— a machine for work — an exceptionally reliable “workhorse,” easy to operate and perfectly suited for the shop floor and its operators. — customization — the option for modifications and adjustments according to customer needs, performed locally and supported in Hebrew. — engineering precision — combining precise dosing engineering with advanced control technology for wide-ranging applications. — advanced support — a modern connectivity interface enabling rapid and efficient remote support and OTA updates.
Exclusive Katzenstein machines from Polyurethane Ltd. constitute an ideal machinery solution for the industrial shop floor, serving as a robust and reliable workhorse refined through decades of customizing, maintaining, and operating this unique equipment across diverse factories. The machines are custom-made and designed to meet the shifting dynamics of the modern production floor. These systems combine precise dosing engineering with advanced control technology, allowing for a wide range of applications — from casting rigid foams and elastomers to the implementation of fully automated injection systems. Machine design focuses on process stability, operational efficiency, simple maintenance, and high MTBF (mean time between failures).
Casting and injection machines form the core of the polyurethane industry’s shop floor operations. These systems are designed for efficient and precise industrial manufacturing through simple operation, accurate component dosing, optimal mixing, and controlled injection into molds or continuous production lines. We provide machinery solutions that enable stable, repeatable, and efficient work across a vast array of industrial applications, customized to the customer’s specific manufacturing process.
Control Systems and Technical Features
The machines are designed for continuous operation while maintaining production process stability: — precise flow and dosing — advanced dosing systems that maintain an exact mixing ratio between polyurethane components (primarily 2-component, but 3-component versions and higher are also available). — mixing technology — dynamic mixing heads optimized for creating a high-quality, homogeneous chemical reaction. — wide material compatibility — ability to work with diverse material systems — from rigid and flexible foams to elastomers and compact casting systems. — parameter control — advanced digital command for full control over temperatures, working pressures, pouring programs, and more. — industrial durability — massive design intended to withstand high production loads over time, specifically suited for heavy-duty operation. — remote support — reporting of any deviation from defined parameters to support personnel enables rapid assistance and prevents production failures; a modern interface allows for OTA updates and remote support.
Automation Levels and Production Line Integration
Machinery solutions are custom-made to the customer’s requirements and can be integrated into several work configurations: — manual casting stations — ideal for small production series, complex molds, or products requiring operator involvement and guidance. — semi-automatic systems — integration of support arms and smart injection heads that optimize work and reduce physical effort. — automated production lines — full integration into continuous production setups, with synchronization capabilities for robotics, conveyors, and mold carousels.
Industrial Applications The systems are used for a wide range of manufacturing processes, including:
- rigid foam casting — manufacturing of refrigerators, doors, shutters, solar collectors, water boilers, and more.
- flexible foams — manufacturing of foamed upholstery parts, seats, and integral skin.
- manufacturing of insulated panels — continuous or discrete filling and injection of doors, cold store walls, and structural elements.
- elastomeric parts — casting of wheels, industrial seals, shock absorbers, and technical components requiring high abrasion resistance.
- filling and sealing — controlled casting (encapsulation) for the protection of electronic components and control systems.
Operational Benefits for the Shop Floor | Feature / Benefit | Technical Description and Significance | | :— | :— | | Uniformity and repeatability | precise repeatability in every injection cycle, contributing to the uniform quality of the final product. | | Robust construction | highly durable, allowing for heavy-duty operation by less-skilled personnel. | | Simple and easy maintenance | the machines are designed and built by the same team that subsequently maintains them, ensuring simple and easy handling. | | Waste reduction | savings in raw materials thanks to precise dosing. | | Seamless integration | ability to integrate injection and casting machines into existing infrastructure and production equipment at the customer’s site. | | Operational flexibility | rapid adaptation to various applications and easy transition between material types and molds. |
