Gas springs are used in many sectors: from automotive to metalworking, from medical to food, and even in the nautical world. They have also been introduced in the field of furniture design, and in all cases, Vapsint is a reference point for their production. Vapsint was founded in the 1960s as a specialized workshop for the production of regenerated shock absorbers for vehicles and the marketing of auto spare parts. The company has experienced continuous expansion, and in the 1980s, the production processes were industrialized, allowing for faster and improved activities, as well as the development of new products. Currently, Vapsint produces both free-stroke gas springs and gas springs with a locking system. All springs are supplied in the standard matte black color and can also be made in other colors upon request. Each spring is composed of a steel cylinder containing pressurized nitrogen and a rod that slides within the cylinder through a seal ring. The gas compresses when the rod enters and returns a push, acting like a spring. Compared to traditional mechanical springs, gas springs have a nearly flat force curve even for long strokes. They are therefore used in cases where a proportional push is required for lifting or moving weights, or to counterbalance the lifting of heavy and mobile equipment. In the furniture industry, they are particularly useful for constructing doors in any type of furniture.
Vapsint produces various types of gas springs for furniture, capable of satisfying all the needs for the movement (opening/closing) of doors and lids. The current range consists of Rapid Fit, standard gas springs; Fix-It, standard gas springs with adjustable attachment; Free Stop and Neutro Free Stop, friction gas springs that allow the door to be opened and stopped in any position; Dampers, hydraulic springs ideal for damping the fall of doors with tilt opening. For the furniture sector, the company has designed a specific attachment, defined by the acronym TSNS, which is screwed onto the two ends of the spring, making installation and removal easier. Vapsint also manufactures brackets, which are the elements necessary for connecting the gas spring to the furniture. Going into more detail, we would like to point out that the Rapid Fit gas spring stands out for its rapid assembly attachment, developed by Vapsint for the first time in 1995; thanks to the articulated movement, it proves to be ideal for all door inclinations. The Fix-It gas spring with adjustable attachment is available with various strokes and forces, allowing for the management of different heights and weights of wooden, aluminum, and aluminum glass doors. The Free Stop spring is the same in composition as a standard gas spring but differs from it in terms of the piston, specifically designed to ensure a frictional outward and inward movement of the stem. The Neutro Free Stop spring is characterized by a special extension of the body that is applied to a Rapid Fit gas spring to provide an additional frictional stroke; it is used in tall wall units to prevent the door from lifting up in an unreachable position. The Dampers hydraulic spring is composed of a steel cylinder inside which a rectified and chromed rod slides, communicating with the outside through a sealed guide that ensures the seal of the oil. Attachments are applied to the ends of the body and the rod to allow for fastening. Vapsint has also patented Softload, a lifting mechanism particularly suitable for applications that require the use of non-standard sized and/or particularly heavy doors. In these cases, the use of traditional gas springs would tend to exert all forces on the door's fixing hinges, damaging them. Softload, instead, thanks to its particular geometry, diverts these forces to the side fixing plates.
