Detailed Product Description: | Extrusion molding is so viscous flow state in a plastic visual detection width, at a high temperature and a certain pressure, through a die having a specific cross-sectional shape, and then at a lower temperature, shape into a desired cross-sectional shape of the continuous profiles A molded method. Visual inspection of the production process defects extrusion molding, molding material is ready, extrusion molding and cooling, traction and cut extruded Ordnance Disposal (quenching or heat treatment). In the extrusion molding process, pay attention to adjust the heating section of the extruder barrel and head die temperature, screw rotation speed, traction speed and other parameters in order to get qualified extruded profiles. With particular attention to adjust the polymer melt extruded from the die head speed. Because when low melt extrusion rate, extrudate having a smooth surface, uniform cross-sectional shape; however, when the molten material reaches a certain limit rate of extrusion molds visual protection, the extrudate surface becomes rough and dull, there shark skin, orange peel, shape distortion and so on. When the extrusion rate is further increased, the surface of the extrudate distortion, or even fragmentation, and broken into pieces or cylindrical melt. Therefore, the extrusion rate control is crucial. A complete visual inspection mechanism should include the following test items: test items Description Full bottle filling amount detected right; cover the presence or absence, height, color, whether or not skew; label presence or absence, location and identification. Detecting the presence or absence of internal packing product, placement, orientation, counting and the cover is correct. Packing boxes decorated external detection, ID, and capping positions; print product code and date / batch. Correct lid position detection cap detection: the presence or absence, height, tilt, color, seat belt integrity. Product ID verification to ensure that any product ID code exists, readable and correct. Bottleneck measurement (side to side, height and width thread) detecting the width of the glass bottleneck (E- side to side), height (H) and thread width (T). Top planar detector to check whether the vessel trimming process due to lead to uneven cutting hair, silk or wavy surface. Any defect detection Detection of contaminants on the sidewall of the container, including dust accumulation in the injection molding process to produce, scratch, stain, and built-in or surface particulate matter. Top Top test verifies hollow glass containers are not broken, chip, missing glass and debris. Also determine the presence of cork. Other detection barcode / 2D code verification, label control number (LCN) verification, tilt tag detection, knuckle tag detection, labels exist, such as mold inspection visual inspection, Sheng Ding equipment (certified), visual inspection by the Dongguan City Ding Sheng Precision Instruments Limited. Dongguan Sheng Ding Precision Instrument Co., Ltd. (www.dgshengding.com) (www.dgshengding.com) Dongguan, Guangdong, dedicated instrumentation leaders, over the years, the company implement the scientific management, innovation and development, the principle of honesty and trustworthiness, the maximum Limits to meet customer needs.
