EMBOSSING & STAMPING,
HEAT SEALING & MOLDING
BRUNO Mold and Trim Presses are controlled by four interactive variables…load, position, velocity and time. You cannot pre-set all system variables; e.g. if load is controlled, position will vary with time and the compressibility of the material. If velocity and final position are set, load will vary right.
The tooling for molding presses may be heated and can contain auxiliary hydraulic cylinders to cut surfaces that are not perpendicular to the platen motion. Close control of the full closed position of the tool is normally accomplished with stop blocks in the tool.
The selection of a mold and trim press requires a thorough understanding of the intended process or the recognition that the press is a process development tool and must have all the anticipated control functions to develop a process.
The following is a list of parameters that are often a part of a mold and trim press cycle:
