MAX 1800 Series Injection Blow Machine Line

Trouble-Free Operation and Easy Maintenance

R&B Plastics Machinery LLC, Saline, MI/USA, a manufacturer of blow molding machinery, single-screw plastic extruders, and extruder process screws, and a machinery rebuilder, has announced the launch of the MAX 1800 series injection blow molding (IBM) machine line. The launch marks R&B’s entry into the injection blow machine market. The company is already a leading supplier of extrusion blow molding (EBM) machines including wheel and shuttle systems.

R&B is introducing the MAX 1835 injection blow machine with a 135-ton injection clamp for production of a wide range of pharmaceutical and home and personal care bottles made of HDPE, LDPE, PET, SAN, and PP, among others. A bigger unit, the MAX 1880 with a 180-ton clamp, is in final design and is expected to be available in July 2016.

The MAX 1835 IBM unit features a broad range of improvements that enhance operation and minimize maintenance including an innovative trigger bar locking mechanism that eliminates wear components that require regular service. According to the manufacturer, the expected service life is four times that of competitive mechanical locking pistons. In addition, pre-fill valves for the injection clamp are externally mounted for easy maintenance and extra-large diameter transfer shafts provide long life and accurate position control thanks to a heavy-duty drive hub which is electrically driven for precise control. The five-inch tie-bar diameter for the injection clamp is larger than competitive models and resists breakage.

The MAX 1835 boasts a molding table which is plated for long wear and corrosion resistance unlike untreated competitive tables which are oiled and become oxidized. A high-density chrome finish minimizes damage when the mold slides in and out. A convertible cooling center of pressure provides maximum flexibility by simplifying the locating position for a customer’s competitive tooling.

The MAX 1835 consists of a rigid steel frame and table construction and a three-station tie-bar design keeps all hydraulic components under the molding table. An air-pressure assisted lift-up style operator’s gate offers maximum safety. This allows access to the control panel at all times. An integrated locking mechanism in the operator gate’s handle is safer than gates utilizing chains or cables that are prone to break and allow the gate to drop unexpectedly.

The new machine line is expected to reduce down time, decrease the cost of production, and is generally more cost-effective than competitive IBM models on the market. These key benefits are realized without sacrificing performance and reliability, according to the manufacturer.
