The processing process of quartz stone countertops is a complex and precise process, usually including the following steps:
Material procurement:
The first step in the processing process is to purchase suitable quartz raw materials. These raw materials include quartz crystals, pigments, resins, hardeners, and other additives. The quality of raw materials is crucial for the quality of quartz stone worktops.
Raw material mixing:
Raw materials such as quartz crystals, pigments, and resins are mixed together in specific proportions. This mixing process ensures that the color and texture of the quartz countertop are evenly distributed, and ensures that the material has the required strength and durability.
Mold making:
Manufacturers usually make customized molds based on the required quartz worktop size and shape. These molds will be used for casting or pressing quartz flakes.
Casting and hardening:
In the mold, the raw material of quartz stone is cast or pressed into the shape of a plate. Casting is the process of pouring mixed materials into a mold and then curing at high temperatures. Pressing is the process of pressing raw materials into thin sheets under high temperature and pressure.
The finished sheet needs to be hardened at a constant temperature for a period of time to ensure that it reaches the required hardness and stability. This is usually done in a dedicated hardening furnace.
Cutting and trimming:
The hardened sheet is cut into the required size and shape. This typically includes cutting openings such as sink holes, stove holes, and faucet holes to meet specific countertop designs.
Polishing and edge treatment:
After cutting and trimming, polish and polish the quartz plate to obtain a smooth, uniform, and bright surface. This process is usually completed using sandpaper and grinding heads of different thicknesses.
The edges of the quartz countertop require special treatment to enhance its aesthetics and safety. Common edge processing methods include chamfering, rounded corners, right angles, etc.
Quality inspection:
The manufacturer will conduct strict quality inspection on the quartz stone countertop to ensure that it meets the standards and regulations. This includes checking dimensions, flatness, color consistency, and any defects.
Packaging and transportation:
The completed countertop is packaged to prevent damage and prepared for transportation to the seller or end user's location.
Each step requires a high level of technical and professional knowledge to ensure that the final quartz stone worktop has the required appearance, performance, and durability.
