Cronología del cepillo de dientes eléctrico OEM: Guía del proceso semana a semana (2026)

Empieza la primera semana escribiendo un Solicitud de presupuesto (RFQ) y enviarla simultáneamente a 4-6 fábricas. La calidad de la petición de oferta determina la calidad de los presupuestos que recibirá. Las solicitudes imprecisas obtienen respuestas imprecisas y precios inflados que no se hacen evidentes hasta más tarde.

• Define product specifications: Drive technology and specified motion metric, battery voltage and capacity/Wh, applicable ingress-protection target, handle dimensions, brush-head type, charging method, and operating modes.
• Establezca sus cantidades objetivo: Indique la cantidad de su pedido inicial y el volumen anual previsto. Las fábricas fijan precios diferentes para 500 y 5.000 unidades
• List destination-market compliance requirements: identify applicable product rules and evidence for the model and configuration; confirm testing and documentation with the laboratory or qualified adviser.
• Especifique los requisitos de embalaje: Dimensiones de la caja minorista, tarjeta de inserción, caja principal, requisitos de etiquetado Amazon-ready
• Identificar 4-6 fábricas candidatas: Utilice los directorios de la Feria de Cantón, el filtro de proveedores de oro de Alibaba, Made-in-China.com o referencias directas.

Compare quotations on identical specifications, quantity, Incoterms, testing, packaging, and documentation. Assess total landed cost and assumptions; price alone does not establish supplier quality or future rework cost.

• Compare presupuestos sobre la misma base: Confirme que todos los presupuestos utilizan los mismos Incoterms (normalmente FOB Shenzhen), incluyen las mismas certificaciones y cubren idénticas especificaciones de embalaje.
• Verify the supplier: Check its business registration and any claimed ISO 9001 certificate. For comparable products, request model-specific test reports and conformity documents relevant to your target market. CE is a conformity mark; FCC requirements depend on the product configuration.
• Evalúe la velocidad de comunicación: Track response times during evaluation and agree on communication expectations and escalation contacts before production.
• Solicitar perfil de fábrica: ¿Cuántas líneas de producción? ¿Capacidad anual? Principales clientes actuales (anónimos) ¿Han exportado antes a su mercado objetivo?
• Shortlist suppliers for further review. If needed, commission a scoped factory audit and obtain a current quotation from the provider.

After scope and commercial terms are agreed, engineering reviews design, tooling, materials, assembly, and available processes. The number of questions and response time depend on the project.

• DFM review: Ask engineering to identify design, tooling, assembly, and process questions and document any proposed changes.
• Review proposed CAD and tooling designs before authorizing fabrication. Changes after work begins may affect engineering, time, and cost; define approval and tooling ownership in writing.
• Confirmación de material: Confirme el material del mango (ABS / PC / mezcla de ABS+PC), el material de las cerdas (nylon / DuPont Tynex) y las especificaciones del sobremoldeado de TPE/caucho.
• Document the relevant vibration or brush-head movement metric and test method; distinguish VPM, Hz, and rotational speed. Do not call sonic operation ultrasonic without supporting frequency data.
• Tooling cost and payment timing depend on design and contract. Agree amount, ownership, acceptance milestone, and payment triggers in writing.

During mold fabrication, request updates at agreed milestones. Toolmaking requires inspection and adjustment; the appropriate correction depends on the issue and engineering assessment.

• Tooling lead time and durability depend on design, material, process, workload, production conditions, and maintenance. Obtain a project-specific estimate.
• Solicite fotos del progreso: Solicite fotos de mecanizado CNC en la terminación 50% y 100%
• Tareas paralelas durante esta espera:
  • Finalizar el logotipo de la marca y la paleta de colores para la textura del molde
  • Borrador del diseño del envase de venta al por menor para su revisión en fábrica
  • Ask your testing lab to review the rules and test scope for the intended product and destination markets.
  • Prepare importer-of-record arrangements if required for the destination and transaction.
• Tool life depends on grade, heat treatment, mold design, resin, production conditions, and maintenance; quoted shot counts are not universal guarantees.

A first mold trial (often called T1) evaluates molded parts and fit. It may identify dimensional, surface, or assembly issues and is not necessarily a complete functional product.

