The R-4 Reciprocating Screw Blow Molding Machine is best characterized by it's versatility, with easy mold and tooling setup, quick color changes, and height adjustments with T-square arrangements. The R-4's rapid parison drop rate is advantageous for thin-walled containers, typically used for dairy and juice bottle production. Wide mouth containers can also be made using Rocheleau's automated secondary spin trim system, at a much lower cost than comparable continuous extrusion machines.

Solid state PLC electronics provide dependable, user-friendly access to machine controls, with file storage for multiple job setups. Controls can be easily modified to allow for special functions such as needle blow, dual pressure blow controls, bottom blow, core pull mold action, etc. for smaller medical parts, industrial, and toy applications.
