A Quartz Countertop Fabrication Process

by Jayden Fisher

Quartz counters are an engineered product. Fabrication services involve the acquisition of the quartz, the blending of several materials, and the compressing of the materials. The steps below will outline how a set of custom counters that will be used to renovate your kitchen may be produced.

The Basic Production Steps

Quartz countertops are constructed of quartz, resin binders, and polymers. A pigmentation product is added to quartz countertops to provide each slab with a distinct color shade. A mining process is used to collect silicon dioxide.

Quartz is comprised of silicon dioxide and some impurities. A manufacturer may purchase quartz crystals from a supplier and keep the material at the counter fabrication facility. The crystals are poured into a large mixing bowl. Custom countertop fabrication strategies focus on the length, width, thickness, color, and texture of each slab.

A product that will be uniquely different from basic quartz counters may require that a distinct pigmentation and aggregate blend is added to the quartz, resin, and polymer blend. As raw materials are rapidly blended together, the material will take on a paste-like consistency.

The Mold And Heat Process

Compression and heat are used to form quartz slabs. A mold is used to contain the raw mixture that was produced during the initial blending steps. The mixture will be poured into an open mold. The pieces of the mold will be secured together. The mold may contain rounded edges. This will provide a quartz slab with its lipped edge. The top and bottom of a mold will be flat and uniform.

A compression machine places the mixture under immense pressure. A vacuum function that a machine possesses will eliminate air pockets from the mixture. Ideally, each concrete slab will be an inch or two in thickness.

The Baking And Finishing Steps

After a slab is removed from the mold, it is moved into a heating vessel. The heating process is similar to baking a product in an oven. The heat will eventually harden a quartz slab. It will also eliminate bacteria and remove any small gaps that weren't removed during the baking process.

After the heating vessel is turned off, a slab will need to cool down. Finishing steps are conducted next. These steps may include sanding and polishing a slab. Upon the completion of these steps, a quartz slab may be packaged and shipped to a warehouse or another facility where custom products have been ordered from.
