Hot air Welding

Hot air welding is a versatile technique for joining thermoplastic materials. Using a hot air welder, plastic parts are heated and joined, after which material is added, thereby creating a tight weld. This method is popular for its versatility and ability to create strong and durable joints and is often used for smaller items or tacking.

Application

Hot air welding is used in many industries. At Plast Solutions, the method is most commonly used for the repair and manufacture of plastic components. It is also effective in the production of tanks and piping systems that require watertight connections or tacking before other welding processes.

Advantages

This method is cost-effective, requires minimal equipment, and is ideal for both large projects and smaller repairs. Its portability also makes it practical for on-site work.

Extruder Welding

Extruder welding, a powerful technique for welding larger plastic components, is ideal for more extensive industrial projects. This method involves a plastic extruder, which is a specialized tool that heats plastic granules or welding wire into a molten mass. This melted plastic is then extruded through a nozzle. During the welding process, the molten plastic is applied along the joint of the two plastic components that need to be connected. som er et specialiseret værktøj, der opvarmer plastgranulat eller svejsetråd til en smeltet masse. Denne smeltede plast udskilles derefter gennem en dyse. Under svejseprocessen påføres den smeltede plast langs samlingen af de to plastkomponenter, der skal forbindes.

Application

Extruder welding is particularly useful in industries where large plastic constructions are the norm. This includes the manufacturing of large plastic containers such as tanks and wells, piping systems, and construction elements in industrial facilities. It is also popular for constructing water and wastewater systems.

Advantages

The primary advantage of extruder welding is its ability to handle large and complex welding tasks, making it a preferred method for projects that require strong, complex, and durable joints. This technique is also effective in ensuring a uniform and homogenous joining of the materials, which is crucial for the long-term integrity of the welded product.

Electrofusion Welding

Electrofusion welding, also known as electrofusion welding, is a specialized technique for connecting plastic components, especially in piping systems. This method uses electric heating elements embedded in fittings, which melt the plastic and create a strong, homogeneous weld.

Application

Electrofusion welding is ideal for piping systems in aquaculture facilities, water supply, wastewater management, and gas distribution. The technique is used to connect pipes of different diameters and is particularly suitable for installations where precision and tightness are critical. It is also a preferred method in situations where pipelines need to be repaired or expanded.

Advantages

The advantage of socket welding is its ability to create extremely strong and tight welds, which is vital for infrastructure that transports fluids or gases under pressure.
Here, the pipe's original pressure class is preserved.

BUTT Welding

Butt welding is a widely used method for industrial plastic processing, especially for pipe welding of lengths and bends of all degrees. This technique involves heating the ends of two plastic parts, typically pipes, against a heated mirror and then pressing them together to create a strong and uniform weld.

Application

Butt welding is widely used in the construction of pipe systems for water, gas and chemical transport. This method is particularly valuable in industrial construction projects where durability and tightness are important. Butt welding is also a preferred technique when installing pipes underground, as it ensures a long-lasting and leak-free joint.

Advantages

The primary advantage of butt welding is its ability to create extremely strong and durable welds. This method is relatively simple and can be automated, increasing efficiency and reducing the margin of error. Butt welding is also known for its versatility, as it can be used on a wide range of plastic types and pipe dimensions.
The pressure class of the pipe is maintained.

Sheet butt Welding

Sheet butt welding

Sheet butt is a technique for the exact shaping of sheet materials that requires high and detailed precision. This method uses advanced tools and techniques to create specially designed shapes and components from different sheet materials.

Application

In industry, plasterboard is primarily used for the special production of tanks and wells, adapted to specific purposes and dimensions. This technique is particularly important in the manufacture of custom solutions where standard sizes and shapes are not sufficient. Sheet butt enables precise design of complex constructions, which is essential in projects that require special sizes.

Advantages

The main advantage of the sheet butt technique lies in its ability to create customized, robust structures with high accuracy. The technique is ideal for situations where a combination of strength, durability and precision tolerances are required. This approach ensures that the finished tanks and wells are not only functional, but also meet the highest standards of quality and performance, which is essential in demanding industrial environments.

Segment Welding

Segment welding
Segment welding is a technique for welding together plastic components with degree bends as needed. Using precision welding equipment, this method can ensure strong, accurate welds when making bends in engineering piping systems.

Application
Segment welding is used to manufacture complex pipe systems,
This method is particularly valuable in industrial construction projects where durability and tightness are important. Segment welding is also a preferred method when installing pipes, for e.g. manifolds and technical piping, which ensures a long-lasting, leak-free assembly.

Advantages
The technique's flexibility to form desired degree bends and its ability to create durable, precise connections make it ideal for complex industrial applications.
Segment welding is an optimal solution in connection with lack of space or obscene angles, resulting in consistently high quality and reliability in the joints.

Socket fusion Welding

Socket fusion welding
Socket fusion welding is a technique that uses a cylindrical mandrel to expand the pipe ends, after which heat is applied to melt and join them. This method is unique as it combines mechanical expansion and thermal fusion, ensuring a precise and homogeneous connection of plastic components.

Application
The technique is often used to apply smaller studs to larger items such as sensors, manometers or the like. In addition to this, socket is also a recognized solution for welding pipes together. These are welded together with so-called socket mandrel fittings. This solution is used, among other things, in the pharmaceutical industry.

Advantages
Socket fusion welding ensures an accurate and tight joining of plastic parts, which is important in environments where tightness and long-term durability are required. This method is particularly effective compared to conventional welding methods, as it reduces the risk of leaks and ensures a higher degree of uniformity and reliability in the welds.
