Plastics Auxiliary

Importance of Plastics Auxiliary equipment

In plastics processing industries like extrusion, injection moulding, calendar, hollow moulding, film blowing and spinning, the required components are host machines that meet the requirements. In contrast, the indispensable components are several auxiliary equipment’s that complete all processes. Product quality and corporate profitability, therefore, depend to some extent on the automation and rationalization Plastics Auxiliary equipment. There are three types of plastic auxiliary equipment, including feeding equipment, temperature control equipment and rim residual granulating and recycling equipment, according to the functions. And these instruments have a range of plastic process functions.

A feeding device that supplies high-quality materials

A full collection of feeding systems for the plastic process is composed of drying, conveying, measuring and mixing equipment. Drying equipment is used before moulding for pre-treatment of hygroscopic materials such as ABS, POM, PC, PA and PMMA. High drying is typically adopted during the manufacturing of polyolefin plastics to ensure product consistency. For example, material needs to be dried to the extent of moisture content in the production of tubing plus injection moulding of random copolymerization polypropylene PP-R and polyethene material for cross-linked polyethene. Different drying modes and equipment are also being applied depending on the material moisture content of different goods. The optimal equipment for the material loading of PVC granules is an oven dryer. The rotary double-cone vacuum dryer is often used for plastics with high thermo-sensitivity. But the direct-type hopper dryer is the first option for subsequent drying. Air conveying with a combination of spring coil conveying system and Roots air blower is followed concerning the conveying system of conveying powder, and a vacuum loader is ideal for conveying granules. In the large-scale and automated output, the central feeding device is often used. Computers regulate equipment in the system with all kinds of materials after proportionally passing the metering devices into mixers. Every hopper is fitted with a level sensor to detect the quantity of material in the conveying pipes, which controls the opening or closing of the material tank. In the primary feeding method, the vital technique is precise electronic scale calculation, which will impact whether the quantity of feeding material is correct or not by proportion.

Volumetric Dosing Units

Our “Mischboy” dosing units include the 500 series, the Mischboy DOAL and the MB SG 1. All volumetric fillers at Amboss+Langbein are designed for ultrafine-tuned metering of granular additives. The dosage can range from one granule up to about 20 kg/h. Theoperator has constant visual control of the process underway. All fillers are distinguished by their ease of cleaning and ability to switch from “black to white” within one minute without need for tools and without mess. We provide constant qualitative monitoring of the dosing process, with production stop in the event of dosing failure registered by external alarm.

Screw Dosers

Reynold and Amboss+Langbein The screw dosers at Amboss+Langbein are ideal for volumetric dosing of free flowing and difficult non-free flowing particles, whether granular, powder or in mixed form. Dosing is controlled by throughput or weight. A downstream free-fall mixer ensures uniform blending of inputs. One free-fall mixer can process up to four feed chambers. Blending is visually monitored. Product conversion is accomplished by simply pulling the metering screw – clean and effortless.

Dehumidifying Dryers

Reynold and Amboss+Langbein dehumidifying-dryers are available in the E series with single vessels or in the D series with double vessels. The dryer system is custom built to meet operational requirements and can be erected in very tight space-restricted areas. Dryers are dewpoint-monitored and equipped with energy-efficient heat exchangers. Individualised material monitoring prevents system overload from excessive material intake as well as plastics over-drying.

Temperature monitoring for product quality assurance

During the plastic phase, heating equipment involves cylinder moulds used for extrusion, injection moulding and rolling devices, as well as roll forming heating controls. The electrical heating of heat transfer oil is the heating technique in current use, but not the complex steam heating. In the plastic process, heating equipment primarily refers to the temperature heating controller applicable to the extrusion, injection and calendar output of cylinder moulds and stacks.

Cost-lowering recycling

There is a 5~20 per cent portion of rim leftover in the overall production quantity in the plastics process. More and more processors have recognized that the efficient recycling of these resources is of great benefit to the growth of companies. There are currently numerous commonly used plastic granulators, some of which are suitable for rigid and small-size granulate material, soft plastic foam recycling and pelleting, shredding pipe or long tubing products, and waste silk recycling. The development and study of plastic recycling equipment focus on the characteristics of low noise, simple operation and continuous central hopper feeding.
