com) demonstrated an interesting technique called Sequential Cavity Separation (SCS), which uses valve gates in a family mold
to inject two similar or different parts in sequence.
A conventional process takes seven steps, molding two part halves in a family mold
Executed within the early stages of mold design, Mold Adviser allows users to create and analyze sprues, runners, and gates in single, multi-cavity, and family mold
One new job in development will use a 16+16 cavity family mold
to produce two different parts with independent hot runners.
Mr Klecker incorporated the data generated when creating the mold design to build a family mold
that was used in the manufacture of the buttons, LED spacer, and mounting clips.
TRIAL 2: HIPS family mold
(2 parts), 2 cavities, 310-ton press.
Using standard DME Flex manifold heaters for improved displacement of heat, the Zenith HRS is an excellent choice for sequential filling and family mold
At NPE 2006, Three non-circular gears and a base plate of DuPont Delrin acetal were made in a family mold
on an Engel tiebarless e-victory press.
DME Company reports that it has recently expanded its line of hot-runner products and services with the launch of the Unitized Open Gate Hot Runner System, "a high-precision system that comes pre-wired for fast, easy installation," noting that "For customers who don't need a full hot half system with plates--but still want something with minimal setup time--the DME Unitized Open Gate Hot Runner System is an ideal midway solution that reduces labor in sequential filling and family mold
The base unit is injection molded in a family mold
in two halves.
This part was molded in ABS/PC in a 1 +1 family mold
