R&B Plastics to introduce new all-electric extrusion blow shuttle model at NPE
R&B Plastics, a manufacturer of all-electric extrusion blow molding (EBM) shuttle machines, hydraulic accumulator machines, and single-screw extrusion systems, will launch its newest RBS-E550D All-Electric shuttle unit as well as display the MAX Series Single-Screw Extruders at NPE 2024.
RBS Shuttle Machine Series from R&B Plastics.
Latest all-electric EBM shuttle unit
RBS-E550D All-Electric EBM Shuttle machine will be configured with a W. Müller 2 x 250mm CD tri-layer die-head with individual servo electric wall thickness controls. Housed between the main extruder and die-head is W. Müller’s new melt filtration technology, the WM-096 Manual Screen Changer System.
At NPE, the new all-electric shuttle machine will be outfitted with a main extruder size of 100mm x 26:1 L/D ratio and designed for processing regrind PE-type resins. The satellite extruders, for inner and outer layers, are sized at 70mm x 24:1 L/D ratio.
The machine features a heavy-walled steel tube and steel plate frame construction with “walk-in” molding area and “top of machine” access platforms for long life and easy maintenance.
Equipped with Yaskawa X absolute servo motors and drives, the machine offers fast and smooth machine motions. W. Müller’s Model WM-096 manual screen changer is easily accessed for screen pack changes or system maintenance.
It also offers in-machine deflashing with “center of machine” scrap removal which keeps the conveyor behind the clamping/molding stations and allows for a more open area when performing mold changes or machinery maintenance.
The in-machine servo electric part takeout system includes a “center of machine” takeaway conveyor that provides for a single-point container exit. Servo electric calibration stations with self-adjusting height compensation allows for consistent shear ring cutting.
In addition, Siemens IPC477E Industrial PC with 15.0-in TFT touchscreen provides for an intuitive controls system that is focused on easy navigation. Meanwhile, remote access of the machine for technical support is achieved via an Ewon system, which is easily integrated within a customer’s IT system.
MAX Series Single-Screw Extruders
At its booth in NPE, R&B will also display one of its standard 3-1/2” x 32:1 L/D MAX Extruders with a vented-to-atmosphere barrel.
This extruder includes standard Allen-Bradley Compact Logix-based controls with a 15.0-in TFT touchscreen. The control system allows for simplified integration of various downstream equipment so long as the downstream equipment is configured with the proper electrical components.
Optional features include a Nordson Hydraulic Screen Changer with extruder base mounted Hydraulic Power Unit. The MAX Extruders are available in sizes as small as 1-1/2-in to 10-in diameter.
