The Sumitomo Heavy Industries group perceives global environment protection and recycling-oriented economic activities as corporate social responsibilities. Thus, we are promoting environmental management.
Calls to reduce environmental impact of plastics have been increasing in recent years.
Below we would like to introduce some case studies that can be useful in achieving carbon neutrality, one of the key challenges in achieving sustainability.
As an injection molding machine manufacturer, we will continue to provide products and services contributing to the sustainability achievement.
Our business activities are aligned with Sustainable Development Goals (SDGs).
We are a member of the Japan Clean Ocean Material Alliance (CLOMA), which promotes efforts in solving marine plastic litter issue all around the world.
Carbon neutrality can be achieved by balancing greenhouse gas emission and absorption volume. For this purpose, it is necessary to enhance the reduction of carbon dioxide (CO2) emission, as well as other greenhouse gases, and increase its absorption.
Because reduction of CO2 emission volume is required during production process, injection molding machine must be equipped with functions reducing utility and resin consumption.
* The volumes of CO2 emission, resin and utilities mentioned for case studies below depend on molding conditions and operation hours.
Reduction of electric power consumption, cooling water and oil by improving energy efficiency
Minimization of clamping force and reduction of power consumption by MCM
Zero-molding is an integrated application that helps to minimize Defects, Losses and Faults. It includes three technologies: MCM (mold clamping technology), FFC (filling technology), and SPS (operation technology).
Reduction of grease consumption by grease supply system optimization
Reduction of resin necessary for color change by automatic switching of purging conditions
