Why are the Prices of Granite Composite Sinks?
2021-01-21 14:24:20Factors that cause the price difference of granite composite sinks from different sink maufacturers are complicated.
Let's take Xiamen Boma International Trade Co., Ltd.(Boma International) as an example. Boma International was established in 2005 and is an international enterprise integrating R&D, design, production, sales and supply chain integration of kitchen and bath ceramic sinks.
Let us first understand the composition of a granite composite sink produced by the company and the molds needed to produce a granite composite sink.
1. Composition of granite composite sink
Quartz sand (QUARTZ) + resin (ACRYLIC RESIN) + trace catalyst (ACCESSORY INGREDIENT)
Quartz sand is a small particle after calcination of granite. Quartz sand is divided into domestic and imported quartz sand. Approximately: 80%.
The resin is divided into acrylic resin (acrylic resin PMMA) and unsaturated polyester resin. Approximately: 20%.
Steel mold: The granite composite sink produced with steel molds is of high quality and has a long service life.
Resin mold: The granite composite sink produced with a resin mold is of relatively poor quality and has many defects, such as it's easy to produce bubbles, leading to a shorter service life.
For granite composite sinks with the same production process, the reason for the different prices lies in the different raw materials and quality:
1. Imported quartz sand + pure acrylic resin + steel mold production, the quality of the granite composite sink is mid- to high-end, and the corresponding price is also high.
2. The quality of domestic quartz sand + unsaturated polyester resin + resin film production, granite composite sink is low-end, and the corresponding price is low.
