Development and design efforts

Unipres has contributed to weight reduction, improved fuel efficiency, and enhanced safety by improving car body press, precision press, and plastic press technologies thanks to our base technologies relating to materials, molds, equipment, and quality assurance.

■Optimal lightweight structure proposal

Unipres has been working to develop molding technology for processing high-tensile materials, ultra-lightweight parts made of foamed plastics, and more. We propose to our customers an optimal lightweight structure that realizes both performance and productivity by capitalizing on the strengths of total press engineering, which handles everything related from pressing from product design and development to mass production.

What are high-tensile materials?

A high-tensile material refers to a high tensile strength steel material. In general, a high-tension material is steel sheet that has pulling strength (material strength) greater than 340 Mpa.
Unipres provides our customers with parts that are both strong and lightweight that are made from high-tensile materials.

While a high-tensile material keeps sufficient strength even after thinning the sheet thickness and weight reduction, it is difficult to process and mold, and requires advanced press technology.
We have acquired high technological skills and know-how through joint research with our customers and steel manufacturers and through our own research and development, and we have been working to manufacture many parts made of high-tensile materials.
High-tensile materials are applied in about 60%*1 of our major structural parts, and we plan to expand the application of high-tensile materials in the future.

Supply Chain Efforts

■Green procurement activities

Unipres established the Unipres Green Procurement Guidelines in April 2009.

The guidelines have set forth our commitment to reduce the impact on the environment when materials, parts, and sub-materials are delivered by our supplies. In this way, Unipres promotes global environmental conservation activities with an aim to create a society that enjoys sustainable development throughout the supply chain.

■Initiatives for substances of very high concern

With the understanding and cooperation of our suppliers, Unipres keeps track of the content of substances of concern and of very high concern*1 and provides reports to our customers.

In addition, in order to respond quickly and appropriately to tightening regulations on chemical substances in each country (including PRTR Regulations, domestic chemical substance-related laws, European ELV Directives*2, and REACH Regulations*3), we have established the Chemical Substance Control and Green Procurement Committee to share information and consider countermeasures as needed.

*1 Substances that, as set out in Article 57 of the REACH Regulations, carry a high degree of concern for human health and the environment, including CMR (carcinogenic, mutagenic, and reprotoxic substances), PBT (persistent, bioaccumulative, and toxic chemicals), and vPvB (very persistent and very bioaccumulative substances).
*2 ELV = End-of Life Vechicles.
A directive that aims to promote waste reduction to reduce impact on the environment by preventing waste generation by vehicles in EU countries and promoting the recycling, reuse, and other types of reproduction of used vehicles and their parts.
*3 REACH = Registration,Evaluation,Authorization and Restriction of Chemicals.
A regulation that aims to control the use of chemicals in order to protect human health and environment in European countries. The regulations require that business operators that manufacture or import more than one ton of substances (including the ones being dispensed) in the EU not only complete registration procedures, but also implement authorization, restriction, and notification under various conditions.

Production Efforts

■Reduction of CO2 emissions

Unipres has been working on energy conservation activities in its Offices and Plants to promote CO2 emissions reduction and the efficient use of energy resources.
We will promote the reduction of this number by implementing further energy conservation measures such as adopting production equipment with high energy-saving effects, and undertaking measures to improve the efficiency of production processes.

■Energy conservation activities

Introduction of energy-efficient transformers Use of a gas heat pump for air conditioning  Introduction of cogeneration system

We install transformers with less energy losses when we need a new transformer or replace an old one in an effort to save energy. Currently, our Tochigi Plant in Mooka and Fuji Plant in Fujinomiya have these energy-efficient transformers

Our Tochigi Plant in Mooka has replaced its boiler for indoor heating with a gas heat pump (GHP) that uses municipal gas. Since the GHP is designed to recover exhaust heat, which was conventionally discarded, we hope that the use of it will help us save more energy.

