WITH OUR PLIERS YOU HAVE EVERYTHING UNDER CONTROL!
Our high quality blank steels are either hot forged in forging dies or laser cutted. So we achieve structural conditions which ensure quality and long life time for our final products. According to our strict internal rules we handle the production process on top modern machines. Finally the pliers are oil hardened and the tips get an additional inductive hardening, for highest requirements.
[Translate to English:]
(N / mm² = tensile strength)
|soft wire:||copper, plastic, aluminium, 220 - 250 N/mm²|
|medium hard wire:||nail, wire pin, 750 - 800 N/mm²|
|hard wire:||steel wire, steel pin, 1600 - 1800 N/mm²|
|Piano wire:||hardened spring wire, 2200 - 2300 N/mm²|
Depending on model and technical requirements, we use high-alloyed tool steels or high grade ball bearing steel (chrome steel) from selected suppliers which fully comply with our needs.
CUTTING SHAPE AND CUTTING CAPACITY
The life time of the cutting tips depend among others on the sharpness. The sharper the tip (Full Flush) the faster the wear. For this reason, pliers in Semi Flush or Flush are preferable so far no Full Flush and shock reduced cut is necessary.
applicable in case of hard and soft steel wires as well as for soft materials, e.g. copper wire; the cut leaves at the end of the wire a peak similar to a pyramid.
nearly a flush cut with fine tips; applicable for soft steel wires and copper wire; cut slightly shock reduced; at the end of the wire only a small peak
cut absolutely flush; extremely sharp tips; exclusively for soft wires and copper wires; shock reduced cut; absolutely plane-parallel
for cutting of glass fibre, Kevlar etc.
HARD METAL EXECUTION
with inserted hard metal tips, for continuous heavy work, also for tough nickel and electrode wires
For several centuries we have developed surface characteristics for different applications and standards. Those characteristics are protection against corrosion, hardness, wear and tear, break-offs, smoothness and surface roughness which are suitable for the specific applications and optimum operation results.
We manufacture electronic pliers with 4 different joint constructions depending on application and execution of the pliers series. The simplest joint is the lay-on construction. Both pliers parts are simply riveted together. This execution is only for bigger sized pliers. In case of the lap joint solution, both pliers joint planes are milled out, bedded together and subsequently riveted.
The most complex solution is the box joint construction. In a very special process the joint is made by sliding one pliers head through the under heated opened joint of the other pliers part. After that the joint is pressed together and tightened by a rivet. This construction ensures best parallel guidance of pliers´ tips and an extremely long life time.
The highly precise manufactured joint planes of the screw joint construction provides an accurate jaw adjustment without backlash and a smooth friction free open-close movement. In combination with the basic hardness of the chrome vanadium ball bearing steel the screw system ensures a very high cutting capacity with a long life time.
Either a pressure or an interchangeable double leaf spring from stainless steel provides a smooth and equal open-close movement. The life time of all pliers can be extended by a drop of acid-free oil on the polished planes and in the joint.
