Welcome

GDS is a specialist
on the treatment and coating of metal elements

Our production is based on the latest technologies, managed by specialists with many years of experience in this industry. We place particular emphasis on quality control in the production process, which is constantly monitored and optimized.

The company started with the regeneration of printing rollers and the treatment and coating of metal elements, however GDS is still expanding its activity. We make all metal elements used in various industries. We regenerate, repair worn and damaged elements in such a way that they are indistinguishable from new ones.

We did not have to wait long for success, at present the management board and specialized employees are a strong and motivated team that performs orders for the largest companies in Poland.

The technology we use

The “GDS” company specializes in the application of coatings in the spraying process: cold and hot with acetylene oxygen equipment using the latest spray technology.

The coatings we use are characterized by excellent sliding properties, low abrasion, high mechanical strength and chemical resistance.
They can work at high operating temperatures, so they can effectively replace conventional materials, both for reasons of efficiency and for economic reasons.

Spraying technology is used in MACHINE PARTS REGENERATION (i.e. pivots, power hydraulics elements, e.g. plungers, cylinders, piston rods, bodies, bearing seats, slide bearings, sleeves, bearings, transport rollers, heat exchangers, mixers, etc.) and in the regeneration of rollers and work surfaces of rolls for various types of machines from industry:
► Metallurgical industry, ► Paper industry, ► Food industry, ► Shipbuilding industry, ► Automotive industry, ► Construction industry, ► Textile industry, ► Baking and confectionery industry, ► Off-shore ► Plastic and rubber industry ► The printing industry, ► Chemical and pharmaceutical industry, ► The paint industry, ► Water industry

The application of metal coatings by thermal spraying, also known as spray metallization, has been known for almost a hundred years and is constantly developing in terms of device design and applied materials. The method of thermal spraying consists in melting and spraying the coating metal into small particles in a special device – a spraying torch, and then giving them such speed at the exit of the torch that hitting the covered surface has enough energy to attach to it. The source of heat necessary to melt the metal in the form of powder is a gas flame.

One of the most important factors determining the success of spraying is the specific preparation of the surface of the object being sprayed. First clean it of fats and then remove oxides. The purpose of these operations is to develop the surface and expose the clean metallic surface, and the pre-spraying of the bonding layers is used to form metallic bonds with the substrate. There is powder flame spraying: hot and cold.

COLD SPRAYING is used to apply coatings that undergo abrasive, adhesive, erosive, galling and cavitation erosion wear. The coatings are porous, which is used to saturate them with a lubricant to extend the life of the metal element. Low carbon and low alloy steels are sprayed, corrosion resistant steels, nickel alloys, aluminum, copper, bronzes. The objects are pre-heated to approx. 100 ° C, sprayed with a pre-bonding layer of nickel aluminum and subsequent layers of coating material to obtain the required thickness.

HOT SPRAYING is used for components that are required to have high abrasion resistance, heat resistance, corrosion resistance, erosion and impact strength. The coated elements are heated to a temperature of up to 150 ÷ 500 ° C. Powders based on Ni, Co, Ni-Cr alloys are used for hot spraying. Silicon and boron are present in the chemical composition of these powders. During oxidation in a gas flame, these elements form very fine oxide particles that build into the coating and increase its hardness.

Polyurethane coating

Polyurethane is an extremely versatile and effective plastic, having a special place in the large family of rubber plastics. They combine the best combination of physical and chemical properties.

Properties of polyurethanes:

Hardness 35 – 95 ShA
Temperature range from -30 ° C to + 80 ° C
High tensile and crack resistance
Oil and gasoline resistance
High resistance to material aging, weather, light, UV radiation and ozone
Excellent abrasion resistance, high tear strength
It has good damping

A sample list of polyurethane applications is very long, including:

Polyurethane rods and rings
Mats, plates, polyurethane moldings
Nozzles, polyurethane heads
Sanders and sandbox nozzles
Polyurethane cones and hydrocyclone covers
Polyurethane sieves
Polyurethane connectors
Polyurethane fittings
Polyurethane profiles
Screening elements
Car body parts
Elements of belt conveyors
Drive shafts, running wheels, shock absorbers, rollers, pump components
Rotors, stub pipes, tees, bends, distributors

Polyurethanes have a much higher cut resistance than rubber and, depending on the application and the recipe, also show significantly lower abrasion values. Unlike rubber, dirt does not stick to polyurethanes. They are much more resistant to aging than rubber. Polyurethanes are characterized by high deformability and very high flexibility.

Our polyurethane offer includes:

Polyurethane rollers
Polyurethane bushings
Polyurethane sieves
Polyurethane sheets
And other depending on customer needs.
