Hand De-Gate

This is where castings are broken off from the gate of the runner feed and separated from the die casting shot. Die castings are produced on a runner feed and hold the die castings to the feed. The common term is the die casting shot.

The feed is designed at its thinnest point which connects the feed gate of the runner feed to contact the casting. Commonly known as the point of contact.

The feed is designed to fill the casting impression and is designed at point of contact to be the weakest part of the feed and allows the runner feed and casting to be manually separated cleanly and reliably every shot.

Castings are placed in work containers. Runner feeds go into a scrap bin and recycled by melting in a furnace. this process is done in house and keeps waste to below 1%. We are then able to re-use the runner feeds in our die casting process.

The die casting shot is held in one hand and the operator uses their other hand to break the castings off the runner feed. The process is operator friendly and requires a small amount of pressure to separate the 2 parts.

The process is reliable and repeatable and can be done several 100 times per hour making it very cost effective. The positive to this method it saves making press trim tools and maintenance of the press tool costs through the product.

Yes, manual hand de-gate will essentially be cheaper as you will not have to purchase a press trim tool.

Pressure die casting with zinc-based alloys is one of the most efficient and versatile high-production methods used for the manufacturing of strong, accurate, complex and intricately shaped metal components. Each component which is produced using this method is attached to a sprue, runner feed and will have gates/risers. All Zinc pressure die castings will need a secondary operation. Whether it be hand de-gate or press trimmed.

This is dependant on the shape and form of your component. Some shapes and sizes are better suited to a press trim operation. If your component needs to be completely flash free then a press trim operation will be a better-suited option.
