What We Can't Do
We'd rather be upfront than waste your time.
No precious metals. We do not work with pure gold, platinum, or fine silver.
No fine jewelry with gemstone setting. We are a fashion jewelry and accessories factory.
No projects without a reference. We need a drawing, photo, sample, or clear description. We don’t design from a blank page for free.
No orders below MOQ. We are a bulk manufacturer, not a sample shop.
No counterfeit or trademarked designs. We will not reproduce brand logos or protected designs.
No medical or implant-grade products. Our titane line is for fashion body jewelry, not surgical implants.
No rush orders under 5 days. Our quality testing alone takes 2–3 days.
No certifications we don’t hold. We comply with REACH and CA Prop 65. We do not claim other certifications.
If your project falls outside these lines, we'll tell you honestly and, where possible, point you elsewhere.

- Signer un accord de confidentialité (NDA) afin de protéger les deux parties
02｜Étude de conception et revue technique
Collecte des besoins: soumission des concepts initiaux, des fichiers de logo et des spécifications du matériau (acier inoxydable 316L). Nous acceptons les deux types de fichiers de conception suivants : Fichiers de conception 2D (AI, PDF, CDR, PSD) ainsi que modèles 3D (STP, STEP, IGS, STL).
03｜Devis et paiement de l’acompte
Devis détaillé: nous vous fournirons un devis détaillé sous 24 heures, comprenant le prix EXW (départ usine), les frais de moule éventuels, les frais d’échantillonnage et les frais d’expédition.
Paiement de l’acompte : Veuillez consulter la facture proforma (PI) et versez l’acompte. Nous commencerons le projet dès réception du paiement.
04｜Conception 3D et validation
Transformez vos croquis ou images de référence en modèles CAO/3D.
Confirmez chaque détail : avant la fabrication de l’échantillon, vous pouvez vérifier une dernière fois les dimensions exactes, l’épaisseur et le positionnement du logo.
Délai : 2 à 5 jours ouvrables
05｜Validation de l’échantillon
Avant la production en série, un échantillon physique est produit pour approbation.
Nous sélectionnons le procédé le plus adapté en fonction de votre conception et de votre structure.
- Les méthodes de façonnage comprennent : la fonte à cire perdue, le MIM, la gravure CNC et l’estampage ou l’impression 3D.
- Procédés spéciaux :sertissage, application d’émail ou d’huile.
- Options de finition : polissage miroir, texture brossée, placage PVD (or, or rose, noir).
06｜Production en série et contrôle qualité
La production en série respecte les échantillons approuvés et fait l’objet d’un contrôle qualité à chaque étape :
Contrôle des matières premières à réception.
Mise en forme et moulage: contrôle des dimensions et de l’intégrité structurelle.
Polissage: contrôle de l’état de surface et recherche de défauts.
Assemblage: contrôle du sertissage et des procédés spéciaux.
Placage : contrôle de l’épaisseur, de l’adhérence et de l’uniformité de la couleur.
