I. A Transformational New Chapter
In 2015, TASU made a pivotal strategic decision to shift from the plastic shoe sole rotary machine sector and fully commit to the R&D and production of fully automatic rubber injection shoe sole machines. Founder Wang Guohua emphasized, “Technological innovation is our foundation—we aim to lead industry transformation.” The company boldly abandoned its long-established TPR/TPU shoe manufacturing equipment business, embarking on a challenging journey of exploration.
II. Breaking Through R&D Challenges
- Independent Exploration Struggles
In the early stages, the industry offered few reference technologies, forcing the team to rely on their own experience. Frequent intellectual property infringements compounded difficulties in market promotion and IP protection, creating immense pressure. - Market Acceptance Hurdles
As a newcomer, TASU lacked a stable customer base. Clients were skeptical about the new technology, equipment performance, and stability, leading to scarce orders and severe operational challenges. - Heavy Financial Investment
From 2015 to 2019, TASU invested approximately ¥20 million to overcome technical bottlenecks. While attracting top talent, each R&D breakthrough and equipment upgrade strained finances.
III. Pinpointing Industry Pain Points
- Shortcomings of Traditional Compression Molding
- Labor Intensity: Workers endured high temperatures and poor insulation, leading to physical exhaustion and difficulty attracting younger workers.
- High Energy Consumption: Excessive electricity usage drove up production costs.
- Material Waste: Low material utilization increased expenses and conflicted with sustainability goals.
- Low Efficiency: Complex processes slowed production, weakening competitiveness.
- Key Rubber Injection Challenges
- Precision Temperature Control: Required maintaining ~80°C to ensure flowability while preventing premature vulcanization.
- Injection Accuracy: Pressure and temperature coordination was critical for product consistency.
- Backflow Issues: TASU’s innovative cold runner design eliminated defects, reduced waste, and streamlined production.
IV. A Strategic Partnership Emerges
Vibram, a leading rubber sole brand, faced high defect rates (>30%) with existing partners. After seeing TASU’s equipment resolve air-pocket issues for client Ruida, Vibram initiated testing.
“Finding the right partner was tough—TASU was a game-changer,” said Sofia, Vibram’s R&D Manager.
V. Impressive Testing & Validation
Vibram conducted rigorous trials, scaling from 50 to 100 pairs. After two days, Director Jin praised: “TASU’s team is exceptional—their equipment’s stability, temperature, and material control surpassed all previous partners.” Vibram then recommended TASU to suppliers.
VI. Advancing Collaboration
After two years of discussions, Vibram’s Guangzhou R&D center ordered a ¥1 million “Super Workstation.” TASU assembled a dedicated team, with CEO Wang stating: “We refined solutions through repeated exchanges to exceed expectations.” The project was successfully delivered.
VII. Strengthening Ties Through Visits
Vibram’s R&D leaders toured TASU’s factory, engaging in deep technical discussions. The team’s keen interest in advanced processes solidified mutual trust.
VIII. A Model of Success
Vibram’s leadership noted: “Our standards are extreme—TASU didn’t just meet but exceeded them.” This partnership is not only a commercial triumph but also a benchmark for innovation-driven industry progress, unlocking new possibilities in rubber injection molding.
