Tools for Injection Moulding and High Pressure Die Casting

What we offer

The production of injection moulding and high pressure die casting tools has a long tradition at Grunewald. Starting with the design of the product, the raw parts and the tools are consecutively build up applying different CAD systems. The fast transformation of CAD designs to milling, eroding and assembly is an important precondition of the short tool production cycles at Grunewald.

What we are looking for

Pressure die casting companys, who need prototypes out of sand casting

Tools for the Aircraft Industry

What we offer

Grunewald produces tools for carbon fiber reinforced plastic components for the aircraft industry. These large tools are designed and produced since many years at Grunewald in a highly effecient and competent way.

For the design and production of these tools, modern CAD/CAM equipment and various 5 axis machining centres with up to 14 meters length are available at Grunewald. As an example, Grunewald is currently involved in the development, design and production of tools for the new wide-bodied aircraft Airbus A380.

Automotive Tools for Soft Interior Components

What we offer

The interior of modern vehicles is protected against acoustical influences from external and internal sources by means of a number of complex insulations. Typical car interior linings are engine compartment insulations, textile wheel house linings, dash panel insulations, floor insulations and carpets etc. .

Since many years, Grunewald belongs to the leading producers of tools for the “soft interior” of passenger cars or heavy goods vehicles. Typical examples for the tools produced are carpet forming tools, foaming tools, deep drawing and cutting tools.

Casting Products

What we offer

Since ca. 20 years Grunewald delivers casted prototypes and small series productions to automotive, aircraft, mechanical engineering, computer and medicine industry worldwide. The castings will be ready machined, surface treated and accomplished by extensive quality controls.

Grunewald uses the following casting techniques:

-Qualified Master Casting - QMC
-Sand Casting
-combined manufacturing techniques

Casting alloys are Aluminum, Magnesium and Iron.

The special competence of Grunewald is the technical and economical analysis and decision support to find the technical and economical best casting solution.

Typical castings are motor blocks, cylinder heads, oil sumps, suction pipes, turbo charger housings, gearbox housings, holders, frames, axsis, structural castings and more.

Looking for CFK components for water jet cutting

What we offer

Since 2009 Grunewald machines so called "Stringer-Profiles"; of carbon-fiber-reinforced plastic (CFRP) for the aircraft types A 380 and A 400M.

This challenging work is carried out with a multi-axle jet cutting equipment capable to cut in dimensions of 12m x 3m.

High quality cutting profiles, rapid lead times and high productivities characterize this relativly new technology.

What we are looking for

CFK components for water jet cutting

Mechanical Machining

What we offer

One of the most important work areas at Grunewald is the mechanical machining. Nearly each component, that is produced at Grunewald, even if it is a complex cylinder head or a big seized tool, is machined on various kinds of CNC-milling machines. Beneath our internal and project dependend machining we offer seperate machining services.

Grunewald has got different CNC-machining capacities. From small machining centres for the machining of e.g. casted prototypes, like cylinder heads and suction pipes, etc. up to large machines with machining possibilities up to 14.000 mm for the machining of large components (picture left) we are able to machine all kinds of products and tools.

Series Assembly of Aircraft Components

What we offer

Grunewald assembles aircraft rudders since 2008.

Inside of new production facilities Grunewald assembles and qualifies side rudders of the Airbus family types A318 to A320 and A 330 to A 340. The qualified rudder assemblies are delivered to Airbus & just-in-sequence;. Grunewald produces currently up to 490 side rudders per year. Most of the production devices have been developed, designed and manufactured by Grunewald.

Rapid Prototyping

What we offer

The direct and indirect production of functional prototypes starting from 3D CAD-data is realised with selective laser sintering and the technology of stereolithography. With the help of these technologies Grunewald produces direct plastic models and patterns e.g. for castings. The material properties of strength, thermal behaviour, surface quality and accuracy to gage are similar to series production models and patterns.
