Description

CK-42HT Laboratory Underwater Pelletizing Compounding System is designed for laboratory purpose, especially for experiments on the materials that have low melting temperature and high viscosity.


Possible materials :
TPU, TPE, TPV, TPR, PP, PS,  PLA, PVA, SEBS, EVA, Rubber, Hot-melt adhesive, Special resin, and Micro pellets, etc.

Outline

How it works :
①Hopper ➜ ②Loss-in-weight feeder ➜ ③Side feeder ➜ ④Plastic extruder ➜ ⑤Underwater pelletizing system ➜ ⑥Centrifugal dryer ➜ ⑦Storage tank

According to the forms (pellet, powder, liquid) and the added proportion of the materials to determine the materials are fed into the laboratory extruder by passing through loss-in-weight feeder or side feeder. The materials that are inside of the extruder are melted, kneaded, and then cut into pellets by underwater pelletizing system. The cut pellets will be cooled and dried to become usable pellets.

  • Loss-in-weight feeder
    The loss-in-weight feeder measures the amount of materials that reduced per unit time, and automatically detects and adjusts the feeding tolerance to accurately and stably control the output volume.

  • Side feeder
    In response to various additives that may be added during experiments, such as powders or pellets. It has a self-cleaning function.

  • Extruder screw
    The extruder screw is the critical part of the plastic extruder and it can melt, deliver, and knead plastic materials. The design of the screw determines the efficiency, productivity and quality of the extrusion result.

  • Underwater pelletizing system
    The rotatory cutter cuts the melt extruded from a die. Since the die immerses in water, the cut pellets are cooled and delivered by water at the same time. This production method is suitable for the plastics with high viscosity or low MI value.

  • Centrifugal dryer
    The equipment belongs to the downstream process of underwater pelletizing system. It is to remove surface moisture on the cooled plastic pellets. By eliminating the moisture, a better quality of the pellets can be obtained.

  • Storage tank
    The storage tank is to gather plastic pellets. It is made by stainless steel.
Features

1. Flexible configuration
The CK-42HT laboratory extrusion system equipped with 2 sets of loss-in weight feeders and side feeders. The design purpose is to satisfy a variety of experiment requirements for composite materials under different conditions.


2. Supporting small batch
Small batch production of various plastic can be carried out in this laboratory system in a short time to achieve the most economical experimental tests.


3. Intelligent automated operation
The high-level human machine interface system integrates all production parameters. The smart extrusion system helps researchers to control, analyze, monitor, and adjust each production process. It is not only a smart personal assistant, but also an intelligent machine to keep operators working in a safe environment.


4. Compact, quiet, convenient storage space
The laboratory extrusion machine is built highly noiselessness and compact. It is suitable for industrial factory, educational or research institutes. The space on top of the machine can be used for storing dies and tool, which greatly saves time for production preparation.
