What is the way to feed plastic molds?
1. Side gate
The side gate of the plastic mold is generally opened on one side of the mold, and the parting surface is filled from the inside or the outside. The cross section is mostly rectangular, which is suitable for one mold with multiple cavities.
2. Latent gate
The latent gate of the plastic mold is inclined and lurks on the parting surface. (Shanghai Plastic Mold) can automatically cut off the pin point gate when the glue is inserted on the side or inside of the product, which is suitable for automated production.
3. Ring gate
The annular gate of the plastic mold expands along the entire outer circumference of the product to feed the glue. It can make the plastic fill the mold uniformly around the core, have good exhaust, and reduce the bonding line, but it is difficult to remove the gate. It is suitable for thin-walled and long-tube products.
