Foam Extruder

Types Of Foam Extruders Offered

Our earth is facing various problems, such as air/water pollution, wastes, etc.Now the world come to realize the importance to protect our earth. COWELL is dedicated to try its effort to contribute as parts of the world, CO2 super critical foam technology is now widely used in our foam extrusion lines instead of HFC. As we know that HFC will damage the ozonorsphere while CO2,as a eco-friendly foam agent, has no such problem. 

Currently the CO2 super critical foam technology is used in our XPS foam extrusion, PET foam extrusion and PLA foam extrusion. We are developing more possibilities for the foam extrusion, making the products lighter and less usage of raw materials to protect our earth ultimately.

PET Foam Extrusion Line

PET-Foam-Extrusion-Line

PET foam board is low density, high strength, low water absorption, good performance in soundproof and heat insulation. As a structural foam material, the strength and stiffness will be greatly increased while the density keeps the same.

PLA Foam Extrusion Line

PLA-Foam-Extrusion-Line

As is known to us all, the plastic pollution is getting more and more serious all around the world. For the plastic dish plates, the whole world has more than 4 million consumptions, most of which is non-biodegradable.

XPE Foam Extrusion Line

XPE-Foam-Extrusion-Line

XPE is is a kind of chemical cross-link PE foam with closed hole structure. It is made by LDPE compounding with coupling agent and foaming agent with continuous high temperature foaming. Compare to EPE.

XPS Foam Extrusion Line

XPS-Foam-Extrusion-Line

Based on polymer extrusion process technology, polymer rheology and supercritical physical micro foaming technology as the forerunner.

Foam Extruder Features

PLA Foam Extrusion Line

We convey the Super Critical CO2 by a precise close-loop injection system, insuring the accurate conveying of the CO2 and it is at the super critical status.

Increase the mixing and dispersion screw elements to improve the capability and contact area of the CO2 and polymer, thus the mixing and dispersion will be sufficient.

The injection port is located at the second stage of extruder, It will prevent the back flow of CO2 which might causes the unstable to the system.

4.Accurate controlling for the screw speed and the temperature is essential to improve the melt pressure and viscosity, increase the solubility & dispersion of CO2.

PET Foam Extrusion Line

COWELL has achieved the PET foam board continuous extrusion with super-critical CO2 injection technology.

XPE Foam Extrusion Line

XPE foamed sheet is used in a wide range of applications, and COWELL provides project solutions for XPE foam sheet manufacturing.

XPS Foam Extrusion Line

Cowell Extrusion can provide the most mature supercritical CO2 injection system solutions in China, covering high and low CO2 injection process kits, and can provide customized solutions according to the actual needs.

FAQ

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.
