microGLEIT DF 921N – The Product for More Performance

microGLEIT®is a leading supplier of dry film lubricants for fasteners. Intensive development work and the experience of many years of practice with products and processes result in a wide range of reliable “friction adjusters.” Lubricants are indispensable for adjusting the coefficient of friction to desired values and narrowing down the standard deviation of the friction values of modern connection elements. microGLEIT®DF dry films are mostly water‐based lubricant systems containing contain PE (polyethylene) and partly addi‐tives such as PTFE or wax. microGLEIT DF 921 is a water based suspension of microWHITE solid lubricants –no hazard labelling required. The transparent, semi‐matt dry film provides good lubrica‐tion properties. Additionally, the microGLEIT DF 921 features high abrasion resistance, no impact on the substrate material, high adhesion on a wide variety of materials. It is also environmentally friendly and suitable for automatic parts feeding and auto‐matic bolting. The field of application for microGLEIT DF 921 are bulk‐parts, which have to be coated economically for defined fric‐tion values. The coating is used to achieve a defined, predictable frictional behaviour, thus enabling easy and faster assembly. The dry lubricant replaces oil or grease lubrication.

ROCOL revamps ULTRAGUARD SC range

The ROCOL ULTRAGUARD range has long been popular with regular customers as the partner to its range of cutting fluids and has recently undergone a revamp. Using the bactericide cutting fluid additive, ULTRAGUARD BX as a trial, the company changed the pack size from one litre to five litres, upped the dilution to 2,000 to 1, and added a fill indicator, making it easy to see how much is left in a pack. These changes were well received by customers, with the brand being informed that the new pack size is easier to store and the change in dilution means that customers do not need to order the product as regularly, thus making it more cost effective. After the initial one‐year trial, the entire ULTRAGUARD range has now moved over to the new five‐litre pack size, enabling all ULTRAGUARD customers to benefit from the changes, regardless of which product they use.

TIME-SAVING RIVET CARTRIDGES

When it comes to fast and repeatable riviting, Rivit has a cartridge-based offering ready for a multitude of industries, inuding automotive, electronic, furnishing and others…

Rivit Srl is a specialist in the production and distribution of fasteners, fastening systems, tools and machines for sheet metal assembly. Rivit’s Speedriv rivets in cartridges are ideal for quick and repeated riveting and are ideal for light fastenings. They come in a cartridge which can hold 24 to 58 pieces, according to rivet diameter and length, and are strung on a proper rod ready to be used. Rivets in cartridge are available in stainless steel, steel and aluminum, with dome or countersunk head, 3.2, 4.0, 4.8 and 6.0 mm diameters, and in several lengths. Rivets in cartridge provide a dras‐tic time saving during assembling, says Rivit. Speedrivs ensure good flexibility in processes and can be easily included in automatic assem‐bly lines. Rivets in cartridge are mostly used in automotive, electron‐ics, electro mechanics, furnishing and general light fabrication. The new hydropneumatic tool RIV300, featuring a built‐in booster, was specifically designed for the application of cartridge rivets. Depending on the diameter of the rivet, the RIV303 is equipped with special spare parts: head, mandrel and relative spring are selected according to the diameter of the rivet.
