The Environmental Policy of WENESIT AG

Sustainability ensures our future business. Therefore we focus our efforts to conciliate the ecological, economical and social challenges to design and manufacture environmental friendly products.

Our environmental policy is based on the responsibility for mankind and the environment. Our contribution to the protection of the environment focuses on avoiding hazards and reducing risks.

The following guidelines are designed to be used in implementing the environmental policy in the company:

  1. We are constantly working at going beyond merely adhering to regulations in order to reduce environmental impacts and risks and the consumption of energy and resources.
  2. We take every necessary measure to prevent hazards and damage to the environment.
  3. Appropriate management methods ensure that our environmental policy is implemented effectively. The required technical and organizational methods to achieve this task are regularly inspected and constantly developed further.
  4. Each and every member of staff is tasked with acting in manner that is environmentally aware. It is an ongoing task of management to grow and promote a sense of responsibility at all levels.
  5. We encourage our business partners to act in accordance with our guidelines. We cooperate closely with the relevant authorities.
  6. We inform those members oft he public who are interested of any environmental impacts caused by the company and of our activities in relation to the environment. We provide our customers with information on how to use our products in an environmentally friendly manner.

The tasks associated with this must be seen to be an integral part of corporate policy in all parts of the company. This applies to all aspects of the company, to Purchasing just as much as to Development, Design and Manufacturing, and right up to Sales and Service.

Environmental protection and technical safety are the concern of each and every member of staff in the company. Observance of relevant legislation takes absolute priority.

One of the management´s efforts is to put in place the conditions that the safety of people and the protection of the environment are taken into account in all activities. The objective is to minimize any negative environmental impact caused by both the products and by the manufacturing methods.


Research and Toolmaking

The route from what is theoretically possible to a practical implementation runs through the development stage.

This is where Wenesit’s work begins, supporting you together with our project partners of many years and using simulation software, before serial production even begins, to create feasibility and feasibility of manufacture analyses of various kinds. Involvement in development projects from an early stage allows us to deliver a punctual, economically viable product development that is suitable for plastics. Various prototype production methods and/or manufacture with auxiliary tools also allow small sample or pre-series batches to be produced.

Our high-quality, durable tools secure a profitable production run at all times. With our tool suppliers and our specialists for in-house mold construction we design, fabricate and preventively maintain all our injection molding tools. Each individual tool is signed off to the desired process capability before series production begins and is documented together with the series production outcomes in accordance with the customer’s documentation format and archived for the entire duration of the product lifecycle.


Wenesit produces precision plastic parts from 0.1 g to 400 g mold weight.

The newest hydraulic and electric production systems facilitate production processes that are reliable and economically efficient. With our extensive periphery and some 30 hydraulic and fully electrically driven production systems from the manufacturers ARBURG, Wittmann-Battenfeld and Dr. Boy, we are able to manufacture plastics products of all manner of colors, sizes and geometry. We manufacture solely with 1a granules and color concentrates using flexible multiple shifts on all weekdays. In addition to the technical and standard plastics, for processing we also use high-performance plastics such as PPS and PEEK.
