Hot Runner Nozzle Tips

YAO Precision manufactures custom hot runner nozzle tips and related precision components according to customer drawings and specifications. Our build-to-print precision machining services support mold manufacturers, hot runner component suppliers, and OEM teams requiring application-specific geometries, controlled fits, and carefully finished surfaces.

From nozzle bodies and valve pins to sprue bushings and mold inserts, we provide custom manufacturing for components that require more flexibility than standard catalog parts can offer.

Build-to-Print Precision Machining for Hot Runner Components

We manufacture special hot runner and mold components to the dimensions, materials, heat treatment requirements, and surface specifications defined in your drawings.

Our custom component range includes:

• Hot runner nozzle tips and replaceable tip inserts

• Hot runner nozzle bodies

• Hot runner valve pins

• Sprue bushings and injection bushings

• Runner guide components

• Related core inserts and cavity inserts

Our manufacturing capabilities cover material sourcing, turning, milling, precision grinding, Wire EDM, die-sinking EDM, heat treatment, and surface treatment, with the process route selected according to each component’s requirements.

Whether your project involves a new mold or a replacement component, we review the drawing requirements to establish a suitable manufacturing approach.

Custom Hot Runner Nozzle Tips for Your Mold Design

Hot runner nozzle tips must fit the requirements of the specified nozzle and gate assembly. We manufacture customer-designed tip geometries, mating features, threads, and internal passages where required by the drawing.

Your specifications can define the critical dimensions and surfaces associated with gate position, allowable gate vestige, shot weight, and cavity spacing. These application requirements guide component manufacturing, while overall molding performance depends on the complete hot runner system and processing conditions.

Where the customer’s design incorporates replaceable tips or front-access installation, we manufacture the corresponding interfaces to the specified fit and assembly requirements.

Hot Runner Sprue Bushing and Related Components

For projects requiring a custom hot runner sprue bushing, YAO Precision provides machining to the specified bore profile, locating diameter, seating surface, and connection geometry.

We also manufacture associated nozzle bodies, valve pins, and runner guide components. Drawing-based production allows the dimensions and interfaces of each part to follow the requirements of the intended mold assembly.

Material, hardness, dimensional tolerances, and surface finish are reviewed against the application and customer specifications.

Precision Parts for High-Cavitation Molds

High-cavitation mold projects require close attention to consistency across repeated components. Our manufacturing service supports customer-defined requirements for matching dimensions, locating features, mating surfaces, and finished profiles.

For multi-cavity projects, drawings should identify the dimensions that are critical to assembly and any requirements for matching, cavity identification, or replacement interchangeability.

By manufacturing to these defined requirements, we help mold builders obtain components suited to their assembly and maintenance plans.

Core Insert and Cavity Insert Manufacturing

We support core insert and cavity insert projects alongside hot runner component manufacturing. Depending on the drawing, production may combine turning, milling, precision grinding, and EDM to create the required profiles and fitting features.

Coordinating the specified dimensions of inserts and adjacent components helps support accurate mold assembly. Critical fits, alignment features, and surface requirements should be clearly identified during the quotation stage.

Materials and Surface Requirements

Available material options include customer-specified grades such as SUS440C, STAVAX, SKD61, and SKH51, subject to procurement and manufacturing review.

Material selection is evaluated for each component rather than applied uniformly across the entire hot runner assembly. Please specify the required grade, hardness, heat treatment, coating, and surface finish when submitting your inquiry.

Precisely manufactured fits and appropriately finished surfaces can help manage wear and support tooling service life when combined with suitable materials, mold design, and operating conditions.
