Our products

Non-precious metals

From gold to platinum, PX GROUP and more precisely PX PRECINOX, handle precious metals on a daily basis. Once the alloys have been made, they are worked by rolling and cold-drawing, and then deformed to obtain semi-finished products. They are then delivered to partner industries, mainly in watchmaking, jewellery and luxury goods.

NON-PRECIOUS METAL PROFILES

Wide or shaped non-precious metal profiles are an inherent part of PX’s in-house tailored solutions, tailored to every customer’s requirements.

Certain complex profiles are produced by cold rolling or drawing, with on occasion continuous machining in addition.

CLAD TUBES


Corrosion resistance, high mechanical properties, high electrical conductivity, attractive prices: the group’s exclusive manufacturing process enables it to create multi-metal combinations optimising the qualities of the finished product.

APPLICATIONS

  • Medical devices
  • Measurement instruments
  • Electrical contacts

ALLOY COMBINATIONS

NON-PRECIOUS METAL WIRES


Non-precious metal wires, of various diameters and admirable precision.

The company offers a range of wires varying in diameters from 0.70 mm to 5.00 mm.

MULTI-METAL WIRES AND PROFILES


Optimising the qualities of the finished product through multi-metal combinations: the firms have an expert command of both theory and technique. An in-house exclusive, which stands out from combinations for parts comprising a single alloy.

APPLICATIONS

  • Medical devices
  • Measurement instruments
  • Electrical contacts

ALLOY COMBINATIONS

  • 10% PtIr plated on stainless steel, nickel, titanium, tantalum, niobium or silver
  • AuAgCu alloy plated on stainless steel, or copper alloy
  • Stainless steel or superalloy plated on copper or copper alloy
  • Other combinations and tri-metals on request

DIMENSIONS

Ø 0.1-5 mm, sheath 4-40% of the diameter

QUALITY CONTROLS

  • Eddy currents
  • Metallographic analysis

DELIVERY FORMAT

  • Straightened, up to 3 m long
  • As finished parts

EXTRUDED CASE MIDDLE SECTION FORMATS


The cold-extruded and gauged sections can be delivered in various formats.

The slug thickness should be defined according to customer requirements, the minimum thickness being 6.0 mm. This guarantees the overall shape tolerances [+/- 0.03 mm], for both case middle hoops and the horn lugs (by means of reworking if the radii to obtain are less than R 0.6 mm).

The horn lugs or case middle hoops are “reference surfaces” for the successive machining / turning operations, as well as for the case finish preparation operations, or for stamping post-operations.

The extruded case middle sections are delivered in the form of bars 600 mm to 700 mm long, with straightness [+/- 2.00 mm].

ADVANTAGES

“Hot-extruded and cold-rolled” technology represents a real savings opportunity for manufactures which are seeing their margins shrink because of the strength of the Swiss franc. And also for the established brands, which over the period 2017 – 2020, will have to step up the Swiss made concept.

  • Costs and tooling production times are lower than with stamping.
  • The technology is ideal for small runs in the prototype phase.
  • The materials are optimised, and waste production is lower.
  • A better surface finish (close to Ra 0.4).
  • The hardness can be defined /tested (according to the cold working applied in the process).

NON-PRECIOUS ALLOYS


PX GROUP can draw on a background going back more than four decades in working and transforming metals, to meet its customers’ needs via tailor-made solutions.
