High pressure
Ecológica AP high-pressure metering machines
Impingement mixing at high pressure with a self-cleaning head and no solvent flushing.
Automotive suppliers
The project starts from the part requirements.
Seats, backrests, headrests, steering wheels, trims and filters.
The process
How polyurethane is used in automotive
Polyurethane is in seats, backrests, headrests, steering wheels, gear knobs, dashboards, trims, suspension components and filters. Each part has its own material, density, finish and cycle.
Sulpol has supplied equipment and lines to the sector since 2004, according to the company’s history, and continuously develops automated systems to shorten cycle times.
Steps
Typical process flow
- 01 Mould Preparation, release agent and inserts.
- 02 Metering High or low pressure depending on the part.
- 03 Pour Open-mould pour or closed injection.
- 04 Curing Mould time and temperature.
- 05 Demoulding Removal and finishing.
Reference flow. Each project defines the steps included and each supplier’s responsibilities.
