Surface Finishing Is More Than Just the Final Touch
At Laitila Coating, surface finishing isn’t just the end of the production line; it’s a critical part of the product’s quality, durability, and performance.
With the right coating, we enhance a product’s mechanical, electrical, and visual properties while extending its lifespan. Surface treatment affects conductivity, corrosion resistance, and even installability.
Seamless Integration with the Entire Production Process
Because we handle the entire manufacturing chain from design to surface treatment and assembly, we ensure each step supports the performance of the final coating. The right choices in materials and machining methods unlock the full potential of the selected finish.
Our versatile coating lines allow us to select the ideal process for your product’s size, shape, and material. We specialise in coatings for electrical components and offer both individual surface finishes and custom combinations.
We treat everything from small turned parts to complex 3D components up to 3000 × 1100 × 500 mm in size.
Electrolytic Surface Treatments
Electrolytic coatings offer excellent conductivity, mechanical strength, and corrosion protection. We provide finishes in tin, silver, nickel, nickel-tin, and nickel-chrome. For aluminium, we also offer chromium-free passivations.
We recommend highly conductive nickel or silver plating for telecom connectors with low voltage and current levels. Treatments can be applied via barrel plating (for small parts like turned components) or rack plating (for larger items).
Each process is carefully controlled and tested. For example, with X-ray thickness measurements, adhesion testing, and regular chemical analysis.
Powder Coating
Powder coating provides a durable and protective surface finish with excellent corrosion resistance, ideal for various sheet metal components.
Before coating, each item undergoes thorough pretreatment, including washing and activation. Then, epoxy, polyester, or hybrid powders are electrostatically applied and cured in an oven, forming a smooth, visually appealing, and durable finish.
We achieve the best results when surface treatment requirements are considered already during prototyping, ensuring compatibility between raw materials, chemicals, machining, and coatings.
We powder-coat simple components on an automated line and apply more complex coatings, such as for enclosures, manually. As a specialty, we also offer electrically insulating powder coatings, providing a clean alternative to traditional insulation sleeves in busbar production.
Need More Than a Surface?
We also manufacture busbars, sheet metal parts, and assemblies. When everything is handled by one partner, you gain consistent quality, on-time delivery, and cost-efficiency.
