Cutting Sprue Bushing Removes Need for Secondary Operation
DMS adds Almo’s cutting sprue bushing to its range of edge gate cutting components.
DMS adds Almo’s cutting sprue bushing to its range of edge gate cutting components. The cutting sprue bushing enables feeding plastic components near the mold’s center, virtually eliminating cold runners into a runnerless cold feed and trimming the gate as the mold opens, removing the need for secondary operation. It also provides a large edge gate area to reduce injection pressure and improve the packing and quality of the final plastic product.
Although PERC (Programmable Electric Rotating Cores System) is not a brand-new technology, it warrants a second look as a way for moldmakers to provide another value-added service to their customers.
With a firm understanding of the effects of injection on the core, slide and associated components, this second of two articles will discuss emerging modular technologies which provide alternatives to the limited solutions previously available.
