Result of pioneering research by BOLZ INTEC & Konstanz University of Applied Sciences

The Optimized Grind Finishing process (OGF)

In the pharmaceutical, chemical and food processing industries, minimizing build-up in containers is a critical factor for efficiency and quality. The build-up of substances on the inside walls of containers can lead to increased cleaning effort, product losses and contamination. This costs money and ties up resources. Especially in industries where EHEDG (European Hygienic Engineering & Design Group) certification and hygienic design are becoming increasingly important, minimizing adhesion has become a critical factor.

Research carried out by BOLZ INTEC in cooperation with the University of Constance has shown that the way in which stainless steel surfaces are removed plays a key role in minimizing adhesion. Different grinding methods result in different adhesion behavior, despite the same Ra values, and the OGF process from BOLZ INTEC leads to a lower adhesion of particles.

Below is a scanning electron microscope image of the stainless steel surface after electropolishing and Optimized Grind Finishing, as well as images of the surface texture roughness data and repeatability.

Easy cleaning & minimal adhesion

The Optimized Grind Finishing (OGF) process leads to a low adhesion of particles on the surfaces of the containers. This significantly improves cleaning efficiency and reduces the risk of contamination of product batches.

Reproducible surface quality

The OGF process enables reproducible surface quality. In contrast to conventional processes, in which variable factors such as manual contact pressure or the quality of abrasives play a role, the OGF process offers consistent surface quality.

Visual aesthetics and low number of errors

The stainless steel surfaces treated with the OGF process have an attractive appearance and defects in the surface structure are significantly reduced thanks to the fine and gentle removal process. This is particularly important in industries that place high demands on safety.

Improved corrosion protection

The electropolishing process not only improves the optical quality, but also results in chemical changes that lead to improved corrosion protection. This is particularly relevant for applications in chemical and pharmaceutical processes.

Reduced risk of batch contamination

The improvement in cleaning behavior through the OGF process leads to a significant reduction in residual dirt adhesion in the containers. This significantly reduces the risk of contamination between different product batches.

Applicability in critical industries

The process is seen as particularly advantageous for critical industries such as nanotechnology or biotechnology and pharmaceutical technology, where the highest purity requirements and the avoidance of contamination are of crucial importance.

Why customers around the world choose our stainless steel drums

Tradition & innovation since 1919

BOLZ INTEC specializes in the manufacture of stainless steel drums, pressure vessels, agitator vessels, transport containers and transfer systems for hygiene-sensitive industries.

High vertical integration

BOLZ INTEC has acquired outstanding expertise in the machining of stainless steels and special materials such as Hastelloy. Combined with the skills and abilities of our team, this enables us to achieve maximum vertical integration. All production steps are carried out in-house. BOLZ INTEC is therefore able to react extremely flexibly to customer delivery date requests and guarantee unique quality.

Customized solutions

Our design department designs, plans and develops practical products according to our customers' requirements. These include, for example, containers for pasty substances or liquids, transport containers for UN hazardous goods, cans for the storage and transfer of active ingredients, suction hoods for dust-free container loading and much more.

One-off production & small series

BOLZ INTEC also manufactures custom-made products and small series.

Machines for perfect surfaces

Nothing in the BOLZ INTEC machine park is off the shelf. From the deep-drawing press to the electropolishing system, we work with special machines that have been developed according to our own specifications in order to meet the highest standards of quality and precision.

Traceability & reproducibility

BOLZ INTEC's QM system and our intensive testing procedures ensure the consistent quality of the stainless steel surfaces manufactured by BOLZ INTEC. In this way, we make a decisive contribution to the traceability of products in critical industries. 

Trust & security

Our striving for perfect quality, state-of-the-art production methods, but also craftsmanship and know-how are the basis for the superior BOLZ INTEC quality, which means safety and reliability for our customers. It is therefore not surprising that 80% of our customers have reordered every year for the last 10 years.

Comprehensive certification

We regularly have our quality certified externally: DIN 9001:2015, DIN EN ISO 3834-2:2006-03, DIN EN ISO 115085-2/CL1. We are a specialist company according to WHG §19/1 and carry out process tests according to DIN EN ISO 15614-1, operator tests according to DIN EN 1418. BOLZ INTEC fulfills the Pressure Equipment Directive-2014-68-EU/AD-2000 HPO and employs Intern. Welding engineers (DVS/IIW 1170).

BOLZ INTEC offers you decisive advantages

High efficiency, low costs & great economy

Time savings in production

The use of stainless steel containers with optimized surfaces leads to significant time savings in the production process. By minimizing the build-up of materials, cleaning and maintenance times can be drastically reduced. This enables the containers to be reused more quickly and increases the overall efficiency of the production lines. In a production-intensive environment where time equals money, this time saving represents a significant economic advantage.

Reduced risk of production downtime

The reproducible quality of the stainless steel surfaces and the reduced number of defects minimize the risk of production downtime due to surface problems. This can lead to higher overall productivity and less downtime.

Reduction of production losses

Optimizing the container surfaces also minimizes the amount of product loss. Reduced adhesion means that more of the material produced is available for its intended use and does not end up as waste. This is a particularly important factor in industries where high-quality or very expensive materials are processed.

Improvement of product quality & product safety

Contamination-free production results in a higher quality end product. This is crucial in industries with strict quality and purity requirements, such as pharmaceuticals and food production, where purity and safety are top priorities. The use of optimized stainless steel containers can therefore also lead to improved brand image and customer satisfaction. We ensure the quality of our containers through our QM officer and stringent production processes. You will receive the corresponding documentation for each of our stainless steel drums.

Cost reduction through efficient cleaning & barrel maintenance

In addition to saving time, optimized surfaces also lead to a reduction in the costs of cleaning processes. Less build-up means less need for cleaning agents, water and energy. There is also less wear and tear on the containers themselves, which increases their service life and reduces the need for new purchases. In the long term, these savings in operating costs can make a significant difference to a company's profitability.

Longer container service life & positive eco-balance

The improved corrosion protection provided by the electropolishing process helps to extend the service life of stainless steel containers. Customers can thus reduce their costs for replacement investments and maintenance.
