Product Overview
Specially designed for the precision production of polyurethane steering shaft ball sockets for the automotive industry, widely suitable for the casting of passenger and commercial vehicle steering system parts.
This PU casting unit is purpose-built for the precision production of polyurethane steering shaft ball sockets used in automotive steering systems, for both passenger and commercial vehicles. The 1A1B independent temperature control two-component system supports flexible switching between MOCA and BDO chain extenders, allowing adjustment of hardness to suit ball sockets for different vehicle models. Dynamic full-range high-precision metering ensures small product size error, in line with automotive parts assembly standards. The small-flow precise casting capability (30–600 g/s) delivers stable forming without burrs, effectively improving the yield of small parts. With simple and stable operation, the machine is ideally suited for mass production of multi-specification auto parts, meeting the requirements of high-precision assembly, long-term durability, and stable steering. Vacuum defoaming (≤-0.095MPa) ensures dense, pore-free products.
Operation Workflow
Raw Material Preparation
Prepare CPU prepolymer and chain extender (MOCA or BDO) at the target mix ratio (MOCA: 100:9-12; BDO: 100:3-6), selecting the formula for the required hardness and vehicle model.
Tank Loading & Independent Temperature Setting
Load prepolymer into Tank A and chain extender into Tank B; the 1A1B temperature control sets Tank A at 30-80°C and Tank B per formula (MOCA: 90-115°C; BDO: 25-50°C).
Vacuum Defoaming
Activate the vacuum defoaming system to reach a vacuum level ≤-0.095MPa, removing bubbles for dense, pore-free ball sockets with consistent mechanical properties.
Precision Metering, Mixing & Small-Flow Casting
The PLC metering system dispenses precisely; the mixing head runs at 8000-12000 r/min, with small-flow casting ensuring stable forming without burrs for small ball socket molds.
