Our silicone-free PFG vacuum cups offer maximum flexibility in adapting to shaped components.
Our silicone-free PFG vacuum cups, designed in geometries for high speed applications, offer maximum flexibility in adapting to shaped components due to a very soft lip and rigid core. They feature an oil displacement lip on the outer edge, and the arrangement of the brake ribs ensures that oil and dirt are properly extracted. With a one-part body design they are easy to exchange. Additionally, this feature means less damage to metal sheets compared to other designs. With more wear-resistance and longer service life than an NBR cup, after 4,000,000 strokes the cup shows hardly any signs of wear.
Servo-press machines and the newest automation technologies have accelerated production processes in press shops.
Higher manipulation speed as a result of this upgrade demands vacuum cups with higher adhesion and friction forces as well as more flexibility.
PFG cups are complimentary for plastic applications, such as demolding bumpers in the plastics industries as they are PWIS free.
PWIS stands for Paint Wetting Impairment Substances. The terms covers all problems encountered in the coating of surfaces. On almost all products, whether recently manufactured or from storage, there are – usually invisible – deposits which prevent coats from adhering: greases, oils, silicones, moisture, oxidation layers. By means of plasma cleaning , these deposits can be removed to make surfaces PWIS-free. To check the surfaces after cleaning and before painting.
The PFG cups are designed specifically for high-speed applications and can adapt to various part geometries, handling steel, aluminum and plastic materials. These cups are suited for continuous use at temperatures up to 100°C and for short-term use up to 125°C. There work with connection adapters in various designs made of aluminum and steel, in either pin or ball connections.
Proper care and storage of your vacuum cups can dramatically improve their performance and life. If you have questions regarding how to best care for, maintain and store your cups, please reach out to your local Bilsing Automation representative to discuss your unique needs.
When storing, all PFG cups should be laid cup side vs. mount side down, otherwise the shape of the cups can be distorted. For packaging, all materials use in covering and wrapping must be free of substances that degrade elastomers. Appropriate packaging materials include PE-coated craft paper, aluminum foil or opaque PE foil, at least 0.075mm thick. The control temperature must be below 25°C and should not be exposed to direct sunlight – the best storage condition for our cups is in dark surroundings. Additionally, the humidity should be kept so that no condensation appears during temperature changes. In these conditions, the cups can be used for up to five years. If these conditions are deviated from, the cups may only last two to three years.
Routinely check cups for wear or damage and cleanliness. If you find the cup needs cleaning, wear protective eyewear and gloves, then wipe the cups with a solution of mild dish soap and warm water. Never apply solvents, such as disc brake cleaner as it will destroy the cup.
