How to customize own brand of hardware ?

• Stpe 1:Please send us the physical sample of the bag hardware you want to make or you can send the artwork to us for reference.please let me know the bulk quantity what color do you need ?
• Step 2:We will checking the physical sample(the logo size, the thickness, the weight ) or artwork after receiving and send quotation for you
• Step 3:After the quotation confirmed, we will send the proforma invoice for your confirmed
• Step 4:After proforma invoice confirmed, we will make the artwork for you and you can pay the payment
• Step 5:After the artwork confirmed. we will arrange the mould and sample for your approved
• Step 6:After sample approved, we will make the bulk production for you

What’s the process of making metal hardware and fittings for a handbag?

Regarding for manufacturing technologies of handbag metal accessories and hardware, it can be roughly divided into five stages: mold making process, die-casting process, polishing and grinding process, electroplating coloring technique and detail treatment technique. Accurate supportive operation is vital to guarantee the long term durability, look and compatibility of these accessories.

Mold Development: Precision Design Lays the Foundation

Requirement Analysis and Drawing Design

Choose hardware shapes (D-ring, horseshoe buckles, chains) based on handbag aesthetics (vintage,/modern/luxury-lite). Produce 3D design sketches with dimensions and specs labeled.

Mold Manufacturing and Trial Runs

Molds are carved using CNC machine tools to ensure cavity precision ≤0.05mm.After trial runs, sample dimensions and structural integrity are inspected. Adjustments are made until qualification is achieved before proceeding to mass production. mould development requires 7-15 days; complex fasteners may extend this to 20 days.

Die Casting: The Key to Liquid Metal Transformation

Material Selection and Melting

Zinc alloy (mid-range, excellent fluidity), stainless steel (high-end, corrosion-resistant), copper (vintage style, high malleability).Zinc alloy 680-720°C, stainless steel 1400-1500°C. we must strictly control the temperature to prevent impurities.

Die Casting Process

Molten metal is injected into the mold cavity and rapidly solidified under high pressure (150-200 MPa) Injection speed 0.5-1.2 m/s, holding pressure time 3-5 seconds, ensuring castings are free of porosity and shrinkage porosity Rough edges may exhibit flash or burrs on the blank, requiring subsequent processing.

Electroplating Coloring: Enhanced Texture and Durability

Selection of Electroplating Processes

• Rollering Plating: For small parts (such as eyelets, mushroom nails), it is cheap and less uniform overall.
• Hanging Plating: More controlled method suitable for large components (buckles, chains?as?Lplatin?) barrel plating to develop thicker thickness than BP (15μm, instead of 5μm)
• VACUUM : A high end choice that offers increased coating adhesion and at least 30% more wear resistance.

Plating Materials and Colors

Available Plating : 24K Real Gold(Luxury Grade), Platinum, Nickel(Bright Silver)age-Gold(Vintage Finish).

Environmental Protection and Durability

• Passes Rohs test (6p), lead and cadmium content is less than or equal to 0.1%, which reaches the EU standard..
• Salt Spray Test: neutral NSS≥96 hours does not appear white rust, ensure the hiding power will not change in water.

Optimization of Detail: The Balance between Functionality and Aesthetics

Structural Design

• Hidden Screws: Screw holes are positioned inside the bag to prevent exposed fasteners from compromising aesthetics.
• Weld Polishing: Laser weld points must be polished to a seamless finish, blending seamlessly with the main body.

Engraving and Marking

• Hand-Carved “Sand-Blasted” Technique: Creates crisp, precise brand logos with a depth of 0.1-0.2mm.
• Laser Engraving: Suitable for intricate patterns with precision ≤0.01mm.

Functional Testing

• Zippers: Withstand ≥5000 cycles of opening/closing without tooth breakage, smooth operation ≤3N resistance.
• Fasteners: Withstand ≥10000 cycles of buckle engagement/release without loosening, magnetic snap force ≥5N.
