How To Use Acrylic Solid Surface To Make Acrylic Sinks?

The acrylic artificial stone washbasin is manufactured through processes such as mold forming, resin pouring, curing and demolding, as well as polishing. The entire process combines the plasticity of polymer materials with industrial production technology, achieving one-piece molding and seamless splicing.

The production process is as follows:

Mold Preparation

Fabricate the modular resin mold according to the design drawings, ensuring precise alignment between the sink and countertop. The mold surface must be cleaned and coated with a release agent (such as a permanent release agent) to facilitate smooth demolding in subsequent steps.

Material preparation

Mix methyl methacrylate (MMA), aluminum hydroxide powder, curing agent, accelerator, and color paste to form a liquid acrylic artificial stone slurry. The color can be adjusted as needed to achieve various visual effects such as marble imitation and solid colors.

Casting and molding

Pour the mixed slurry into the mold, first cast the base layer and evacuate it to remove air bubbles, preventing cracks or voids in the finished product. Then proceed with secondary casting to ensure uniform thickness.

Heat and cure

After pouring is completed, the mold is placed into a constant temperature box for heating and curing, allowing the polymer material to fully polymerize and enhance its strength and stability. After curing, it is naturally cooled to room temperature.

Demolding and Trimming

Remove the outer mold, carefully extract the rough blank, use tools to trim burrs and excess parts, and reinforce the bottom with composite fiberglass to enhance structural strength.

Grinding and Polishing

Use 400-600 grit sandpaper for initial sanding, then progressively upgrade to 1000 grit or higher for fine sanding. Finally, apply polishing water and a scouring pad to achieve a mirror-like finish.

Punching and Quality Inspection

Drill holes for the faucet, drainage outlets, and other components according to standard positions, complete the final structural processing, and conduct quality inspections to ensure there are no cracks, pores, color differences, or other issues.
