Bry-Air Systems, a division of Bry-Air Inc. of Sunbury, Ohio, has introduced its MDS-3 portable mold dehumidifier. A chilled water pre-cooling system removes most of the humidity from the air. The air then is passed through a desiccant media to remove more humidity.
The dehumidified air can be conveyed to three molding ma-chines from a single dryer. The units include a one-year warranty.

Machine analyzer helps reduce costs
Minneapolis-based Nicollet Process Engineering Inc. is marketing a new Windows-based Personal Computer Machine Analyzer, developed with molding technology officials at 3M Co. in St. Paul, Minn.
The analyzer is available for injection molding, blow molding and extrusion. In a typical application, the analyzer creates a baseline ``thumb print.'' The data is stored, so that during maintenance or when problems happen, operators can compare current information to the baseline.
The system evaluates more than 60 parameters, including cycle time, clamp close time, ram velocity, cavity pressure and mold temperature. About 200 samples per second are taken from each of up to 16 analog and 16 digital channels.
The unit gathers statistical process control data. Nicollet said operators can be trained in a few hours.

Receiver geared for compounders
Premier Pneumatics Inc.'s Model 2420 Receiver, designed for compounders, handles pneumatically conveyed free-flowing resin pellets or powder.
A plenum-mounted halo air accumulator allows the unit to have pulse-jet, reverse-air cleaning. Four polypropylene felt-filter bags, totaling 12 square feet of surface area, receive air pulses after each delivery cycle.
Compounders use the 2420 Receiver to convey PVC compounds and other additives and fillers that are relatively free flowing. Premier Pneumatics is based in Salina, Kan.

HTP system allows higher temperatures
The Buffalo, N.Y.-based Mokon Division of Protective Closures Inc. has introduced Duratherm HTP, a water temperature control system for temperatures to 300§ F, and a new, smaller Duratherm model.
The unit replaces the standard Duratherm stainless-steel pump with one made from cast iron.
The compact model measures 281/4 inches by 16 inches by 243/4 inches.

Despatch ovens help reduce part stress
Despatch Industries offers four annealing ovens, the PA Series, for rapid annealing to reduce residual stresses in plastic parts.
The ovens have a high-volume, ``vertical up'' airflow to give uniform temperature and reliability. A recirculation blower and adjustable-supply air louvers give fast heating. The Minneapolis firm said PA ovens are an alternative to radiant ovens, especially for products with complex shapes and varying wall thicknesses.

Entoleter offering 2 new granulators
Entoleter Inc. of Hamden, Conn., has introduced two Series 25 granulators for grinding large parts.
Model 2537 has a maximum throughput of 2,500 pounds an hour. Model 2549 can granulate 3,500 pounds an hour.
Entoleter said the machine's cutting chamber is easy to reach for replacing knives. A double-shear cut reduces energy consumption and reduces fines.

Polyclad software simulates die design
PolyDynamics Inc. of Hamilton, Ontario, offers Polycad software to simulate extrusion and die design, and thermoforming.
The software family covers finite element analysis of flow analysis, extruder design, die flow simulation and die design.
The software covers a range of extrusion, including blown film, profiles, coextrusion, calendering and flat coat-hanger-type dies. Thermoforming software does finite element analysis of wall thinning during thermoforming.

Screen Tech offers hot-stamp printer
The Promax HS1 from Screen Tech Inc. of Oakville, Conn., is a fully automated hot-stamp printer for cylindrical plastic containers.
All machine functions are computer controlled. Other features include six-direction print head adjustment and a ball screw to eliminate backlash, two-color registered decoration and seam orientation.
