Painting of plastics

Industrial plastic painting requires precise control of parameters such as flow rate, atomization, and spray fan, in order to guarantee a uniform finish on very different materials and geometries. Lesta builds automation for the spray painting of industrial plastic components, finding wide application across several sectors.

One of the main sectors for plastic painting is automotive, where quality and quantity standards are constantly subject to very strict checks — precisely why our customers have chosen Lesta as their partner. Typically, in a painting plant for plastic parts, we propose the Lesta RECIPE MANAGER accessory. This system acts on the painting parameters of guns and reciprocators and allows management of flow rate, atomization, fan, opening delay and advance, and cycle time. Lesta RECIPE MANAGER organizes parameters into easily recallable recipes.

Lesta’s self-learning painting robots are widely used for finishing and flame treatment of plastic components, composite polymers and rubber, in the painting of bumpers, hoods, helmets, fashion accessories, buttons, casings, tractor covers, toys and much more.

The Lesta RECIPE MANAGER system for industrial plastic painting

For industrial plastic painting, Lesta provides the Lesta RECIPE MANAGER software, which organizes all painting parameters — flow rate, atomization, fan, opening delay and advance — collecting them into recipes that can be recalled at any time. This means that, when changing the component to be painted, it is enough to recall the corresponding recipe instead of manually reprogramming every parameter, reducing setup times and operational errors. This approach is particularly useful for companies working on order or with small batches, where product changeovers are frequent.

Sectors and components for industrial plastic painting

The automotive sector represents one of the most demanding areas for industrial plastic painting, due to the high quality standards required on components such as bumpers, hoods and helmets. The same technologies are also applied to different sectors: fashion accessories, buttons, casings, tractor covers, toys and many other products in plastic, composite polymers and rubber. In addition to painting, Lesta’s self-learning robots are also used for flame treatment of plastic components, a surface treatment that improves paint adhesion before application.

Why automate industrial plastic painting

Plastic is a material particularly sensitive to variations in application: an excessive amount of paint can cause runs or longer drying times, while insufficient coverage compromises the appearance and durability of the component. By automating the process, the painting path and parameters are recorded only once and faithfully reproduced on every subsequent piece, guaranteeing consistent quality regardless of production volumes. Like all Lesta solutions, these plants are designed and manufactured entirely in Italy.
