PRECI-DIP has won international acclaim for its indigenous manufacturing methodologies to produce cutting-edge interconnect components.  PRECI-DIP is of one the leading suppliers of screw-machined contacts for Defence and Aviation industry, Engineering, Electronics industries, ICT and many more.

Incorporation of advanced designs, use of finest materials and the inimitable Swiss precision has always been the elements of manufacturing interest at PRECI-DIP. The manufacturing of precision tools and contact assembly machines is supported by PRECI-DIP’s state-of-the-art CAD systems and 3D projections. PRECI-DIP has superior control over the manufacturing processes which are perfectly integrated in line with vertical production structure. It is the concreteness for maintaining consistent quality that made the company meet the ISO 9001, ISO 14001, ISO/TS 16949, EN 9100 and MIL-Standard 790 standards.

As a leading manufacturer of screw-machined contacts, PRECI-DIP has the track record of producing more than 20, 000 different products. PRECI-DIP has shot to fame internationally by manufacturing high-reliable spring-loaded contacts for different industries.

The Mil/Aero contacts, used in aircrafts, missiles, helicopters is the line of products  that made PRECI-DIP earn greater reputation in defence industry for meeting stringent aerospace standards. PRECI-DIP has developed 300 high-speed turning machines, producing precision contacts, made of various copper alloys with a total capacity of over 150 million pieces per week.

We have expert team that work in close partnership with customers to understand the ever changing requirements of modern day business. We are always eager to take the challenge to develop great products and solutions for custom applications driving high output and rendering flexible options that accommodate customer ideas.

Contact Design


The contact consists of three parts, separately manufactured and made of different base materials. This design allows to optimise the performance and to select the most appropriate production process individually:

  • Contact body made of machined brass
  • Beryllium-copper clip insert achieved by precision stamping process
  • Protection hood made of deep-drawn stainless steel

Separate electroplating processes of body and clip allow the best cost-performance ratio (localized finish). The assembly of the three parts is then carried out on dedicated, fully automatic assembly lines.

Reversed clip contacts are presently available in size 12, 16, 20 and 22. This proprietary technology developed by PRECI-DIP, is protected by international patents.


In comparison with the alternative slotted contact body design, the reversed clip concept has several advantages:

  • Smaller difference between insertion and extraction forces
  • Reduced dispersion of the force values
  • Higher redundancy of the contact points, thanks to 6 or 8 con-tact fingers

We are also manufacturing the corresponding precision-machined pin contacts.

These contacts have successfully passed all the qualification tests according to AS39029 and are QPL listed
