Plastic Injection Moulds for Headphones

Plastic Injection Moulds for Headphones refer to customized injection moulds specially designed and developed for plastic components of headphones (such as the headband shell and earmuff shell of over-ear headphones, the earbud cover and cavity of in-ear headphones, and the charging case shell of true wireless headphones). Their core function is to realize high-precision, integrated production of headphone components through the injection molding process, ensuring that the dimensional tolerance of components is controlled within ±0.01mm, and meeting the strict requirements of appearance texture (such as matte, high-gloss), structural strength (drop resistance, bending resistance) and assembly adaptability (seamless splicing of multiple components). Compared with general-purpose injection moulds, plastic injection moulds for headphones need to optimize the cavity design according to the characteristics of headphones such as "small size, complex curved surface, thin wall", and adapt to various headphone-specific plastics such as ABS, PC, and TPU. They are widely used in the mass production of consumer electronics headphones and are core equipment for the industrialized production of headphones.

P&M Plastic Injection Moulds for Headphones Introduction

A、Key Design Points of Plastic Injection Moulds for Headphones

The high precision and high-quality requirements for headphone components place strict demands on mold design, with core design points including:

1. Cavity and Parting Surface Design

2. Gating and Cooling System Design

3. Ejection and Positioning System Design

B、 Production Process of Plastic Injection Moulds for Headphones

1. Mould Design and Simulation

Requirement analysis: Based on the 3D model of the headphone component (such as SolidWorks model), clarify the dimensional tolerance (± 0.01mm), appearance requirements (high gloss/matte), and material characteristics (such as PC temperature resistance and TPU elasticity);

3D modeling: Use software such as UG and AutoCAD to draw a 3D model of the mold, including the cavity, pouring system, cooling system, and demolding system, with a focus on annotating key dimensions such as cavity diameter and waterway position;

2. Mould Machining and Manufacturing

Material selection: The mold cavity is made of S136 stainless steel (strong corrosion resistance, good polishing performance, suitable for appearance parts) or H13 hot work mold steel (good wear resistance, service life ≥ 500000 times, suitable for mass production); The guide column and guide sleeve are made of SUJ2 bearing steel (hardness HRC58-62);

Precision machining:

Mold cavity processing: CNC high-speed milling (speed 15000-20000rpm, accuracy ± 0.005mm) is used for initial shaping, followed by refinement of complex surfaces through electrical discharge machining (EDM, accuracy ± 0.002mm), and finally mirror polishing (Ra ≤ 0.012 μ m);

Waterway processing: Use deep hole drilling (accuracy ± 0.01mm) to process the cooling waterway, ensuring that the waterway is unobstructed and unobstructed;

Assembly: Using precision tooling positioning (positioning accuracy ± 0.003mm), assemble components such as guide columns, top pins, and hot runners to ensure that the clearance between each component meets the requirements.

3. Test Moulding and Optimization

P&M Plastic Injection Moulds for Headphones Feature And Application

As an important carrier of modern audio equipment, headphones adapt to diverse life scenarios with a variety of functions and have become an indispensable tool in people's daily lives. In terms of core functions, the first is high-fidelity audio reproduction. Whether it is a dynamic driver or a balanced armature driver, they can accurately transmit sounds of different frequency bands, allowing users to clearly capture the details of musical instruments, the texture of human voices in music, or the environmental sound effects in movies and TV dramas, thus bringing an immersive auditory experience. Secondly, the Active Noise Cancellation (ANC) function collects external noise through a built-in microphone and emits reverse sound waves to cancel it out, effectively isolating environmental noises such as the roar of subways and the hustle and bustle of offices, and creating a quiet sound space for users. In addition, the call noise cancellation function is also crucial. It can filter out background noise during calls, ensuring clear voice communication even when outdoors.In terms of application scenarios, the practicality of headphones widely covers all aspects of life. During daily commuting or when being alone, headphones serve as a personal entertainment companion. Users can listen to music, podcasts, or audiobooks through headphones to relax during fragmented time. In work and study, headphones can help enhance concentration. Noise-canceling headphones can reduce external interference, and when paired with white noise or light music, they help users quickly enter a focused state and improve work and study efficiency. In sports scenarios, lightweight sports headphones, with their sweat-proof and water-resistant design and stable fit, can accompany users to enjoy music while running or working out, and at the same time prevent equipment damage from sweat erosion. In shared spaces such as libraries and airplanes, headphones are even more of an etiquette tool. They allow users to enjoy audio content without disturbing others, maintaining the quiet order of the public environment. Furthermore, with the development of smart homes, some headphones also support voice assistant activation, enabling users to control devices through voice commands, which further expands their application scope.
