The Step of Zinc-alloy

Mock up

Step 1 -- Mock Up

Confirm product details with customer and work out the mock up based on the technology.


1.Confirm the details with customer :
Material, Size, Plating Color, 2D or 3D, Craft or Technology, Thickness, and Attachment.

2.Customer shares design or clear pictures

3D CNC Artwork

Step 2 -- 3D CNC Artwork

Work out the 3D artwork according to the mock up


Customer should provide clear picture for the details.

Step 3 -- Mold Engraving

Set up the molding progress, put a blank mold on the engraving machine and engrave it out


1.It’s fit for a design is zinc alloy material, with big size, many internal cutting, excellent 3D effect.

2.Die-casting mold is rectangle shape and steel material, steel material is durable and with good corrosion resistance.

Mold checking

Step 4 -- Mold Checking

Check and clean the mold, second polishing for the mold to improve the die casting quality.

Opening Channel

Step 5 -- Opening Channel

Open the channel and fill space with the zinc alloy liquid on the mold


100% friendly material

Set up die casting Machine

Step 6 -- Set up Die Casting Machine

Place the molds correctly in the gravity-casting machine, fill the molten liquid zinc into the molds


Step 7 -- Embryo

When they cool off, the embryo is done.

Back pin riveting

Step 8 -- Back pin riveting

Rivet the clutch on the backside of the pin.


We have clutch in 8mm, 10mm, 12mm. 8mm clutch is common, and we use 12mm clutch if pins with LED light.

Polishing Surface

Step 9 -- Polishing Surface

Hand polish it again to a smooth mirror-like texture.


1.Polish lightly to advoid the damage if metal lines are very thin.

2.Avoid scratching.


Step 10 -- Plating

After polishing, we are going to electroplate. This process will creat a metal coating to improve the surface qualities of objects-such as the abrasion resistance, corrosion resistance,or appearance.


1.Before plating, it is necessary to confirm that the surface of the product is clean.

2.After plating, please check the quality.

Color Mixing

Step 11 -- Color Mixing

Mix color as pantone color number.


Only pantone solid coated we can do.

Enamel filling

Step 12 -- Enamel filling

Coloring every color by coloring needle, and to bake and dry the color when coloring done.


1.Only recessed area can be colored. The minumum coloring area of soft enamel is 3.0mm, and hard enamel is 0.5mm.

2. It is necessary a dividing line between two colors


Epoxy Covering

Step 13 -- Epoxy Covering

Adding epoxy dome a clear plastic coating to soft enamel, silkscreen, and off set print style metal products to protect your design from damage.


1.Used for the design with multi-color.

2.Used for a complicated design with some details can’t be colored.


Step 14 -- Printing

Pad Printing, an offset printing process that involves an image or logo being transferred via a silicone pad onto a substrate.


1. At present, the bigest logo our factory can print is 65mm.

2.Used for the design with multi-color.

3.Used for a complicated design with some details can’t be colored.
