In a method of integrating an active pharmaceutical ingredient (API) with a thermoplastic polymer, the thermoplastic polymer and API are into a first feed port of a multi-screw extruder or the thermoplastic polymer is fed into the first feed port of a multi-screw extruder, the thermoplastic polymer is conveyed along the heated multi-screw extruder while heating the thermoplastic polymer to a melt temperature of 160° C.-280° C. prior to the thermoplastic polymer being conveyed past a second feed port and the API is fed into the second feeding port in the heated screw extruder to mix with the melted thermoplastic polymer to generate a compounded mixture containing 85-100% of the starting API content. The compounded mixture is extruded from an outlet of the heated screw extruder and cooled via a cooling device such that the compounded mixture contains 85-100% of the starting API content.

A performance of a die is improved. An injection hole IH, a nozzle NZa and a nozzle NZb are formed in a center member DIa of a die DI to extend from an extrusion surface ES to an injection surface IS. A heat source HT and a plurality of heat insulating layers HI1 are arranged inside the center member DIa. One of the plurality of heat insulating layers HI1 is adjacent to the nozzle Nzb and is closer to the extrusion surface ES than the heat source HT. The other of the plurality of heat insulating layers HI1 extends in a direction from the extrusion surface ES toward the injection surface IS at a position being farther from the nozzle NZb than the heat source HT.
