Product DescriptionProduct IntroductionIntroductionUnderwater pelletizing is a high-end, continuous process primarily used in large-scale polymer production. Unlike strand pelletizing, the cutting happens directly in a temperature-controlled water chamber, immediately quenching the molten plastic.Key Features & Function:Integrated Process: Molten polymer is extruded through a die plate and cut by rotating blades submerged in a water chamber.Instant Quenching: The hot pellets are cooled and hardened immediately upon contact with the process water.Closed Loop: The water and pellet slurry is transported to a centrifugal dryer for efficient separation, resulting in dry, ready-to-use pellets.AdvantagesSuperior Pellet Quality: Produces perfect, uniform spheres with minimal dust or fines, excellent for free-flowing applications.High Capacity: Designed for very high throughputs (several tons per hour), ideal for continuous world-scale production lines.Material Versatility: Excellent for handling sticky, tacky, or heat-sensitive polymers (e.g., TPEs, certain nylons) as water prevents agglomeration and rapid cooling minimizes degradation.Oxidation Prevention: The water layer acts as a barrier, protecting the molten polymer from oxidation.Clean & Automated: A fully enclosed, dust-free system that supports high levels of automation for consistent product quality.Key attributesModelScrew Dia(mm)L/DScrew S(r/min)Main PowerOutput(kg/h)WS-505032-60500-60045-90120-400WS-656532-60500-60075-160200-850WS-757532-60500-600110-250300-1250WS-959532-60500-600250-550750-2750Fill modification:PP, PE, PS, EVA+ calcium carbonate, talc, titanium dioxide, carbon black, etcMasterbatch:PP PE PS ABS EVA PET and other + pigments and additivesFunctional masterbatch:Flame retardant masterbatch:ABS, EVA, etcPE, PP, PS and other degradable masterbatch were filledAll kinds of thermoplastic elastomers:TPE, TPR, TPU, TPV and other thermoplastic elastomers,EVA hot melt adhesives, etcMain productsCompany ProfileWecoex Machinery Co., Ltd. is a manufacturer specializing in complete plastic extrusion equipment, located in Zhangjiagang, Suzhou — a key hub of China's manufacturing industry. With years of expertise in the plastic extrusion sector, our main product lines include: 1. Plastic Pipe Extrusion Lines: For PVC, HDPE, PPR, CPVC, and other materials, supporting a wide range of applications such as water supply and drainage pipes, gas pipes, electrical conduits, underfloor heating pipes, and irrigation systems. 2. Plastic Recycling & Pelletizing Lines: Suitable for recycling both rigid (HDPE bottle, PET bottle) and soft plastics (PP bag, PE film), as well as mixed plastics, helping customers reduce raw material costs and achieve sustainable production. 3. Auxiliary Equipment: Mixers, shredders, crushers, loaders, haul-off and cutting machines, and stacking/packaging systems, offering customized support for various production needs. Our machinery serves municipal water and gas pipelines, power and communication conduits, agricultural irrigation, industrial drainage, and plastic recycling sectors.Equipped with advanced CNC machining, Siemens PLC controls, and rigorous quality checks, we ensure high-precision and reliable performance. All lines undergo full-load testing before delivery. Exporting to over 30 countries across Southeast Asia, the Middle East, Africa, South America, and Europe, Wecoex offers end-to-end services from design and customization to installation and aftersales. We are committed to providing efficient, energy-saving solutions and building long-term partnerships with global clients.Company AdvantageOur ServicesExhibitionPackage and ShippingFAQ1. How do you make the quotation for clients? The quotation depends on customer's raw material and capacity, If possible, please let me know your budget range so that I can recommend the most correct equipment for you with suitable price. 2. How long does it take from manufacturing to final inspection? Typically, our pelletizing lines have a production lead time of 2 months, while washing lines require at least 3 months depending on the capacity and umber of machines in the order. 3. What payment terms do you accept for first-time buyers?30% as down payment by T/T; 70% by T/T before delivery and after inspection 4. Do you have any after sales service? When all the equipment are completed, we will connect all the machines and run the full production line for inspection to ensure the stable running in customers' factory.After the commissioning, we will package the equipment by the standard export package for shipment.After appointment with the customer, our engineers will go to the customers' factory for installation and training. Engineers, sales managers, and after-sales service managers will form an after-sales team, online and offline, to follow the customers' project.
