Abstract
The invention relates to an injection-molding process for producing a plastic molded part in a cavity of a tool. The process includes simultaneously injecting different melt streams composed of different component materials into the cavity, and controlling the injecting operation to obtain a form-fitting and/or material-bonding connection between the different component materials. The process further includes acquiring measurement data concerning the two melt streams at the site of development of the form-fitting and/or material-bonding connection and adapting the control to optimize the injecting operation on the basis of the measurements data acquired.
Claims20
An injection-molding process for producing a plastic molded part in a cavity of a tool, the process comprising:
- simultaneously injecting different melt streams composed of different component materials into the cavity;
- controlling the injecting operation to obtain a form-fitting and/or material-bonding connection between the different component materials;
- acquiring measurement data concerning the different melt streams at a site of development of the form-fitting and/or material-bonding connection;
- and
- adapting the control to optimize the injecting operation in response to acquiring the measurements data.
A computer readable medium embodying instructions that, when executed by a processor, cause the processor to perform a process comprising:
- simultaneously injecting different melt streams composed of different component materials into the cavity;
- controlling the injecting operation to obtain a form-fitting and/or material-bonding connection between the different component materials;
- acquiring measurement data concerning the different melt streams at a site of development of the form-fitting and/or material-bonding connection;
- and
- adapting the control to optimize the injecting operation in response to acquiring the measurements data.
A device for carrying out an injection-molding process, the device comprising:
- a cavity for producing a plastic molded part;
- two separate melt flow-way systems for the cavity;
- two separate injecting units, each of the two separate melt flow-way systems being assigned one of the injecting units, the two separate injecting units being designed to inject two different melt streams composed of different component materials into the cavity simultaneously by way of the two separate melt flow-way systems,
- a control device, the control device being designed for controlling the injecting operation to obtain a form-fitting and/or material-bonding connection between the component materials,
- sensors for acquiring measurement data concerning the two melt streams at least at a site of development of the form-fitting and/or material-bonding connection, the control device also being designed for adapting the control to optimize the injecting operation on the basis of the measurement data acquired.
