In the plastic injection molding sector, precision is critical to ensure the quality of the parts. One of the key components that influences these aspects is the magnetic platen, a device that ensures the precise and rapid clamping of molds.
In this article, we will provide a detailed comparison between two of the most prominent options in the market: the Milltec magnetic platen and the PTG magnetic platens. We will analyze their characteristics, advantages, and applications to help you choose the best option to improve precision and productivity in your plastic injection process.
What is a Magnetic Platen and Why is it Important?
A magnetic platen is a device that uses magnetic fields to securely and precisely clamp molds during the injection molding process. Unlike traditional mechanical clamping systems, magnetic platens offer a uniform and rapid clamping, reducing setup times and increasing productivity.
In addition, electropermanent magnetic platens are an evolution of this technology, as they allow the magnetic field to be activated and deactivated in a controlled manner, facilitating mold changes and improving safety in the work environment.

Frequently Asked Questions (FAQ)
What is an Electropermanent Magnetic Platen?
An electropermanent magnetic platen is a device that uses controlled magnetic fields to securely and precisely clamp molds. It allows the magnetic field to be activated and deactivated, facilitating mold changes and improving safety.
What is the difference between a Milltec magnetic platen and a PTG?
The main difference lies in the technology used. The Milltec magnetic platen employs electropermanent technology, which allows precise control of the magnetic field, while the PTG magnetic platens use permanent magnetic technology, which provides constant clamping but is less flexible.
What advantages does a Milltec magnetic platen offer?
The Milltec magnetic platen offers uniform and precise clamping, ease of mold changes, greater safety, and lower long-term maintenance costs.
Is a Milltec magnetic platen more expensive than a PTG?
The Milltec magnetic platen generally has a higher initial cost, but offers advantages in terms of precision, safety, and durability that can justify the investment.
What applications are ideal for PTG magnetic platens?
The PTG magnetic platens are ideal for applications that do not require frequent mold changes and where the initial cost is an important factor.
