2 configurations for PVC compounding and recycled plastic pellet production.

Define the input material, contamination, moisture, bulk density, required filtration and target pellet application. Recycled film may need compaction and strong degassing; rigid flakes may use force feeding; PVC compounding commonly uses hot-face cutting with controlled temperature. Washing is a separate upstream process unless it is explicitly included.

A complete proposal should identify what is included and excluded: main machine model, screw and barrel specification, drive and control components, tooling, downstream equipment, auxiliary systems, test conditions, documentation, packing and service. Ask the supplier to connect every quoted capacity to a stated material and product size. Final acceptance points should be written into the technical agreement before manufacturing starts.

For a useful configuration review, send the full product schedule instead of only the largest size. Include drawings or standards, material source, expected operating hours, local voltage, destination and workshop dimensions. This allows the engineering team to check changeovers, cooling capacity, utility demand and future expansion as one production system.
