Adopting supercritical nitrogen physical foaming process without chemical foaming agents, with nitrogen extracted from air for recycling use, this equipment delivers prominent low‑carbon advantages for midsole production to cut carbon emissions and reduce finished‑shoe carbon footprint, helping factories satisfy EU carbon tariff access standards.

it realizes clean production with no harmful chemical additives and zero volatile pollutant discharge during forming, the closed‑loop nitrogen circulation system minimizes raw material waste while leftover foaming materials can be recycled and reprocessed to lower solid‑waste output and establish a circular production mode, its stable low‑emission production process supports complete carbon emission traceability reports to assist shoe manufacturers in supply‑chain environmental disclosure and smooth passing of sustainable procurement audits from international sportswear brands, besides, the centralized automated rotary structure reduces manual repetitive labor intensity and the fully‑enclosed pipeline layout cuts workshop noise and dust for better occupational health protection of front‑line operators and higher overall factory safety standards, and it is widely applied for high‑rebound EVA/PEBAX/Bio‑EVA running shoe midsole injection foaming molding, mass continuous production of thick midsoles for lightweight casual sneakers and dad shoes, standardized forming processing of shock‑absorbing midsoles for children’s footwear and safety shoes, custom foamed sole production for yoga shoes, beach shoes and outdoor sports footwear, small‑batch customized development of special‑performance foam soles for brand customers, as well as industrialized forming of low‑carbon bio‑based sole materials for sustainable material production lines.

To address the challenges faced by ASEAN footwear factories, including high energy consumption in traditional chemical foaming processes, excessive material waste, inconsistent sole-weight control, and limited production efficiency, our new-generation Multi-Station Supercritical Nitrogen Physical Foaming Injection Molding Machine for Footwear Soles will be presented at VFM 2026 Vietnam.

As one of the key exhibits at the Vietnam Footwear Machinery Exhibition from October 14 to 17, 2026, the machine is designed for Southeast Asian footwear manufacturers and supply-chain companies visiting the footwear machinery and materials exhibition at SECC in Ho Chi Minh City.

The equipment integrates precise supercritical nitrogen metering, material plasticizing and mixing, multi-station rotary injection, and automated sole molding in one production system. It is suitable for manufacturing lightweight footwear soles and performance midsoles using TPU, TPEE, PEBA, EVA-based compounds, and other thermoplastic materials.

Through physical microcellular foaming technology, the machine can help footwear factories reduce product density and raw-material consumption while improving cell uniformity, rebound performance, and production consistency. It also reduces reliance on conventional chemical foaming agents and supports the transition toward lighter, more automated, and cleaner footwear production.

This solution helps manufacturers address common production challenges such as high material costs, unstable product quality, and difficulties in the mass production of high-performance midsoles.

Footwear manufacturers, sole factories, and machinery buyers from around the world are warmly invited to visit VFM 2026 at SECC in Ho Chi Minh City and experience this supercritical nitrogen physical foaming injection molding system from October 14 to 17, 2026.
