Top quality in production

Because engineering needs a solid foundation.

Developing a product with ARNOLD means that you are working with specialists who know what they are talking about.
The foundation of this is formed by our international production sites where we generate top quality products on the most up-to-date machinery and using modern technologies.
Integral processes such as toolmaking, heat and surface treatment, and a honed quality assurance system all ensure that the products and services we supply are safe and reliable.

Toolmaking

Our toolmaking facility with the latest equipment gives optimum support to the manufacturing departments, while also ensuring flexibility and effectiveness.

Heat treatment

In-house fully automated hardening furnaces reduce transfer times and optimise internal processes.

Pressing

In the dual pressing section we can press a huge variety of products in large quantities and under constant process supervision.

Surface treatment

Our own electro-plating unit efficiently applies a wide range of standard surfaces to the highest quality.

Rolling

The existing plant and machinery can produce standard and special threads, and also components with nondetachable washers.

Ultra-fine cleaning

Cleancon® the latest laboratory technology and an ultra-fine cleansing system with its own clean room ensure that we comply with a high level of cleanliness requirements.

Multi-stage cold-forming

The latest forming technology (up to seven forming stages) enables us to produce cost-optimised precision and multifunctional parts.

Quality assurance

Consistently enhanced employee qualification and intelligent inspection technology (automated sorters, climatic chambers etc.) ensure high quality.
