What is rebirth of quartz?

Renewing quartz is recycling and reproducing new quartz glass products from discarded ones

Recycling is a key nowadays in many different businesses due to the global environmental issues.

Our partner company’s technology go further more than just recycling, it produces better quality items. It is Koshin’s original Perfect Renewing Technology.


What is Perfect Renewing Technology?

The original melting method can remove much foreign matters.
* Upgraded the flame process machines makes remaking melting more than 100 Celsius higher than previous machine. This brings to remove foreign matters much more. As it repeats the renewing process more stain are removed. Thus this Perfect Renewing Technology successfully produces high purified quartz more than new ones.

Polishing technology makes no stain build up
For those parts which are being etched and considered as waste, we completely grind the reflecting sides’. This brings NEW LAYER with no foreign substance.

Combination of these two technologies is Perfect Renewing Technology which makes better quality, better than new products.
