Twin Screw Extruder Screw Configuration
COWELL applies Europe origin high torque gearbox for its CWT-Mega twin screw extruders. The quality and durability are more convincing to our customer who requires higher standard twin screw extruders for their application. There are some trustable and famous good quality gearbox brands we have cooperated with, such as Zamebllo, Henschel, PIV, etc.
The HIP material, which originated in Germany or the USA, is 4 times more wear-resistant than that common metals. In order to meet the requirements of good durability of screw and barrel, some higher quality materials will be used in our CWT-Mega twin screw extruder as well as CWT-Plus twin screw extruder to make the screw and barrel more wear-resistant, reduce the replacing time for the customer which can enable customer not only running the machine continuously but also save the maintenance time.
With a Europe high-quality gearbox, the Europe origins safety clutch is a must for the extruder. The quality, accuracy, torque and action time of Europe origins safety clutch are excellent enough to make sure your twin screw extruder is well protected when gets emergency incidents.

All the extruders will be well-packed by wooden boxes, further more, in order to avoid the rust of extruder parts, we will use the anti-rust oil for the screw & nuts which are easily get rusted during the sea freight, after that a plastic film will be wrapped around the extruder and other auxiliaries. With those well protection, we can make sure the extruder get to customer site at a brand new situation.
We have different steps to reach the final proposals
Step 1, we need customer to provide a basic needs information for the extruder, The raw materials they are gonna process on our extruder, a basic formula provided will help a lot for the proposals. The throughput they prefer to get from our extruder. For what purpose of the final products be used after get from our extruder.
Step 2, Our team will prepare for a basic proposal for the customer reference, if the customer have different ideas, we can discuss with each other to optimize the proposal until they are satisfied.
