Таблетки 1: The OEM Partnership Framework – From Concept to Commercialization

The journey begins long before production, rooted in a structured and transparent partnership.

1.1. Initial Consultation and Design Finalization

• Client Vision Translation: JINGYING’s design team works with the client to translate mood boards, эскизы, or concepts into a manufacturable design. For oil drop hoops, this involves defining critical aspects:

  • Пропорции: The diameter of the hoop, the size and shape of the oil drop element, and the overall scale.

  • Стиль: Is the design minimalist with a smooth surface, or does it incorporate texture, millgrain, or stone-setting on the drop?

  • Clip-On Mechanism Integration: The design must aesthetically incorporate the mechanism without compromising the design’s flow.

• Technical Feasibility Analysis: JINGYING engineers analyze the design for potential issues in casting (НАПРИМЕР., weak points), отделка (НАПРИМЕР., hard-to-reach areas), и покрытие (НАПРИМЕР., ensuring even coverage on the mechanism).

1.2. The Prototyping Phase: Validating Design and Function

• CAD Modeling and 3D Printing: A precise 3D model is created, allowing the client to visualize the earring from every angle. A resin prototype is often printed for a tangible review.

• Functional Prototype in Metal: This is the most critical step. A prototype is crafted in brass or silver to test:

  • Aesthetics: The proportion and drape of the hoop and drop.

  • Comfort and Function of the Clip: The tension of the clip must be secure enough to hold the earring firmly in place but not so tight as to cause pain. The paddles must sit flush against the earlobe. This requires iterative adjustments.

  • Масса: The earring must be lightweight enough for all-day comfort, a key consideration for clip-ons.

• Одобрение клиента: The client signs off on the functional prototype, making it the “Золотой стандарт” for all future production.

1.3. The Technical Package (Tech Pack) – The Manufacturing Bible
Once approved, every detail is documented in a Tech Pack, which includes:

• Engineering Drawings: With exact dimensions, tolerances, and angles for the hoop, drop, and clip assembly.

• Характеристики материала: Mandating the specific sterling silver alloy and the composition of the rose gold plating (НАПРИМЕР., the ratio of gold, медь, and silver to achieve the desired rose hue).

• Plating Specification: Defining the minimum thickness (НАПРИМЕР., 3.0 Микроны) and required evenness.

• Approved Sample: Photographs and a physical sample of the approved prototype.

Таблетки 2: Deconstructing the Manufacturing Process and Cost Drivers

The OEM price is a direct reflection of the complex processes involved.

2.1. Материальные затраты

• серебро 925 пробы: The base metal for the entire earring, including the clip mechanism. The cost is based on the weight of the silver, which is determined by the thickness of the hoop and the size of the drop.

• Розовое золото Вермейл: The cost of the rose gold layer is calculated based on the surface area of the earrings and the plating thickness. Achieving a consistent rose color requires precise control over the electroplating solution’s chemistry.

• Components: For clip-ons, high-quality internal springs and hinges may be sourced from specialized suppliers, adding to the cost.

2.2. Manufacturing and Labor Costs (The Core Value-Add)

• Model and Mold Making (NRE Cost): Creating the master model and casting tree for the intricate hoop and drop components. This is a one-time cost.

• Кастинг: Using the lost-wax casting method to produce the raw silver components. The fluid shape of the oil drop requires expert casting to avoid porosity.

• Сборка и паялка: The oil drop element must be meticulously soldered onto the hoop. The clip mechanism must be assembled and soldered onto the back of the hoop with extreme precision to ensure proper alignment and function. This is a highly skilled task.

• Отделка и полировка: This is exceptionally labor-intensive for this design. Polishers must painstakingly finish the entire surface, including the inner curve of the hoop and the entire contour of the oil drop, to a high shine without altering its delicate shape. The clip mechanism must be polished smooth to avoid snagging.

• Гальванизация: Applying the rose gold vermeil layer. The earrings must be racked carefully to ensure current flows evenly to all parts, including the recessed areas of the clip mechanism. Pulse plating technology is essential for a consistent, pore-free deposit on such a complex shape.

2.3. The Clip-On Mechanism: A Specialty Cost Center
This is the most technically challenging aspect and a significant cost driver.

• Engineering: The design of the mechanism requires expertise in tension and leverage.

• Точное производство: The components must be cast or stamped with extreme precision to ensure a perfect fit and smooth operation.

• Hand-Assembly and Calibration: Each clip must be assembled and adjusted by hand to achieve the perfect balance of hold and comfort. This calibration cannot be automated.

• Тестирование: Each mechanism must be tested repeatedly for function and durability.

2.4. Overhead and Quality Assurance

• Контроль качества (QC): A massive, non-negotiable cost. Это включает в себя:

  • Function Testing: Every single clip is tested for tension and security.

  • Визуальный осмотр: 100% inspection under magnification for plating flaws, polishing marks, and soldering quality.

  • XRF Verification: Testing a statistical sample from each batch to verify rose gold thickness meets the 3.0+ micron standard.

• Р&Дюймовый, Administration, and Profit Margin.

Таблетки 3: The JINGYING Quality Assurance Protocol for Clip-On Vermeil

Maintaining standards for this product requires a specialized QA focus.

3.1. Процедуры

• Post-Casting: Inspection of raw components for porosity, especially on the thin parts of the hoop and drop.

• Post-Assembly: Checking the solder joint for the drop and the alignment of the clip mechanism.

• Pre-Plating: Verifying the surface is perfectly polished and free of scratches.

3.2. Final Inspection Regime
Every single pair of earrings undergoes:

• Comfort and Function Test: An inspector wears the earrings for a short period to subjectively assess comfort and security.

• Mechanical Function Test: The clip is opened and closed 50+ times to test for long-term durability and consistent tension.

• Aesthetic Inspection: Under 10x magnification, inspectors look for any plating inconsistencies, color mismatches between the two earrings, and microscopic defects.

• Weight and Matching: The two earrings are weighed to ensure they are a matched pair within a strict tolerance.

3.3. А “Wear Test” Batch
Before shipping a large order, JINGYING should conduct a extended wear test on a sample batch from the production run, having team members wear the earrings for several days to identify any potential issues with comfort, plating wear, or mechanism fatigue that might not be caught in a standard inspection.
