Magnets to injection molding machine hoppers MDN

Magnets to injection molding machine hoppers Magnets for the injection molding machine hoppers belong to the main magnetic separator types. They are characteristic by several benefits: simple and easy design, not costly investment, easy handling. Above all, they find their application area in the plastics processing industry, especially in cases when regrind or crushed material is used. They are equipped with strong neodymium magnets capable of catching even very small metal impurities that may occur even inside of the plastics granulate in question.

Using the magnet in an injection molding machine hopper, injection molding nozzle lifetime may be increased significantly, saving thus big costs corresponding otherwise to the nozzle replacement. A great advantage consists in a possibility of a simple de-magnetizing by releasing of a safety screw and pulling the magnetic cores out of the stainless steel pipes.

Size models

We manufacture the models with the diameters ranging between 100 and 350 mm (the diameter of a circle drawn around the magnet).

Installation

A magnet to be used in an injection molding machine hopper may be placed simply to any conical hopper. According to its diameter, the magnet accommodates respective space in a certain hopper height on its sides. 

Magnet types

These are very strong neodymium NdFeB magnets based on rare earths; magnetic rod diameter is 22 mm.

Temperature resistance of the magnets

80 or 120 °C

Separator material used

Stainless steel 1.4301 /AISI 304/

Magnets to be used in injection molding hoppers – new UP design

Magnets to be used in injection molding hoppers – new UP design

A new, improved magnet design to be used in injection molding machine hoppers has been developed based on requirements and experience of our customers. The main difference in comparison with the standard stainless steel version consists in the fact that magnetic cores are located in a plastics corpus made of ABS (Acryl-Butadiene-Styrene) material. The plastics corpus covers the whole hopper diameter so it is warrantied that all of the material falls through the magnetic pipes (i.e. removal of “deaf” places in the standard, stainless steel version where the metals may fall down on the magnetic separator sides).

Magnetic cores are connected to the plastics corpus that leads to an improvement of the working safety during the magnet cleaning (there is no risk of injury on own magnetic core handling). Even better safety may be achieved using a universal cleaning preparation.

Magnet cleaning is performed by pulling the magnetic cores out of the plastics pipes.

Size models MDN UP

Size models

Plastics corpuses are manufactured in four size versions 280, 320, 390 and 425 mm.

Installation

Place a magnet to be installed into a hopper simply to any conical hopper. Based on its diameter, the magnet accommodates an appropriate space in a certain hopper height on its sides.

Magnet types

These are very strong neodymium NdFeB magnets based on rare earths; magnetic rod diameter is 22 mm.

Magnetic separator temperature resistance

70 °C

Separator material used

Plastics corpus is made of ABS (Acryl-Butadiene-Styrene) material.

ABS material is characteristic by a good temperature shape stability, and it has a high impact resistance even at low temperatures. It is hard and scratch resistant. It is not soaking excessively, and it has a good dimensional stability. It may be used in the temperature range of -50 °C to +70 °C.

Its disadvantages consist in a lower resistance against atmospheric factors, and conditional resistance against acids and alkalis.

ABS is commonly used in a production of automotive components, in the food industry and in the cold storage technology.
