What Is Sprue Bushing Type B?
A sprue bushing provides a pathway between molding machine nozzles and the mold. Specifically, a sprue bushing includes an opening that mates with a nozzle.
To ensure a proper fit between the sprue bushing opening and the nozzle, the opening and nozzle must have the same diameter opening and the same spherical radii.
Performance Sprue Bushings The wide range of Steel Sprue Bushings allows molds to be installed in a variety of injection molding machines. The accuracy and interchangeability of the products permit easy replacement if the mold is being transferred to another machine.

An injection mold is a mold that is produced at high temperatures. In the process of injection mold processing, an important mold accessory – is the Sprue Bushing. Also called the sprue sleeve.
The injection mold can shorten the molding cycle of the part, and the production cycle of the thin-walled parts can be less than 5 seconds. If there is no cold runner in the injection mold, no waste will be generated, which will reduce the cost of raw materials and make it more environmentally friendly.
The product is molded in an injection mold， the plastic melt temperature is accurately controlled in the runner system. Plastics can flow into the cavities in a more uniform state, which results in better-quality products.
If the quality of the sprue bushing is good, the residual stress will be lower after demolding, and the deformation of the part will be significantly smaller. Therefore, sprue bushing is an important accessory for injection mold.
