Complexity,
our daily challenge

Plastic injection parts

Thanks to our computer numeric control (CNC) electrical discharge (EDM) machines, what was impossible to produce in the past is now possible! It is now easy to machine extremely intricate shapes, making it possible for us to respond to a wide range of customer requests.

CASING RINGS

Casing rings are mainly injected using Grilamid (PA 12). This material provides high rigidity and enables the insertion of flexible suspension bridges. They hold the movement in place and absorb shocks that the watch could suffer. All colours are available.

The tooling costs, for a standard casing ring, without complication, is less than CHF 3'000.-. It is guaranteed for about 500'000 parts. In the costs are included :

  • Tooling design
  • Tooling manufacturing
  • Molding tests
  • Any alteration
  • Production
  • Maintenance during the warranty

GASKETS

Gaskets can be round or in other shapes, flat or galbed and can be made in different materials :

  • HYTREL : Whitish material with a perfect hardness for gaskets (72 shores D). Plastic injection possible in every shapes and colours. Also available in turning bar (only white and black and Ø 15 to 48 mm).
  • ZYTEL : Translucent material and relatively hard (86 shores D). Only possible in plastic injection. Every diameters, shapes and colours are available. Large choice of diameters with one angle.
  • SANFIL : Please see on this link "Products - Turned and CNC machined products"
  • GRILAMID TR90 : Hard and transparent material with a few memory. Not advisable because it is a single use gasket.

TRANSPARENT GASKET

Development of these last years in term of material allows today to satisfy nearly every needs. In order to bridge the remaining gaps, Henri Schaller SA developed a new gasket combining elasticity and transparency characteristics. ELASTRANS® can now replace Hytrel material for watch crystal gaskets. It has an excellent UV resistance, is pratically invisible and maintains all its elasticity, even following a large number of removal and reffiting operations.

DIAL AND MOVEMENT CONTAINERS

In close collaboration with our customers, we develop dial containers and movement containers for fully secure transportation of watch dials and movements.

Our container allows to the dial upper face to be in contact with nothing.

It is important to define all the factors affecting the part to be protected in order to select the most suitable material. Henri Schaller SA can also offer movement protection container made of anti-static plastic.

We have different standards dimensions :

  • Ø 35 mm
  • Ø 45 mm
  • Ø 60 mm
  • Square 40 x 40 mm

The logo of your company or Brand can be engraved in relief on the cover.

Samples can be provided to interested parties.
