Sustainability and qualityOur commitment to mould making and mechanical engineering

With Siegfried Hofmann GmbH, you have a partner for tool and machine solutions with a view to a sustainable future. We are actively committed to sustainable practices to both protect the environment and provide added value to our customers.

Our ongoing sustainability measures and certifications reflect our commitment to environmentally friendly processes and efficiency improvements: From utilising energy efficient manufacturing technologies to complying with international environmental standards.

CO₂ footprint calculation for your tools

Sustainability counts – and can be proven! We can calculate the carbon footprint of your new injection mould on request.

The calculation is based on the Greenhouse Gas Protocol (GHG), the internationally established standard for assessing emissions. The result: a transparent, comprehensible CO₂ balance sheet – without any fancy calculations or unnecessary complexity.

  • Material, purchased parts & external services: We calculate based on expenditure (Climatiq database) instead of purely by weight.
  • Production: Energy consumption is calculated using actual machine hours – and with 100% green electricity since 2024, there are no CO₂ emissions.
  • Transport: Factor-based calculation (Climatiq database) of actual transportation, taking into account the weight of the tool.
  • Recycling: Approximately 98% of a tool is made of steel – its recycling at the end of use is included in our carbon footprint.
