Coating Process Creates Permanent Slick, Dry Surface



Surface Modification

Coating Process Creates Permanent Slick, Dry Surface

The coefficient of friction of natural and synthetic elastomeric materials can be reduced

MANUFACTURERS AND USERS of plastic and rubber components can create a bonded slick, dry surface using a new coating process. Developed by Coating Technologies Inc. (Scotch Plains, NJ), the biocompatible LubriCoat coating reduces the friction on the surface of any synthetic or natural elastomeric material. The process creates a coating that does not crack, peel, or flake off; adds no significant weight; and will not affect the tensile strength, elasticity, compression, or durometer of the material it is applied to. LubriCoat can be used on parts such as seals, tubing, valves, and O-rings, eliminating the need to spray them with silicone.

The coating process is performed in a continuous batch operation. Prior to application of the coating, the elastomer surface is cleaned and specially prepared for bonding. The LubriCoat polymer is then applied, cured, and inspected. Fast, automated batch changeovers accommodate a variety of different component sizes and shapes.

Coating Technologies provides a contract coating service. For large production output, or for products that require greater control and monitoring, a custom turnkey package is available for in-house use.

Imaging

Microminiature Camera Compatible with a Variety of Heads

Applications include endoscopy and microscopy

SUITABLE FOR ENDOSCOPY and microscopy, the IK-M43A microminiature camera by Toshiba (Irvine, CA) is compatible with 1/2- and 1/4-in. camera heads, as well as with standard C-mount lenses, without the use of an adapter.

The camera outputs S-video and composite (NTSC) signals and features a 410,000-pixel CCD image sensor, a newly designed microlens for enhanced low-light sensitivity, and 470-line resolution. Digital signal processing enhances image quality. An RS-232 interface allows PC control of the camera's CCU.

Other features include automatic tracking of white balance, an auto shutter mode that controls light from 1/60 to 1/50,000 of a second, and simultaneous Y/C and composite outputs.

For more information, call Toshiba at 708/482-0972.

Testing Instruments

Dual-Channel Leak Tester Simultaneously Tests Two Parts

Allows higher production rates

A DUAL-CHANNEL leak-testing instrument increases productivity by simultaneously testing two parts or conducting different tests on the same part. The tester operates at high production-line speeds.

The new unit, made by InterTech Development Co. (Skokie, IL), is an enhanced version of the manufacturer's computerized M-1075 leak detector. It features extended memory, saving up to 1000 test records for display, printout, or downloading. In addition, it can perform statistical calculations on stored data to report mean, standard deviation, and mean ±3 standard deviation for statistical process control and other quality management programs.

The leak tester's design combines mass-flow sensing technology with microprocessor control for direct measurement of leakage rates, providing fast test cycle times of 0.3 to 2 seconds on test-part volumes ranging up to 25 cm3. This technology gives the new model a sensing range of up to 80 sccm and test pressures up to 100 psig. These features support a variety of applications involving products or components that must reliably contain a liquid, gas, or vacuum.

For more information, call InterTech Development Co. at 847/679-3377.
