Technical term for plastic food container molds
Coil material is a rolled material that can be used for multiple stamping. Sheet material is a sheet material that can be used for multiple stamping. Strip bar material is a strip material that can be used for multiple stamping. The drawing mark is the friction mark between the material surface and the working surface of the plastic food container mould during the forming process of the punching piece. The ratio of drawing depth to drawing depth is the inverse of drawing depth coefficient. See "depth factor". The drawing coefficient is the ratio of the diameter of the cylindrical drawing part in this process to the diameter of the drawing part in the previous process. For the first drawing, the drawing coefficient is the ratio of the diameter of the drawing part to the expanding diameter. The turbinate ear is an ear shaped projection on the edge of the upper mouth of a deep drawing piece. Feeding is to feed raw materials into the plastic food container mould for stamping. The feeding device is the device that sends raw materials into the mould of plastic food container. Common feeding devices are roller type, clamping type, hook type, etc. See related terms.
Hopper hopper is a bucket container with an automatic directional delivery mechanism for forming punch. The bending radius is the inner radius at the bend of the punch. The expansion diagram is the graphic of the planar working parts corresponding to the forming stamping parts. The expansion size is the dimension of plane working parts corresponding to the size of forming stamping parts. Arch - lifting is the name for the phenomenon of arched irregularity on the surface of punch. Wrinkling and wrinkling is the name of the phenomenon of corrugated pleats on the flange of deep drawing parts. The material trough material groove is a kind of channel that makes the punching part enter or leave the plastic food container mould in sequence. Hook feeding device hook feeding device is a device that USES the reciprocating hook to extend into the hole and drive the raw material into the punch.
