow of molten plastic resin through the single nozzle and into the mold cavity.
The valve opens to allow the plastic to flow into the nozzle tips and closes once the cavity is filled. This precise nozzle control can prevent backflow and drooling, allowing this sophisticated hot runner nozzle technology to enhance precision and reduce waste.
General Purpose Nozzles
General-purpose nozzles are versatile tools used in a variety of molding processes. Designed to handle different materials and molds, they do not have specialized features like a valve mechanism. However, their multi-material specialty does offer cost-effectiveness and ease of maintenance.
Our Polyshot hot runner nozzles are invaluable assets to hot runner systems. The hot runner nozzle lengths vary, catering to different project needs and providing an optimal match for your requirements.
Two of our prominent nozzle types are the G-050M and MS75-G. These general-purpose hot runner nozzles are widely used when forming a small sprue, which is acceptable, and they perform exceptionally well with filled materials.
Durable Hot Runner Nozzle Options
Our Polyshot hot runner nozzles, including the G-050M and MS75-G models, are built for durability and high performance. Constructed from hardened tool steel, these nozzles withstand high-pressure injection molding, extending their lifespan and reducing the need for frequent replacements.
Adaptable Nozzles for Hot Runners
Our hot runner nozzles are adaptable for use with both hot runner and cold runner systems. The nozzles can be machined to feature a .188 radius, and the G-050M and G-075M models offer principal flow diameters of .2500″, with an option to increase to .3750″.
Shipping and Customer Service

With our advanced hot runner technology and diverse nozzle options, Polyshot is dedicated to enhancing your injection molding processes and providing reliable solutions for all your molding needs.
General purpose nozzles are standard nozzles used in many basic injection molding processes. They are designed to be versatile and to work with a variety of materials and molds. A general purpose nozzle doesn’t have special features like a valve mechanism, but it is more cost-effective and easier to maintain.
G-MS75 General Purpose Nozzle
General Purpose Nozzle styles are commonly used when the formation of a small sprue is acceptable. They are often used when processing filled materials. Because the entire flow path of the nozzle is constructed of hardened tool steel, it is highly resistant to wear. They are also used when it is necessary to gate into a cold runner system. The end of the nozzle is designed to accommodate the machining of a .188 radius through it. The major flow diameter through the G-075M is .2500″, with .3750″ optional.
G-050M General Purpose Nozzle
G-050M General Purpose Nozzle styles are commonly used when the formation of a small sprue is acceptable. They are often used when processing filled materials. Because the entire flow path of the nozzle is constructed of hardened tool steel, it is highly resistant to wear. They are also used when it is necessary to gate into a cold runner system. The end of the nozzle is designed to accommodate the machining of a .188 radius through it. The flow channel size through the G-050M nozzle is .2500” diameter.
Durable Hot Runner Nozzle Options
The performance and durability of our hot runner nozzle, including variations in nozzle lengths, are of paramount importance.
The hardened tool steel construction lends to their durability and ability to handle high-pressure injection molding, extending their lifespan and reducing the need for frequent replacements.
Adaptable Nozzles for Hot Runners
These nozzles are also utilized when gating into a cold runner system is required. The nozzle’s end has been engineered to facilitate machining a .188 radius within it. The G-050M and G-075M nozzles present a principal flow diameter of .2500″. The latter has the option to increase it to .3750″.
