  • Brass Mold HA02,HA03: Too heavy to be produced, we keep trying for the hollow inside to reduce weight possibilities.

1st Brass Mold all failed at the end of June

  • HA03 size is far large than the normal earring size
  • HA02 caused leaking when plating on the circle
  •  HA01 we divided into 2 pcs, it failed when combined together

Solutions & Results

  • SS Mold Try for HA02, HA03: Secussed try with SS material
  • HA01 Resin: Secussed Try with a Resin material for HA01.
  • HA02, HA03 Resin Samples: To comply with HA01, try resin material for another 2 styles. Success Try for this material.
  • Plating for Resin: The procedure for Resin and stainless, brass is quite different, fixture test another 2 times.
  • Final Result: HA01 production with resin only; HA02, and HA03 can produce with stainless steel and resin material.

The second trial of brass material samples failed

  • 1. HA03 size is corrected size (to make them lighter, we made them inside hollow, but caused leaking after plating). Failed again.
  • 2. HA02 We weld the whole surface again but still leaking inside; Reason: Brass material electric plating is easy to leaking when plating.

HA01 resin samples with no plating

  • HA01 is very suitable for resin material because of its complicated structure. here are the resin samples
  • HA01 resin samples (Yellow Color and Gold Plating Samples)—-we made yellow resin earring and plating samples in case plating will be not scuccess
  • Second Samples for HA02 Stainless steel  Material
  • HA02 stainless samples with 18K plating