The Sagami Office introduced a cogeneration system using city gas as fuel. By switching from a conventional heavy-oil-fired hot-air boiler, it has become possible to recover exhaust heat and achieve an energy reduction of about 14%. In addition, as the system uses city gas as a fuel, which is considered to be disaster-tolerant, we can expect early recovery from damage caused by an earthquake or other disturbance.

Distribution Efforts

Although Unipres is not subject to the specific business operators of specified shippers*1 stipulated by the energy conservation law, we work independently to conserve energy in matters related to logistics.

*1 A shipper whose freight ton kilometers is over 30 million. A specific business operator is required to submit a periodic report as defined by the energy conservation law, as well as a written plan including the shipper's energy conservation activities as they relate to logistics.

■Reduction of CO2 Emissions through Improvements in Distribution

We have been working on distribution-related energy conservation measures by setting a CO2 emissions reduction target each fiscal year.

■CO2 Reduction via Modal Shift

We have switched from truck-based transportation to rail freight and ferry transportation to mitigate impact on the environment through reduction of CO2 emissions, and through other means such as alleviating traffic congestion to prevent air pollution.
According to Japan’s Ministry of Land, Infrastructure, Transport and Tourism, CO2 emission per transportation unit for rail freight and ferry transportation is approximately one-eleventh of the emission for commercial truck-based transportation. *
Unipres’ rail freight and ferry transportation in FY2019 amounted to 10,510,000 ton-kilometers. If one compares the resulting emissions with emissions for equivalent transportation by truck, it appears that the modal shift resulted in a CO 2 emissions reduction of approximately 1,149 tons.

* CO2 emission per transportation unit is the volume of CO2 emitted when transporting 1 ton of freight 1 kilometer. The ratio refers to relative emission volumes in FY2017.

Office and Plant Efforts

■Introducing Renewable Energy

As part of our strategy to reduce emissions of greenhouse gases, we are introducing photovoltaic power generation. Having installed photovoltaic power systems at our Fuji Office, our Fuji plants in Fuji and Fujinomiya, and our Tochigi plants in Oyama and Moka, we are now generating electricity.
At our Tochigi Plant (in Moka) for example, we are able to supply almost all the energy used in the administrative building. The generated electricity is also used to charge the Company’s Leaf electric vehicles and as an emergency power supply during power cuts.
In FY2019, Unipres as a whole generated 190,384 kWh of electricity, all of which was used within the Company. This resulted in an annual reduction in use of fossil fuel (crude oil) of approximately 50 kl, as a consequence of which annual CO2 emissions were cut by some 89 tons. This is equivalent to the amount of CO2 absorbed by 6,364 cedar trees in a year.*

*Calculation was based on the assumption that the amount of CO2 absorbed by one cedar tree was approximately 14 kg per year (Estimated from Measures to Promote Forest Carbon Sinks to Prevent Global Warming by the Ministry of the Environment and Forestry Agency)

■Switching to High-Efficiency Lighting

In order to promote CO2 emissions reduction through energy conservation, we are switching to high-efficiency lighting in our offices and plants. By FY2018 we had replaced all ceiling lights at our plants in Oyama, Moka, Oppama, Sagami, Fuji, and Fujinomiya with LED lighting. As a result we succeeded in reducing electricity use by up to one fourth while providing better illumination.

■Implementation of green curtains

We use green curtains to plant bitter gourds and loofahs on the wall of the offices. Green curtains have shading and cooling effectsthanks to the actionof transpiration, which contributes to energy conservation as a result of reduced use of air-conditioners.

■Introducing Leaf, the company-owned electric vehicle

Unipres has been working to reduce emissions of exhaust gas arising from burning gasoline and CO2 by introducing an electric vehicle, the Nissan Leaf.
We manufacture components such as car body structural parts, battery cases and plastic undercovers for the Nissan Leaf, and contribute to the improvement of automobile fuel efficiency through the creation of lightweight products and the promotion of zero-emission vehicles.
