We are a young company headquartered in Velbert that is reinventing parts procurement in the area of additive manufacturing. We produce semi-autonomously 24/7 using the latest FDM-3 printers. For us, quality, speed and price performance are our priorities. We supply the automotive industry, mechanical engineering and special mechanical engineering companies in series, among others. We are at your side with advice and support to achieve the best possible result for you.

We are a family company based in Munich (sales) and a production facility in Croatia near Zagreb. We have specialized in injection molded components in the prototype area. We can also offer smaller stamped components and turned parts. For more information, do not hesitate to contact us.

The tool management includes:

• Check the tool drawings in collaboration with customers
• Create schedules in MS Project
• Ongoing status reports
• On-site monitoring of the toolmaker
• monitoring compliance dates
• Progress Monitoring
• Review getätigter work
• Reconciliation schedules with customers and suppliers
• root cause analysis of delays and action planning
• vote to be carried out tool changes or their fastest possible implementation
• Tool will inspect tool acceptance report

The ever shorter lead times for the development and production of prototype and production parts, especially in the automobile sector, demand a detailed planning of the individual or parallel projects to save costs and time.

We offer complete transparency regarding the project progress, the crucial exercises to project success. To ensure that your project goes according to plan, our team takes on the progress monitoring tool and provides the appropriate status reports.The earlier we are entrusted with the management tool, the easier we can make reference to the flowcharts, bottlenecks and Narrow by concrete measures. Tool changes to be managed in the short term and on time from us.

Based on available data of the components, we assume the timely procurement of necessary resources such as tools. In consultation with you product features, function, and any added components will be discussed. Thus, the optimal process engineering can be determined and the most suitable manufacturer can be selected.

We will also guide you in its care: scheduling, determining the organizational and technical processes, to process optimization procedures, for the precise implementation. The documentation of all processes and changes in the life cycle is a matter of course.

Pending the completion of the project, we are your partner.

Tool and die
Injection molding tools; small batch tools and prototype tools made of aluminum includingProduction of components; Space Puzzle Molding; RRIM tools, stamping tools, die-casting molds, trimming or deburring tools; production of small series for general engineering (up to 1,000)

We deal with prototyping, construction of steel molds, production of plastic parts by injection, aluminum die-casting and turning.

Prototyping in all materials available for 3D printers, numerically controlled machines or silicone molds for pre-series, necessary in the first experimental or production phase.
We treat all types of plastic material including the transparent and the diffusing opal. In the metals field we work mainly with aluminum, stainless steel, brass, zamak. We have a lot of experience in the medical field, lighting technology, vending and coffee machines

Each year, we produce around 20 million injection moulded parts, primarily for the automotive industry. The parts we produce are used in the following vehicles, among others: Audi, Bentley, BMW, Chrysler, Maybach, Mercedes, Opel, Porsche, Rolls Royce, Seat, Skoda, Toyota, and VW.
The following international automotive suppliers form part of our customer base: Continental Automotive GmbH and ITW Automotive Products GmbH. We deliver to locations in Australia, Brazil, China, France, India, Indonesia, Malaysia, Mexico, Switzerland, Spain, and the Czech Republic.
We currently keep more than 2,000 injection moulding in working order in order to meet our customers’ needs. Specialist personnel service and maintain machines and carry out small repairs on our premises. Following a joint development process, new moulds are produced by experienced tool manufacturers in the close vicinity.

P / S KUNSTSTOFFWERKE AG is an innovative medium-sized company in the plastics processing
Industry with an own tool.



From over 1000 tools, we produce technical plastic parts from 0.1g to 2.0 kg on powerful
Injection molding machines with a clamping force of 150 up to 5000 kN and presses with clamping forces from 600 to 3000kN. Product-specific handling systems and peripherals to ensure safe production process
at a consistently high level of quality.



From our many years of experience in the processing of thermosets and thermoplastics materials (unreinforced,
reinforced, modified or high-tech plastics) can
our customers always benefit.



The diversity of our production program, below are some examples, requires a special expertise.



Plastic parts with a highly polished, verspiegelbarer surface design as part or plastic-metal
Compounds;
System and component assembly;
Pure assembly work;
Printing, welding and two-component injection molding.

PTG GmbH was founded on November 10th, 2006 by the company Gröber Metallverarbeitung. The core competence in surface finishing through superfinishing was supplemented by the strategic procurement management of drawing parts and assemblies as well as the trade in sliding elements.
