1. Technical level and product innovation
Research and development of high-performance materials
Japanese companies such as Mitsui Chemicals and Sumitomo Chemical have been continuously introducing environmentally friendly and high-performance materials in the field of plastic extrusion. For example, Mitsui Chemicals' EPDM extrusion grade materials (such as 3072EPM) exhibit excellent weather resistance, high temperature resistance, and recyclability, and are widely used in construction, automotive, electronics, and other fields. In addition, the research and development of "lightweight" and "metal substitution" materials such as bio-based plastics and carbon fiber composites are also accelerating to meet the needs of the automotive, medical, and other industries.
Precision machining technology
Enterprises such as Japan Steel Works and Toshiba Machinery are leading in technology in the field of twin-screw extruders and precision molding equipment. They enhance production efficiency by optimizing screw design, increasing rotational speed, and boosting production capacity. For instance, the precision injection molding technology showcased by Toshiba Machinery can be applied to the high-precision manufacturing of electronic components and medical devices.
II. Market dynamics and demand
Export-oriented growth
Japanese injection molding machine export orders have seen a high growth for several consecutive months (for example, exports in June 2024 increased by 40.3% year-on-year), with the Chinese market making a significant contribution. The main demand comes from the automotive (especially electric vehicles), electronics, and daily necessities industries. Both small-tonnage (20-99 tons) and large-tonnage (500-999 tons) injection molding machines have shown outstanding growth, reflecting the downstream industry's demand for diversified processing equipment.
Environmental protection policies drive transformation
Driven by the "Plastic Resource Recycling Law" (implemented in 2022), Japan's plastic extrusion industry is accelerating its transition to a circular economy, reducing disposable plastic products and promoting recyclable materials. For instance, supermarkets and catering enterprises are gradually adopting paper straws as a replacement for plastic straws. Enterprises are required to bear the Extended Producer Responsibility (EPR) and optimize recycling technology.
III. Industry Structure and Major Enterprises
Leading enterprises take the lead
Companies such as Mitsui Chemicals, Sumitomo Chemical, and JSW hold a dominant position, with product lines covering general-purpose plastics (such as UHMWPE and PC), engineering plastics, and specialty materials. For example, Mitsui Chemicals' ultra-high molecular weight polyethylene (L8002) is used in sheet manufacturing, while Sumitomo Chemical's EVA material is applied in wire and cable.
Exhibition and technical exchange
Industry events such as PLASTIC JAPAN bring together materials, equipment, and recycling technologies, promoting the commercial application of cutting-edge technologies like "lightweight" and "ecological materials", and fostering collaborative innovation within the industry chain.
IV. Challenges and Trends
Global supply chain adjustment
After Thailand and other Southeast Asian countries banned the import of plastic waste, Japan needed to adjust its plastic export strategy, while facing market fluctuations caused by Sino-US trade frictions and the relocation of manufacturing industries in Southeast Asia.
Sustainable development direction
In the future, industries will focus on biodegradable materials, recycling technologies, and low-carbon production processes, in response to the global trend towards reducing plastic use and domestic environmental protection goals.
Overall, leveraging its technological advantages and policy guidance, Japan's plastic extrusion industry is transitioning from traditional manufacturing towards high value-added and sustainable directions, while consolidating its competitiveness in the global market through exports and technology exports.
