Revolutionizing Automotive Rubber Hose Production with 56% Lower Costs and 80% Higher Efficiency
INTAMSYS 3D Printing Delivers Precise Solutions for High-Temperature Applications In the automotive industry, rubber hoses function like "blood vessels," running through engine, fuel, and cooling systems to transport fluids, provide insulation, and absorb vibrations. These hoses must endure high temperatures and pressures while adapting to complex spatial geometries, placing high demands on mold manufacturing.
Bottlenecks of Traditional Metal Molds: Unable to Meet Both Precision and Customization
In automotive engine and cooling systems, rubber hoses must withstand high temperatures, pressure, and complex installation geometries. This places strict requirements on mold accuracy, thermal stability, and production speed - areas where traditional metal molds increasingly fall short.
Conventional metal molds face several limitations:
- Thermal deformation above 200 °C, leading to inconsistent wall thickness and sealing issues
- Limited design freedom for curved and twisted geometries, often requiring multi-part assembly
- Long lead times and high costs, typically taking weeks to manufacture
- Corrosion risks when exposed to fuel, lubricants and other chemicals
- These issues make traditional molds unsuitable for rapid development and small-batch production.
The INTAMSYS 3D Printing Solution
The INTAMSYS FUNMAT PRO 610HT industrial 3D printer, combined with PEI1010 high-performance engineering plastic, offers a mold-making approach that balances precision, efficiency, and reliability for high-temperature rubber hose forming.
The FUNMAT PRO 610HT provides a stable high-temperature printing environment (up to 300 °C heated chamber and 500 °C nozzle), ensuring reliable printing of PEI1010 and other advanced thermoplastics.
PEI1010 offers:
- Continuous heat resistance above 200 °C
- High dimensional stability and mechanical strength
- Approximately 60% lower weight than metal
- Excellent chemical resistance
Key Benefits
- High-temperature dimensional accuracy: Critical mold dimensions remain within ±0.1 mm, ensuring consistent hose quality.
- One-piece manufacturing of complex geometries: Curved and twisted designs can be printed directly, eliminating assembly steps and improving flow performance.
- Shorter lead times and lower costs: Mold production is reduced to 1–2 days, enabling fast iteration and customization.
