Requirements: 1.of plastic mold. The melting temperature range of plastic wide, not sensitive to temperature, viscosity and volatility of smaller changes with the molding temperature. Excellent thermal stability at high temperature, and has good fluidity at low temperature.
2.pairs of pressure sensitive, plastics are not governed by the pressure does not flow, but a little pressure to flow.
3.has high thermal deformation temperature, and at higher temperature can be rapid condensation, so as soon as possible and the introduction of plastic parts, not deformation, to shorten the molding cycle.
4.small specific heat capacity. Not only can rapid condensation, and can quickly melt. Heating runner injection mold can be molded most thermoplastics, but only the polyethylene and polypropylene is insulated runner injection molding materials ideal. |
