Oven-cured & powder coating services
From electrostatic powder coating of metal parts to painting, soft-touch and vacuum metallizing of plastics with preparation tailored to each material, the right coating for the job and quality control before delivery.
Electrostatic powder application and controlled oven curing for steel, iron, galvanised and aluminium parts. Film thickness is tuned to the application for a uniform look and the right mechanical and chemical resistance.
Most of a coating's lifespan comes from preparation. On metal we remove rust, old paint, oil and mill scale and phosphate where needed. On plastic we remove mould-release agents and static charge and activate low-energy polymers like PP and PE.
For makers of electrical cabinets, enclosures, shelving and machine parts and for Bakelite and polyamide components (PA6, PA66, PA46 and 10% / 30% glass-fibre grades) we deliver uniform, repeatable coating at high volume.
Appliance parts are touched, cleaned and moved every day. We coat ABS, PP and PC housings and covers with paint that resists detergents and scratches, and keep the colour identical across parts made from different materials.
Device housings, switches, sockets and control panels must look good and resist fingerprints, alcohol and scuffs. With the right paint and clear coat for ABS and PC/ABS we create a uniform, lasting surface.
Automotive plastics especially PP bumpers won't hold paint without surface activation and the right primer. With full preparation and flexible paint we deliver a finish that resists impact, stone chips and washing.
For plastic housings and parts of medical devices and for cosmetic and hygiene product parts and packaging, we deliver a clean, uniform surface that resists alcohol and cleaning agents with effects such as soft-touch, matte, pearl and chrome.
Vacuum metallizing gives plastic parts a gloss chrome, matte chrome or Fantachrome (tinted chrome) finish. Hydrographics in a range of patterns such as carbon, wood and stone and anodised-look colours in matte or gloss are also available, all sealed with a suitable protective lacquer.
Velvety soft-touch to European standards, metallic and pearl, deep matte, fine texture, hammer tone and colour-shift finishes for products that need to stand out on the shelf.
For high-touch surfaces, transparent parts and metallized parts we apply scratch- and UV-resistant clear coats, a range of lacquers and polycarbonate hard coats that keep surfaces resistant to abrasion, alcohol and cleaning agents.
How to order
All Saro Coating services are ordered and tracked on WhatsApp via our phone number fast and simple, with no need to visit for a quote. High-volume orders are delivered in the shortest time at the best quality.
Send a photo of the part, the material (if known), dimensions, quantity and your RAL code or colour sample.
Our specialist confirms the preparation and coating system, price and lead time; a sample is coated first when needed.
Once approved, bring your parts to the Saro Factory and they enter the prep and coating line.
After quality control and packing, we arrange collection or delivery with you on WhatsApp.
The process
A great finish is made before the first spray. Every step is tuned to the material and to the paint manufacturer's specifications.
We review the material (metal, plastic or Bakelite), size, environment and the colour and effect you want, then choose the right paint and pretreatment; new parts get an adhesion test on a sample.
Metal: degreasing, rust and paint removal, sandblasting and, where needed, phosphating. Plastic: washing, removal of mould-release agents, anti-static treatment, flame or plasma activation and an adhesion primer.
Metal parts are powder coated with electrostatic guns; plastic parts are sprayed with plastic-specific paints in a clean, dust-free booth evenly, with no runs or brush marks.
Each part is cured for the right time at a temperature matched to its material from 60 to 200 °C so the coating fully cures and reaches final hardness without warping.
Every layer's thickness is measured, and adhesion (cross-cut test), colour uniformity, gloss and the match to the approved sample are inspected before release.
Once cooled, parts are packed with protective wrapping so they arrive without a scratch.

Materials & coating types
The right coating depends on the part's material and where it will be used. We'll recommend the best option during consultation.
Very smooth finish with good abrasion and chemical resistance.
Excellent adhesion, chemical and corrosion resistance; chalks under prolonged sunlight.
High UV and weather resistance with good colour and gloss retention.
Great decorative appearance at a good price for indoor environments.
Low surface energy: without activation and a dedicated primer, paint peels. Flame or plasma treatment plus a polyolefin primer gives full adhesion.
One of the hardest plastics to paint; coated only after careful surface activation, a dedicated primer and an adhesion test on a sample.
PA6, PA66 and PA46, unfilled or glass-fibre-reinforced (10% and 30%). Absorbs moisture and must be dried before painting; on glass-filled grades the paint system is chosen so fibres don't show through.
The most paintable engineering plastic with excellent adhesion first choice for decorative parts, device housings and vacuum metallizing.
Impact-resistant and sometimes transparent, but sensitive to solvents and stress cracking; painted with compatible paints and scratch-resistant hard coats.
A heat-resistant, electrically insulating thermoset; takes paint well after cleaning and light sanding.

Ordering FAQ
Orders are placed on WhatsApp using Saro Coating's phone number. Send a photo, material, dimensions, quantity and colour and we'll reply with price and lead time.
A clear photo, approximate dimensions, material (on plastics it's usually moulded in, e.g. >PP< or >ABS<), quantity, surface condition (old paint or rust) and your RAL code or colour sample.
No problem. We inspect the part and run an adhesion test on a sample to choose the right preparation and coating system.
Yes. On metal, the old coating is fully removed by stripping or sandblasting; on plastic, depending on the old finish, the surface is sanded or the old paint removed so the new coat bonds fully.
RAL colours are the most readily available. Custom colours and effects can be sourced; we'll confirm lead time when you order.
