Description

Technical Field

[0001] The invention relates to the technical field of cold and hot pressing, and in particular to a cold and hot pressing machine. Background Art

[0002] At present, the production process of cold and hot pressing production equipment is to complete a production process over and over again. The above production method has disadvantages. When placing raw materials and accessories, the operator's hands must be exposed in the compression space of the machine, and if there is a heated mold, the temperature may be as high as 180°C or higher.
