Sheet Extrusion Features

Bio-degradable Material Sheet Extrusion Line

Special twin screw tech instead of pre-dryer+ single screw to save energy cost

Super strong vacuum degassing system is used for the line.

Accurate temperature controlling system.

PC Sheet Extrusion Line

COWELL Extrusion has intensive experience in PC sheet extrusion based on its R&D technics.

The standard level of power consumption, intelligence and degree of automation of PP/PC corrugated sheet extrusion production line, is in the front of the industry.

The complete after-service system, from machine installation and testing to the production of high-quality sheets, provides lifelong technical support.

PET Sheet Extrusion Line

With COWELL technology the shear heat generated by screw rotation is minimised.

With our uniquely designed auto winding system, the line speed for PET could be up to 90 meters/minute.

The complete line is controlled by PLC. Adopt SIEMENS frequency servo controlling system and ethernet transmission technology to achieve high efficiency, high precision, high stability and high security.

PP/PS Sheet Extrusion Line

The quality and capacity could be warranted by our ideal screw profile design and other components optimized.

The line is controlled by PLC and HMI. Which makes the whole line more intelligent, and could change the parameters on HMI for the whole system. All that we do is just to make the line running more accurate, efficient, stable and convenient.

COWELL team is extraordinary experience in various applications based on their rich working experience in the past decades. We could give perfect solutions to your requirements with our know-how on extruder design and material processing.
The most important is that a customized solution on your extruder project is available for you from our team. Any difficult process could be done on our lab extruder and analyse the possibility to make it succeed on the scale production extruder. Some special design which helps to make the qualified product are available here from us.
We not only provide extruder, but we provide the whole turn-key system for you. Making your product more competitive on the market. We create value for you.

We are extruder producer, and our customers have different requirements and abilities to afford the extruders. So we divide three types of twin screw extruders with different torque levels to meet the specific requirements for the customers with different requests.

Firstly, all the extruders sold will be guaranteed by COWELL. We will 12 months warranty after commissioning in the customer plant. And if customer delays to the start-up of extruders, we can make the guarantee time up to 18 months.

Secondly, COWELL team will use the best quality parts for the extruder, all parts will be strictly inspected before installed on your extruder. The quality, accuracy of parts could be guaranteed before installation.

Thirdly, when the extruder dispatched, all the designs, drawing, extruder specifications, will be filed , this will be very much helpful to capture all the details when we need to services for your extruder.

Forthly. All extruders delivered to customer will go with our detailed instruction manuals, including pre-start check up, operation steps, electrical check up, trouble shooting, etc. Customer could easily find out where the problem is, and reset the machine.

Lastly, we have on-line English speaking service engineers to guide you how to do the trouble shooting if you can not solve it. They are not only capable of solve your problem, but also you can get very valuable advice from them when you wanna do some new products.

Lead time varies according to the extruder model, applications and complex of the extruders
Normally we have large stock for the standard extruder parts, that will be done within a very shot time. If the machine is a totally customized, we need to confirm all the details before production in case any small mistake which could affect the final quality of the extruder. The possiblle lead time will be discussed between both parties.
We have different choices for transport of the extruder, sea freight, railway freight, air freight.
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. During the discussions, more detailed information needed from customer,that depends on the different applications.

We have plenty of extruder parts in stock, for the standard parts, we can deliver them immediately by DHL. Customer could receive them with a very few days.
For the non-standard parts, we will produce them as priority, making the delivery time as fast as we can.
We normally give advice on spare parts list when quote the extruder, customer could select them according to their needs.

During the pandemic, we have updated our extruder connections, just to make sure customer could make it running easily and conveniently.
The extruder and auxiliaries will be carefully tested before delivery, we will send testing video to customer to show that the extruder is tested. If there is any problem, we will solve it immediately.

All the wire/cable connections will be by a fast aviation plug, customer dont need to connect those cables one by one, just plug in/out.

For PLC/ HMI control, we have remote control for the customer, if customer have any trouble on the machine operation, we can help to solve remotely.
