What is phosphating springs?
Phosphating laying a layer of insoluble phosphates in the technical spring.
Phosphating of technical springs gives a better protection against corrosion. In addition to protection against corrosion, it also gives a wear layer for springs, which have severe applications in moving parts of machines.

What is the cleaning of springs?
The cleanse of springs ensures that can be provided a technology spring without chemical resedue. Of these, the precursor is ASML.
Inexal operates with ASML grade 2 and grade 4 standards in order to cleanse the springs. We keep the standards of ASML because these define the market quality. All technical springs are available with this treatment. The cleaning of springs cleans the spring, of any chemical residues. This is important for products that must be perfectly clean.

What is electrolytic pickling of springs?
In the electrolytic pickling and etching the technical springs are connected to a power source and immersed in a pickling or etching solution. This ensures that that the oxide skin better release of the technical spring.

What is the passivation of springs?
Passivation is often the process, after pickling in technical springs. This provides the technical spring in stainless steel again back to its original corrosion protection.

What is Powder Coating of springs?
The powder coating provides a coating layer of fine powder on the spring.
Powder coating of technical springs gives them a good protection against corrosion. It the powder coat is more environmentally friendly than most surface treatments. The powder coating of Inexal has passed the ISO salt testing. This guarantees protection against corrosion.

What is tinning of a spring?
The tin-plating of a spring, gives the spring gives a layer of tin.
The tinning of technical springs is conventional in bronze products in the electrical engineering. Furthermore for technical springs used in soldering. These combine with the tinning of technical springs gives a good solderability.

What is the electolytisch polishing of springs?
Electropolishing of technical springs gives a smooth surface. In particular for use of processing springs in the chemical, pharmaceutical, transport and surgery, this is an important process. The electrolytic polishing of springs is mostly combined with the cleaning of springs. With both processes, the spring is fully suitable for tasks where there can't be any contaminations.

What is shot-peening of springs?
Shot blasting as a method for substantially improving the opererende- (fatigue) service life of springs, is certainly not new. The commercial origin of the art goes back to the auto industry from about 1930, and today use almost all cars blasted valve springs and, in many cases, suspension springs . This is also the case with the suspension springs Inexal. But this treatment is suitable for regular technical springs. The shot peen process is relatively inexpensive and has proven to exceed the life span of springs, five to ten times or more as compared to uncured springs.

What is Au-plating of springs?
Au-plating, the gold plating of the technical spring. The technical spring is provided with a thin layer of gold. Gilding on technical springs is used in the semiconductor and electronics industry for various applications. The gold plating of technical springs ensures a good chemical durability and a hardness of 150-200 HV (85HRB). In addition, the gold-plating of technical springs improved contact resistance

What is the brass-plating of springs?
The brass-plating gives a brass layer on the spring. Brass as surface treatment is done mainly for decorative purposes. In addition, an application for this purpose also suitable to improve affix rubber to steel too.

What is the chrome plating of springs?
The chrome plating of technical springs is done by a galvanic process. The chrome plating is used to provide springs protection against corrosion and / or wear-resistant. Further, the chrome plating provides a beautiful silver sheen to the technical spring.

What is the Zinc-plating of springs?
The Zinc-plating (galvanizing) of springs is adding a thin layer of zinc onto the technical spring. Thanks to the galvanizing springs are better protected against corrosion. Zinc galvanized springs are free from the constant threat of corrosion and provide a longer lifespan. The disadvantage of galvanized springs is that they tend to lose their tensile strength after a period of time.

What is nickel-plating of springs?
Nickel-plating of technical springs provides springs with a layer of nickel. The nickel is a protection against rust and other corrosion. Nickel prevents migrates the base material for the precious metal surface, so it can't get dirty. Nickel can be done electrically and chemically.
