Molding and electroplating under contract
We implement your projects and follow you during each phase
guaranteeing maximum quality:
Marvon has over 50 years of experience in galvanic chrome plating on plastics.
The first treatments date back to 1968; since then the company has constantly innovated, updated and improved its processes and production facilities to offer the market the cutting edge of the technical solution. That is why today Marvon is one of the reference galvanic in Europe for the chrome plating of plastics in different sectors and fields of application.
The management’s strong commitment to production excellence, combined with the requirements of an increasingly demanding market gave a boost to the optimization of the production process, which, over recent years, has been completely automated and enhanced with the introduction of software that allows for maximum production flexibility and the utmost severity in the respect for specifications.
The items we process are subjected to strict processing parameters detailed in specific technical data sheets that meet the customer's needs.
At the end of each production cycle, accurate quality controls are carried out to ensure that each galvanized piece lives up to the expectations of the end customer.

Laser engraving
The last highlight of the services offered by Marvon is the lasering on previously galvanized pieces
How the incision works:
Laser engraving has many advantages over the traditional technique. To make it possible the material is heated from the laser that, depending on frequency, power and speed parameters, changes colour creating a contrast on material’s surface. The engraving thus obtained is long-lasting and resistant to abrasion. Laser technology makes it possible to create extremely defined and refined decorative elements with the utmost precision. It has an incredible definition of detail and can reproduce everything we can draw. We can then go to create and reproduce all the writings or logos on any surface, the contrast obtained varies depending on the basic material. This gives us the possibility to customize the galvanized pieces of any finish, the plastic and stainless steel materials, and all the accessories of the technical furniture sector.
A fundamental feature is respect for the environment. Laser marking is carried out without the use of polluting products with the possibility of further customizing the workpiece with the logo desired by the customer.
Brushing (Stainless steel effect)
We have decided to expand the range of finishes offered with further processing that allows us to give the items a stainless steel-like appearance.
First of all, the plastic molded pieces must be subjected to galvanic processing double polished nickel, this will allow them to be mechanically brushed.
The effect obtained means that the pieces can be used in many fields of application: from accessories for kitchens (knobs, grab rails) to those intended for high quality bathroom and shower furniture.
Quality without compromise
Marvon has a fully equipped laboratory for the most scrupulous quality controls in terms of the inspection of incoming raw materials, the parameters of the electroplating baths and the wastewaters. During the production process tests with saline mist are also performed, the verification of the thickness of the deposits with the possibility of performing crash tests.
Particular attention is paid to the environmental impact and the environmental management system was certified in compliance with UNI EN ISO 14001.

