A kind of facing shaping machine structure comprising: body, forming part, clamping part and heating part. The forming part system is arranged on the what body, has opposite male and female structure between a tooth mould, so that the tooth mould can be placed on the fixation position of the what forming part. The heating part system is movably disposed on the what body, to heat to the diaphragm clamped by the clamping part. When the what tooth mould is placed in the what forming part, which can be moved on the forming part and engaging with the forming part makes on membrane covered what tooth film clamped by the clamping part. Thereby, it can definitely fix the position of tooth mould, diaphragm is effectively thermoformed into facing. In addition, more can be by configuring the clamping part to make facing using the smaller non-circular diaphragm of area, to reduce the waste of resource.一種牙套成型機結構，其包括：機體、成型部、夾持部、及加熱部。該成型部係設置於該機體上，其與一齒模之間具有相對之公母結構，從而讓該齒模能夠被置放於該成型部之固定位置上。該加熱部係可移動地設置於該機體上，用以對該夾持部所夾持之該膜片進行加熱。於該齒模被置放於該成型部上時，該夾持部可被移動至該成型部之上而與該成型部接合使該夾持部所夾持之該膜片覆蓋於該齒膜上。藉此，可確切地固定齒模之位置、有效地將膜片熱成型為牙套。此外，更可藉由配置該夾持部以利用面積較小之非圓形膜片來製作牙套，從而減少資源的浪費。
