What Is Acrylic?

Acrylic bathtub sheeting is a highly popular type of plastic. Lightweight, affordable, and resistant to shattering, it serves as an ideal material for a wide variety of bathroom products. LiangJian is simply one brand name for high-quality acrylic sanitary ware sheeting. It is a distinctive material found everywhere in daily life—from large-scale billboard designs down to tiny adhesive stickers.

How are acrylic bathtub sheets cut in an industrial setting?

In the production of bathtubs—where acrylic serves as the primary exterior material—the « cutting » of acrylic sheets is not a singular process; rather, it is a procedure that spans multiple stages, ranging from pre-forming and forming to post-forming finishing. Consequently, the equipment and methods employed vary depending on the specific stage of production.

I. Pre-forming Cutting (Blanking)
Prior to undergoing thermoforming, acrylic sheets undergo an initial cutting process:
Common Equipment:
Precision Panel Saw
CNC Cutting Machine
Function:
To cut the sheets according to the dimensions required by the mold or the specifications requested by the client.
To optimize material utilization and enhance product quality.
To minimize waste, thereby contributing to environmental sustainability.

II. Post-Thermoforming Cutting (Core Step)
This constitutes the most critical stage of the cutting process.
After being heated, the acrylic sheet is vacuum-formed into the shape of a bathtub; however, at this stage:
The edges are irregular;
There is a significant amount of excess material;
The dimensions lack precision.
Therefore, a secondary cutting process—known as « trimming »—is absolutely essential.
Common Methods:
CNC Trimming (The Most Prevalent Method)
Utilizes 5-axis or 3-axis CNC machinery;
Precisely cuts the edges according to a CAD model.