FAQ
Frequent questions
What type of material do you chrome?
The plastic materials that we treat with electroplating (chrome, gold and nickel plating) are: NEUTRAL ABS FOR CHROMING, THERMOSET (PHENOLIC RESINS) - BAYBLEND (MIX OF POLYCARBONATE AND ABS) WITH A MAXIMUM PERCENTAGE OF POLYCARBONATE OF 45%.
Do you chrome nylon?
No, we do not chrome nylon.
Do you chrome zamak or other metals?
No, our plant is structured for the processing of plastic materials only.
To commission a job do I have to create the equipment?
Yes, to obtain the best result in terms of quality and production it is essential to have specialized equipment.
What is the percentage of waste?
It is the physiological value of the electroplating process determined by the complexity of the production process and the compliance with the high quality standards that you request and we guarantee.
Do I have to observe a minimum batch?
Yes, and it corresponds with a number of pieces that make up a bar. This is to guarantee the uniform distribution of power to all of the pieces and ensure the maximum possible level of quality.
From when I send the rough material, when can I expect delivery?
The start of production depends on two factors: the degree of saturation of the production capacity when the material is sent and the production program; in general processing starts no later than 72 hours from receipt of the material and delivery depends on the batch sent for processing.
Is it true that there is a European standard that provides for the elimination of hexavalent chromium?
NO, there is no European regulation that imposes the replacement of chromium VI. The regulation CE N. 1907/2006 (REACH) does not impose replacement of CHROME VI, but provides for the authorization for its use as of 21 September 2017.
In this regard, we remind you that chromium VI is present inside decorative chroming and etching baths, but is not present on parts supplied to clients in that a layer of chromium metal (CHROME 0) is deposited on the parts and is completely INERT.
Galvanic process: step by step explanation
The company has a chemical pretreatment line and an electrolytic line. The moulded pieces are placed on special frames and subjected to treatments aimed at obtaining the metallization of the piece, by subsequent immersion in adjacent tanks.
- Assembly: the operators place the articles on the dedicated frames, making sure that the grip of the same is optimal and firmly;
- Etching: this treatment, carried out using a sulphur-chromic mixture, is used to oxidize the butadiene present on the surface of the material and create surface microporosities, necessary for the subsequent phases;
- Neutralization: this phase involves the immersion of the pieces in a strongly reducing solution: this allows the complete reduction of the Cr6+ possibly residual to Cr3+, and is carried out to avoid interference with subsequent treatments;
- Pre-catalysis: this phase consists instead in the immersion of the frames in a solution of the same acid / saline base of the catalysis bath, in order to avoid the possible dragging of Cr6+, but above all to avoid any dilutions of the solution present in the next tank;
- Catalysis: the pieces are at this point immersed in a tank containing the colloid Palladium – Tin Chloride: this colloid is adsorbed in the microporosities obtained from the previous phases: this operation is carried out in an aqueous solution of HCl or NaCl, saturated in Sn2+ and SnCl2 ions, in order to avoid the hydrolysis of the Sn
- Acceleration:it is effected by means of an aqueous solution of Sulfuric Acid and additives, in order to solubilize the colloid and remove from the surface of the piece all the elements not made up of noble metal (Pd);
- Metallization with chemical nickel: catalysis and acceleration operations are necessary for the deposition of nickel on the plastic material; nickel is chemically deposited, forming chemical bonds with palladium. This phase is necessary to give conductivity to the plastic piece and thus make possible the subsequent phases of electrolytic deposition;
- Electrolytic coppering: an electrolytic deposition of copper is carried out on the treated piece;
- Electrolytic nickel plating, chrome plating or gold plating: the electrolytic coppering phase is followed by the nickel plating phase which, depending on the customers' requests, can constitute the final galvanic treatment or can be followed by chrome plating or gold plating. Nickel plating, chrome plating and gold plating are also carried out by electrolytic deposition.
- Washing: after each step (except for the steps of pre-catalysis and catalysis) the washing of the pieces is carried out.
- Packaging: at the end of the chrome plating process, the items are placed inside the dedicated packaging to best preserve the specifications requested by the customer.

Laseratura
Ultimo fiore all’occhiello dei servizi offerti da Marvon è la laseratura sui pezzi precedentemente galvanizzati
Come avviene l’incisione:
L’incisione con tecnica laser presenta numerosi vantaggi rispetto alle soluzioni tradizionali. Per poterla eseguire il materiale viene riscaldato in maniera significativa dal raggio laser che, a seconda dei parametri di frequenza, potenza e velocità, cambia colore creando un contrasto sulla superficie del materiale. L’incisione così ottenuta è duratura nel tempo e resistente all’abrasione. La tecnologia laser consente di realizzare con la massima precisione elementi decorativi estremamente definiti e ricercati. Ha una definizione di dettaglio incredibile e può riprodurre tutto ciò che siamo in grado di disegnare. Possiamo quindi replicare testi e loghi su qualsiasi superficie, con un contrasto variabile a seconda del materiale di base. Questo ci dà la possibilità di personalizzare i pezzi galvanizzati di qualsiasi finitura, le materie plastiche ed inox, e tutti gli accessori del settore arredamento tecnico.
Caratteristica fondamentale dell’operato di Marvon è il rispetto dell’ambiente. La marcatura Laser viene effettuata senza l’utilizzo di prodotti inquinanti con la possibilità di personalizzare ulteriormente il pezzo lavorato con il logo desiderato dal cliente.
Spazzolatura (effetto INOX)
Abbiamo deciso di ampliare la gamma delle finiture offerte con un'ulteriore lavorazione che permette di conferire agli articoli un aspetto simil-inox.
Innanzitutto, i pezzi stampati in plastica devono essere sottoposti alla lavorazione galvanica doppio nichel lucido, permettendone la spazzolatura meccanica.
L’effetto ottenuto fa sì che i pezzi possano essere utilizzati in molteplici campi di applicazione: dagli accessori per le cucine (manopole, maniglioni) a quelli destinati all’arredo bagno box doccia di alta qualità.
Qualità senza compromessi
Marvon dispone di un attrezzato laboratorio per i più scrupolosi controlli qualitativi in termini di controllo in ingresso di materie prime, parametri dei bagni galvanici e sulle acque di scarico. Durante il processo produttivo vengono inoltre eseguiti anche test in nebbia salina, controlli sugli spessori dei depositi con possibilità di effettuare crash test.
Con una particolare attenzione all’impatto ambientale, ha certificato il proprio sistema di gestione ambientale in accordo con la norma UNI EN ISO 14001.
