Artificial stones and Rong Jih crafts

The exclusively produced red dragon dinner tables and tea tables have been distributed to as many as 800 stores throughout Taiwan. Sinshe Township¡¦s artificial stone industry has taken shape. The original furniture arriving in new patterns and colors has taken more market share than DuPont stones, Rome Granite, and natural stones. Rong Jih has a great reputation for efficiency and on-time delivery in the industry and will continue to provide dedicated services.
 
Light-penetrating alabaster

With our dedication to delicate workmanship, we provide customized services catering to your needs. We use distinctive patterns of Spanish alabaster which has withstood rigid testing and proved to be non-toxic, and free of formaldehyde and lead. By simulating the natural stone series, our wash-basins are both strengthened and embellished.
 
Craftsmen of the Mountains

Amidst the beautiful mountains of Sinshe Township, Taichung, a group of industrious farmers toiled for over a century and became the "Craftsmen of the Mountains¡¨ who strived for perfection. Thirty years of workmanship in artificial stone demonstrated the virtuosity of the Taiwanese people, seizing the opportunities from the blue ocean.
  Overview of artificial stones
According to Dr. Yuan-Chih Wang, a German materials Ph.D, there are two paths for the application of compound artificial stone materials.
1. Superior technology, e.g. specific characteristics that are byproducts of nanotechnology
2. Extraordinary degree of difficulty and sophisticated craft techniques which cannot be imitated by others.
The U.S.: First introduced forty years ago, wash stands and basins using artificial stones have become common products. In addition, artificial stones are also applied to other products, such as bathtubs and toilets.
Japan: TOTO¡¦s artificial stone plant, with about 600 employees, mainly uses the gel-coat system, and their technical personnel have visited Rong Jih several times.
Korea: The General Manager of Daewoo¡¦s artificial stone plant (about 150 employees in size) visited Rong Jih once.
China: The gel-coat-free system is the mainstream in China.
Taiwan: The major product is wash basins. Rong Jih uses its original patented products as the core force of its production.
  What are the differences between DuPont stones and artificial stones?
DuPont Stones: They are ¡¥cuttable¡¦ artificial stones without gel-coat.
Artificial stones: They are the mold shaped or gel-coated artificial stones.
Differences:
1. DuPont Stones are mostly processed into slabs for sale. The slabs are then carpentered into finished products. Mass production is difficult, and they are also costly to process. On top of that, the patterns are very limited in number.
2. Artificial stones can be applied in mass produced products and mold-shaped into finished products. The products made of artificial stones have high authenticity of stone patterns and their craftsmanship is also quite sophisticated.
3. There is no significant difference in terms of durability. However, DuPont stones have higher thermal shaping characteristic on slate bending, while artificial stones are apparently better than DuPont Stones in terms of their pollution-resistant gel-coat.

Brief description of the production process
DuPont Stones: Stirring and vacuuming ¡÷ Slab shaping ¡÷ Finished product processing
Artificial stones: Gel-coating ¡÷ heating ¡÷ Stirring, and manually creating patterns¡÷ mold shaping

For example: Rather than use DuPont stone series, Japan¡¦s TOTO has been using a penetrating gel-coat system even for kitchen counters. This illustrates that products produced by Rong Jih with the penetrating gel-coat system can excel those produced with the gel-coat-free system.



 


  Materials

Secondary materials: Expensive additives, UV absorbent and aging resistant.


How to examine a Silver Fox tops

Grade AA: Tailor-made Silver Fox, products of Rong Jih
Grade A: Local 1st grade manufacturer Tx Tx and x¡K
Grace C: Colored gel-coat tops


Quality introduction to customers
1. When touching and sliding your hand across the surface (or inner rim), it should feel smooth (grade C products may hurt hands).
2. No flaws, scratches and dents are found on the bright surface by visual inspection. Also, no trace of repair is left.
3. Only the products having drawing and QC instruction enclosed are of good quality.




Rong Jih¡¦s AA grade MRT Muzha line furnishing is still as new as it was ten years ago.

  Advantages of using artificial stones for tops
1. Good pollution resistance.
The liquid penetration rate of artificial stones is almost zero, which makes them excellent materials to prevent penetration of polluted water and to keep the original color intact.
2. Wear-resistance:
For artificial stones, the Mohs scale of mineral hardness is between 1.0 and 2.0 and Rockwell hardness is 89.3 (ASTM-D785 test). The data illustrates their good durability for tops with artificial stones.
3. Maintenance method:
Clean directly with a wet cloth. For long-term accumulated dirt and grime left on the surface, lightly wiped off with a scouring pad (the ones exclusive for dish washing) with some dish cleanser.
4. The products can be used for more than 15 years, and even 22 years if used outdoors.

  To be used at construction sites and on the wall
1. The corner shelves sustain the salty spray test for 36 hours. They are coated by the same quality powder coating products exported to the U.S.
2. Material used for the products: Weather-resistant resin and refined stone powder with exquisite quality, and differing from what we commonly see in the market.
3. All materials are added with nano-grade formula, to boost the product¡¦s pollution resistance and explosion-prevention capacity by 50%.
