The feed screw is used in plastics extrusion to force melting plastic resin through a die into a mold to form a desired shape. As screw designs have evolved through the years, there are several generic categories.
Glycon Corporation, the industry leader manufacturer of high performance and innovative feed screws, has put together this white paper describing the classifications of feed screws used in the plastics industry.
One of the specific ways to speed development, quality testing, and analysis of polymers is the ASTM/ISO Method A Test using the Dynisco LMI5500 melt flow indexer. This test is used in order to determine flow characteristics of plastic melts are used in various plastic processing techniques, namely extrusion and injection molding.
The LMI5500 brings a new level of ease of use with its removable inspection plate, increased access for sample cutting, and improved touch screen. This device provides values on the melt flow rate melt volume rate and melt density of polymers to ensure that the conditions of production are at peak efficiency without sacrificing the quality of your products. Upon test completion results are viewable, and can be sent to the cloud. The information obtained from this test is important for achieving a quality product while maintaining a high level of efficiency in production.

Veterans Day is set aside to honor the men and women who have sacrificed so much in order to serve in the armed forces of the United States.
Veterans Day celebrates and thanks all United States military veterans, alive or dead, and honors the sacrifices that they have made. Our Veterans are our neighbors, friends, family, and co-workers. They took an oath to defend the United States and our Constitution, from all enemies, foreign and domestic. We must never forget their bravery, service, and sacrifice.
Originally called Armistice Day because of the November 11 Armistice that ended World War I, its name was officially changed in the United States in 1954 to Veterans Day to include Veterans of all wars.
Through the observance of Veterans Day, we remind ourselves of our Veterans patriotism, love of country and willingness to serve and sacrifice for the common good.
AP Corp. celebrates and honors America's veterans.
The Cox EC80 Flow Processor is a programmable electronic processor, providing total compensation to enhance flow meter accuracy, while extending the linear flow range. Packaging is provided for remote, direct or embedded mounting to support most installation or application requirements.
The compact design includes both single and dual frequency inputs from 4 or 10 ohm pickups, as well an RTD input and an additional analog input for other temperature inputs. The EC80 processor tracks all variables to compensate for viscous and inertial effects, using proven Strouhal-Roshko algorithms. Enhanced DSP technology allows for exceptional signal characterization using a 32-bit floating point processor at 150 MHz, capable of producing a 100 microsecond speed of response.
When bonding Micro-MeasurementsAdvanced Sensors Technology strain gage sensors (CEA, C4A, C5K) you want to ensure an excellent bond. The key element in bonding strain gages is surface preparation.
The video above demonstrates specific procedures and techniques with proven advantages. By precisely following these carefully developed instructions (along with the requisite procedures for gage and adhesive handling), the result will be strong and stable bonds. This video presents a procedure that is simple to learn, easy to perform, and reproducible. Keep in mind, it is very important to pay attention to detail and follow the instructions precisely. The importance of surface preparation for strain gage bonding cannot be understated.
1) Degreasing
Rigorously degrease the gaging area with a good solvent, such as CSM Degreaser or GC-6 Isopropyl Alcohol. Be aware though that some materials (e.g., titanium and many plastics) react with strong solvents. Make sure your solvents do not contain any contaminants
2) Abrading
Preliminary dry abrading with 220 or 320-grit silicon-carbide paper is generally required if there is any surface scale or oxide. Final abrading is done by using 320-grit silicon-carbide paper on surfaces thoroughly wetted with M-Prep Conditioner A; this is followed by wiping dry with a gauze sponge. Repeat this wet abrading process with 400-grit silicon-carbide paper, then dry by slowly wiping through with a gauze sponge. Finish with 320 grit on most steels and 400 grit on aluminum alloys.
3) Burnishing of Layout Lines
Using a 4H pencil (on aluminum) or a ballpoint pen (on steel), burnish (do not scribe) whatever alignment marks are needed on the specimen.
4) Conditioning
Repeatedly apply M-Prep Conditioner A and scrub with cotton-tipped applicators until a clean tip is no longer discolored. Remove all residue and Conditioner by again slowly wiping through with a gauze sponge. Never allow any solution to dry on the surface because this invariably leaves a contaminating film and reduces chances of a good bond.
5) Neutralizing
Now apply a liberal amount of M-Prep Neutralizer 5A and scrub with a cotton-tipped applicator. With a single, slow wiping motion of a gauze sponge starting within the clean area and wiping outward in one direction. Repeat the wiping step with a clean gauze pad, again, start in the clean area, wipe though the gage location moving outward in a single stroke to fully dry this surface. Do not wipe back and forth because this may allow contaminants to be redeposited.
For proper outcomes, the procedures and techniques presented here should be used with qualified installation accessory products from Micro-Measurements, namely:
CSM Degreaser or GC-6 Isopropyl Alcohol
Silicon Carbide Paper
M-Prep Conditioner A
M-Prep Neutralizer 5A
GSP-1 Gauze Sponges
CSP-1 Cotton Applicators
PCT Gage Installation Tape

The SV 200A is a Class 1 sound level meter integrated with a wireless communication via 3G, LAN, Wireless LAN and Bluetooth®. The list of add-ons also includes a built-in electrostatic actuator, GPS module and e-compass. The waterproof power supply is also provided.
The SVANTEK SV 200A is the top-of-the range noise monitoring station with built-in microphones for noise directivity detection. This innovative, new product enables the identification of dominant noise sources providing information about their location both vertically and horizontally. In practice, measuring directionality gives the opportunity to indicate the dominant source of noise in the measurement area or exclude unwanted events.
Four additional microphones located on the sides of the housing use the sound intensity technique to recognize both the vertical and the horizontal direction of a dominant noise source. Leq distribution in angle sectors is saved as time-history and can be used to filter and report data.
The SVANTEK SV 200A can perform a 1/1 and 1/3 octave frequency analysis in real-time and store it as time-history data. It can also record the audio signal for the recognition of noise sources and recalculation of the data.
The advanced alarm function can send email and SMS notifications caused by threshold levels and time events. Status alarms of the SVANTEK SV 200A are also available.
The 3G modem, Wi-Fi and LAN features provide fast Internet transfer to PC with standard internet connectivity. SvanNET enables Internet plug & play and easy management of measurement projects. Irrespective of the type of a public or private sim card, SvanNET will make a connection to allow full access to your data via Web browser. The Bluetooth ® and Wireless LAN features provide a point of access for easy SvanNET application configuration.
