CLAIMS:

1. An extruder comprising:

(a) an axially extending extruder barrel module having a feedstock inlet end and a feedstock outlet end axially spaced from the feedstock inlet end in a direction of flow through the extruder barrel module, the extruder barrel module comprising an axially extending barrel in which an extruder barrel screw is removably receivable;

(b) an axially extending extruder feeder module removably connectable to the feedstock inlet end of the extruder barrel module, the extruder feeder module having an axially extending flow passage aligned with the direction of flow when the extruder feeder module is connected to the barrel module, the axially extending flow passage having a feedstock outlet end and a screw motor module mounting end axially spaced from the feedstock outlet end of the extruder feeder module in a direction of flow through the axially extending flow passage;

(c) a screw motor module removably connectable to the screw motor module mounting end of the extruder feeder module, the screw motor module having a motor drivingly connectable with a screw in the flow passage of the extruder feeder module; and,

(d) an electronics module electrically connectable with the screw motor module and mechanically removably mounted as part of the extruder.

2. The molding apparatus of claim 1 wherein each module is shippable by a commercial courier company.

3. The molding apparatus of claim 1 wherein each module weighs under 175 lbs, 150 lbs, 135 lbs, or 100 lbs.

4. The molding apparatus of claim 1 wherein the screw in the flow passage is drivingly connectable with the extruder barrel screw when the extruder is assembled.

5. The molding apparatus of claim 1 wherein the screw in the flow passage and the extruder barrel screw comprise a single integrally formed screw.

6. The molding apparatus of claim 1 wherein the screw in the flow passage and the extruder barrel screw are removable as a unitary member from the extruder barrel module and the extruder feeder module.

7. The molding apparatus of claim 1 wherein the electronics module is also electrically connectable with the extruder barrel module.

8. The molding apparatus of claim 4 wherein the electronics module is also electrically connectable with the extruder feeder module.

9. The molding apparatus of claim 1 wherein the electronics module is also electrically connectable with the extruder feeder module.

10. The molding apparatus of claim 1 wherein the electronics module is automatically electrically connectable with the screw motor module when the electronics module is mounted as part of the extruder.

1 1. An extruder comprising:

(a) an axially extending extruder barrel module having a feedstock inlet end and a feedstock outlet end axially spaced from the feedstock inlet end in a direction of flow through the extruder barrel module, the extruder barrel module comprising an axially extending barrel in which an extruder barrel screw is removably receivable;

(b) an axially extending extruder feeder module removably connectable in flow communication with the feedstock inlet end of the extruder barrel module, the extruder feeder module having an axially extending flow passage aligned with the direction of flow when the extruder feeder module is connected in flow communication with the barrel module, the axially extending flow passage having a feedstock outlet end and a screw motor module end axially spaced from the feedstock outlet end of the extruder

feeder module in a direction of flow through the axially extending flow passage;

(c) a screw motor module removably drivingly connectable to an end of a screw located at the screw motor module end of the extruder feeder module; and,

(d) an electronics module electrically connectable with the screw motor module and mechanically removably mounted as part of the extruder.

12. The molding apparatus of claim 1 1 wherein each module weighs under 175 lbs, 150 lbs, 135 lbs, or 100 lbs.

13. The molding apparatus of claim 1 1 wherein the screw in the flow passage is driving connectable with the extruder barrel screw when the extruder is assembled.

14. The molding apparatus of claim 1 1 wherein the screw in the flow passage and the extruder barrel screw comprise a single integrally formed screw.

15. The molding apparatus of claim 1 1 wherein the screw in the flow passage and the extruder barrel screw are removable as a unitary member from the extruder barrel module and the extruder feeder module.

16. The molding apparatus of claim 1 1 wherein the electronics module is also electrically connectable with the extruder barrel module.

17. The molding apparatus of claim 15 wherein the electronics module is also electrically connectable with the extruder feeder module.

18. The molding apparatus of claim 1 1 wherein the electronics module electrically is also electrically connectable with the extruder feeder module.
