AI Technical Summary

Technical Problem

When using existing fiberglass molds to produce acrylic artificial stone, the complex outer shell and inner cavity are difficult to remove, resulting in a large number of molds, complicated steps, and high product weight and cost. The split-type process affects the integrity and strength of the product.

Method used

The mold structure combines a lightweight mold core with supporting components. The lightweight mold core forms a cavity with the upper and lower molds, which is retained inside the product after casting, reducing demolding steps and slurry consumption. Polyurethane foam mold cores are used as lightweight mold cores to reduce weight and cost.

Benefits of technology

It enables the low-cost production of lightweight and structurally strong artificial stone products, simplifies the process steps, reduces material consumption, and maintains the integrity and strength of the product.
