## Abstract

A nozzle-locating insulator (300), comprising: a body assembly (302), having: a spring-facing surface (304) including: spring-contact sections (306); and spring-noncontact sections (308) interposed between the spring-contact sections (306).

## Claims

### Claim 1

A nozzle-locating insulator (300), comprising:
a body assembly (302), having:
a spring-facing surface (304) including:
spring-contact sections (306); and
spring-noncontact sections (308) interposed between the spring-contact sections (306).

### Claim 2 (depends on 1)

A mold-tool system (100) having the nozzle-locating insulator (300) of claim 1, the mold-tool system (100) comprising:
a molding-nozzle assembly (102);
a spring assembly (112);
the body assembly (302) defines a central passageway (309) is configured to receive the molding-nozzle assembly (102);
the spring-contact sections (306) of the spring-facing surface (304) contact the spring assembly (112);
the spring-noncontact sections (308) of the spring-facing surface (304) set apart from the spring assembly (112), the spring-noncontact sections (308) reducing surface contact with the spring assembly (112) so that thermal losses are reduced from the molding-nozzle assembly (102) through the nozzle-locating insulator (300) and the spring assembly (112).

### Claim 3 (depends on 2)

A molding system (200) having the mold-tool system (100) of claim 2.
