Through our rich experience and perfect supply chain, our company can provide customers with high-quality customized custom injection plastic parts moulding products to meet their specific needs. At the same time, we have 10 years of professional foreign trade service experience, understand the foreign trade process, and better serve our customers. For custom injection plastic parts moulding products, we can make corresponding plastic parts, which is mainly done through injection molds.

Phase One: In-depth Demand Collaboration and design Definition

This is the "defining the soul" stage of the project, which determines the product's DNA.

Three-dimensional demand locking

Acoustic objectives: The type of headphones (in-ear, over-ear), tuning style, and speaker unit specifications determine the internal structure of the cavity, the design of the sound guide tube and the pressure relief hole.

Wearing and interaction: Wearing comfort, stability, weight target, control method (buttons/touch).

Appearance and brand: ID design language, color/texture, and the way brand Logo is integrated.

Multidisciplinary Collaborative Design and DFM

Acoustic structure design: Collaborate with acoustic engineers to optimize the internal structure of the cavity and the airflow channels, which is the physical basis for good sound quality.

Ergonomic design: Based on big data of the auricle, the fitting curve is designed to ensure comfort and sound insulation.

Precision structural design: Design precision clips, screw columns, and cable trays to serve subsequent assembly.

Selection of materials science

Cavity/head beam: ABS (superior comprehensive cost), PC/ABS (high toughness and high gloss), metal/plastic composite (high-end texture).

Earplugs/skin-friendly parts: TPE/TPU/Silicone (medical-grade soft rubber, for comfort and sealing).

Transparent decorative pieces: PC or PMMA (acrylic, used for translucent logos).

DFM output: Provide a detailed report including wall thickness, draft, and assembly tolerances, and confirm with the customer.

Phase Two: Precision Mold Engineering

Molds are the "high-fidelity translators" for realizing designs.

Mold flow analysis: Mandatory execution. Analyze the core appearance components and complex structural components, predict and solve problems such as weld lines, shrinkage and deformation to ensure dimensional stability and perfect appearance.

Mold design and processing

High-gloss/etched mold: The surface cavity of the appearance needs to be mirror-polished (VDI A0 grade) or finely sunburned (such as leather, matte texture).

Microstructure processing: Use "mirror EDM machine" and "five-axis precision milling machine" to process tiny acoustic holes and fine clips.

Multi-material mold

Two-color/multi-color molds: used for the combination of hard rubber/soft rubber or the one-piece molding of different colors.

Rubber-coated mold: First, soft rubber is injected onto a hard frame to achieve a seamless and comfortable feel.

Clean and dust-proof design: The mold design should take into account its use in a 10,000-level dust-free workshop and be equipped with a dedicated dust cover.

Phase Three: Clean injection Molding and secondary processing

Injection molding in clean workshop

Environment: Produced in a 10,000-level / 100,000-level dust-free injection molding workshop to prevent dust contamination.

Key points of the process

The materials are strictly dried to prevent silver streaks and bubbles.

High mold temperature process: High mold temperatures (such as 65-80℃ for ABS) are applied to the appearance parts to achieve the ultimate gloss and reduce internal stress.

Automated production: Mechanical arms automatically pick up items, avoiding scratches or contamination caused by hand contact.

High-end secondary processing

Spraying: UV spraying, rubber paint spraying to enhance the hand feel and texture.

Electroplating/vacuum plating: Achieve metallic luster.

Laser engraving/silk-screen printing: Engraving logos, light transmission holes for indicator lights.

Fabric/leather covering (for over-ear headphones).

Phase Four: Strict quality inspection throughout the entire chain

The testing standards are much higher than those for ordinary consumer electronics.

Optical-grade appearance inspection

Automated visual inspection: 100% visual inspection is carried out using AOI equipment to identify micron-level defects such as scratches, dirt spots, and shrinkage.

Color difference control: Compare with the customer-provided color palette under a standard light source box, and quantify the data using a color difference meter.

Precision dimensional inspection

The key assembly dimensions and surface contours are inspected using a three-coordinate measuring machine and a laser scanner.

Function and reliability testing

Acoustic testing: Test the frequency response curve and distortion on standard artificial ears/simulated ears to ensure that the sound quality meets the design goals.

Wearing test: Test the wearing stability, comfort and sound insulation effect through real people or simulated headmodels.

Durability tests: tens of thousands of life tests such as head beam stretching, key clicking, interface plugging and unplugging, etc.

Environmental tests: high and low temperatures, humidity, and sweat corrosion tests.

Phase Five: Finished product assembly and delivery

Dust-free workshop assembly: Speaker units, PCB mainboards, batteries, injection molded parts, etc. are assembled into finished products in a dust-free workshop.

Final inspection and packaging: After conducting the final functional tests, high-protective custom packaging is used.
