Summer holidays: 12th till 24th August

23 July 2018. A magical sunset from our beautiful Venice that invites to relax to wish that your summer holidays will be dedicated to relaxing as well as enjoying. We want to inform you that our office will remain closed from 12th till  24th August. We’ll see you on 27th August.

A brand-new plant in Germany can be visited upon request

23 July 2018. We are here with a new reference for our Fastrip 1250 technology. The paint-stripping machine for in-line paint stripping, with a filter-press, has been installed and functioning at one of our clients’ plants in Germany. Unfortunately, we are not authorized to name this industrial partner. However, if you wish to get more information regarding this or visit the plant to have a look at the working of the machine, just let us know.

ALIT’s new product range Fastrip presented at PaintExpo 2018

At the leading trade fair for coating technology PaintExpo 2018, ALIT presented Fastrip, a new range of innovative paint stripping machines.

ALIT has developed Fastrip, a range of innovative paint stripping systems suitable for the different needs of each company.

The Fastrip system range, which was presented for the first time at PaintExpo 2018, includes in-line paint stripping systems, immersion paint removal tanks, and spray systems, with different sizes and equally different investment costs.

The Fastrip T5 system

This off-line stripping system for hooks, frames, and parts to be restored features a medium-sized tank with a capacity of about 600 litres of chemical product. The process enables to remove the paint on hooks and components without attacking the base metal.

The Fastrip T5 system is available in three versions combining a chemical and a mechanical action:

  • T5-U with ultrasound technology;
  • T5-A with an air agitation system;
  • T5-M with a mixer.

The Fastrip S system

In order to meet the needs of the numerous companies that clean and coat their machined components in-house, ALIT has developed Fastrip S, a vertical spray stripping system that allows to create a paint removal station with a small footprint, adjacent to the industrial cleaning plants.

Fastrip S consists of a paint stripping station and a rinsing tank.

ALIT Introduces Fastrip and Fastrip MT

With Fastrip and Fastrip MT, ALIT brings innovation in inline paint stripping of hooks and the recovery of aluminium profiles.

The Fastrip system

A hook in a modern painting plant, after several passes in the paint booth, can reach thicknesses of polymerised paint of 100 – 120 micron. These thicknesses prevent the necessary conductivity for electrostatic application, resulting in the negative effects of oversprayand an incorrect application of the powder on the product, which can amplify the “orange peel” effect of the film. 

The Fastrip system consists of a tank containing the stripping product positioned between the unloading and loading area of the plant. Just by extending a section of the pre-existing conveyor, the hook, in its travel from the unloading station towards the loading station and without being released from the chain, can be submerged into the tank (sized so that it maintains contact with the stripping solution) for approximately three minutes.

While the hook slides through the solution, the paint is stripped. At the end of the process, the conveyor repositions the hook in the correct loading area, where the profiles are ready to be painted. This stripping system avoids the continuous removal of the hooks and, as a result, loss of time by operators and allows for a reduction of powder coatings consumption. 

To allow the operators to have a very simple process to manage without downtime for cleaning the tank, the system is fitted with a system for the filtration of paint sludge deposited on the bottom.

The Fastrip MT system

Besides hook cleaning, recovering profiles with painting defects is very important. Normally, the profiles to be recovered were sent to outside companies specialised in paint stripping, but during the economic downturn, many companies tried to set up in-house processes to perform this step. Based on ALIT’s experience with stripping paint from hooks, the company developed stripping systems for other processes. This is where the idea came up to offer a solution for stripping paint from aluminium profiles, which ALIT named Fastrip MT (Multi Tank). 

The conceptconsists of designing a modular plant including different tanks served by an automated overhead crane.

“Stripping the aluminium profile in the most complete version of the systems requires a stripping tank, a heated tank with automatic cover, a second tank for rinsing, a third tank for alkaline pickling at a temperature of 30- 40 C°, a fourth 

tank for rinsing, a fifth for neutralization and a sixth for rinsing. Tanks are designed to allow the paint sludge to be conveyed to the filtration system fitted with a filter press and decanting vat. The filtered solution is then sent to the

stripping tanks. This is the ideal configuration of the Fastrip MT plant; however, options exist to reduce the number of steps by installing first a stripping tank followed by a rinsing tank. This enables companies to reduce their initial investment while maintaining the possibility to expand the stages of the process later, using the same platform and inserting the overhead crane and the filtration system to obtain savings in the stripping product and management costs”, explains ALIT’s CEO Loris Rossi to ipcm® International Paint&Coating Magazine. 

Fastrip MT has been designed to solve the problems of aesthetic finishing that arise during the final stage in the process of painting aluminium profiles; it avoids having to scrap material that has been painted badly, having to sand it down or wasting precious time by having outside companies perform chemical stripping.

Fastrip ISP installed at Sepal

Aluminium profile manufacturer Sepal Spa has installed a Fastrip ISP inline system for the stripping of its hooks. 

Sepal’s plant in Lograto (Brescia, Italy) has been equipped with the Fastrip ISP hook stripper, which eliminates the need to remove the hooks from the conveyor and send them to a stripping contractor.

The system consists of a tank for the paint stripping product positioned between the unloading and loading stations. On their way from one station to another, the hooks are immersed in the stripping tank while still hanging on the chain.

After about 3 minutes, they are cleaned from any paint accumulation that can affect electrostatic generation during application.

ALIT Technologies: the new Alufinish Italia brand dedicated to chemical paint stripping and much more

Alufinish Italia has set up a new brand, ALIT Technologies, which will develop products and processes for the chemical paint stripping technology, among others.

Starting from January 2016, the inline paint stripping processes market will be covered by ALIT Technologies.

Therefore, the Fastrip ISP process and all Metalstrip products, previously marketed by Alufinish Italia, will be now supplied by Alit Technologies. 

Fastrip ISP is an inline chemical stripping process that combines the efficiency of a dipping line featuring a particular ultrasonic technology specifically developed for this system with a chemical product of the Metalstrip range, able to remove any coating from hooks and frames in only two minutes. 

The Metalstrip paint stripping products contain no chlorine compounds and are environment-friendly, and their formulation allows for their use with this new stripping system. They are suitable for frames made of ferrous material, aluminium or other light alloys.
