micropellets and TPEs, there is an advantage in underwater systems. And it’s a very simple system with a high level of automation.” IPS already has a cooperation agreement dating
back to January 2014 with Hanjin of South Korea to provide exclusive sales and service for Hanjin’s dry and underwater strand pelletizing systems in Europe. As a result of this agreement, IPS can now provide complete underwater strand pelletizing systems up to a working width of 1,200 mm and a maximum throughput of 18 tonnes/hour, the company says. In conventional strand pelletizing systems, the IPS range of products is extended to working widths up to 800 mm. Bay Plastics Machinery of the USA has released a

pelletizer. It says that only a few modifications, which can be made in around 15 minutes, are needed to change from water pelletizing to air pelletizing and vice versa. The unit has been designed especially for laboratory applications, where flexibility is particularly important. It can be used to test diverse materials and prepare for scale-ups, Econ says. “The EWA 50 is typically used with twin-screw
extruders up to 40 mm diameter,” says a representa- tive. “Most typical would be a 26-mm twin-screw. For every material that can’t be processed with water, the air pelletizer can be used, even materials that are hard to dry like natural fibre/wood compounds. For anything else the underwater configuration is used.” Intelligent Pelletizing Solutions (IPS) says that now

Niedernberg in Germany, it is well-placed to broaden its line-up. Company owner Gerald Weis says that a key reason for the move was to facilitate its expansion into the production of underwater pelletizers to complement its existing range of strand pelletizers. The first new system, the UWG 100 with a throughput of up to 600 kg/h, should be ready for launch around now. In mid-December, a prototype was already running in the company’s new technical centre. Weis says that the company plans to add a second
underwater pelletizer later, with a capacity of 2,000 kg/h. He says the development is the result of requests from users of IPS strand pelletizers keen to add underwater pelletizing but preferring not to change supplier. “The strand pelletizer is still the most flexible type, you can cut any polymer and its ease of cleaning is a big advantage for compounders making small lots, but the market is asking more and more for an underwater type and we are responding to that demand,” he says. “For some applications, like

new design for a cleated puller which targets the long-glass-fibre pultrusion market. It includes a heavy duty frame and robust drive components which provide a high level of performance and machine life. Ease of maintenance was also taken into consideration with a removable cleat system. The machine also provides even cleat wear to maximize cleat life and reduce maintenance down time. “This machine compliments our successful B-series pultrusion pelletizer very well”, says Jim Forgash, BPM sales vice president. “We can now provide an integrated solution to customers who want a puller and pelletizer. We can link the two machines, and provide a system that works well together. The puller is designed specifically for the high performance requirements found in today’s pultrusion market”. The machine provides up to 2,700 kg of pull force, and is available in custom lengths and widths. BPM has also developed a new light production/lab
pelletizer which will be unveiled at the 2015 NPE show in Orlando, USA. Forgash says that the BP 50 has a completely new design and is a light production machine with the flexibility and low cost of a lab line.
