The necessity of using plastic metal separator

Plastic metal separators are mainly used to detect and separate all metal impurities in industrial products.

The cost involved due to the impact of metal debris: production stoppage, reduced production efficiency, late shift production is particularly prone to failures, shortening the service life of parts, production losses, overtime, and scrap; quality problems: increased product failure rate; maintenance costs ; Increase the manpower; increase the cost of spare parts.

The use of plastic metal separators can not only remove ferrous metals (as small as 0.2 mm), but also separate other metal impurities such as stainless steel, copper, and aluminum.

Advantages of plastic metal separator

Perhaps, the purchase of a plastic metal separator should consider issues such as increasing the budget and modifying the feeding system, but it will definitely improve product quality, increase automation, and increase the waste disposal rate. In many cases, the cost of avoiding a failure may exceed the investment in the plastic-metal separator. Reduce downtime, increase production efficiency; reduce maintenance and repair costs, extend the service life of production equipment; improve customer satisfaction with products.

In the production process, there are many links that may cause metal impurities to be mixed into the material, such as: the raw material itself contains metal impurities, the metal parts from the maintenance or loading site, the metal wear of the production machine itself, and the metal ornaments worn by the operators.

a) New materials without metal impurities:

There is no metal impurity, which is inherently problematic. 100% metal-free and 100% safe, this is unrealistic! Even if such a raw material without metal impurities can be found, the possibility of metal impurities being mixed into the finished product in the subsequent processing cannot be completely avoided.

b) Recycled materials:

Usually recycled materials contain a lot of metal impurities, especially non-ferrous stainless steel, copper, aluminum, tin and so on. In view of the current increasing price of raw materials, the cost advantage of recycled materials is quite attractive to many companies, which is why more and more companies are interested in the pretreatment of recycled materials. In the regeneration process, the recycled material processing system must take into account the unfavorable factors of these metal impurities, and also use plastic plastic metal separators

c) Wear, accident or negligence

As far as the storage and supply of materials are concerned, often due to negligence or accidents, such as original ball pens, lighters, wrenches, coils, bolts, nuts, rivets, cleaning utensils, etc. are mixed into the raw materials; others, such as from the wear and tear of moving parts Metal etc. Such a thing can happen all the time, it is unpredictable.

For example, the metal impurities contained in plastics usually have the following adverse effects: block the nozzle of the injection molding machine, damage the screw of the injection molding machine, scratch the cylinder, damage the mold, scratch the product, block the hot runner of the mold-flow blockage , Increase the difficulty of dissolving the material. Metal debris affects normal production and operation: damages the machine, affects product quality, causes customer complaints, damages the market image, and causes the recycling of market products.
