R&B extrusion units to come in 5 models
R&B Plastics Machinery LLC of Saline, Mich., has launched a line of continuous extrusion shuttle blow molding machines for bottles.
R&B is known for its wheel machines, which turn out containers at a high output.
The new continuous extrusion shuttle machines fit into the low-volume to midvolume output categories, the company said. The RB line of machines will come in five models, with clamping forces of 21/2-221/2 tons and the ability to run 32 cavities on an 85-millimeter center distance.
The machines are available in inclined and horizontal clamp configurations. R&B said the presses' parts can be interchanged with parts of some of the top machine brands in the market.
R&B's rapid entry into the market is a result of an agreement covering the Americas with a South African-based company, which has an installed base of 150 blow molding machines in South Africa, Australia and some Asian countries.
James Sheely, vice president of business development at R&B, said the South African company, which he would not name, will build components and subassemblies. R&B will do the final assembly in Saline.
Founded in 1980, R&B also makes extrusion blow molds, PET bottle molds and cold-end tooling at Monroe Mold in Monroe, Mich. The company bills itself as a supplier of turnkey systems.

MTM finishing units are multifunctional
MTM Systems, a division of St. Louis-based Lectro Engineering Co., said its 5000 series of plastic container finishing systems has integrated trimmers and reaming units, and can deflash and detab.
The line can handle any single- or dual-neck application. Each station is designed to customer specifications.
A modular design allows for combining trimming functions, depending on the project. The 5000 series can be retrofitted to work with other containers, the company said.
Walking beam technology and servomotors provide reliable container handling at high speeds, the firm said.

Two new gear pumps improve extruder life
For extrusion, Cumberland Engineering has introduced two new gear pumps: the MSDP standard-pressure pump and the MHDP high-pressure model.
The standard-pressure gear pump is designed for pressures up to 5,000 pounds per square inch and 345 bar. The high-pressure gear pump can handle pressures up to 10,000 psi and 689 bar.
By reducing the load on the extruder, both models enhance extruder life, boost output and reduce scrap.
Features include fast start-up, higher output and reduced scrap.
Cumberland is based in South Attleboro, Mass.

Quick-change device earns Brown patent
Thermoforming equipment maker Brown Machine LLC has earned a U.S. patent for a bayonet-style device that allows the quick changing of plug assists without the need for hand tools.
The plug assists can be installed or removed individually with a simple hand twist. When twisted to the locked position, the plug assist is held firmly so it cannot accidentally rotate to an unlocked position, according to the company.
Brown of Beaverton, Mich., said the bayonet concept can be incorporated into newly designed third-platen and conventional thermoforming tools. It also can be retrofitted to many existing tools.
Brown said the quick-change feature is running on several multicavity production tools that thermoform a range of small and large, round and rectangular single-service containers.

Conair offers robots in lower price range
Pittsburgh-based Conair Group has introduced its Axess line of three-axis, servo-driven robots.
The line costs about 25 percent less than other servo robots in its size range, according to the company.
Features include simultaneous motion on all three axes, multiple vacuum and pressure circuits to allow degating, selective part placement and wrist rotation to 180 degrees, with a programmable intermediate stop at 90 degrees.
Maximum speeds of 6.5 feet per second are achieved over a horizontal stroke length of 40-100 inches. Vertical stroke is 40 inches. The standard strip stroke is 13.7 inches.
The payload capacity is 6.6 pounds.
The icon-driven Axess control panel supports direct programming - the step-by-step creation of a robot cycle from scratch.
