A better quick shut-off non-return valve for the Plastics Industry.
Injection molding applications require two important criteria from a non-return valve:
Rapid material shut off for part weight consistency
A smooth, high-flow profile to prevent material degradation.
The Glycon QSO® valve is the only valve that provides you both. The result is higher quality parts, fewer rejects, improved yield, and a better return on every pound of material you run.
Compared to traditional ball and ring check valves, only the QSO® Quick Shut-off Valve delivers both high flow and raid shut-off. Plastics molders prefer the QSO® because:
The QSO® ends short shots!
The QSO® reduces scrap rates
The QSO® optimize part weight consistency
The QSO® prevents material degradation
The QSO®is perfect for filled materials
The QSO® eliminates need for decompression or “suck back”

The BT Series shakers from Sentek Dynamics are designed for demanding vibration test applications. Typical applications included structural analysis, calibration and testing of smaller assemblies. The BT-100 through BT-400 shakers utilize light weight rare earth magnets in lieu of traditional Alnico magnets. The use of these magnets decreases the total shaker mass to a third of similar size system, making these shakers easy to handle and portable.
The systems range in size from 100 N (70 lbf) to 1000 N (224 lbf). Systems 400 N (99 lbf) and smaller are permanent magnet shakers and use lightweight rare earth magnets, making these systems easy to handle and portable. There are three versions of the BT Series of shakers: the BT, BT-M and BT-MTH.
The BT Series is recommended for vibration testing of small assemblies and components. These shakers have armature diameters from 60 mm (2.36 in.) to 120 mm (4.72 in.). The BT-1000 is equipped as standard with Automatic Armature Centering (AAC) and Air-Isolation Feet (AIF).
The BT-M and BT-MTH Series are our modal shakers lines. BT-M will use standard stingers while the BT-MTH is our through-hole version. On the 100 N and 200 N system the BT-MTH offers over double the displacement. The BT-MTH Series allow you to use piano-wire stingers. The BT-1000-M is ideal for the structural and modal analysis of high-mass structures. The addition of ZPR (electronic zero-point regulation and adjustable suspension stiffness) allows the user to pre-load the structure prior to applying a dynamic load.
The new Sentek Dynamics Bench Top and modal exciters are based upon years of practical experience. These systems all exhibit a high lateral stiffness and high force-to-weight ratio. They are specifically designed to help ensure the best possible performance with minimum setup time.
Induction heating is a fast, efficient, precise, repeatable, non-contact method for heating metals or other electrically-conductive materials . An induction heating system includes an induction power supply which converts line power to an alternating current, delivers it to a workhead and work coil creating an electromagnetic field within the coil. The work piece is placed in the coil where this field induces a current in the work piece, which generates heat in the work piece. The coil, which is water-cooled and cool to the touch, is placed around or adjacent to the work piece. It does not touch the work piece, and the heat is only generated by the induced current flowing in the work piece.
Induction heating is used in processes where temperatures are as low as 100 oC (212 °F) and as high as 3000 °C (5432 °F). It can be used in brief heating processes that are on for less than half a second and in heating processes that are on for months.
Induction heating is used in domestic and commercial cooking, and in many applications such as melting, heat treating, preheating for welding, brazing, soldering, curing, sealing, shrink fitting in industry, and in research and development.
Monitoring turbidity and haze of liquids and sheet is an indicator for product quality. Examples include: polymer extrusion, resins and chemical production. Real-time adjustments of the process parameters are therefore possible through immediate "off-specification" detection.
INTRODUCTION
Turbidity and haze measurement is a well-accepted technology to check the consistency some production processes. Usually these measurements are performed ‘off-line’.
The delay between sampling and obtaining the results from the laboratory can be time consuming. A significant disadvantage is that only a single measurement is generated in this time period and the concentration during, before and after the sampling point is unknown.
With the inline turbidity and haze measurements taking place directly in the process, not only is complete documentation possible, but when variations occur, immediate intervention can take place.
INNOVATION
The Equispec™ In-line Color Spectrophotometer (ICS) is a high performance instrument designed for use in an industrial pro-cess. Its excellent sensitivity and flexibility make it useful for process applications. The ICS and process probes are designed to be used in high-temperature, high-pressure and corrosive environments. It can be used to analyze liquids and solids.
The analyzer supports one or two probes with dedicated lamp compensation channels [all fiber-optic double-beam design].

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
