The plastics industry relies on robust, high-performance pumps to support a variety of manufacturing processes—from raw material handling to extrusion, cooling, and waste recovery. Pumps must cope with viscous polymers, abrasive additives, and elevated temperatures, all while maintaining precise flow control. Whether in injection moulding, compounding, or resin manufacturing, efficient fluid handling is key to product quality and process uptime.
Key Applications
1. Polymer and Resin Transfer
Raw polymers, liquefied resins, and additives are transferred from storage tanks to processing equipment. Progressive cavity, gear, and diaphragm pumps are commonly used for their ability to handle thick, sticky materials without clogging or excessive shear.
2. Extrusion and Compounding Support
Pumps are used to feed plastic melts, masterbatches, and filler materials into extruders and blending systems. These applications require precise control over flow rate and pressure, with pumps capable of continuous operation under high-temperature conditions.
3. Cooling and Heat Transfer Circulation
Cooling systems are vital to control temperatures in moulds and processing lines. Centrifugal and multistage pumps circulate water or oil-based coolants to maintain consistent thermal conditions, essential for moulding precision and surface quality.
4. Chemical Dosing and Additive Injection
Plastic products often incorporate dyes, UV stabilisers, antistatic agents, or flame retardants. Metering pumps ensure precise dosing of these additives to achieve uniform dispersion and consistent performance.
