What is the disadvantages of injection Moulding?
1) High tooling costs and long set up lead times. Up-front costs are high due to the design, testing, and tooling required. Lastly, and only after extensive testing during both stages, you can finally injection mould a part. Jun 22, 2019.
Can polyurethane be injection molded?
Molten polyurethane is injected into a closed mold at high pressure. The high-pressure forces the polyurethane to completely fill the mold cavity.
