Production

              Shell Frames

We make handmade shell frames with cellulose acetate (C76H114O49) which is purified natural cellulose, and is a hypoallergenic material  and virgin sheets with new granules. All our frames are hypo allergic and suitable for men, women and kids of all ages

The chain process in shell units involves manual milling, CNC milling, scraping, barrelling, assembling, packing and quality checking. The acetate sheet is made from. The three layers of cellulose acetate are single layer,multi-layer, DA (Demi Ample) or Havana. It contains 80% organic material. Our regular sheet has a hardness of 90, and our high density sheet has a hardness of 105.

  • Dimensional tolerance:+0.5mm

             Metal Frames

Our metal frames use 18% German silver, along withMonel and stainless steel materials andfive layer plating for lasting colour.These can be customized according to various customer requirements, such as colour and size.

The chain process of metal frame productionis as follows:soldering, buffing, plating, assembly, packing.Metal frame is a general term used to refer to frames made from metals such as copper alloys. Improvements in surface finishing have produced a wide range of coloring.The types of metal frames we produce include:titanium, b-titanium, beryllium, stainless steel, monel and nickel silver. The metal frame has a 5layer coating for durability.

QC Test:

  • Bridge Deformation test.
  • Endurance test for joints.
  • Perspiration test.
  • Nickel release test.

Properties of Cellulose Acetate

Cellulose acetate is one of the most important esters of cellulose. A special field for using cellulose acetate is the synthesis of porous, spherical particles, so called cellulose beads.
