extrusion. - polycarbonate sheet uses
Among many extrusion exhibits, NPE is "Tool Time ".
Innovative designs have been introduced by suppliers of blow film, Fiat sheet and pipe mold (
Some of them were reported in our June, July and issues).
In addition, extruder, control and measurement systems are introduced at the exhibition
Including a system designed for Internet communication.
The new pancake mold for the "universal" film mold coex blowing film is said to be "not affected by the flow", which means that it applies to almost all resins regardless of the flow properties of the resin.
In addition, the regular division (Redi)
Died at Addex.
Boston, new processes
Promote high flow channel design while reducing internal pressure.
The mold to be processed can be made into a mold with a diameter of more than 15. , Addex says. This side-
Fed chips split the flow rate of each polymer into three times, resulting in eight flows being reassembled before the material exits the mold.
The only thing is that the diversion of each resin is stacked vertically, not on a horizontal plane.
It is reported that this new arrangement helps to minimize the separation force between mold plates.
Pancakes are made up of distribution rings inside the feed ring, rather than stacking each distribution ring on the top of the feed ring.
Rick von Kraus, president of Addex, said that in general, the polymer passes through fewer channels than traditional pancake molds, so there are fewer opportunities for polymer degradation.
Addex says it avoids the need to optimize the flow channel of a specific material through a unique diverter board that divides each polymer flow into the upper and lower halves.
Each half of the flow is subject to intermediate restrictions, dividing the flow into high and low.
Then combine the different traffic from the top and bottom, so that the high traffic from the top can meet the low traffic from the bottom, and vice versa.
Regardless of the material, the result is considered a uniform film gauge.
Addex has tested the mold with llldpe and dlp and started using metallocene resin.
The company is expected to launch a Redi device next year.
For additional cooling on the frost line for better bubble cooling, a New stacked air ring called Robert's Stack is offered as an alternative to internal bubble cooling.
From the future design company. Brampton, Ontario.
Each air ring has an adjustable gap and its own Blower.
The future design also introduces a bubble shell made of a transparent polycarbonate plate that can protect bubbles from ambient air temperature or "shadow heat.

Series molds, the first flat die from Cloeren Co
Orange, Texas, has a new qualifier.
It is reported that bar adjustment technology to eliminate leakage.
Cloeren says there is usually a gap in the die head of the throttle
The adjustment device can weaken the integrity of the mold.
Cloeren eliminates the need for two unique gaps
The bar system, part of the bar, enters the mold at 45 [degrees]
Inside the mold, tilt and push the fixed limit bar to clarify the pre-tightening.
Cloeren also updated its automatic mold

Cloeren achieves better thermal isolation of the regulating mechanism in two ways
The rod system, the heated rod pushes the second rod to adjust the mold lip.
In addition, the translation and heating rods are now installed further away from the lips.
The enhanced measurement system of the Internet-based extruder Fiat Net provides new Internet communication capabilities. The Pro.

Up to six scan frames can be controlled (
Compared to four in previous systems)
There are 18 sensors in each extrusion line. The 21-in.
The touch screen has a new zoom feature that allows you to observe more details of the rolling profile section.
In addition, the new is a 3D defect map of a volume to help split.
You can rotate the view and set the slice point with your finger.
The most unusual thing is the internet compatibility of the system. Pro.
Net is an "open" system based on Windows NT, TCP/IP network and Java programming language.
The Internet can be used for remote setup and troubleshoot, viewing multiple production lines from a single location, sending and receiving emails
Mail and access to and from the process line-Help with online video.
With the help of micro cameras, line operators can hold video meetings with process engineers or service technicians from NDC in another location.
The system will be commercially available in January.
The price of upgrading to existing NDC 25,000 and 6000 systems will start at about $8000.

The optical detection system uses a CCD camera to identify defects in dust particles, dirt, gels, insects, or holes.
The unit has a 10-kHz scan time.
Any off-data can be usedthe-
For example, the Windows NT system generates a shelf graphical interface for the defect map.
Depending on the length of the network and the size of the particles to be detected, the price ranges from about $100,000 to $500,000.
The faster tube mold changed the new tube mold head from the United States of Raleigh, Columbia, Maryland
, Designed to convert the time from 2-
3 hours down to less than 30 minutes.
Rollepaal has also introduced a new multi-layer pipe head designed to handle up to 80% of recycled resin at a speed of 2200/hour.
