Top quality in production

Because Engineering needs a strong base.

Integrated processes such as toolmaking, heat treatments, and surface finishing, along with a sophisticated quality assurance system, all ensure reliability in all ARNOLD products and services.

Toolmaking

Our tool-making 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.

Multi-stage cold-forming

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

Sortec®–Quality assurance

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