Features of Two Template Injection Molding Machine
Two-plate mold (one-time parting mold):
Generally, it is divided into a fixed template and a moving template at the parting surface.
1. After molding, cut off the molded product and the sprue, and process it (such as: side gate, straight gate).
2. Simple structure and easy to use.
3. It is suitable for the product to fall automatically. (latent gate, no post-processing required)
4. Few faults and low price.
Injection molding is a cyclic process, each cycle mainly includes: quantitative feeding-melting and plasticizing-pressure injection-filling and cooling-mould opening and taking parts. After taking out the plastic part, the mould is closed again for the next cycle.
The time of Ouco Injection molding process is 18 seconds.
