Injection Mold For The Handle Of A Hair Dryer

This high-precision Injection mold for the handle of a hair dryer, tailored by Tengrui Mould, integrates a two-cavity structure and precision slider core-pulling design to realize one-step molding of complex handles with buckles and reinforcing ribs. As a leading mold supplier, Tengrui Mould balances performance and efficiency, ensuring the mold adapts to home appliance enterprises’ mass production rhythm.

Core Selling Points

1. Complex Structure Adaptability

Integrated with slider core-pulling and angle pin mechanisms, it precisely molds complex inner handles with buckles and reinforcing ribs. One-time injection molding avoids secondary processing, directly meeting assembly requirements and reducing costs.

2. Efficient Mass Production Design

Its two-cavity layout and optimized hot runner system shorten the single injection cycle to 35 seconds, boosting efficiency. Uniform plastic flow ensures consistent two-cavity molding quality for stable mass production.

3. High Surface Quality

Cavities and cores use NAK80 steel with mirror polishing (Ra≤0.02μm), ensuring the formed handles are free of flow marks and weld lines, meeting high-end home appliance appearance standards.

4. Long Service Life and Durability

Core components adopt wear-resistant steel, reaching HRC50-54 after vacuum heat treatment. Its service life exceeds 300,000 mold cycles under normal production, reducing replacement and maintenance frequency.

Material Configuration

Tengrui Mould selects high-quality materials for each component of the Injection mold for the handle of a hair dryer, with detailed configurations as follows:

- Mold Base: S50C carbon steel, offering high rigidity and excellent machinability for stable mold structure.

- Cavity/Core: NAK80 steel, ensuring superior mirror polishing performance and deformation resistance.

- Sliders/Inserts: SKD61 steel, resisting thermal fatigue and wear in high-temperature cyclic environments.

- Guide Components: SUJ2 bearing steel pillars and bushings, ensuring precise, stable mold opening/closing.

- Auxiliary Accessories: SKH51 high-speed steel ejector pins, featuring high strength and wear resistance for smooth demolding.

Manufacturing Process

Tengrui Mould adheres to strict process standards for precise quality control of the Injection mold for the handle of a hair dryer throughout production:

1. Mold Design: 3D modeling and mold flow analysis optimize runner and cooling layouts, reducing warpage and shrinkage.

2. Precision Machining: Five-axis CNC, EDM and wire-cutting ensure cavity dimensional accuracy within ±0.015mm.

3. Surface Treatment: Cavity mirror polishing (Ra≤0.02μm); mold base nitriding for rust and wear resistance.

4. Assembly and Debugging: ≥300 consecutive test molds optimize parameters, ensuring compliance with customer standards.

Application Scenarios

This Injection mold for the handle of a hair dryer is for mass production of household/professional hair dryer inner handles, and adaptable to small appliances like garment steamers. Tengrui Mould’s factory in China has complete equipment and R&D teams, offering customized solutions.
