Painting plants

The painting lines operating at Tecna Plast are the result of solid planning and targeted investment over time. Thanks to anthropomorphic industrial robots and automatic mixing machines, it is possible to provide high quality coatings, both from a purely aesthetic point of view and in terms of process parameters. While automation ensures efficiency and repeatability, the company is aware of the limitations and challenges of the industry, which is why we are constantly striving for continuous improvement to deliver results that meet the ever-increasing demands of our customers.

Solutions

Tecna Plast is equipped with two completely independent painting lines, one manual and one fully automatic.

​

MANUAL LINE

​It is a plant capable of processing small batches and enables the development of new painting cycles and pre-series sampling. The application booth and drying oven are confined within a single environment, thus guaranteeing a pressurised environment, free of pollutants that could affect the quality of the finished product.

AUTOMATIC LINE

The main painting line is equipped with automatic mixing machines and anthropomorphic robots capable of guaranteeing constant and uniform thickness, paint spreading, gloss and colour coordinates from the first to the last piece of the production batch. These state-of-the-art systems for industrial painting also allow great speed of execution, economies of scale and competitiveness, results that cannot be achieved by manual processing. The rooms are fully pressurised, with real time temperature control and constant maintenance of optimum processing conditions for paint products, with airflow control and state-of-the-art filtration systems.

The thermal curing oven guarantees dwell times between 30 and 120 minutes at temperatures between 75°C and 90°C. This versatility makes it possible to optimise this phase of the painting process, one of the most important as it is the one that gives to the film its final hardness and resistance.

All our equipment and accompanying systems have technologically advanced features tailored to our needs and those of the customer.

The following is a summary of some of the technological features Tecna Plast is equipped with.

Controlled environments

The processing environments are constantly monitored with accurate pressurisation and constant climate control, guaranteeing optimal application conditions for all types of paint products currently on the market and requested by customers. In fact, advanced systems are in use to precisely control air flows and limit contamination by external agents as far as possible.

Management of paint products in application

The products used at Tecna Plast are of several types because customers' requirements are quite different depending on the component to be coated. Each paint must therefore be managed differently by adopting different pumping, stirring, and dispensing systems.

Tecna Plast has different pumping technologies ranging from the typical system consisting of lowpressure diaphragm pumps to more complex systems consisting of constantly pressurised tanks. Almost all paint products need to be constantly subject to gentle agitation to maintain constant viscosity. Over the years, Tecna Plast has developed a system to keep this process under control by intervening directly on the agitation system to avoid significant variations in viscosity during production, which would compromise the painting process.

Cleaning system

A fully automatic cleaning system is being installed by means of ionising air blowing, able to remove any pollutant residue on the surface with high efficiency, guaranteeing a completely inert substrate ideal for painting and a high-quality finished product.

 

The system will also be prepared for the installation of a CO2 cleaning system, a system whose feasibility study for its installation in the short term is underway.

Mixture preparation room

The preparation room is equipped with an automatic paint mixing system to ensure a high degree of consistency in the intrinsic characteristics of the paint products prior to application, which is essential to achieve high quality standards.

Curing oven

Our curing ovens ensure optimal curing times and real-time temperature control.

The installation of a UV curing system is currently being evaluated to meet the daily demands of the automotive sector, offering both Mono-Cure and Dual-Cure processes that are indispensable in solving the ongoing challenge of scratch resistance.

Industry 4.0

The recently implemented management system allows plant personnel to constantly monitor all process parameters in real time. This allows the staff to keep the entire process under constant control, enabling high quality to be achieved.

An optimising Industry 4.0 system will allow for a completely state-of-the-art management of all company phases in terms of both process and planning and logistics.

PLASTIC components

Plastic is a widely used material in different industries, but by its nature it does not have a high degree of resistance to the environment in which it is set to be used. Varnishing plastics is therefore essential to guarantee them a high degree of resistance, as well as to provide surface aesthetic effects that capture both touch and sight. The main plastics currently processed by Tecna Plast are ABS, PA, PU, PP and PC.

METAL    components

In the automotive sector, but not only that, it is very often necessary to protect metal components from corrosion-related phenomena. In addition to ensuring a high degree of protection, painting can also generate a pleasant aesthetic effect. In this case, painting requires special attention to the preparation of the substrate to ensure a high degree of adhesion and a consequently high durability of the treatment.

Services

Following the actual painting process, Tecna Plast can give further functional and/or aesthetic value to the painted components through a series of aesthetic processes, with those it is possible to engrave graphic symbols, such as ideograms typical of the automotive world or fully customisable logos and trademarks. Over the years, Tecna Plast has gained experience in laser marking and pad printing processes, guaranteeing compliance with the standards currently in force.
