There are many hot runner manufacturers and product lines, but a typical hot runner system is made up of:

(1) manifold

(2) Nozzle

(3) Temperature controller

(4) Accessories

Advantage

• Potentially faster cycle times.

Save materials. No material wasted. Plastic materials are expensive, which makes a lot of sense for engineering.

• Improve the quality of molded parts. Parts formed from hot runners usually have a good appearance quality.

• No robots or people are needed to eliminate athletes.

• Can accommodate larger parts.

Disadvantage

• Higher mold costs

• Color cannot be easily changed

• Higher maintenance costs and potential downtime

• may not be suitable for certain heat sensitive materials
