RENITE GLASS FORMING LUBRICANTS
RENITE H MOLD OIL is a scientifically formulated mold oil - also oven chain lubricant, used around the world for more than half a century. It is a lightly graphited oil, uniform in quality and having excellent stability. When applied to a hot metal surface, the oil vehicle boils off cleanly to leave a silvery-black solid film lubricant. Its major use is in manufacture of pressware, tableware, kitchen ware, glass block, sealed beam lights, television tubes, and ophthalmic lenses as examples. It is the lubricant of choice for the Hartford 28 machine and is widely used by artisans and craftsmen in hand shops. In automatic and semi-automatic operations, RENITE H is applied in precise, carefully controlled quantities after each piece is formed, with equipment such as the RENITE E Model Atomizer and RENITE Rotator. In hand shops it is applied with a swab or oiler can after every three to five pieces. It is also used on IS Machines wherever just a light touch of a rather clean lubricant is needed - to finish mold tops, bottom plates and rings. It is an excellent lubricant for hinge pins, for bearings and chains in fiberglass manufacture, and for high temperature conveyers. Similar, but with higher graphite content, is our RENITE #45 .
RENITE CH SMOKELESS MOLD OIL. Similar to Renite H, but with a synthetic base oil that forms non-condensible vapor rather than smoke that will later condense. One air sampling study showed a more than 17:1 reduction in smoke (oil mist) on switching to Renite CH from Renite H. Especially clean. More expensive, but goes further, one part often being equivalent to three or four parts of Renite H.
RENITE F-72 (heavier) and RENITE F-95 (lighter) SEMI-FLUID BLANK MOLD LUBRICANTS. Though designed for use on blank molds, some use them on rings, finish molds and bottom plates also, varying the wetness of the swab. These RENITE lubricants have a semi-fluid consistency and handling characteristics similar to products in common use, but have certain advantages, including less smoke, greater cleanliness - particularly less marking of ware when swabbing, less spattering (goggles stay cleaner) and ability to swab more sections before rewetting the swab. They are priced very competitively. (Examples: RENITE F-72 used for beer and beverage; RENITE F-95 used for cosmetic and pharmaceutical ware.)
RENITE F-5 PASTE-TYPE BLANK MOLD LUBRICANTS. Extra cleanliness is possible with RENITE F-5, but it does require a little more care and practice in handling. More paste-like than most other such lubricants, RENITE F-5 needs a little stirring before use - which makes it more fluid and easier to handle. One of the earlier RENITE developments, RENITE F-5 is useful for older equipment - Lynch Machines - and also shows promise as a lubricant in certain Heye process operations.
RENITE RING LUBRICANTS. Our basic ring lubricants are RENITE H-8-A and a later, slightly different version, RENITE H-9 which are more fluid equivalents of our new lubricants for blank molds. These RENITE ring lubricants are closely related to the homemade mixtures your operators are using, but homogenized and stabilized - no chunks of sulfur to burn pits in your rings or lumps of graphite or blank mold lubricant to smudge the rings and mark ware. These ring lubricants are particularly useful as remedies for the “hollow neck” problem in narrow neck press-and-blow operations (too-thin glass in the neck area). For less difficult jobs, some continue to use our earlier products RENITE F-760 (paste-type), its semi-fluid equivalent, RENITE F-770, and our double strength ring lubricant, RENITE F-747. For light neck ring lubrication, (e.g. baby food and mayonnaise jars, where cleanliness is very important) try RENITE H.
RENITE CHEK-NO-MORE ANTI-CHECKING COMPOUND. A thick, paste-type lubricant applied to finish molds to prevent checks. It is rubbed into a swab until only a trace of liquid is on the swab surface, and is applied very lightly to finish mold shoulders, neck rings and bottom plates. It is noted for its cleanliness. We have a similar product, with sulfur added, called RENITE CHECKSTOP 10.