• Inspección dimensional T1: La fábrica mide las dimensiones críticas comparándolas con los planos aprobados mediante MMC (máquina de medición por coordenadas) o calibres.
• Revisión del acabado superficial: Compruebe la textura, el nivel de brillo, la visibilidad de la línea de separación y cualquier marca de hundimiento o línea de soldadura.
• Ensayo de la asamblea: Las mitades de la carcasa se ensamblan con los componentes internos (PCB, motor, batería) para comprobar el ajuste y el apilamiento de tolerancias.
• T1 findings and corrective actions:
  • Inspect flash, sink marks, weld lines, fit, and surface texture against the drawing and sample criteria.
  • Ask engineering to identify root cause before approving a design, process, or tooling change.
  • Record corrective actions and re-trial timing in the project schedule; no single repair or turnaround applies to every case.
  • Review the updated sample before approving the next stage.
• Solicite el envío físico de muestras T1: Incluso con fotos, la evaluación práctica revela cosas que una cámara pasa por alto. Calidad táctil, distribución del peso, sensación de los botones

The pre-production sample should represent the agreed design closely enough for review. Define tests, sample size, conditions, acceptance criteria, and any changes requiring reassessment.

• Functional sample testing:
  • Battery runtime: Define sample, charge state, operating mode, load, and stop criteria. One condition does not establish runtime for every mode or battery.
  • IPX7 immersion: Use applicable IEC 60529 conditions, commonly 1 m for 30 minutes for the relevant enclosure. Longer duration is not an IPX7 requirement; an air-pressure screen is not the water test.
  • Prueba de caída: Agree sample, height, surface, orientations, repetitions, and pass criteria in the project protocol.
  • Brush-head attachment: Define sample, cycle count, and evaluation criteria in the product specification.
  • Charging/cycle test: Specify charger, battery, cycle count, measurements, and acceptance criteria.
  • Vibration measurement: Document instrument, measurement point, method, and metric; distinguish sonic vibration from ultrasonic frequency and rotational speed.
  • Temperature test: Define product state, exposure duration, operating condition, and criteria; limited testing does not prove all-environment performance.
• Revisión del prototipo de envase: Compruebe los colores impresos de la caja de venta al por menor (solicite una prueba exacta de Pantone), la posibilidad de escanear el código de barras y el ajuste de la tarjeta de inserción.
• User manual review: Check labeling and instructions against the requirements applicable to each destination market and product configuration.

After sample and commercial terms are approved, issue a purchase order and confirm the production slot. Define specifications, quantity, price, delivery terms, inspection criteria, and payment schedule in writing.

• Emitir una orden de pedido formal: El pedido firmado debe especificar las cantidades exactas por referencia, el precio unitario, los Incoterms, el plazo de entrega, las especificaciones de embalaje y las condiciones de pago.
• Confirmación del calendario de producción: La fábrica proporciona un diagrama de Gantt o un programa de producción que muestra la fecha de inicio, la finalización estimada y los hitos de control de calidad.
• Component procurement: Confirm availability and lead times for specified PCBs, batteries, motors, and materials with the supplier; update the project schedule if an item is not ready.
• Packaging production kickoff: Coordinate artwork approval, production quantity, and delivery timing with the packaging supplier and assembly schedule.
• Inspection planning: Agree the inspection scope, provider, sample plan, and timing with the supplier and inspector; availability varies.

Document production checkpoints, test coverage, sample plans, limits, and failure handling against the approved specification.

• Inline quality checkpoints (document the agreed plan):
  • Housing: check dimensions and visible defects against the approved specification and sampling plan.
  • PCB: document test coverage and limits; describe a check as 100% only if each unit receives the stated test.
  • Assembly: verify alignment and seals against the specification. An air-pressure screen is not an IEC 60529 water-ingress test.
  • Final function: identify the functions tested per unit and how failures are recorded and handled.
  • Packaging: verify SKU, labels, accessories, and carton data against the approved specification.
• Solicite fotos/vídeos semanales de la producción: Unidades terminadas en la línea, registros de inspección de control de calidad y línea de envasado en funcionamiento
• Siga el progreso de la producción: For example, compare reported output with the production schedule and order quantity; investigate material variances early.
• If testing is required, confirm representative samples, scope, lab schedule, and production-change implications with the lab; timing is not guaranteed.

Pre-shipment inspection can check goods against the agreed purchase order and acceptance plan. Define scope and process in advance; it does not guarantee every shipped unit.

