Quality & Compliance

Full-process quality control & global market compliance standards .

Strict testing, complete globalcertifications, stable batch consistency for allproducts

Quality Philosophy

Quality is embedded throughout every stage of our product lifecycle. Guided by rigorous quality‑oriented principles, we enforce unified quality standards for all our dishwashers, refrigerators and small home‑appliance products, whether standard stock models or customized OEM / ODM orders. We prioritize prevention at source and full‑process inspection, strictly complying with global safety standards to deliver consistent batch quality and complete traceable production records.

Full‑Lifecycle Quality Control

Quality runs through the whole product lifecycle, covering R&D design, raw‑material incoming check, in‑line production monitoring and final pre‑shipment audit.

Prevention‑Oriented Inspection

Prevention first, strict inspection as guarantee. We focus on risk avoidance in early‑stage processes rather than merely detecting defects after production.

Global‑Standard Compliance

Full compliance with global market safety standards. All products are developed and tested to satisfy EU and international safety & performance requirements.

Traceable Batch Production

Stable batch‑to‑batch quality & traceable production records. Every production batch retains complete inspection files for quality tracking.

Our Quality Control Steps

We are equipped with complete in‑house testing facilities for home appliances. Strict quality management aligned with ISO 9001‑aligned principles runs through the whole manufacturing workflow for dishwashers, refrigerators and small home appliances, covering both stock items and OEM / ODM orders. Our quality assurance workflow includes incoming material inspection, in‑process patrol check, finished‑product full test and pre‑shipment sampling audit. Complete inspection records are kept for every batch to achieve full traceability.

01 Incoming Material Inspection (IQC)

Before production starts, all raw materials and components go through strict incoming quality inspection. Unqualified components will be rejected to eliminate hidden quality risks from the source. All material inspection records are filed for traceability.

02 n‑Process Patrol Inspection (IPQC)

During mass production, regular on‑site patrol inspections are performed on assembly lines. We monitor assembly workmanship, working parameters and product conditions, to spot and correct process deviations in real‑time.

03 Finished‑Product Full Inspection (FQC)

Each completed unit undergoes comprehensive full‑item inspection, covering appearance, assembly status, functional performance, waterproof performance and safety‑related items. Only fully‑passed products can be admitted to finished‑goods warehouse.

04 Pre‑Shipment Sampling Audit (OQC)

Before delivery, finished goods are sampled and audited following AQL standards. We double‑check product condition, packaging, labels and supporting documents. Qualified batches are permitted for final packing and shipment.

Ongoing Type‑Test

Beyond production‑line inspection, we conduct comprehensive reliability verification for new models & prototypes. These ongoing lab tests simulate real‑world household usage and shipping conditions, helping us uncover potential design weaknesses and guarantee stable long‑term performance of home appliances.

Service‑Life Aging Test

Year‑round aging tests simulate long‑term real‑world use to verify durability for new and existing models. It delivers reliable long‑term performance and boosts your end‑user satisfaction.

Full‑range Performance Test

We periodically verify all core appliance indicators to meet design and EU standards. Every unit you receive maintains stable and promised functional performance.

Transport Simulation Test

Routine vibration and drop tests validate anti‑damage performance for cross‑border shipping. Your goods will arrive intact after long‑distance international transport.

Critical Components Evaluation

Key components are retested regularly to prevent quality drift in mass production. It guarantees consistent batch quality and lower failure rates for your sales.

With our in-house lab and annual R&D investment, we continuously innovate. Download the latest lab data here to verify our performance claims.

Certifications & Compliance

All our dishwashers undergo rigorous standardized testing by globally recognized TÜV Rheinland and SGS laboratories. The three documents below verify that our products meet unified EU safety, electromagnetic compatibility and energy efficiency standards, allowing legal sales throughout all EU regions. Full set of certified records streamline customs clearance, supplier audits and retail store registration for overseas partners, while delivering steady, interference-free and energy-saving daily usage experience to end users.

Note: These test documents are valid for EU markets only, and customized certification solutions for other regions can be provided upon demand.

SGS EMC Verification of Compliance

This official one-page compliance certificate from SGS confirms full compliance with EU EMC directives and satisfies market access requirements for all EU territories. It greatly simplifies compliance pre-checks when communicating with buyers and logistics providers, and strict electromagnetic control prevents signal disturbance to safeguard the normal operation of all household appliances for daily users.

TÜV Rheinland EMC Full Test Report (CN238TA3 003)

This complete EMC type-test report issued by TÜV Rheinland covers all dishwasher models and complies with EU harmonized EMC standards for sales across every EU country. It serves as core technical documentation for customs inspection and supplier qualification review during export, with certified anti-interference performance guaranteeing the machine will not disrupt televisions, routers and other household electronics while running.

TÜV Rheinland Energy Efficiency Test Report

This ErP energy performance test report is specially for model DW4-D30A, formulated in accordance with unified EU energy efficiency standards to support product sales in all EU member states. The file is compulsory for EU energy label registration and shelf entry of European online and offline retail channels, with verified low power and water consumption cutting daily household utility costs alongside reliable cleaning and drying performance for end consumers.

Built-In Quality, Verified Performance

Behind every appliance is our in-house laboratory, where we conduct rigorous pre-production testing and annual R&D validation. This ensures that when a new product leaves the drawing board, its performance metrics—from energy efficiency to structural durability—are already proven by hard data, not just projections.

Quality isn't just a checklist; it’s a closed-loop system. From IQC inspections to final OQC audits, we maintain full traceability across the production line. We invite you to download our latest Lab Test Data to see the transparency and reliability that define our manufacturing process.

FAQ
