These cups are well suited for erratically formed parts with polished or painted surfaces.
Excellent for destacking tubular parts, or in the load/unload of hydroforming applications. The angular shape and soft edge of the cup is pliant and easily conforms to many structures. This cup is used in applications where an exact transport and deposit of the part in a repeatable position is essential. The interior rib geometry holds parts securely during the accelerated or decelerated transfer while avoiding the pulling of dents.
METALS APPLICATIONS
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.
PLASTICS APPLICATIONS
BT 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.

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 BT 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.
Stored on an edge, the shape of the vacuum cups is twisting on the surface, as the material is very flexible. The original round form is therefore not easy to achieve again.
Store cups on a clean, flat surface so that the cup is resting in its natural position.
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.
Wash hands. Wear gloves and protective eyewear.
Prepare a solution of 1 part dish soap and 20 parts potable water. Then, spray the surface of the cup. Never use solvents.
Gently wipe cup surfaces with the soap solution until you achieve an acceptable level of cleanliness.
Briefly rinse the cup with clean, potable water.
Thoroughly dry and reinstall or store appropriately.
For long term vacuum cup storage, we recommend our fabric covers. These protect the vacuum cup from damage relating to prolonged exposure to light and humidity. These are available for round cups in 40mm, 50mm, 60mm, 80mm and 100mm diameters. These can be applied to non-Bilsing branded cups.
