The injection mould is the key tool for injection molding. If the quality of the mould goes something wrong, for example, their each position has changed, the molding surface has become rough and shape has changed. These situations happened will affect the quality of the mould. Therefore, operator must notice the correct use of the [...]

Gas-assisted injection molding is a newly-established injection molding technology. Gas-assisted injection molding working principle is to produce a hollow section inside the plastic products by high pressure gas. Instead of injection pressure maintenance, gas-assisted injection molding uses gas pressure maintenance to eliminate products sink mark and complete injection molding process. Gas-assisted injection molding process includes [...]
There are totally 5 points for injection molding conditions: Injection molding conditions 1 The large molecular structure of polymer and the features of molecular thermodynamic movement have determined that polymer has such states of aggregation as the glassy state, highly-elastic state as well as viscous flow state etc. The transformation of aggregative state is influenced [...]
