Haifeng successfully engineered and commissioned an automated agricultural support vehicle wheel molding workcell for a leading farm machinery manufacturer in Morocco, achieving 100% chemical corrosion resistance against aggressive fertilizers and pesticides while eliminating field puncture downtime. The project encompassed a high-pressure dual-component dosing machine, precision multi-segment hydraulic tire clamping stations, dynamic oil temperature conditioning skids, and automated rim preheating tunnels.

Prior to commissioning, farmers operating high-clearance sprayers and field support tenders faced costly operational delays. Sharp rocks in rough North African fields ruptured pneumatic narrow tires, while acidic agrochemicals rapidly embrittled rubber casings and oxidized valve stems. The client required an advanced chemical molding solution capable of casting narrow, high-diameter microcellular polyurethane tires directly onto heavy steel disc wheels, delivering high ground clearance, reduced mud sinkage, and complete resistance to pesticide corrosion.

Operating since November 2023 on a two-shift daily schedule across a 300 m² footprint, the workcell delivers consistent component repeatability. By implementing Haifeng's closed-loop Ratio Lock flow algorithms and dynamic mold thermal balancing, the client reliably manufactures high-clearance, puncture-proof farm utility wheels that keep sprayers operating smoothly through critical crop protection windows.

Project Technical Specification Matrix:

Haifeng deployed a high-precision reaction injection tire platform engineered for narrow, high-diameter crop protection wheels:

1. Precision High-Pressure Stoichiometric Dosing: Servo displacement pumps meter specialized hydrolysis-resistant precursors at 180 bar with ±0.5% precision.
2. Radial Multi-Segment Hydraulic Clamping: Hydraulic presses close precision 4-segment aluminum tooling, holding tight parting lines across deep mud-shedding tread lugs.
3. Dynamic Mold Oil Thermal Management: Closed-loop TCU units maintain mold temperatures at 60°C (±0.8°C), ensuring quick, uniform microcellular curing without internal voids.
4. Solvent-Free Anti-Drip Mixing Head: An L-shaped impingement head executes rapid 0.3-second needle cut-offs without chemical solvent flushes, maintaining clean tool definitions.

Installation and commissioning: 18 days. Operator training: 4 days. Warranty: 1 year. Long-term spare parts and remote PLC diagnostic support are available.
