SYNDAR plastic metal separator prevents metal impurities from harming injection molding machines and extruders

SYNDAR plastic metal separator prevents metal impurities from harming injection molding machines and extruders

Issue Time:2020-10-27

The plastic metal separator can separate magnetic or non-magnetic metals (such as stainless steel, aluminum, copper, lead, etc.) from slow flowing materials. It can be installed directly on the feed port of the injection molding machine, or used alone.

 

The price of metal impurities?

In terms of production: reducing production efficiency, shortening the service life of equipment components, temporary shutdowns, disrupting normal production arrangements, and increasing waste

In terms of quality: the rate of unqualified products has risen and the risk of product recalls

In terms of maintenance: increase maintenance personnel and increase parts costs

 

The harm of metal impurities?

In terms of injection molding and extruder: damaged screw, scratched cylinder, blocked nozzle

In terms of molds: block the mold runner, flow blockage, block the hot runner, increase the difficulty of dissolving materials, and metal scratch the mold

Product aspect: The finished product contains metal, which causes short circuit and non-insulation, and scratches the surface of the product

In terms of crushing processing: damage to the crushing blade, resulting in more metal fragments

In terms of polishing and calendering system: damaged, knocked calender roll


Where do metal impurities come from?

Manual feeding and opening of material containers

Use contaminated recycled materials

Broken blades or iron filings generated by lathe cutting

The negligence of the staff

Flaked or ground materials from conveyor pipes

Avoid malicious damage

 

How to prevent metal impurities from harming the injection molding and extruder?

Systematic metal detection and separation technology can solve this problem

The detection and separation system of the plastic metal separator can detect and separate magnetic and non-magnetic metals, such as stainless steel, aluminum, copper, and lead.

Various products of plastic-metal separators are suitable for all applications in the rubber and plastic industries, and provide overall solutions according to the specific needs of customers. Thereby ensuring the safety of production, improving productivity and product quality, protecting production equipment and reducing maintenance costs, and ensuring continuous and efficient production.

 

Plastic metal separator product description

The plastic metal separator can separate magnetic or non-magnetic metals (such as stainless steel, aluminum, copper, lead, etc.) from slow flowing materials. It can be installed directly on the feed port of the injection molding machine or used alone. Products can

It is widely used in mining, smelting, food, medicine, textile, chemical and other industries!

 

Working principle of plastic metal separator

Plastic metal separators only provide maximum metal detection and separation. Instead of 100%. Due to the impact of material transportation and material conditions, and the environmental impact around the equipment, etc., metal missed detection and metal particles are not separated.

When there is too much metal, which leads to too much detection signal, the separation baffle is too late to open and close

The materials are conveyed by pipeline or vacuum suction

Feeding methods that are too fast. Automatic feeding device is not recommended


Working steps of metal separator:

The raw material passes through the detection system in a falling body. When metal is detected, the removal slider is immediately activated, and the raw material containing metal particles is pushed to the waste port and separated.

 

Application characteristics of plastic metal separator

Detected product: bulk material, no conductivity

Material requirements: dry, good fluidity, no fiber

Installed in: Bulk material flow and free fall environment

Use industry: plastic industry, rubber industry

 

Application characteristics of plastic metal separator

Special removal mechanism can ensure the rapid and accurate separation of metal particles

Compact design, easy to integrate in the inlet of extruder, injection molding machine, blow molding machine

Suitable for drying, good fluidity, no long fibers, no electrical conductivity, particle size <10mm

The material temperature is less than 80°C, and the temperature exceeds this range. If you can choose a special high-temperature option to add a plastic metal separator, you must consider issues such as increasing the budget and modifying the feeding system. But it will definitely improve product quality, increase automation, and increase waste utilization. In many cases, the benefits of avoiding an accident often greatly exceed the investment in plastic-metal separators. The use of various products of the plastic metal separator ensures the safety of production, saves customers' costs, achieves the purpose of energy saving and consumption reduction, improves productivity, and ensures continuous and efficient production. Choosing various products of SYNDAR plastic metal separator technology can help you recover the investment cost in the shortest time.

    The difference between dynamic checkweigher and static checkweigher
    Checkweigher is a kind of automatic checkweighing equipment widely used in the production line of pharmaceutical, food, chemical and other industries. It can detect overweight and underweight unqualified products in the production line in real time online. The weighing methods of weighing equipment are divided into dynamic and static weighing methods. What is the difference between them, let's understand together below:
