In traditional and contemporary lacquerware production, achieving structural integrity in delicate, hollow-form pieces is a significant challenge. The molding process requires a reliable internal filler to support the shape without adding weight or affecting the geometry. Conventional fillers often bond with the lacquer, are too heavy, or fail to provide even support, leading to rework and compromised quality.
Our bubble film manufacturing machines offer a tailored solution for this issue. Designed for precision and consistency, machines like the 2-Layer Low-Speed and 7-Layer High-Speed Bubble Film Machines produce a specialized grade of polyethylene bubble sheet. This controlled, uniform bubble matrix acts as a temporary filler during the lacquerware molding and curing process.
The engineered bubble film provides essential internal support, bearing the pressure of applied materials and preserving the shape of complex pieces like vases and bowls. Unlike traditional fillers, our bubble film is non-adhesive and flexible, making it easy to remove post-curing through a small opening. This results in a lightweight, hollow structure without damaging the lacquer shell, eliminating the need for destructive removal methods.
With our bubble film manufacturing technology, lacquerware producers benefit from consistent quality, faster production times, and higher yield. The 2-Layer Medium-Speed machines are ideal for smaller production runs, offering precision and flexibility. For larger-scale manufacturing, the 3-5 Layer High-Speed systems deliver high output and layer control.
Each machine in our range is engineered with decades of experience, ensuring the bubble film produced meets the exact tensile strength, uniformity, and release properties required for this specialized application.
