Contact Plating

In-house application of contact plating to optimise costs

Operating since 1965 in the connectics industry, Lemco Précision is an expert in the production of high-precision electrical contacts, from standard to more complex shapes, bent parts (double angles such as "S-shaped") or miniature contacts.


Since we understand that the optimization of production times and costs requires complete control of the production line, we carry out in-house, every step of manufacturing your contacts, including the plating of electrical contacts.


Our coatings capabilities include the following treatments:
Silver-plated contacts, selective gold plating, gold-palladium plating. Striving to provide you with the best products in terms of technology and finishing, we own a subsidiary dedicated to plating and particularly specialized in galvanoplasty, nickel plating, copper, and gold plating.


We are thus able to meet all your needs and adapt our products upon request. Thanks to our constant quest for innovation, we have developed other surface treatments such as Swisscoat, allowing your parts to be protected with less gold and identical performance to much thicker coatings.

Expert in surface treatment of electrical contacts

Thanks to over 50 years of experience in screw machining contacts, in particular working with complex, long and small-diameter contacts as well as miniature sizes, we are also experts in the surface treatment of contacts, regardless of their geometry or fragility.

Key Facts

Our technology offers several advantages

Defect-free gold plating

We have been applying gold plating to our contacts for over 40 years in our production plants, and we are experts in handling fragile, fine, and small-diameter parts.

Guaranteed cost optimization

By performing the plating ourselves, we optimise both costs as well as production times and performance, whilst ensuring a high-quality finish.

Innovation for reliable and high-performance contacts

We have developed innovative solutions to manufacture contacts with ever-increasing performance. By improving our plating processes, we created Swisscoat and continue to innovate.

100%

of our contact surface treatments is performed in our production sites to ensure the best quality

Heat treatments to optimise the resistance of your parts

In addition to applying coatings, we also perform heat treatments. This is executed in our own workshops and improves contact resistance to all types of environments encountered throughout their life cycle. We also perform sand blasting to obtain the cleanest and smoothest parts possible.
