This MUD Quick-Change frame series features a center runner bar for
simultaneous molding with two standard-style companion insert molds.
The series offers cost reduction benefits and time-saving advantages
Quick-Change similar to the U frame series. It also provides comparable design flexibility.
H frame options
The two companion insert molds for H frames can be changed independently
n Spring-loaded master ejector plates and individually. A dummy insert is supplied for single insert mold production.

n Interlocking ejector rails This results in exceptional versatility for tailoring schedules to virtually all
inventory requirements including just-in-time delivery.
n Additional height on ejector rails

n Early return on ejector system H frames also offer special advantages for high volume production. Two insert
molds permit doubling quantities for each molding cycle. Also, there is virtually
n Special knockout hole locations
no need to interrupt production for maintenance or repair since inexpensive
n Runner shutoffs backup insert molds can be quickly installed.
n Choice of runner configuration
H frames are supplied with hardened center runner bars and replaceable
Frame spacer bars
n sprue puller pin assemblies. Each frame includes a locking locating ring and

NOTE: Specifications subject to change Quick-Change Hot Runner Molding
without prior notice. All of the advantages of the MUD Quick-Change Concept can be added to
a hot runner molding system with the addition of a manifold to the H frame.
Both the frame and the hot runner system remain in the molding machine.
Only the insert molds are changed to produce new parts, just as in other
Quick-Change applications. This means faster changeovers, lower tooling
costs and greater scheduling flexibility for hot runner molding.

Steel specifications: Standard frames are produced in prehard steel
(285-325 Brinell) with hardened center sections. Frames are also available in
prehard stainless, 420 stainless, H-13 and other grades on request. Frame
coating can be specified.
