Features
Specifications
The Threadformer unscrewing devices are precise, sturdy and cost-efficient
The Superior Threadformer is supplied ready for operation.
The fixed thread guide nut comes with factory-machined
internal threads matching the pitch of the thread to be
molded. Three powerful hydraulic motors to choose from,
which can deliver up to 2,450 rpm. Single-drive unit mounts
to mold using two M10 SHCS. 24 volt DC high precision
proximity switches are included for hydraulic control. All
steel parts are hardened and ground with the core holder
nitrided for extra wear-resistance.

Powerful hydraulic motor for rapid unscrewing action
Repeatable precise core stopping ability within .003” or better
Compact single and twin drive unit designs
Supports long thread depths, pitches, and types
Requires minimal maintenance for high production use
Retrofittable for new or existing injection molds
Demolds both right and left-hand threads
Can be mounted at any angle or within the mold
Our unscrewing devices provide time and cost gains in mold making while reducing
production costs for the injection molder by giving reliable, trouble-free service.
Thread Core Mounting
Simply install your threaded core into the core
holder and secure with two set screws via a
common 16mm shank system. Your moldmaker,
or Superior Die Set, can fabricate the threaded
core. Pitch should include shrinkage. Core locks
should always be used when axial pressure is
applied to the core, as in blind hole applications.

DO NOT DOWEL MOUNT THREADFORMER TO MOLD BASE
Positioning Accuracy - Brief Instruction
To guarantee a precise thread start position, the core holder must run against a fixed stop
with its entire front surface area at a pressure not exceeding 40 bar. To increase speed of unit,
maximize hydraulic VOLUME instead of pressure.
The flow of hydraulic fluid must be shut off by use of a proximity switch slightly before
the core holder touches the fixed stop.
For the core holder retraction movement, the unscrewing pressure must be higher than the
screw-in pressure. However, the unscrewing pressure should not be higher than 100 bar.
The retraction of the core holder must again be stopped by a proximity switch. This will involve some after running. Care should be
taken to ensure that the core holder does not run up against a fixed stop at this point. In case this has happened, the core holder must
be released manually. With through-thread, note that the core holder must not touch but should have up to 0,02 mm clearance upon
reaching the thread start position. This amount of play will not result in melt film formation.