• Alcance de la inspección previa al envío:
  • Quantity: compare physical count with the PO and any tolerance expressly agreed in contract.
  • Sampling: specify procedure, inspection level, sample size, defect classes, and acceptance/rejection numbers. AQL is a plan parameter, not measured defect rate; MIL-STD-1916 uses verification levels, not an AQL table.
  • Workmanship: assess surface, color, assembly, and agreed criteria.
  • Function: identify test functions, sample plan, and pass criteria.
  • Packaging: verify carton markings, accessories, and barcodes against the approved specification.
  • Carton drop testing: use the agreed protocol for height, orientations, surface, repetitions, and acceptance criteria.
• Choose an independent provider, buyer-appointed representative, or supplier records based on the agreed scope and evidence requirements. Fees and availability vary; confirm in writing.
• Document the nonconformity, corrective action, rework, and re-inspection criteria. Added time depends on the issue and agreed disposition.
• Prepare documents according to route, product, battery configuration, destination, and buyer requirements. Use a certificate of origin or conformity document only when applicable.

The forwarder coordinates pickup and export formalities. Clearance timing depends on the shipment and its documents; confirm cutoffs and required records for the chosen service.

• Sea freight planning examples:
  • Shenzhen to Los Angeles: request a current route and service estimate.
  • Shenzhen to Hamburg or Rotterdam: request a current route and service estimate.
  • Shenzhen to Tokyo or Osaka: request a current route and service estimate.
  • Shenzhen to Sydney: request a current route and service estimate.
• Air freight may suit samples or urgent shipments. Transit and cost depend on route, service, chargeable weight, battery acceptance, and current capacity; compare current quotes.
• Classification depends on product configuration, jurisdiction, origin, and import date. Treat HS 8509.80 only as a possible heading to investigate, not a final national tariff code or duty.
• Shipment document checklist (confirm what applies):
  • Commercial invoice with accurate transaction value and required shipment information.
  • Packing list with package count, weights, dimensions, and contents as required.
  • Bill of Lading or Air Waybill for the selected service.
  • Certificate of origin only if required by destination, buyer, or applicable procedure; confirm correct form and origin rules.
  • Applicable conformity documentation for the product and destination.
  • FCC documentation only when applicable to the product and import.
  • Battery test summary and shipping information required for the battery design and shipment mode.

Prepare import paperwork before arrival. Confirm free time, storage or demurrage terms, and broker deadlines from current carrier and port information; charges vary.

• Share documents according to the broker’s agreed lead time. Pre-arrival review can identify gaps; no fixed number of days applies to every shipment.
• For applicable U.S. vessel shipments, determine whether ISF applies and submit required information within the regulatory timeframe before loading. ISF is not a general air-freight filing.
• For EU imports, confirm the economic operator and importer arrangements, applicable conformity documents, and customs registration requirements with the importer and broker. Keep these separate from the rules for Great Britain and Northern Ireland.
• Confirm the conformity route for Great Britain or Northern Ireland and the product. Great Britain recognizes CE alongside UKCA for many applicable products under current arrangements; Northern Ireland differs.
• Aranceles de importación a tener en cuenta:
  • US: duty and additional tariffs depend on final classification, origin, product details, and import date. Check current official sources and obtain broker advice.
  • EU: determine duty from the final classification, origin, and import date; do not rely on a generic percentage.
  • UK: determine duty from the final commodity code, origin, and import date.
• Prepare fulfillment requirements before dispatch. For Amazon FBA, confirm current carton, labeling, prep, and shipment-plan requirements in Seller Central; these differ from standard third-party logistics.

La carga pasa el control de aduanas y se entrega en su almacén o centro de distribución. El proyecto OEM está terminado. Pero el trabajo no ha terminado. La recepción es un punto de control de calidad que muchas marcas se saltan en detrimento suyo.

• Reconcile carton count and visible condition, then inspect units under the receiving plan agreed for the order. Any percentage sample is project-specific, not universal.
• Actualización del sistema de inventario: Registre los números de lote, las fechas de producción y los códigos de lote. Esto es importante para las reclamaciones de garantía y las posibles retiradas de productos.
• Amazon FBA receiving (if applicable): Reconcile delivered cartons and monitor receiving status against the shipment plan created before dispatch. Inventory availability depends on Amazon's processing.
• Fotografía y actualización de listados: Si aún no dispone de fotografías de productos, organice inmediatamente una sesión fotográfica en su empresa o en un estudio. Desea que los anuncios se publiquen a los pocos días de que el inventario esté disponible.
• Informe del proyecto: Documente lo que ha ido bien, lo que ha causado retrasos y lo que haría de otro modo. Esto se convierte en el procedimiento normalizado de fabricación para la siguiente producción.
