Types Of PU Elastomer Casting Machine
PU Elastomer Casting Machine
Yongjia elastomer machines support both MDI and TDI systems and have strong temperature and pressure control capabilities, ensuring stable product performance in hardness, wear resistance, and elasticity. They are widely used in wheels, rubber rollers, seals, industrial accessories, and other fields.
Elastomer Production Line
Yongjia’s elastomer oven production line integrates a fully automated mold conveying and oven curing system with an elastomer machine, achieving integrated production from raw material metering, mixing, pouring, and curing. It supports both MDI and TDI systems, ensuring fully cured products with stable performance. The entire line boasts a high degree of automation, making it suitable for large-scale industrial production.

How to Choose a PU Elastomer Casting Machine
A PU elastomer casting machine meters and mixes a two-component polyurethane system and pours it into moulds to make solid, dense cast parts — wheels, rollers, mine screens, scrapers, bushes and more. We build the machine; you run it with your own or sourced MDI/TDI system. Five things decide the right machine:
- Shot capacity vs part volume — large parts (screen panels) must fill in one shot before gel; this sizes the machine.
- MDI or TDI system — TDI for abrasion/dynamic parts (screens, scrapers, wheels), MDI for easier handling and firmer parts. Multi-component machines run both.
- Ratio and temperature control — accurate ratio (±1%) and heated tanks drive consistent hardness part to part.
- Component count — 2/3-component machines let you adjust hardness or colour in-line.
- Automation — mould carousels and metered pouring for volume production.
The Casting Process
Prime the metal core or insert → condition mould and materials to temperature → meter, mix and pour at the fixed ratio (fill from the bottom to avoid air) → gel and demould → post-cure to develop final properties → machine to final size. Ratio drift and trapped air are the two most common causes of soft spots and early failure.
Key Parameters
| Parameter | Typical range / note |
|---|---|
| Hardness | Shore A 60–95 (up to Shore D for MDI structural parts) |
| Mixing ratio accuracy | ±1% — the driver of consistent hardness |
| Material temperature | Heated tanks, held stable for constant viscosity/reactivity |
| System | MDI or TDI cast elastomer (2/3/multi-component) |
| Post-cure | Oven cure to reach full abrasion, tear and rebound properties |