RENITE SLIDE D-10 DRY DELIVERY EQUIPMENT COATING. A heat-resistant coating for the chutes, troughs and deflectors through which the gob travels on the way to the blank mold. This is a two-component epoxy coating containing graphite. Hardening begins when the components are mixed, and is complete in about 6 hours at room temperature. Special feature: It is self-leveling, so that brush marks disappear, and a smooth, uniform coating, with extra lubricity and longer life due to its smoothness, is formed.
RENITE RW-1 SCOOP LUBE. A clean oil with very low carbon residue - applied as a fine mist on scoops for added lubricity. Helpful on certain newer machines.
RENITE D-5-A SHEAR SPRAY CONCENTRATE. A good, all-climate shear spray concentrate. It contains no fatty materials to coagulate and cause clogging on chilly days. Typical dilution is 150-300 to 1.
RENITE D-9 PREMIUM SHEAR SPRAY CONCENTRATE. A water-soluble fatty oil - forms an emulsion with good stability in cold water. High dilution ratio - 500-700 to 1. (For certain special purposes we also offer a synthetic shear spray concentrate containing no animal, vegetable, or mineral oil.)
RENITE MOLD PASTES. These are used on molds in the specialty glass industry (hand blown and semi-automatic blown glassware; Hartford 28 operations) for manufacture of high quality tableware, decorative ware, lighting fixtures and similar items. Molds are pasted, dipped in cork powder, baked and then rubbed smooth with a hot gob of glass, then dipped in or sprayed with water before blowing. If interested in such products, ask for details. Supplied in several viscosity grades, with and without graphite. Ask for details.
RENITE GRAPHITE-WAX STICKS. The RENITE G-STIK (softer, lower melting) and RENITE GL-STIK (harder, higher melting) are our most popular - we have several others. Some iron molds in the specialty glass industry are normally used without a lubricant or coating. When sticking occurs, these sticks are rubbed on trouble spots. They are also rubbed on hinges and on the plates on which the molds slide. The RENITE GL-STIK is especially useful on press molds for manufacture of tempered curved glass.
RENITE PH HIGH TEMPERATURE PENETRATING OIL. A graphited penetrating oil all for the specialty glass industry. It is used on mold and oven hinges, and on certain valves exposed to high temperatures.
RENITE S-24 LEHR MAT COATING CONCENTRATE is a graphited coating concentrate for spray or roller application to lehr mats and the transfer area between mat and the IS machine. It greatly reduces problems with rusting of mats and bottom checking of ware. The concentrate is diluted with five to ten parts of water and applied thoroughly but lightly, preferably at a point where the mat is slightly warm. A gallon of concentrate is roughly enough to coat a mat and the coating may last two or three days before reapplication is needed. On the transfer area, it is applied with a swab, full strength or diluted just slightly - often dramatically increases breakage resistance of ware. Some operators mix it with flour to form a thick black goop that serves as an excellent and lost-lasting coating for take-out tongs and other tools which contact hot glass products.
RENITE AKX PRECOATING is applied to blank molds and related equipment before they are put in service, drying to form a semi-permanent solid film lubricant coating that greatly reduces the frequency of swabbing while it improves glass distribution. Often, no swabbing is needed for an hour or two on start-up. It is easily applied at room temperature and requires no expensive baking in an oven. With a little practice your mold shop people can soon become “experts” in the spray application of this coating. RENITE AKX is also used as a mold coating in glass sagging operations.
OTHER RENITE LUBRICANTS FOR THE GLASS INDUSTRY. It is not possible to cover all kinds of RENITE lubricants in limited space. Certain RENITE products are special request items, used by only a few customers. If you have a special need, we may have a stock item that fits it and if not, we have capability, experience and willingness to develop one.
NEW RENITE DEVELOPMENTS. The glass industry is constantly in a state of change and RENITE COMPANY keeps up with the changes by means of a continuing program of research and development. We continue to work on improving the quality, effectiveness and economy of our present lubricants and on developing new lubricants to meet new needs as these arise. With over 70 years of experience, we stand ready to be of service.
