Pattern mold
Landscape design, deep cavity floating body, intricate and curved shapes, complex injection mold structure, high cost of mold opening, and difficult demolding; Sheet metal splicing makes the weld seam more prone to deformation; The wall thickness of hand pasted fiberglass is uneven and the strength is unstable. Roll molding has good shape following properties, no dead corners in rotary molding, deep cavity irregular integrated molding, uniform wall thickness, smooth surface, and can embed reinforcement ribs. The cost of aluminum molds is much lower than that of injection molding complex molds, and small batch customization is flexible.
