Quick-shift hydraulic die changers
Quick-shift hydraulic die changers Numerous products from the company are said to help extruders and recyclers produce better quality products more efficiently. The firm's quick-shift hydraulic die changer is said to utilize a quick-shift slide plate to exchange die heads on a single extruder. The patent-applied for system is said to be ideally suited for lines that must be purged during die changeovers, such as foam sheet operations or for batch operations where reduced changeover times translate directly to increased output and cost savings for waste and labor reductions. The device provides a pre-heat zone for the new die and utilizes a hydraulic power unit to shift the die online, effectively reducing changeover times from one hour to one minute. Designed for tight spaces, the current model will accept 12" and 18" annular dies. Custom versions are available for virtually any extrusion process, such as pipe and profile, where dies are routinely changed out. This company is a supplier of polymer filtration equipment, gear pumps, static mixers, divert valves and engineered system solutions for the polymer processing, plastics extrusion and recycling industries. All of the company's machinery and equipment is designed and manufactured in the USA to ISO 9002 standards. The company's products include screen changers (continuous screen changers; discontinuous screen changers; continuous backflush screen changers; hydraulic screen changers; and manual screen changers); gear pumps (extrusion gear pumps; high pressure gear pumps; chemical industrial pumps; and fluoropolymer gear pumps); auxiliary equipment; control systems; services; and more.

Rubber extrusion heads
A broad variety of co-extrusion aggregates is offered by the company, starting from extrusion heads with two extruders, the CoEx 2, up to multiple extrusion systems enabling the extrusion of up to six different rubber compounds with the company's CoEx 5plus1. The portfolio includes the C-Clamp Head as well as the patented Hammer-Head and Y-Head. The chosen clamping system depends on the requirements and on the individual production routine of the tire manufacturer. The flow channels are matched for the customers' individual requirements and their products with the use of finite element flow simulation. The flow history of the rubber in the head is analyzed and adopted in order to achieve a constant swelling behavior at the head outlet and a uniform flow. The general goal is a material-independent flow channel design.

Twin screw extrusion
In a twin screw extruder, the mixing/blending of polymers/additives and devolatilization are mass-transfer operations dependent upon shear/energy that is being imparted into the materials being processed by rotating screws. Devolatilization refers to the removal of unreacted monomer, solvent, water and other undesirable materials from the process melt stream. Almost always, the twin screw extruder includes the provision for devolatilization; sometimes as a critical factor in the process, and sometimes as an after-thought, according to the company. Vacuum systems are often maintenance intensive. Each system component must be carefully specified for the intended purpose with regard to protecting the pump and cleaning/maintenance.

Advanced extruder control
Sophisticated co-rotating, twin-screw extruder technology is utilized to evaluate material batches and new custom compounds for performance and customer specification viability. Owing to substantial varieties of color, durometer and the wide-ranging performance properties required, monitoring every aspect of machine performance is said to be critical. This includes all temperatures, speeds, pressures and torque on the extruder itself, plus an underwater pelletizer, gear pump and multiple loss-of-weight feeders used on the line. A lab extrusion line is used for both process and product development assessment. A key requirement is the generation of all data in real time, as part of the management system to be used, as well as the condition monitoring system needed for predictive maintenance strategies being employed. On the company's machine, the control system comprises the software solution, drives and motors, the ability to monitor up to 32 separate temperature zones, touch screen technology on a 15" HMI and scalability on the drives.
