We supply stainless steel frame, connectors , buckles , watch strap for watchs. And stably offering milanese stainless steel straps for Fitbit charge 2 , fitbit charge 3 , fitbit Versa , fitbit alta , alta hr watch bands replacement . Apple watch bands / iwatch bands replacement .
We manufacture metal strap & frames through metal injection molding (MIM) process in high-volume manufacturing . MIM is a excellent solution for small, intricate stainless steel components for a wide array of industries, including medical, aerospace, automotive, tools and wearables .
Metal injection molding (MIM) merges two established technologies, plastic injection molding and powdered metallurgy. This frees designers from the traditional constraints associated with trying to shape stainless steel, nickel iron, copper, titanium and other metals. Greater design freedom and more opportunity for innovation.
Metal injection molding process for watch accessories :
Step 1: Feedstock
-
Very fine metal powders are combined with thermoplastic and wax binders in a precise recipe. A proprietary compounding process creates a homogenous pelletized feedstock that can be injection molded just like plastic. This achieves ultra-high density and close tolerances over high-production runs.
- Unlike standard powder metallurgy, which can achieve only 80-90% of theoretical density, MIM results in 95-100%. This means we can achieve close tolerances and reduce costs by producing small, complex parts over high production runs.
Step 2: Molding
- The feedstock is heated and injected into a mold cavity under high pressure. This enables us to produce extremely complex shapes and allows for shorter cycle times.
- Once molded, the component is referred to as a "green" part. Its geometry is identical to the finished piece but is about 20% larger to allow for shrinkage during the final sintering phase.
Step 3: Debinding
- Binder removal (debinding) involves a controlled process to remove most of the binders and prepare the part for the final step - sintering.
- Once debinding is complete, the component is referred to as "brown."
Step 4: Sintering
- The brown part is held together by a small amount of the binder, and is very fragile.
- Sintering eliminates the remaining binder and gives the part its final geometry and strength.
- During sintering, the part is subjected to temperatures near the melting point of the material.
If you have any design just send us drawings and we will help to come true the design for you .
