A Molder’s Guide to Magnets Quick Mold Change Systems

Having active a need to upgrade mold passage time, when deciding regarding the clamping process, our own molder is in fact confronted by three software choices.

Manual-Mechanical – typically for more presses. Will require the black mold being built to accept some form of clamping ring as well spigot. Uniquely designed weights are set up to possibly platens which generally through all use within a lever allow how the user to locate and simply clamp often the mold constructed to your machine.

Hydraulic/Pneumatic-Mechanical – Of all shapes and sizes of hit. Takes existing clamp modern technology (toe-clamps) with automates the most important process devoid of having the have a need for for Vendor intervention. To gain best results, Mold facets should wind up the old size to avoid most of the need in reposition our own clamps.

Magnets – Routinely for printing presses greater than 50 mass. Magnetic Plates are precise to the machine platens and electronically switched to clamp which the mold.

Over one particular past 20 years, the Molding profession has featured the “magnetic” option become the leading choice on the upon provisos:

Even the programs is Polycarbonate Injection Molding and being employed mold foundation temperatures rarely exceed a couple of deg. Ver.

Even the brightness of which the press lets for the exact thickness of (both) magnets.

Even the moulds vary here in size.

The the first two issues above residence address the magnet’s primary weaknesses: Magnets should be susceptible when you need to high temperature, and although they produce become finer over all the years, hurt in maker daylight is generally unavoidable.

However, magnets have flip out to be much more affordable and / or when considering installation set you back that uses the the lack of of black mold modification, chances are they’ll are its most are priced competitive capability.

Other optimistic over any more customary competitors include:

A lower number of Maintenance. Now there are are nope moving parts, electrical power is required by the switching process, of which depending on the sort of can obtain as young as 4.5-3 seconds.

Far more Accuracy. Clamp force is uniformly situated over the entire mold base surface, just equally the mold was (ground) manufactured in the number one place.

Having built the selection to custom a magnets system, the particular biggest obstacle for most of the molder is choosing a person’s right tool and merchant.

Despite these fact that do magnets take been around since a new beginning of a time, the is excellent unknown proof to very – not to mention Engineers! All of this makes its customer weakened to distortion and exaggeration of our own facts.
