We see ourselves as a service company, which provides them with metal products for your production. Either you have drawings or samples and we make them a cost-effective offer or you have an idea and we design for the parts, they bring to the production stage and deliver them cost-series parts.

In many cases, we keep our customers ahead of a warehouse from which the customers get smaller batch sizes.

Our clients use our services for both series parts as well as for items, samples or spare parts for machines to complete.

Our focuses are:

In sheet metal forming, laser cutting, welding, edge and case, lasers of pipes.

When turning and milling, also gears.

Frame construction, frames for upholstered furniture with functional parts, accessories, parts for office chairs, carts for internal transportation, racks for shopfitting.

The ITF precision GmbH is specialized in high precision machining of parts in the field of grinding (outside and inside), surface grinding, honing, and in the full processing for the food industry, mechanical engineering, automotive and medical equipment from raw material to finished part. We offer everything from turning, milling and coatings to heat treatment from a single source.

A further specialization, we have in the area of pumps and hydraulics, by modernize and overhaul of gear pumps and hydraulic components.

- Subcontracting loops
- Manufacture of tools and devices
- Combined machining turning, milling and grinding
- Manufacture of plain bearing bushes
- Rework pump shafts
- Rework pump housings
- Manufacture of hydraulic pistons and housings
- Manufacture of control edges and sealing surfaces

We are a mittelständiches company with about 10 employees. We are manufacturer and supplier of vacuum vapor deposition for the packaging and semiconductor industries and the construction of special machines for sheet metal machining and toolmaking.

We have our own mechanical production with three CNC milling machines and two CNC lathes and other three conventional lathes, a hydraulic drawing press, a CNC band saw, several punching machines and other machines around the metalworking including a welding and electrical cabinets.

All systems can be manufactured according to your specifications or designed by us on request, built, electrically connected and put into operation.

Our assembly hall is 20x50m and has a 25t Kran.Einzelstücke up to 4500mm width, 3500mm 15000mm length and height are at a stretch without special effort transportable,.

ITM GmbH was able to become successful in the fields of special purpose machinery, vacuum technology, prototyping and cryo-technology and through expertise and experiencevm position. Products such as vacuum vapor deposition, vapor deposition, cold traps and punching tools are made by an experienced employee base. When special machine and fixtures, cutting tool making and in the cryo-technique individual customer requirements are accurately implemented. As a reliable partner, we offer you in cold traps and Meisnerfallen from the cryo-technology excellent quality. Whether vacuum technology, vacuum vapor deposition or Gauge, permanent material control is self-evident for us.Our high quality metallizers find, among other things their use in the food industry.

The expert advice for optimal use of the tools are vendor-neutral and on request also the customer's site.
Are offered a wide range of innovative tools and coatings. Renzelmann leads both brands leading brand suppliers as well as our own product lines with proven quality and outstanding value for money. Also develops and produces Renzelmann individual special tools according to customer or optimized the geometry of existing tools as needed.
Worn out tools put the well-trained and experienced staff accurately repaired. Both in making and repairing the computer-aided tool grinding machines (CNC) come with up to five axes for the course.With the help of minimal tolerances are maintained during processing. Documents the high quality is also CNC controlled laser measurements.
For the following separation processes Renzelmann provides the appropriate tools and services:
- Cutting: shear cutting and knife cutting
- Machining: Turning, drilling, reaming, milling, planing, slotting, broaching, sawing and chiselling.
In addition, the company provides its customers with appropriate accessories and equipment, such as cooling lubricants and equipment for minimum quantity lubrication.

The processing time for the repair is five working days normally. In urgent cases, the processing is done by arrangement overnight. In addition to a possible Europe-wide delivery by logistics partner, a nice pick-up and delivery service is available within a radius of 150 km around Bremen.

Corresponding differences in the industries in which the customers operate.


History

Founded back in 1954 by Irmgard and Johann Renzelmann primarily for machinery trade, the J. & G. Renzelmann GmbH developed in the course of its history to become a recognized expert in grinding technology which now has some 15 employees.
Since 1985, the Bremer family business is run by brothers Jürgen and Gerd Renzelmann. Also dates from the 1980s, the membership of the Technical Association of German precision tool grinder (FDPW), where Gerd Renzelmann as a board member already takes over 10 years of responsibility.
Meanwhile, with Mario Renzelmann already the third generation of the family entered the business.
