This series of models is double-sided compacted. The difference between the double-sided compaction shape and the ordinary shape is only the difference in the mutual movement between the molding sand and the template. Its styling process and process is to place the pre-filled frame between the sand box and the formwork. Adopting the template-type compaction process and the multi-contact compaction mechanism, the template can be moved freely up and down, and the molding sand in the pre-filled frame is pushed and pushed from the sand-type (sand box) parting surface, and the compactness is adopted. It is a parting surface and a high back, while the lower ideal ideal curve distribution achieves a perfect combination of high compaction and good breathability.
