Kelongwell 40D Twin Screw Water Strand Pelletizing Line Boosts Efficiency & Quality For Spanish 3D Printing Material Manufacturer
Kelongwell 40D Twin Screw Water Strand Pelletizing Line Boosts Efficiency & Quality for Spanish 3D Printing Material Manufacturer
The global plastics processing industry is moving faster toward high-efficiency, energy-saving and precise production, especially for 3D printing materials-a sector that's seen steady growth across Europe. Twin screw extruders are the core machine for making high-performance 3D printing filament pellets, and their quality directly shapes a manufacturer's output, product consistency and ability to compete in the market. Kelongwell has focused on researching and making twin screw pelletizing and extrusion equipment for years, and we've built trust with global clients by offering custom, reliable solutions that fix real production problems. This case shares our work with a top 3D printing material maker in Spain, featuring our 40D Twin Screw Water Strand Pelletizing Line with a special industrial water chiller, and how this custom setup improved their high-end 3D printing consumable production.
Our client is a well-known 3D printing material manufacturer based in Spain, focused on developing, producing and selling high-purity 3D printing pellets, including PLA, ABS and PETG. These materials are sold to both industrial and desktop 3D printing markets all over Europe, used in automotive parts, aerospace prototypes, creative design and educational tools. As demand for high-quality 3D printing consumables boomed in Europe, the client's old pelletizing equipment held them back: it couldn't fully plasticize heat-sensitive materials, leading to frequent thermal breakdown and brittle filaments; uneven cooling made pellets inconsistent in size, and each batch varied too much; low output and high energy use also meant they couldn't fill large orders on time. These issues led to an 8.2% defective product rate, constant delivery delays, and hurt their reputation in the competitive high-end market. After checking extrusion equipment suppliers worldwide, testing samples and comparing technical plans, the client chose to partner with Kelongwell, drawn by our industry expertise and custom solution options.
To fix the client's key production problems, Kelongwell's technical team talked closely with their team to learn about their material traits, daily production process and output goals, then created a custom 40D Twin Screw Water Strand Pelletizing Line with a matching industrial water chiller. Built specifically for heat-sensitive 3D printing materials like PLA and PETG, this line uses a gentle plasticizing, low-shear screw design. This setup avoids material damage while making sure raw materials and additives mix evenly. The water strand pelletizing system works with a precise industrial water chiller to keep cooling temperature and pressure steady, which fully fixes common issues like misshapen pellets, sticking and uneven sizing. The line also has an intelligent PLC control system and segmented temperature control, so operators can adjust production settings in real time to keep each batch consistent, meeting all European quality standards for 3D printing materials.
Once our team finished professional installation, testing and trial runs, the 40D twin screw pelletizing line started full production, and brought clear, comprehensive improvements to the client's operations. Key production numbers show obvious progress: materials plasticize much more evenly, 3D printing pellets have the right fluidity and toughness to meet European industrial standards, and the defective rate dropped sharply from 8.2% to under 1.5%. Hourly output rose 35% compared to their old machines, greatly increasing daily production capacity, cutting delivery times and ending delays for good. The optimized transmission structure and precise water cooling system also cut energy use per unit by 22%, lowering long-term production costs significantly. The line is also far more stable than average industry equipment, running nonstop for much longer periods, which reduces downtime for maintenance and keeps production flowing smoothly.
Kelongwell offers full-range service to global clients beyond just delivering high-quality machines. Our technical team traveled to the client's factory in Spain to oversee on-site installation, testing, and provide hands-on training for their local staff. We taught the team how to operate the line properly, maintain the water chiller daily, adjust the water strand production process, do routine upkeep and fix common small issues quickly, so they could run the line efficiently on their own in no time. The client's production director spoke highly of our solution, saying the 40D Twin Screw Water Strand Pelletizing Line solved the production problems they'd struggled with for years, helped them secure long-term orders with top European 3D printing brands, and strengthened their leading position in the industry. The client also confirmed Kelongwell will be their only equipment supplier for future production expansion.
This project shows that matching equipment performance to the specific production needs of the material is the key to success in specialized pelletizing. 3D printing materials need higher precision, stability and consistency than regular plastics, so they require custom-made extrusion and cooling equipment. Kelongwell always puts client needs first, keeps improving twin screw extrusion and pelletizing technology, and offers tailored solutions for 3D printing materials, color masterbatches, plastic modification and recycled plastics, helping manufacturers around the world make better products, work more efficiently and cut costs.
As the global 3D printing market keeps expanding, efficient, energy-saving and smart pelletizing equipment will be the key to staying competitive. Kelongwell will keep investing in research, upgrade twin screw extrusion technology, collect more successful overseas cases, and offer targeted solutions for clients worldwide. If you're a 3D printing material manufacturer dealing with low output, poor pellet quality, unstable cooling or high energy costs, get in touch with Kelongwell today. Our team will create a custom professional pelletizing line plan for you, boost your production efficiency and help you win more share in the global market.
